library2.0.3jsnpmunverified

ESLint plugin providing TypeScript-focused, general-purpose lint rules. Current version 2.0.3 (stable). The package reimplements TSLint-etc rules for ESLint, covering areas like array mutation, commented-out code, const enums, deprecated APIs, and more. It requires TypeScript 4.0+ and ESLint 8. Some rules are opinionated and excluded from the recommended config, giving developers flexibility. Compared to @typescript-eslint/eslint-plugin, it offers unique rules like no-t, no-const-enum, and no-implicit-any-catch for Promise rejections.

Verified usage

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

plugin

✓ plugins: ['etc']

✗ const plugin = require('eslint-plugin-etc'); // incorrect usage in config

Add 'etc' to the plugins array in your ESLint config.

etc/recommended

✓ extends: ['plugin:etc/recommended']

✗ extends: ['etc/recommended'] // missing 'plugin:' prefix

Use 'plugin:' prefix for extending configurations.

rules

✓ rules: { 'etc/no-t': 'error' }

✗ rules: { 'no-t': 'error' } // missing 'etc/' prefix

Prefix rule names with 'etc/' as they are namespaced.

Configure eslint-plugin-etc with TypeScript parser and recommended rules. Shows plugins, extends, and custom rule setup.

// In .eslintrc.js const { join } = require('path'); module.exports = { parser: '@typescript-eslint/parser', parserOptions: { ecmaVersion: 2019, project: join(__dirname, './tsconfig.json'), sourceType: 'module' }, plugins: ['etc'], extends: ['plugin:etc/recommended'], rules: { 'etc/no-t': 'error' } };

Debug

Known issues

breakingVersion 2.0.0+ may have changed configuration schema or dropped rules; check migration docs.

fix

Review the changelog on GitHub for breaking changes.

affects: >=2.0.0

deprecatedSome rules have been deprecated or renamed from the original tslint-etc set.

fix

Check the documentation for each rule to ensure you are using the correct name.

affects: >=1.0.0

gotchaThe 'no-deprecated' rule requires a TypeScript project and may produce false positives if type information is incomplete.

fix

Ensure the parserOptions.project points to a valid tsconfig.json and type information is available.

affects: >=1.0.0

gotchaSome opinionated rules (e.g., no-enum, no-const-enum) are not in the 'recommended' config and need explicit enabling.

fix

Add the rule to your 'rules' object with the desired severity.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'eslint-plugin-etc'

The plugin is not installed globally or locally.

fix

Run 'npm install eslint-plugin-etc --save-dev'.

Configuration for rule 'etc/no-t' is invalid: Value "error" should be a boolean.

Old syntax using 'true' instead of 'error'/'warn'/'off'.

fix

Use 'error' or 'warn' instead of 'true'.

Parsing error: The 'project' option must be set to a path to a tsconfig.json file.

Missing or incorrect parserOptions.project in ESLint config.

fix

Set parserOptions.project to a valid path to your tsconfig.json.
