eslint-plugin-json-light

1.0.3 verified Sat Apr 25 auth: no javascript maintenance

ESLint plugin for validating JSON files. Version 1.0.3 (last updated in 2016, no releases since). Lightweight alternative to eslint-plugin-json, which required downloading PhantomJS (~22MB). This plugin has zero dependencies and simply parses JSON files to report syntax errors. Key differentiator is its minimal footprint, but it lacks features like auto-fix or extended syntax checks. Suitable for basic JSON linting in ESLint workflows.

Common errors

error ESLint couldn't find the plugin "eslint-plugin-json-light". ↓

cause Plugin not installed or not in package.json dependencies.

fix

Run: npm install eslint-plugin-json-light --save-dev

error Parsing error: Unexpected token } ↓

cause JSON file contains a syntax error (e.g., extra comma).

fix

Fix the JSON syntax in the file.

error Error: .json files are ignored by default in ESLint. Use --ext .json or add 'json' to lint-staged patterns. ↓

cause ESLint does not lint .json files by default.

fix

Run: eslint . --ext .json or configure lint-staged to include *.json

Warnings

gotcha This plugin only validates JSON syntax; it does not provide any rules (like 'no-trailing-comma'). It only reports parse errors. ↓

fix If you need JSON rules, consider eslint-plugin-json or write custom rules.

deprecated Last release was in 2016. Consider using modern alternatives like eslint-plugin-jsonc or eslint-plugin-json-format. ↓

fix Migrate to eslint-plugin-jsonc (supports comments) or other actively maintained plugins.

gotcha Plugin is installed as 'eslint-plugin-json-light' but used in plugins array as 'json-light' (drop the prefix). ↓

fix Add 'json-light' to plugins, not 'eslint-plugin-json-light'.
