How to keep the size of the Browserify buffer reasonable when used, is required for third party material (through grunting, if that matters)

I am trying to link my own code (A), which in turn uses 2 third-party components (B and C), where C also needs B. Everything, as far as I know, is written using CommonJS node style modules.

A by itself when it comes bundled with 60K.

B is turned on separately and is considered global, it works fine for me, performing a dirty replacement bit at my build stage, which requires swapping ("B") with global.B.

C is what causes me problems, although its value should be “only 8K” in size, but when I try to associate it with A, my package jumps to 600K +, since I assume that its pull in dependencies is abundant?

This is unacceptable, but I don’t know how to reduce it, since I don’t know what the hell it is (or more importantly, I can exclude that it still works). I could try the binary beat with explosions, but I would not know if this is safe or even a reasonable way to do it.

How can I bundle C up and only get my package at 68.5K (the total size of both blocks of code is 60k + 8.5k) and of course it still works?

I am new to node and scrolling, but I have been tapping this week for so long to say that I gave him a good punch before raising my hand.

Additional information if this is important:

  • he needs to start the server and client sides
  • B actually ReactJS
  • C is actually a React Router component
  • Using windows and C # through ReactJS.net ... hey ... wait ... come back ... tumble-box.

If you create an external package containing all the dependencies of your application (B + C) and declare these modules as external when linking your own application code (A), then everything should work as you expect.

I don't know the grunt-browsify configuration hints for this, but the following shows how you will use the browser directly in some gulp examples, so package creation should be reused:

var browserify = require('browserify') var gulp = require('gulp') var source = require('vinyl-source-stream') gulp.task('js-deps', function() { var b = browserify() b.require('react') b.require('react-router-component') b.transform('envify') return b.bundle() .pipe(source('deps.js')) .pipe(gulp.dest('./build')) }) gulp.task('bundle-js', function() { var b = browserify('./lib/app.js') b.external('react') b.external('react-router-component') return b.bundle() .pipe(source('app.js')) .pipe(gulp.dest('./build')) })

Someone else mentioned an external option, which should be the actual solution. Now consider these tips. You can know most, if not all, of them already, but some of them may help. This will not turn a 600k file into 1k, but it can be significant nonetheless.

Start by checking the advanced options https://github.com/substack/node-browserify#usage and, more specifically, the -no-bundle-external options. If an external parameter works with require ('b') but still includes external libraries, this is your best bet;

Also consider options for global variables. When I started working with the browser, I had one function compiled into a huge library, as it contained all the stubs for its own NodeJS modules. The above options were key in solving this problem. This was in the Grunt task, but if I remember correctly, it was not with the grunt-browsify task, it can still be relevant.

Install the build environment before launching the browser: application, if you have not already done so. There are libraries that depend on these variables for their production compilation (I think React is one of them).

  grunt.loadNpmTasks('grunt-env'); // initConfig task env: { dist: { NODE_ENV : 'production', }, dev: { NODE_ENV: 'development', } } grunt.registerTask("build_dist", ['env:dist', 'browserify:app']

Try running Uglify with these parameters defined;

  // initConfig task options options: { compress:{ dead_code : true, // discard unreachable code drop_debugger : true, // discard "debugger" statements global_defs : { // global definitions "DEBUG": false, // matters for some libraries }, } }

You can optimize a lot more, but this should help you get started.

B is included separately and is considered global, it works fine for me, performing a dirty replacement bit at my build stage, which requires swapping ("B") with global.

If you upgrade to global.B after compilation, your package will have all the necessary ('b') dependencies. This hack is (possibly) better:

This is unacceptable, but I don’t know how to reduce it, since I don’t know what the hell it is (or more importantly, I can exclude that it still works).

Go to the source code of the generated library, you should be able to identify the different modules and their path to the files.

I put together a working example for splitting code into multiple packages using Browserify: https://github.com/aldendaniels/browserify-bundle-splitting

With this approach, you can download all of your vendor code through Browserify (no global configuration is required), but you have your own code separately.

Since the created bundles are truly independent, you can easily have different settings for the generated packages. For example, you can disable source maps for third-party code, but use source maps for your own code.

You can see which files take up space in the bundle by running this command: browserify --list test/browser/browserify-test-uncompiled.js | xargs ls -la | sort browserify --list test/browser/browserify-test-uncompiled.js | xargs ls -la | sort
