Fragment Usage and Validation

Common Mistakes and Troubleshooting

Configuration Issues

Problem: Extension not providing autocomplete or validation Solution: Ensure your apollo.config.js is properly configured and your GraphQL server is running.

Schema Loading Problems

Problem: Schema cannot be loaded from endpoint Solution: Check network connectivity and CORS settings on your GraphQL server. You can also use schema introspection files:

Performance Optimization Tips

1. Use .graphql files for complex queries to improve parsing performance
2. Configure excludes properly to avoid scanning unnecessary directories
3. Enable/disable features based on your needs in VSCode settings
4. Use workspace trust for better security with unknown repositories

Frequently Asked Questions

How do I resolve "Cannot query field" errors?

These errors typically indicate a schema mismatch. Ensure your local schema is up to date by restarting the Apollo language server or reloading VSCode. You can also try regenerating your schema file if using a local schema.

Can I use the Apollo IDE plugin with multiple GraphQL endpoints?

Yes, you can configure multiple services in your Apollo configuration. Use service name prefixes in your operations or configure different projects for different parts of your codebase.

Why is autocomplete not working in my .graphql files?

Ensure you have the Apollo GraphQL extension installed and your configuration file is properly set up. Also, check that your GraphQL server is running and accessible from your development environment.

Conclusion

The Apollo IDE plugin for VSCode is an indispensable tool for modern GraphQL development. By providing intelligent autocomplete, real-time validation, and seamless schema exploration, it significantly improves developer productivity and code quality. Whether you're working on a small project or a large enterprise application, integrating this plugin into your workflow will help you build more reliable and maintainable GraphQL applications.
