. Smart GraphQL clients can make interaction with the server more efficient by reducing the number of roundtrips to fetch data. So the "default" approach should probably be the one with a single useQuery and multiple query objects, not the one with multiple useQuery. Each query response is put into the cache (the corresponding request is used to generate the cache key). But there is definitely benefit with being able to declare the needs in a single query and to support the full extent of what a GraphQL document is. Queries: For those coming from the REST background, a query in GraphQL is like a GET request to a route or an endpoint. You're still talking about a static number of useQuery. However if you insist not using batch-http apollo link, you should follow @ivan-kleshnin's advice. A client-side schema gives a great “starting point” should you eventually decide to take the plunge and invest in a real GraphQL server. When we apply this query merging to the queries we just mentioned, we get the following composed query: This query is then sent down to the server and we get a result that looks like this: This does look a bit ugly, but your frontend code will never see any of this. Similar posts. Become an Apollo insider and get first access to new features, best practices, and community events. For example, one if the two queries is marking a variable as required and the second query doesn’t mark it as required, an error will be thrown in this case as the definitions are not matching. Consider .css-147bmoc{color:#7156d9;-webkit-text-decoration:none;text-decoration:none;border:none;background:none;cursor:pointer;padding:0;}.css-147bmoc:hover{-webkit-text-decoration:underline;text-decoration:underline;}leaving feedback so we can improve it for future readers ✨. Transport-level batching is easier to debug than query merging, but it requires additional server support. We wanted ensure that an application developer using Apollo Client wouldn’t have to do anything extra to get batching to happen; you should get it “for free”. We’ll also consider some next steps we can take to make batching even more awesome in GraphQL. If there are multiple queries in the queue, they are combined into one server request. I'd use the second only when it's really necessary. This will ensure my passed in "service" string ends up on the request header sent to the server. There are some downsides to this approach though. If a request only has one operation, then it can be unnamed like the following: Ever. I have two components in the tree that each call useQuery with distinct queries against completely different parts of the schema. https://www.collinsdictionary.com/us/dictionary/english/to-be-fair, https://www.apollographql.com/docs/link/links/batch-http/, https://graphql.org/learn/queries/#fragments, https://www.apollographql.com/docs/react/v3.0-beta/data/fragments/, How to run multiple queries at once using GraphQL and Apollo Client. Once the results for both of the queries have returned from the server, the QueryBatcher will resolve the promises issued for both of the queries. This is similar to how Relay works — Each component may "export" a query Fragment, then a parent component that actually makes the query is responsible for merging the query fragments into one complete query, and to make the actual query to the server. I understand and we'll call useQuery as described :) Because using GraphQL and especially Apollo client suite is so convenient, one would like to develop frontend apps in GraphQL. That's my point. Sign in Do not complain in endless discussions about adding GraphQL … It involves taking multiple queries and putting them all under a single root query. Something that worked for me was using another component : If it's helpful to anyone, here's a great resource with several approaches How to run multiple queries at once using GraphQL and Apollo Client. This way, all of the data can be loaded in one roundtrip, without any extra effort. We prefer to work with Apollo, as it has a large community of supporters, is frequently updated, and is compatible with iOS, Android, Angular, Ember, Vue, and React. The component which renders last seems to cancel the in flight /graphql request created by the first component's useQuery call. This is a feature that allows you to upload files via GraphQL mutations directly. You can wri… mm had same question i have 2 use queries in the same component fetching with different queries, but i see 2 http requests, is it possible to only make 1 request ? The first useful feature of useResult is picking one object from the result data. Although query merging is very effective, it has a few downsides. Another important improvement of GraphQL is that multiple operations can be sent and retrieved using a single endpoint (usually /graphql) and a single network request. Link: https://www.howtographql.com/basics/2-core-conc… The GraphQL schema can more easily be built incrementally based on the requirements of the frontend, rather than trying to convert your entire REST API into a GraphQL-based solution in one go. Hi, In advance thank you great library. The server has to know how to process an array of queries and respond with an array of results. Since we’re re-using the same variables in both components, if the two queries don’t accept the same variables (or their type definitions), we can’t have multiple definitions for them. In this post, we’ll first take a look at how we can use batching and then we’ll open up the box and see how it is