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.
.
This package provides UglifyJS library
usable with Node.JS.
