indent.js - pure code indentation for js, jsx, json, ts, tsx, html, css, less, scss

Fast, minimalistic, pure code indentation. Indents JavaScript, JSON, JSX, Typescript, TSX, CSS, LESS, SCSS, and HTML. Unlike JSBeautify, which adds new lines when reformatting code and changes single line expressions, indent.js preserves new lines in when indenting it. Indent.js is coded with simple, but universal, and unopinionated rules.

Indent.js is thoroughly tested to make sure it correctly indents all styles, and types of code.