implemented. But it turns out that caching isn’t the only thing that can make server communication more efficient. Apollo Client queries are standard GraphQL, so any query that runs in GraphiQL will also run when provided to useQuery. Because react does not allow you to have a variable number of hooks, I still think there is a usecase for ONE hook that performs multiple queries. What you want to do is compose multiple useQuery into your own custom hook: Thank you for your quick response. Next, you'll discover how to resolve queries and nest objects. Instead, imagine we submitted a request that looked like this: And the server would return a response that looks like: This is another way of accomplishing what we are currently doing with query merging: fetching the results for multiple queries in a single roundtrip. Is it possible to do the same things as compose() method defined in react-apollo? Or should we call useQuery with each queries? It becomes messy easily when it grows and difficult to pass the data around. Here's one approach (from the article above): Another simple solution I found useful is to wait on destructuring the results until you can control the name you give each value. This is something that is definitely and added bonus. While updating the UI for Meteor Galaxy to use Apollo Client, we realized how desirable it is to have query batching in a production app. Powerful local GraphQL development. So if you have previously queried { offset: 0, limit: 100 }, and now are querying the same operation with variables { offset: 0, limit: 10 }, the cache will be missed and the network will be hit. Check out Apollo Client. Those policies can be, for example: My code above (single useQuery, multiple queried objects) will result in a single HTTP request. I am using Apollo client + Graphql + React in my project and I am facing a weird issue in Graphql requests. But I will add to it: you might want to consider breaking your one query (comprised of the two smaller queries) into logical query Fragments (see links below). A common way to reduce server roundtrips is through caching, because the fastest way to load something is to already have it. Save time and build faster with features like one-click query building, intelligent search, and variable extraction. This means that if you render several components, for example a navbar, sidebar, and content, and each of those do their own GraphQL query, they will all be sent in one roundtrip. Apollo lets you automatically batch multiple queries into one request when they are made within a certain interval. I am simply renaming the fields useQuery is giving me in the first call, so that they can live in the same scope, otherwise the second query will overwrite the first. There are a lot of libraries you can use to work with GraphQL, including Relay, Prisma, URQL, and Apollo Client. Now, on the server, using express, I set up a redirect route that reads the header and sends the request on to either one or the other endpoint based on this header: graphQLServer. In the meantime, just passing an additional option to the Apollo Client constructor will let you load your UI in a single roundtrip rather than a dozen, without needing to put in any effort to manually merge queries using fragments. Apollo Studio Explorer is the GraphQL IDE of the future. Both of the queries will go through the QueryManager and will be placed into the QueryBatcher’s queue. I'll close the issue. First ideas of API would be something like this: In the above example I've hardcoded it which is achievable with a static number of hooks, however if numPreloadedPages becomes dynamic it's not possible as per my understanding. It introduces http request batching automatically globally for queries that run "at the same time" within a certain timeout window. Primarily, if you’re trying to debug stuff from the server’s point of view, you’ll see queries that look very different from what you initially fired on the client, which could make it harder to debug your queries. Multipart requests specification for GraphQL. In fact, GraphQL queries can simply be made with cURL requests in the Terminal if one chooses to do so, with both GET and POST requests supported. With that intro, lets understand how the solution is … This is why we have smart client implementations, such as Apollo Client and Relay, that take advantage of GraphQL’s query structure to do useful things. So, as long as the two queries above are fired within the same 10-millisecond tick of the batcher, they’ll be sent as one request, like so: Notice that your application code can remain completely oblivious to this batching. Oh, and no junk mail. To turn it on, all you have to do is set the shouldBatch option in the constructor: And that’s it! I have a simple solution that worked for me. Now the two queries above will be sent in one request. It does this by using a pretty simple concept called query merging. Also, to be fair, your example is not that great, why can't you run a single query to get all your pages? In this tutorial, I will show you the basics of how to use GraphQL with React and TypeScript. and I don't understand how can it be messier than have multiple useQuery hooks that'd end up use renaming like. Motivation for this post. For example, say you have two UI components that each fire off a couple of GraphQL queries with Apollo Client: Batching is turned off in Apollo Client by default. @asotog you want to use the apollo link batch http https://www.apollographql.com/docs/link/links/batch-http/.

