Codacy ESLint 9

Codacy Badge CircleCI

Manually upgrading packages / plugins / configs

npm run upgrade

Adding new packages / plugins / configs

Install the package / plugin using npm:

npm install package-name -w codacy

Configuring new plugins

NOTE: Before adding a plugin to the Codacy UI, make sure it has widespread use and is actively maintained.

  1. If the plugin has descriptions for rules on GitHub, reference them at workspaces/doc-generator/src/index.ts to include them on the generated documentation.

    • Add another element to the array downloadDocs similar to the following example:

      {
        // plugin package-name
        packageName: "eslint-plugin-xss",
        // path to .md patterns files within github
        relativeUrl: `/Rantanen/eslint-plugin-xss/master/docs/rules/`,
        // prefix for tag relases (for example if tags are "v.1.0.0" you have to prefix tags with "v.")
        // or "false" if package has no tags released
        // (default) "v"
        versionPrefix: "v",
        // change to true if it should fail in case of missing .md files for any pattern
        // (default) false
        rejectOnError: false
      }
    • In lib/models/plugins.ts add a new value to the array with the name of the package/plugin:

      // make sure it matches the correct name of the package
      const packageNames = [
        //(...)
        "@angular-eslint/eslint-plugin",
        //(...)
        "eslint-plugin-xss",
        //(...)
      ]
  2. Generate documentation so it adds the new plugin documentation.

  3. Add a new test in workspaces/doc-generator/docs/multiple-tests that uses the newly added plugin. You can use the Getting Started section of the package documentation to find a small usage example.

Generating documentation

npm start -w docs-generator

Test changes to codacy-seed locally

You may need to test changes that comes from our codacy-engine-typescript-seed.

  1. Create a package with your changes on the seed:

    • Don't forget to update the dependencies: npm install
    • Compile the library: npm run compile
    • Package the library: npm pack

    This should generate a codacy-seed-0.0.1.tgz on your codacy-seed repository

  2. Copy the codacy-seed-0.0.1.tgz into the root of this repository

  3. Install the package: npm install codacy-seed-0.0.1.tgz

  4. Update Dockerfile and .dockerignore so you copy the codacy-seed-0.0.1.tgz inside the docker you will be building

    • Add !codacy-seed-0.0.1.tgz to your .dockerignore
    • Add the package to the docker before RUN npm install: COPY codacy-seed-0.0.1.tgz ./
  5. Publish your docker locally as normal: npm run build:docker:dev

Limitations

Incompatible rules

There are some ESLint rules that will be ignored when running this Docker container. For more details on the ignored rules, check blacklistRegexes defined at blacklist.ts.

Usually, these rules need an Internet connection and/or to check node_modules, and would not run successfully on our Docker container environment.
