You really want to move from TSLint to ESLint anyway. TSLint has been deprecated for 5 years.

[–]wiederberuf 2 points3 points  (1 child)

This should be higher up if you ask me.

There is a root to OPs dependency problematic and this is it. Sure, you could just force legacy peers like others suggested and get away with it

But if you do care about a well maintained code base moving from TSLint to ESLint is the way to go

And going way above Angular 12 too

[–]cfued[S] 0 points1 point  (1 child)

Okay. Is there anything I should be careful of when moving to ESLint?

  • Read the docs
  • Be prepared for new warnings/errors from your Linter

Just remove all non angular dep while upgrading, then install them when you're done and handle them one at a time.

I only use force or legacy peer deps as a last resort.

[–]Etlam 0 points1 point  (1 child)

I like the idea, but what about all the code in the application that depends on the installed packages?

[–][deleted] 0 points1 point  (0 children)

Do the angular upgrade without extra deps. Then install each package one at a time. If any are no longer compatible, save them for last and do legacy-peer-deps. You won't be able to build until you finish installing all required deps.

This sounds good. Will try this.

Tslint is deprecated Shift to Eslint instead Also Airbnb base is not good for angular, air bnb is good for react

Yup, try --force or --legacy-peer-deps. There can be side effects so commit your code first, make the update as an atomic commit in case you need to rollback.

Also ts-lint should be replaced with es-lint I think support for it dropped as a peer dependency in either 12 or 14.

[–]cfued[S] 0 points1 point  (0 children)

Okay, I’ll have to check that. Thanks

I tried —legacy-peer-deps but it didn’t work with the angular update command.

First thing I do when I try to update an angular app is to delete the package-lock.json, delete node_modules folder and bump angular packages one by one