apollo graphql multiple queries in one request

apollo graphql multiple queries in one request

What is GraphQL Schema? One potential solution is described by Lee Byron, one of the creators of GraphQL, in his talk about new GraphQL features: batching at the network transport level. Free to use (forever). With REST API, you may need to make multiple request to get all the data. Second, you can get multiple data from different sources in just one single query. For example, given the following query: The server will return a result that looks like the following: Using this feature of GraphQL, we can step through the AST of a query and rename all of the top-level fields, inline fragments and named fragments in a way that makes sure that they will never conflict once merged. if you want to learn how to use the expression "to be fair" correctly this is a good start https://www.collinsdictionary.com/us/dictionary/english/to-be-fair. We use a query to fetch data from the server/database. Batching works only with server that support batched queries (for example graphql-server). When queries are sent in one request, you can use. You don’t need anything fancy to load some data from a GraphQL server. Graphql request getting cancelled in the first time and then giving a successful response with the same query parameter. Declarative data selection. This style of query merging can work with any GraphQL server since it only uses what is available in the GraphQL specification. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. So, we turn to a nice feature of GraphQL: aliasing. It's not needed, you can use skip to get what you want. Am I missing something or are you really saying that is an ideal API? Apollo Client is a convenient client library for working with GraphQL. https://www.apollographql.com/docs/react/react-apollo-migration#compose-to-render-composition. https://www.apollographql.com/docs/react/v3.0-beta/data/fragments/. Try Studio . apollo-client is a generic framework-agnostic package for performing and caching GraphQL requests. @asotog I still think the batch-http link might help you more than you think. I am not able to understand the reason to cancelling the request. @githubjosh I would disagree with assessment in that article which. I don't see how that's related and if you read the code I posted I am using the skip option. maybe some cleanup did not happen and apollo still considers the query running? I'm fairly sure about that but please correct me if that's not the case. By clicking “Sign up for GitHub”, you agree to our terms of service and P.S. https://graphql.org/learn/queries/#fragments privacy statement. To my understanding, the way apollo resolves queries from the cache is by looking up that query from the cache given the exact same operationName + variables. For example, if user visits page 1, we preload page 2 and 3 after the. You should just change the limit accordingly ‍♂. Yeah you could write 100 useQuery into a component and skip them dynamically. So, we need to utilize a method that can turn multiple queries into a single query, submit it to the server, receive a single result and then unpack it into results for each of the queries initially submitted. The second technique is using multipart form requests. Save time and build faster with features like one-click query building, intelligent search, and variable extraction. later i want to run the query again.. Actual outcome: i can cancel the query using an AbortController.but, if i execute the query again, no http-request is sent. Want to try this out? i want to cancel a running graphql query using the AbortController approach to stop the fetch request. thanks in advance. Apollo Studio Explorer is the GraphQL IDE of the future. We also rename variables since two queries can definitely refer to a variable that takes on different values in each query (e.g. is there any configuration i'm missing ? As a simple example, say we’re telling the BatchedNetworkInterface to batch these two queries: Then, we can imagine a simple approach to merging that produces the following query: However, the devil is in the details. If so, that feels like an unnecessary restriction. You signed in with another tab or window. Free to use (forever). In GraphQL, fields at each "level" of the request are executed and resolved in parallel. We’ll occasionally send you account related emails. Was this post helpful? I think the Apollo API is great by the way! Not all server implementations support this, one of them that supports it is Apollo. All GraphQL servers expose a way for us to submit a single query and receive a single result in return. This article also assumes that you've already set up Apollo Client and have wrapped your React app in an ApolloProvider component. a variable like id). Third, it uses a type system to describe what data can clients request. However, this is much better, since the queries you see on the server will look exactly as they do on the client. In your example, user and SomeOtherStuff are both fields of the same type (the root Query type) -- so they will be resolved at the same time. Multiple GraphQL Operations in a Request GraphQL requests can contain one or more operations. As a