esmangle (esmangle) is mangler / minifier for Parser API AST.
esmangle can be used in a web browser: Download
<script src="esmangle.js"></script>
Node.js application via the package manager:
If you would like to use latest esmangle in a browser, you can build build/esmangle.min.js:
A simple example: the program
var ast = esprima.parse(code); var result = esmangle.mangle(ast); // gets mangled AST console.log(escodegen.generate(result)); // dump AST
Or you can simply use this esmangle command in the shell.
Get more compressed result: (in Node.js)
var ast = esprima.parse(code);
// Get optimized AST
var optimized = esmangle.optimize(ast, null);
// gets mangled AST
var result = esmangle.mangle(optimized);
console.log(escodegen.generate(result, {
format: {
renumber: true,
hexadecimal: true,
escapeless: true,
compact: true,
semicolons: false,
parentheses: false
}
})); // dump AST
Slide is here. This resolution algorithm is based on my bytecode compiler iv / lv5 / railgun.
