any-eslint-parser

1.0.1 verified Sat Apr 25 auth: no javascript

Check any file type with ESLint using a parser that ignores AST-based rules, allowing text-based rules like eol-last and no-tabs to be applied to non-JavaScript files (e.g. JSON, YAML, Markdown, XML, etc.). Current stable version is 1.0.1. The package has no release cadence documented and is a niche tool for leveraging ESLint's text-based rules across diverse file formats. Differentiators include zero AST dependency for linting, compatibility with eslint-plugin-regex, and ability to use existing ESLint configuration infrastructure.

Common errors

error Parsing error: The keyword 'import' is reserved ↓

cause Parser tries to parse non-JavaScript file as JavaScript because default parser is espree.

fix

Set parser to 'any-eslint-parser' in the ESLint config for the file patterns.

error Error: Failed to load parser 'any-eslint-parser' ↓

cause any-eslint-parser is not installed; missing npm package.

fix

Run 'npm install --save-dev any-eslint-parser' to install the parser.

error No ESLint configuration found ↓

cause Using --no-eslintrc without providing a config file via --config.

fix

Specify the config file with '--config /path/to/.eslintrc-any.json'.

Warnings

gotcha AST-based rules like no-unused-vars are ignored silently; no error is thrown but they produce no effect. ↓

fix Use only text-based rules (e.g. eol-last, no-tabs, eslint-plugin-regex rules) in the parser's config.

gotcha Using any-eslint-parser without --no-eslintrc may cause unexpected behavior if parent configs contain AST rules. ↓

fix Pass --no-eslintrc to eslint to ignore all other config files, or use a dedicated eslintrc file for any-eslint-parser.

deprecated No deprecation warnings in package.

breaking No breaking changes documented; version 1.0.1 is the only release.

Install

npm install any-eslint-parser

yarn add any-eslint-parser

pnpm add any-eslint-parser

Imports

any-eslint-parser

wrong

Using "parser": "any-eslint-parser" in a JavaScript file (it's a config option, not an import)

correct

In .eslintrc: { "parser": "any-eslint-parser" }

Parser is used in ESLint configuration, not imported directly in code.

eslint

wrong

eslint "**/*.json" (without specifying the parser config)

correct

npx eslint --config .eslintrc-any.json --no-eslintrc "**/*.json"

Since v1.0.0, using --no-eslintrc is recommended to avoid AST-based rules from other configs.

defaultParser
wrong
```
import anyEslintParser from 'any-eslint-parser'
```
correct
```
Not applicable; there is no exported symbol.
```
Package exports no JavaScript API; it's only a parser for ESLint config.

Quickstart

Sets up ESLint with any-eslint-parser to lint JSON, YAML, XML, Markdown, and other text files for trailing newlines and tabs.

// 1. Install dependencies
// npm install --save-dev any-eslint-parser eslint

// 2. Create .eslintrc-any.json with parser and text-based rules
// { "parser": "any-eslint-parser", "rules": { "eol-last": "error", "no-tabs": "error" } }

// 3. Run eslint with the custom config
// npx eslint --config .eslintrc-any.json --no-eslintrc "**/*.+(json|yml|xml|md|txt|sh)"

// Example output for a JSON file with tabs:
// 1:1  error  Unexpected tab character  no-tabs
// 2:1  error  Newline required at end of file but not found  eol-last