reminder, GraphQL is a popular alternative to REST APIs. Note that quering two objects at the same time will affect caching behavior. @ivan-kleshnin @TSMMark sorry i'm new to apollo and graphql in general I have something like this: each of these hooks using useQuery with different queries each, but i see in the network log, 2 requests going to the graphql separate, so my question was if there is any way apollo handles the 2 request at the same time, or i need to put the 2 gql queries in same useQuery, what approach you would take in my case ? Have a question about this project? The important bit here isn’t actually the QueryBatcher: that just acts as a consumer on a queue. Sorry maybe I'm not explaining the problem well enough. GraphQL layer lives between the client and one or more data sources, re c eiving client requests and fetching the necessary data according to your instructions. Apollo Server’s Readme had a comparison with express-graphql at some point, which can help understand the differences. Intended outcome: I am trying to use the link object on an ApolloClient instance to execute a query that is part of a document that contains multiple queries. All you need for a basic client is a POST request that sends a query down to the server and gets a result back. In our situation, we are paginating a table and preloading a variable number of next pages. This installment of the series will look at the first step of analyzing how well GraphQL is protected, specifically securing the GraphQL schema by disabling introspection query which is enabled by default. In our product, there is the a page which needs data from 2 or 3 GraphQL queries and we want to call multiple queries with one useQuery(). This may help you achieve separation of data concerns, where your component still has defined colocated data dependencies, but you are merging the queries at a higher level to optimize HTTP traffic. The query batcher operates on “ticks” — it checks a queue every 10 milliseconds to see if there are any pending queries. GraphQL queries can be made with fetch() requests alone — no additional middleware or specialised packages are required to use GraphQL. updating the UI for Meteor Galaxy to use Apollo Client, When To Use Refetch Queries in Apollo Client. We’ve picked nice, non-conflicting names in our two example queries, but we have no guarantee of that being the case when we are attempting to merge arbitrary queries. Check out the docs for a slightly closer look at the semantics of batching and how you can use it with custom network interface implementations. The only other alternative to Apollo Server was Express GraphQL, but Apollo Server has a lot of convenience features that I preferred over Express GraphQL. I'll also note that you can have individual queries opt out of batching, if needed. Then, once transport-level batching is built into most GraphQL servers, you’ll be able to reap these benefits while still getting nice-looking queries in your server logs. Is it expected that only one network request can be in flight at any given time from useQuery? In the last post, we touched on the topic of GraphQL security. Why can't you use the existing "skip" option to conditionally run the queries? Operations are one of query, mutation, or subscription. A single article can not encapsulate all the things one wants to know about such an interesting technology. GraphQL Helix did not seem to have a lot of community support. First, you'll explore what GraphQL is and how to define your resources with a schema. Intended outcome: i use react with apollo. In my previous post GraphQL Persisted Queries Using GET Requests we built a GraphQL server that used middleware to pattern match against a static extracted queries file. apollo-cache-inmemory is ... Find more details about how Apollo caching works here. In our product, there is the a page which needs data from 2 or 3 GraphQL queries and we want to call multiple queries with one useQuery(). Have suggestions? Sure. The GraphQL API can handle this type of complex relational query … Rather, it is the implementation of a BatchedNetworkInterface that batches together multiple requests in a way that works with any spec-compliant GraphQL server. All the code inspired in this blog post is from a GitHub issue thread (Read more for interesting discussion …. REST API routes usually are handled by one route handler. In this course, Building a GraphQL API with Apollo Server, you'll learn to build APIs that return multiple resources over one call, and give the client control over what data is returned. The top level of my app is wrapped in an . Smart GraphQL clients can make interaction with the server more efficient by reducing the number of roundtrips to fetch data. So the "default" approach should probably be the one with a single useQuery and multiple query objects, not the one with multiple useQuery. Each query response is put into the cache (the corresponding request is used to generate the cache key). But there is definitely benefit with being able to declare the needs in a single query and to support the full extent of what a GraphQL document is. Queries: For those coming from the REST background, a query in GraphQL is like a GET request