eslint-plugin-rxjs-x

library1.0.2jsnpmunverified

Modern ESLint plugin for RxJS, forked from the unmaintained eslint-plugin-rxjs. v1.0.2 requires ESLint ^10.0.1, Node ^20.19.0 || ^22.13.0 || >=24, and RxJS ^7.2.0 with TypeScript >=4.8.4 <6.1.0. Ships TypeScript types. Offers flat-config-only recommended and strict configs, with 33+ rules. Breaking from v0.x: ESLint 10 required, Node 18 dropped, eslintrc unsupported, and namespace changed from 'rxjs' to 'rxjs-x'. Provides typed linting via dependency on typescript-eslint.

Verified usage

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

default import

✓ import rxjsX from 'eslint-plugin-rxjs-x'

✗ const rxjsX = require('eslint-plugin-rxjs-x')

ESM-only; CommonJS require() is not supported.

configs

✓ rxjsX.configs.recommended

✗ rxjsX.configs['recommended']

Access via property, not bracket notation with string key.

rules prefix in inline comments

✓ // eslint-disable-next-line rxjs-x/no-subject-value

✗ // eslint-disable-next-line rxjs/no-subject-value

Namespace changed from 'rxjs' to 'rxjs-x' in v1.0.0.

flat config with typescript-eslint

✓ import tseslint from 'typescript-eslint'; import rxjsX from 'eslint-plugin-rxjs-x'; export default tseslint.config({ extends: [...tseslint.configs.recommended, rxjsX.configs.recommended], languageOptions: { parserOptions: { projectService: true } } })

✗ module.exports = { plugins: ['rxjs-x'], extends: ['plugin:rxjs-x/recommended'] }

eslintrc style configs are not supported in v1.0.0; only flat config with import/export.

Sets up ESLint flat config with typescript-eslint and eslint-plugin-rxjs-x recommended rules for typed RxJS linting.

// @ts-check import { defineConfig } from 'eslint/config'; import tseslint from 'typescript-eslint'; import rxjsX from 'eslint-plugin-rxjs-x'; export default defineConfig({ extends: [ tseslint.configs.recommended, rxjsX.configs.recommended, ], languageOptions: { parserOptions: { projectService: true, }, }, });

Debug

Known issues

breakingESLint v10 required; Node.js v18 support dropped.

fix

Upgrade to ESLint ^10.0.1 and Node.js ^20.19.0 || ^22.13.0 || >=24.

affects: >=1.0.0

breakingeslintrc config no longer supported; only flat config with import/export.

fix

Migrate to flat config using import statements and defineConfig.

affects: >=1.0.0

breakingNamespace changed from 'rxjs' to 'rxjs-x'; all rule references must be updated.

fix

Replace 'rxjs/' with 'rxjs-x/' in all ESLint config rules and inline disable comments.

affects: >=1.0.0

breakingRule 'rxjs/no-ignored-observable' replaced by 'rxjs-x/no-floating-observable'.

fix

Use 'rxjs-x/no-floating-observable' instead of 'rxjs/no-ignored-observable'.

affects: >=1.0.0

deprecated'recommended-legacy' config removed in v1; use flat config only.

fix

Use rxjsX.configs.recommended in flat config.

affects: >=1.0.0

gotchaTyped linting requires projectService: true in parserOptions.

fix

Add 'projectService: true' to parserOptions; otherwise type-dependent rules won't work.

affects: >=1.0.0

gotchaPeer dep upper bounds: rxjs ^7.2.0, typescript <6.1.0.

fix

Ensure RxJS is ^7.2.0 and TypeScript >=4.8.4 <6.1.0.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'eslint-plugin-rxjs-x'

Package not installed or wrong import path.

fix

npm install eslint-plugin-rxjs-x --save-dev

Configuration for rule "rxjs-x/no-subject-value" is invalid: Value "error" is not a valid severity.

Using old eslintrc syntax with 'extends' containing 'plugin:rxjs-x/recommended'.

fix

Use flat config: import rxjsX from 'eslint-plugin-rxjs-x' and extend rxjsX.configs.recommended.

TypeError: eslint-plugin-rxjs-x is not a function

Using require() instead of import in flat config.

fix

Use 'import rxjsX from 'eslint-plugin-rxjs-x'' in ESM context.

Parsing error: ESLint was configured to run on files that are not included in the project's TypeScript configuration.

Missing 'projectService: true' or TypeScript config not found.

fix

Add 'projectService: true' to parserOptions and ensure tsconfig is present.

Cannot read properties of undefined (reading 'configs')

Importing default export incorrectly in CommonJS.

fix

Switch to ESM or use dynamic import: const rxjsX = await import('eslint-plugin-rxjs-x').then(m => m.default);
