Codacy ESLint

Adding new plugins / configs

Install the package using npm:
```
npm install <package-name>
```
[Plugins only] Add the plugin to the plugins section in the file src/eslintDefaultOptions.ts only if it's stated in the plugin's documentation
[Plugins only] If the plugin has descriptions for rules on GitHub, reference them at src/docGeneratorMain.ts to include them on the generated documentation. To do this, add a section similar to the following example:
```
console.log("Generate xss description files")
await docGenerator.downloadDocs(
  (pattern) =>
    `${githubBaseUrl}/Rantanen/eslint-plugin-xss/master/docs/rules/${pattern}.md`,
  "xss"
)
```
Generate documentation so it adds the new plugin documentation

Generating documentation

npm install
npm run generateDocs

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 FROM node:$NODE_IMAGE_VERSION to 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.
