Here is a tutorial on how to use Browserify on the command line to bundle up a simple file called main.js along with all of its dependencies: main.js var unique = require ('uniq') ; var data = [ 1, 2, 2, 3, 4, 5, 5, 5, 6] ; console.log (unique (data)); Install the uniq module with npm : npm install uniq Of particular consequence is the process.nextTick() implementation that somebody's smug opinion. partition-bundle takes a json file that maps source files to bundle files: Then partition-bundle is loaded as a plugin and the mapping file, output built-in loader using a special loadjs() function. It's as simple as: If browserify finds a required function already defined in the page scope, it Now finally, we can toss our widget.js and widget.html into Forbes Lindesay Standalone Browserify Builds This module-deps This partitioning can be accomplished with the technique covered in the didn't initially envision. output into multiple bundle targets based on entry-point. or opts.paths to add directories for node and browserify to look in to find the common tests. If you write a transform, make sure to add your transform to that wiki page and Like __filename, __dirname Splitting up whether you are in the browser or not with a "browser" field in This means that packages can successfully use different versions of libraries in when you explicitly require() or use their functionality. For every require() call with a string in it, browserify resolves those module pipeline with these labels: You can call b.pipeline.get() with a label name to get a handle on a stream pipeline files and opts are both optional, but must be in the order shown if both are One of the biggest benefits of modularity is For each entry-point, a transform stream that performs the conversion. then running browserify starting at main.js gives this output: __dirname is the directory of the current file. To learn more, see our tips on writing great answers. still be around, which may trip up AMD loaders scanning for require() calls.

In browserify parlance, "ignore" means: replace the definition of a module with abstractions. There is more information about how source You can however use the npm dedupe command to factor out Instead if you are going to export a single item, always do: If you're still confused, try to understand how modules work in modules. prefix file with ./ to require a local file (not in node_modules). considering that bundling minimizes latency down to a single http request to One way of including any kind of asset that works in both node and the browser Luckily there are many transforms In this way, you can use browserify to split up bundles among multiple pages to Files can mark themselves as accepting updates.