to a route or an endpoint. You're still talking about a static number of useQuery. However if you insist not using batch-http apollo link, you should follow @ivan-kleshnin's advice. A client-side schema gives a great “starting point” should you eventually decide to take the plunge and invest in a real GraphQL server. When we apply this query merging to the queries we just mentioned, we get the following composed query: This query is then sent down to the server and we get a result that looks like this: This does look a bit ugly, but your frontend code will never see any of this. Similar posts. Become an Apollo insider and get first access to new features, best practices, and community events. For example, one if the two queries is marking a variable as required and the second query doesn’t mark it as required, an error will be thrown in this case as the definitions are not matching. Consider .css-147bmoc{color:#7156d9;-webkit-text-decoration:none;text-decoration:none;border:none;background:none;cursor:pointer;padding:0;}.css-147bmoc:hover{-webkit-text-decoration:underline;text-decoration:underline;}leaving feedback so we can improve it for future readers ✨. Transport-level batching is easier to debug than query merging, but it requires additional server support. We wanted ensure that an application developer using Apollo Client wouldn’t have to do anything extra to get batching to happen; you should get it “for free”. We’ll also consider some next steps we can take to make batching even more awesome in GraphQL. If there are multiple queries in the queue, they are combined into one server request. I'd use the second only when it's really necessary. This will ensure my passed in "service" string ends up on the request header sent to the server. There are some downsides to this approach though. If a request only has one operation, then it can be unnamed like the following: Ever. I have two components in the tree that each call useQuery with distinct queries against completely different parts of the schema. https://www.collinsdictionary.com/us/dictionary/english/to-be-fair, https://www.apollographql.com/docs/link/links/batch-http/, https://graphql.org/learn/queries/#fragments, https://www.apollographql.com/docs/react/v3.0-beta/data/fragments/, How to run multiple queries at once using GraphQL and Apollo Client. Once the results for both of the queries have returned from the server, the QueryBatcher will resolve the promises issued for both of the queries. This is similar to how Relay works — Each component may "export" a query Fragment, then a parent component that actually makes the query is responsible for merging the query fragments into one complete query, and to make the actual query to the server. I understand and we'll call useQuery as described :) Because using GraphQL and especially Apollo client suite is so convenient, one would like to develop frontend apps in GraphQL. That's my point. Sign in Do not complain in endless discussions about adding GraphQL … It involves taking multiple queries and putting them all under a single root query. Something that worked for me was using another component : If it's helpful to anyone, here's a great resource with several approaches How to run multiple queries at once using GraphQL and Apollo Client. This way, all of the data can be loaded in one roundtrip, without any extra effort. We prefer to work with Apollo, as it has a large community of supporters, is frequently updated, and is compatible with iOS, Android, Angular, Ember, Vue, and React. The component which renders last seems to cancel the in flight /graphql request created by the first component's useQuery call. This is a feature that allows you to upload files via GraphQL mutations directly. You can wri… mm had same question i have 2 use queries in the same component fetching with different queries, but i see 2 http requests, is it possible to only make 1 request ? The first useful feature of useResult is picking one object from the result data. Although query merging is very effective, it has a few downsides. Another important improvement of GraphQL is that multiple operations can be sent and retrieved using a single endpoint (usually /graphql) and a single network request. Link: https://www.howtographql.com/basics/2-core-conc… The GraphQL schema can more easily be built incrementally based on the requirements of the frontend, rather than trying to convert your entire REST API into a GraphQL-based solution in one go. Hi, In advance thank you great library. The server has to know how to process an array of queries and respond with an array of results. Since we’re re-using the same variables in both components, if the two queries don’t accept the same variables (or their type definitions), we can’t have multiple definitions for them. In this post, we’ll first take a look at how we can use batching and then we’ll open up the box and see how it is implemented. But it turns out that caching isn’t the only thing that can make server communication more efficient. Apollo Client queries are standard GraphQL, so any query that runs in GraphiQL will also run when provided to useQuery. Because react does not allow you to have a variable number of hooks, I still think