What is uglifyjs
uglifyjs is:
UglifyJS is a JavaScript compressor/minifier written in JavaScript. It also contains tools that allow one to automate working with JavaScript code:
- A parser which produces an abstract syntax tree (AST) from JavaScript code.
- A code generator which outputs JavaScript code from an AST, also providing the option to get a source map.
- A compressor (optimizer) - it uses the transformer API to optimize an AST into a smaller one.
- A mangler - reduce names of local variables to (usually) single-letters.
- A scope analyzer, which is a tool that augments the AST with information about where variables are defined/referenced etc.
- A tree walker - a simple API allowing you to do something on every node in the AST.
- A tree transformer - another API intended to transform the tree.
All the above utilities and APIs are defined in ~6500 lines of code (except for the effective generation of the source-map, which is handled by the source-map module). Compared to alternatives, UglifyJS is pretty small.
