Disallow importing operators from rxjs/operators (rxjs-x/prefer-root-operators)
April 18, 2025 · View on GitHub
💼 This rule is enabled in the following configs: ✅ recommended, 🔒 strict.
🔧💡 This rule is automatically fixable by the --fix CLI option and manually fixable by editor suggestions.
This rule prevents importing from the rxjs/operators export site.
Most operators were moved to the rxjs export site in RxJS v7.2.0
(excepting a few old and deprecated operators).
The rxjs/operators export site has since been deprecated and will be removed in a future major version.
Note that because a few operators were renamed or not migrated to the rxjs export site,
this rule may not provide an automatic fixer if renaming the import path is not guaranteed to be safe.
See the documentation linked below.

When Not To Use It

Type checked lint rules are more powerful than traditional lint rules, but also require configuring type checked linting.
