Angular13 with rxjs 7.4 and TS 4+ gives error....Could not find a declaration file for module 'rxjs'

Question

I am starting a new Angular app with V13 and rxjs7.4 which is giving me the above error on:

import { BehaviorSubject } from 'rxjs';

At first I followed the suggestion to create a typings.d.ts declaration but though the error went away another error appeared...on further research I found this comment relating to V12:

*zijianhuang commented on May 17

Angular 12 with rxjs 7.0.1 could be built and run, however, the VS IDE could not check reference. And tsconfig with strict=true has NG CLI complaining no reference to rxjs could be found and suggesting downloading type info.*

So I set strict-false in my tsconfig and now my rxjs error is gone. The question I have is this is obviously a temp solution. Is there a permanent fix to this?

Answer 1

The correct way of resolving this issue is using @types from npm. The command is as follows:

npm install @types/rx --save-dev

For more information, see npm.
