The comparison between "rxjs-tslint" and "rxjs-tslint-rules" npm packages

Previously, I utilized the rxjs-tslint-rules package to identify RxJS-related issues in my projects. This package was included in the devDependencies section of my projects' package.json files.

Now, there is a new rxjs-tslint package that introduces additional rules tailored to RxJS 6 and includes the rxjs-5-to-6-migrate tool.

After migrating, if I wish to continue using the following:

  • rxjs-collapse-imports
  • rxjs-pipeable-operators-only
  • rxjs-no-static-observable-methods
  • rxjs-proper-imports

rules with TSLint, do I need to manually add them to my tslint.json file and include the rxjs-tslint package in the devDependencies? Or is the rxjs-tslint package intended as a one-time migration aid with rules already covered by the comprehensive rxjs-tslint-rules package?

Answer №1

Currently, the purpose of rxjs-tslint is to serve as a tool for migrating RxJS v5 codebases to v6. When you install it, scripts are placed in node_modules/.bin to assist with this transition.

However, you have the option to also install rxjs-tslint as a devDependency. In this case, you would need to reference it in your tslint.json file along with rxjs-tslint-rules, like so:

{
  "extends": [
    "rxjs-tslint",
    "rxjs-tslint-rules"
  ],
  "rules": {
  }
}

Similar to rxjs-tslint-rules, rxjs-tslint remains neutral and does not have any default rules enabled. To activate the rules mentioned in your query, you must configure them within the rules section of the file.

As the creator of rxjs-tslint-rules, I have collaborated with the developers of rxjs-tslint. It is possible that in the near future, some rules from my package will be integrated into rxjs-tslint to align with best practices. Until then, and potentially beyond, you can utilize rules from both packages interchangeably.
