      • Compilation diagnostic rules

      Build diagnostics complement static lint tools such as ESLint. They run against Rspack's build data and can use information such as the ModuleGraph, per-module metadata, and generated runtime code.

      During the build process, if issues are discovered, they will be visible in the CLI and the final diagnostic summary webpage, as shown below:

      How to use

      Currently, Rsdoctor provides built-in rules and custom rules.

      Built-in Rules

      The existing diagnostic tool includes multiple rules, all of which are enabled by default. They are:

      1. [E1001] Duplicate Packages
      2. [E1002] Cross Chunks Package
      3. [E1003] Loader Performance Optimization
      4. [E1004] ECMA Version Check
      5. [E1005] Default Import Check

      For specific details, refer to Built-in Rules.

      Custom rules

      Rsdoctor also collects analyzed data and allows users to integrate custom rules through the Linter API. For details on custom rules, refer to Custom Rules.
