eslint-plugin-erasable-syntax-only

library0.4.0jsnpmunverified

ESLint plugin to granularly enforce TypeScript's erasableSyntaxOnly flag. Current stable version 0.4.0. Requires Node.js >=20.18.0, ESLint >=9, @typescript-eslint/parser >=8, and TypeScript >=5. Differentiators: provides individual rules (enums, namespaces, parameter properties, import aliases) instead of a single blanket flag, enabling incremental adoption, editor suggestions, and type-aware enforcement. Recommended config includes all rules set to error. Active development with semver releases.

Verified usage

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

default

✓ import erasableSyntaxOnly from 'eslint-plugin-erasable-syntax-only'

✗ const erasableSyntaxOnly = require('eslint-plugin-erasable-syntax-only')

ESM-only; requires Node.js >=20.18.0 and a bundler/module system that supports ESM. CommonJS require will fail.

erasableSyntaxOnly.configs.recommended

✓ erasableSyntaxOnly.configs.recommended

✗ erasableSyntaxOnly.configs['recommended']

Accessing configs via string key is also valid; both work.

plugins

✓ plugins: { 'erasable-syntax-only': erasableSyntaxOnly }

When using eslintrc format (not recommended), plugin must be registered under the short name.

Shows how to add the plugin's recommended config to a flat ESLint configuration using typescript-eslint.

import eslint from '@eslint/js'; import erasableSyntaxOnly from 'eslint-plugin-erasable-syntax-only'; import tseslint from 'typescript-eslint'; export default tseslint.config( eslint.configs.recommended, tseslint.configs.recommended, erasableSyntaxOnly.configs.recommended, // 👈 ); // Then run ESLint on your TypeScript files

Known issues

breakingRequires Node.js >=20.18.0; earlier versions will fail.

fix

Update Node.js to version >=20.18.0.

affects: <20.18.0

breakingRequires ESLint >=9 (flat config only); not compatible with ESLint 8 or eslintrc.

fix

Upgrade ESLint to v9 or later, and migrate to flat config.

affects: <9

deprecatedv0.2.0 and earlier had minimal rule set; upgrade to latest for full feature set.

fix

Update to >=0.3.0 to include import-aliases and parameter-properties rules.

affects: <0.3.0

Errors

Common errors & fixes

Error [ERR_REQUIRE_ESM]: require() of ES Module /path/to/node_modules/eslint-plugin-erasable-syntax-only/dist/index.js from /path/to/.eslintrc.cjs not supported.

Package is ESM-only; CommonJS require is not allowed.

fix

Convert your ESLint config to ESM (flat config) and use import syntax, or ensure your bundler supports ESM.

ESLint: Failed to load plugin 'erasable-syntax-only' declared in '.eslintrc.json': Cannot find module 'eslint-plugin-erasable-syntax-only'

Plugin not installed, or ESLint version too old.

fix

Run 'npm install eslint-plugin-erasable-syntax-only --save-dev' and ensure ESLint >=9.
