Core Components of Apollo Dev Tools

Apollo Dev Tools include several important parts that help you work better when building apps with Apollo and GraphQL. These main parts help with things like managing your app's schema, making queries, finding and fixing bugs, and automatically creating code.

Apollo Graph Manager

Apollo Graph Manager is a tool in the cloud that helps keep track of your app's schema as it changes. It's like a central place where you can see and manage your schema. Here's what it does:

• Schema registry - Keeps a history of your schema changes. This helps everyone stay on the same page and avoids problems.
• Explorer IDE - A tool that lets you visually play with your schema. You can try out queries and check out the docs without writing code.
• Access control - Lets you decide who can do what with your schema. This means you can keep important parts safe.
• Organization management - You can add people to your team and control what they can do with the schema.

By putting everything about your schema in one place, Graph Manager makes it easier for teams to work together.

Apollo Client Devtools

This is a tool you add to your browser that makes working with Apollo easier. It includes:

• GraphiQL console - Lets you send queries right from your browser. It's a quick way to check things without leaving your web page.
• Watched query inspector - Shows you the queries that are running and what they're bringing back. It helps you understand what's happening in your app.
• Cache inspector - Helps you see and search the data stored in your app's cache. This is useful for understanding and fixing how your app stores data.

These tools make it simple to find and fix issues, understand how your app works, and improve how it uses data, all from your browser.

Apollo Codegen

Apollo Codegen is a tool that automatically creates code from your GraphQL schema and queries. This means less manual coding for you. Here's what it offers:

• Supported languages - It can create code for many programming languages, making it flexible for different projects.
• Flexible output - You can customize what it generates, from CLI tools to React hooks.
• Incremental generation - It only updates the parts that need it, based on changes to your schema.

Together with Graph Manager and Client Devtools, these Apollo Dev Tools provide a full set of tools that make building and working with GraphQL applications a lot smoother. You get tools for quickly fixing queries in your browser and automatic code generation that keeps everything up-to-date.

• Set up Codegen to automatically create things like typed interfaces and React hooks based on your project's structure. This saves you time and helps avoid mistakes.
• Try out changes with Explorer IDE in Graph Manager before making them official. This lets your team test things out and gives you confidence in your changes.
• Get familiar with how caching works. Understanding this helps you use the Cache Inspector better, which can help you figure out and fix data issues.
• Look at network requests in Client Devtools to spot slow parts of your app. Find out which queries are taking too long, make adjustments, and see the difference.
• Save queries you use a lot in GraphiQL. This way, you can quickly check changes without having to rewrite them each time.

Common Use Cases

Here are some everyday problems Apollo Dev Tools can help you solve:

If your app's data isn't storing correctly - Use the Cache Inspector to see how your data is organized and find out what's wrong.

When adding new features to your schema - Test your ideas in Explorer IDE first. This helps you see how they'll work before making them live.

If you're working on React components - Client Devtools lets you see which queries your components are using. This makes it easier to understand and test them.

If data seems to be missing - Check in Explorer IDE to make sure your queries are asking for everything they need from your schema.

If your app loads slowly at first - Use Client Devtools to check why. It could be because of missing cached data or slow network requests.

To fix bugs - Use the history in Graph Manager's Explorer IDE to repeat the exact steps that caused a bug. This makes it easier to figure out the problem and share it with your team.

By getting to know Apollo Dev Tools, you can tackle many common issues in developing GraphQL apps through smart debugging and making your app run better.
