Inspector

The repository includes the ESLint config inspector so you can see the final merged config instead of guessing which layer is responsible for a rule.

Run It

bash

npm run inspector

Confirming whether a rule comes from the core package, a framework package, or an optional integration.
Verifying the order of config layers.
Debugging conflicts between TypeScript, framework packages, and formatting tools.
Understanding what strict: true or a preset changed in the final output.

Start with the inspector when the final rule value is surprising.
Compare the result with the docs page for the relevant framework or optional integration.
Use playgrounds to reproduce the issue in a real project shape.
