Apollo Devtools are a game-changer for developers, allowing them to catch errors in real-time and debug their applications more efficiently.
With Apollo Devtools, you can see the entire data flow of your application, from the server to the client, and even down to the individual components. This level of visibility is invaluable for identifying and fixing issues quickly.
One of the key features of Apollo Devtools is the ability to catch errors in real-time, which saves developers a significant amount of time and frustration.
Apollo Graph Manager
Apollo Graph Manager is a cloud service that helps you manage, validate, and secure your organization's data graph.
It provides a GraphQL schema registry that tracks changes and variants, a schema explorer that makes it easy to inspect your schema's queries, mutations, and other object definitions, and team collaboration via organizations.
All Apollo users get these features for free, making it a valuable tool for anyone working with GraphQL.
Advanced features are available with a subscription to an Apollo Team or Enterprise plan.
To get started with Graph Manager, check out the overview to learn more about its capabilities.
Client Devtools
The Apollo Client Devtools are available as extensions for Chrome and Firefox, and they appear as an "Apollo" tab in your web browser inspector. You can also manually attach your Apollo Client instance to the global window object to enable the devtools.
To enable the devtools in production, you can pass `connectToDevTools: true` to the ApolloClient constructor in your application. Alternatively, you can manually attach your Apollo Client instance to the global window object.
The devtools currently have four main features: Explorer, Watched query inspector, Mutation inspector, and Cache inspector. These features allow you to make queries against your GraphQL server, view active queries and variables, and visualize the Apollo Client cache.
Client Devtools
The Apollo Client Devtools are a game-changer for anyone working with GraphQL. They're available as an extension for Chrome and Firefox, and they appear as an "Apollo" tab in your web browser inspector.
To use the devtools, you'll need to pass `connectToDevTools: true` to the `ApolloClient` constructor in your application. This will enable the devtools for your app, even in production.
The devtools have several main features, including the Explorer, Watched query inspector, Mutation inspector, and Cache inspector. These features allow you to view active queries, variables, cached results, and re-run individual queries, as well as visualize the Apollo Client cache and search through it by field names and/or values.
Here are the main features of the devtools:
- Explorer: A built-in version of the Apollo Studio Explorer that allows you to make queries against your GraphQL server using your app's network interface directly.
- Watched query inspector: View active queries, variables, cached results, and re-run individual queries.
- Mutation inspector: View fired mutations, variables, and re-run individual mutations.
- Cache inspector: Visualize the Apollo Client cache and search through it by field names and/or values.
To enable the devtools in production, you can manually attach your Apollo Client instance to `window.__APOLLO_CLIENT__` or pass `connectToDevTools: true` to the constructor. This will allow you to use the devtools even when your app is in production mode.
Generate
The "Generate" command is a powerful tool for client developers. It generates types for query and mutation operations made against the schema.
This command is specifically designed to generate Swift code by default from a set of query definitions in .graphql files.
You can also use it to generate type annotations for other programming languages, such as TypeScript, Flow, or Scala, by using the --target option.
The generated code will help you get started with your client development project, but keep in mind that it won't generate types for the schema itself.
Development Tools
Apollo Devtools offer a range of development tools to streamline your workflow.
Apollo Client's cache is automatically refetched when the cache is invalidated. This means you can easily manage data fetching and caching in your application.
Using Apollo Devtools, you can easily identify and fix issues related to data fetching and caching.
Apollo Devtools allow you to inspect and manipulate the cache, making it easier to debug and optimize your application's performance.
Apollo Client's cache is automatically updated when the cache is invalidated, ensuring that your application always has the most up-to-date data.
Extensions
The Apollo Chrome extension is a must-have for anyone working with GraphQL, it adds an additional tab to your Dev Tools.
This extension provides an interactive interface that's similar to the GraphiQL editor, making it easy to explore and use available queries and mutations.
The Build button opens up a sidebar with all the available queries and mutations you can use, it's a great way to see how your queries will execute.
The extension uses the current user session, allowing you to see how queries execute with the current user's permissions, which is a huge time-saver.
The downside is that the extension only works with the Apollo GraphQL client.
