Linters for RxJS 7 deprecations

[timdeschryver]

Feature Request

Is your feature request related to a problem? Please describe.

The RxJS 7 release includes a couple of deprecations, these were also highlighted in Ben's talk at ngconf.

Describe the solution you'd like

It would be useful to have linters that fix these for us, just like with the previous release.

Describe alternatives you've considered

Additional context

I'm not sure if someone is already working on this, but I started here with an implementation.

Currently, it covers the basics for:

• result selectors
• subscribe signature
• tab signature
• the deprecation of operators to operatorWith

This is just me trying to implement the linters, but I thought it could be of help, as a starting point.
It uses eslint and @typescript-eslint/parser under the hood.

Feel free to close this, or ping me if you need more information.
I also want to offer my help if we want to move forward with this and cover more cases.

The easiest way to run it is with the following command but be aware it will install eslint and @typescript-eslint/parser if needed.

npx eslint-plugin-rxjs-fixers-poc

I recently discovered ts-morph... and I used these deprecations as a POC to get familiar with ts-morph.

See rxjs-fixers-morph for the implementation to provide fixers for the RxJS 7 deprecations.
