eslint-plugin-rxjs

library5.0.3jsnpmunverified

ESLint plugin providing a comprehensive set of rules for RxJS (v5, 2024). It reimplements the rules from rxjs-tslint-rules for ESLint, covering common mistakes like async subscribe, ignored observables, nested subscribes, and more. Almost all rules require @typescript-eslint/parser and a TypeScript project. The package includes a recommended configuration with opinionated rules separate. Release cadence is stable with frequent updates. Compared to alternatives like eslint-plugin-rxjs-angular (Angular-specific), this plugin covers generic RxJS patterns across frameworks.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

plugin

✓ plugins: ['rxjs']

✗ plugins: ['eslint-plugin-rxjs']

Use shorthand 'rxjs' in ESLint config; the full name is not needed.

recommended config

✓ extends: ['plugin:rxjs/recommended']

✗ extends: ['eslint:recommended']

Only the plugin's recommended config enables its rules.

rules

✓ rules: { 'rxjs/no-async-subscribe': 'error' }

✗ rules: { 'rxjs/no-async-subscribe': 2 }

Rule names are prefixed with 'rxjs/' and values use string 'error' not numeric 2.

Setup ESLint with rxjs plugin, using @typescript-eslint/parser and recommended config.

// In .eslintrc.js const { join } = require('path'); module.exports = { parser: '@typescript-eslint/parser', parserOptions: { ecmaVersion: 2019, project: join(__dirname, './tsconfig.json'), sourceType: 'module', }, plugins: ['rxjs'], extends: ['plugin:rxjs/recommended'], rules: { 'rxjs/no-async-subscribe': 'error', 'rxjs/no-ignored-observable': 'error', 'rxjs/no-ignored-subscription': 'error', 'rxjs/no-nested-subscribe': 'error', }, };
