convert bundle paths to IDs to save bytes in browserify bundles
var collapse = require('bundle-collapser');
var fs = require('fs');
var src = fs.readFileSync(__dirname + '/bundle.js', 'utf8');
collapse(src).pipe(process.stdout);
The input bundle has require(string)
paths in it:
(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){
module.exports = function (n) { return n * 5 }
},{}],2:[function(require,module,exports){
var bar = require('./bar.js');
module.exports = function (n) { return bar(n+1) }
},{"./bar.js":1}],3:[function(require,module,exports){
var foo = require('./foo.js');
var bar = require('./bar.js');
console.log(foo(5) * bar(2));
},{"./bar.js":1,"./foo.js":2}]},{},[3]);
but the output just has the integers:
(function e(t,n,r){function s(o,u){if(!n[o]){if(!t[o]){var a=typeof require=="function"&&require;if(!u&&a)return a(o,!0);if(i)return i(o,!0);var f=new Error("Cannot find module '"+o+"'");throw f.code="MODULE_NOT_FOUND",f}var l=n[o]={exports:{}};t[o][0].call(l.exports,function(e){var n=t[o][1][e];return s(n?n:e)},l,l.exports,e,t,n,r)}return n[o].exports}var i=typeof require=="function"&&require;for(var o=0;o<r.length;o++)s(r[o]);return s})({1:[function(require,module,exports){
module.exports = function (n) { return n * 5 }
},{}],2:[function(require,module,exports){
var bar = require(1);
module.exports = function (n) { return bar(n+1) }
},{}],3:[function(require,module,exports){
var foo = require(2);
var bar = require(1);
console.log(foo(5) * bar(2));
},{}]},{},[3]);
There is also a command-line program included in this distribution:
usage: bundle-collapser {FILE | -} {OPTIONS}
Collapse a browser-pack/browserify bundle from STDIN or a FILE.
OPTIONS:
-h --help Show this message.
var collapse = require('bundle-collapser')
Return a readable stream
of output from
browser-pack with the input source
string src
converted to have its require()
calls collapsed down to the
dependency targets in the "deps" fields from the unpacking.
With npm, to get the library do:
npm install bundle-collapser
and to get the command-line program do:
npm install -g bundle-collapser
