Codacy ESLint

Manually upgrading packages / plugins / configs

npm run upgrade

Adding new packages / plugins / configs

Install the package / plugin using npm:

npm install --legacy-peer-deps --omit=dev package-name

Configuring new plugins

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

If the plugin has descriptions for rules on GitHub, reference them at src/docGeneratorMain.ts to include them on the generated documentation.

Add a section similar to the following example:

await docGenerator.downloadDocs(
  // plugin prefix (e.g., xss/some-pattern-id)
  "eslint-plugin-xss",
  // path to .md patterns files within github
  `/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"
  "v",
  // change to true if it should fail in case of missing .md files for any pattern
  // (default) false
  false
)

In src/eslintPlugins.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",
  //(...)
]

Generate documentation so it adds the new plugin documentation.
```
npm run build:docs
```
Add a new test in /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 run build:docs

Test changes to codacy-seed locally

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

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
Copy the codacy-seed-0.0.1.tgz into the root of this repository
Install the package: npm install codacy-seed-0.0.1.tgz
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 ./
- Remove multi-stage docker steps
  - Lines from the beginning of the file until RUN rm -rf /package.json /package-lock.json
  This way you skip copying the files to the other docker, and another npm install
Publish your docker locally as normal: docker build -t codacy-eslint:local .

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.
