rebundler

Simple reuse of cache from previous browserify builds. Supports cache invalidation without file watching and speeds up bundling.

Usage

var rebundler = require("rebundler");
var entry = rebundler(function(cache, packageCache) {
  return browserify("./entry.js", {
    cache: cache,
    packageCache: packageCache,
    fullPaths: true
    // ... other options
  })
  .transform('brfs')
  //... etc
});
 
// ...
 
// GET /entry.js will be slow the first time, but all subsequent requests will re-use
// the cache from the previous build and be much faster
 
app.get("/entry.js", function(req, res) {
  entry()
    .bundle()
    .pipe(res);
});

API

rebundler([options], browserifyFn)

Where browserifyFn is a function that accepts a cache and packageCache arguments and returns a browserify instance. Important: The returned browserify instance must have its fullPaths option set to true.

rebundler(browserifyFn) Returns a function that, when called, will pass the cache from its previous call to the browserifyFn and return the created browserify instance. If any of the files included in the previous build has changed, they will be removed from the cache, and re-analyzed again by browserify.

Options:

• noop: true|false Default false. If set to true, no cache checks/invalidation will be performed and the browserifyFn will be passed empty cache and packageCache objects on every call.
• persist: true|false Default false. If set to true, rebundler will dump cached dependencies to a file on disk, and restore cache from this file when initialized later on.
• persistKey: <string> Defaults to undefined. Set this if creating multiple bundles in the same working directory.
• cacheDir: <string> Defaults to ./.rebundler-cache. If set, will move the cache directory.
