eslint-parser-plain

library0.1.1jsnpmunverified

ESLint parser that allows linting of various plain text file types (e.g., Markdown, JSON, YAML) by treating them as plain text strings. Version 0.1.1 is the current stable release with a slow release cadence. It is designed for use with ESLint's parser option to enable linting rules (like prettier/prettier) in non-JavaScript files. Differentiates from @eslint/markdown by being simpler and file-type agnostic.

Verified usage

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

Exported since v0.1.1. Use to access parser metadata (e.g., name, version).

import { parserMeta } from 'eslint-parser-plain'

The default export is an object with parse and parseForESLint methods. ESM-only; require() will fail in CJS contexts.

import parser from 'eslint-parser-plain'

Named export for the ESLint parser API. Same ESM restriction applies.

import { parseForESLint } from 'eslint-parser-plain'

Configures ESLint to use eslint-parser-plain for .md and .json files, enabling prettier rules on them.

// .eslintrc.cjs module.exports = { overrides: [ { files: ['*.md', '*.json'], parser: 'eslint-parser-plain', rules: { 'prettier/prettier': ['error', { parser: 'markdown' }], }, }, ], };

Debug

Known footguns

gotchaeslint-parser-plain does not perform syntax validation; it treats all input as plain text. This may hide syntax errors in files like JSON.

breakingESM-only package: using require('eslint-parser-plain') will throw 'ERR_REQUIRE_ESM'.

gotchaThe package's parse method returns an object with an 'ast' property set to a minimal token (e.g., { type: 'Program', body: [] }), not a full AST. This may break tools expecting a standard ESTree AST.

deprecatedNo known deprecations; all current APIs are stable.