there is a usecase for ONE hook that performs multiple queries. What you want to do is compose multiple useQuery into your own custom hook: Thank you for your quick response. Next, you'll discover how to resolve queries and nest objects. Instead, imagine we submitted a request that looked like this: And the server would return a response that looks like: This is another way of accomplishing what we are currently doing with query merging: fetching the results for multiple queries in a single roundtrip. Is it possible to do the same things as compose() method defined in react-apollo? Or should we call useQuery with each queries? It becomes messy easily when it grows and difficult to pass the data around. Here's one approach (from the article above): Another simple solution I found useful is to wait on destructuring the results until you can control the name you give each value. This is something that is definitely and added bonus. While updating the UI for Meteor Galaxy to use Apollo Client, we realized how desirable it is to have query batching in a production app. Powerful local GraphQL development. So if you have previously queried { offset: 0, limit: 100 }, and now are querying the same operation with variables { offset: 0, limit: 10 }, the cache will be missed and the network will be hit. Check out Apollo Client. Those policies can be, for example: My code above (single useQuery, multiple queried objects) will result in a single HTTP request. I am using Apollo client + Graphql + React in my project and I am facing a weird issue in Graphql requests. But I will add to it: you might want to consider breaking your one query (comprised of the two smaller queries) into logical query Fragments (see links below). A common way to reduce server roundtrips is through caching, because the fastest way to load something is to already have it. Save time and build faster with features like one-click query building, intelligent search, and variable extraction. This means that if you render several components, for example a navbar, sidebar, and content, and each of those do their own GraphQL query, they will all be sent in one roundtrip. Apollo lets you automatically batch multiple queries into one request when they are made within a certain interval. I am simply renaming the fields useQuery is giving me in the first call, so that they can live in the same scope, otherwise the second query will overwrite the first. There are a lot of libraries you can use to work with GraphQL, including Relay, Prisma, URQL, and Apollo Client. Now, on the server, using express, I set up a redirect route that reads the header and sends the request on to either one or the other endpoint based on this header: graphQLServer. In the meantime, just passing an additional option to the Apollo Client constructor will let you load your UI in a single roundtrip rather than a dozen, without needing to put in any effort to manually merge queries using fragments. Apollo Studio Explorer is the GraphQL IDE of the future. Both of the queries will go through the QueryManager and will be placed into the QueryBatcher’s queue. I'll close the issue. First ideas of API would be something like this: In the above example I've hardcoded it which is achievable with a static number of hooks, however if numPreloadedPages becomes dynamic it's not possible as per my understanding. It introduces http request batching automatically globally for queries that run "at the same time" within a certain timeout window. Primarily, if you’re trying to debug stuff from the server’s point of view, you’ll see queries that look very different from what you initially fired on the client, which could make it harder to debug your queries. Multipart requests specification for GraphQL. In fact, GraphQL queries can simply be made with cURL requests in the Terminal if one chooses to do so, with both GET and POST requests supported. With that intro, lets understand how the solution is … This is why we have smart client implementations, such as Apollo Client and Relay, that take advantage of GraphQL’s query structure to do useful things. So, as long as the two queries above are fired within the same 10-millisecond tick of the batcher, they’ll be sent as one request, like so: Notice that your application code can remain completely oblivious to this batching. Oh, and no junk mail. To turn it on, all you have to do is set the shouldBatch option in the constructor: And that’s it! I have a simple solution that worked for me. Now the two queries above will be sent in one request. It does this by using a pretty simple concept called query merging. Also, to be fair, your example is not that great, why can't you run a single query to get all your pages? In this tutorial, I will show you the basics of how to use GraphQL with React and TypeScript. and I don't understand how can it be messier than have multiple useQuery hooks that'd end up use renaming like. Motivation for this post. For example, say you have two UI components that each fire off a couple of GraphQL queries with Apollo Client: Batching is turned off in Apollo Client by default. @asotog you want to use the apollo link batch http https://www.apollographql.com/docs/link/links/batch-http/.
