jformatter

A JavaScript code formatter that formats JS files via CLI or API. Current version is 1.0.13 (last released in 2015). It uses esprima for AST parsing and offers many configuration options (indentation, spacing, quotes, semicolons, etc.) and auto-fix capabilities. However, the project is no longer actively maintained. It is similar to Prettier or JSBeautify but with a focus on configurability and auto-fixing common issues.
