Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

grunt-browserify

Grunt task for node-browserify.

Getting Started

This plugin requires Grunt ~0.4.0.

Install this grunt plugin with:

npm install grunt-browserify --save-dev

Then add this line to your project's grunt.js Gruntfile:

grunt.loadNpmTasks('grunt-browserify');

3.0 Release

An important note for those running the latest release of grunt-browserify: the newest version (>3.0) incorporates breaking changes from Browserify which REMOVED BUNDLE OPTIONS. All options to browserify must now be passed in the browserifyOptions hash.

In the Wild

Most simply, Browserify is a tool for taking your CommonJS-style Javascript code and packaging it for use in the browser. Grunt-Browserify provides the glue to better integrate Browserify into your Grunt-based development workflow.

For JavaScripters unfamiliar with CJS-style code and the Node ecosystem, moving to Browserify can be a bit confusing. Writing your client-side code as CJS modules allows for smaller, easier to understand files that perform one task well. These modules, because of their simplicity, will be significantly easier to use across projects. CJS modules also help to expose the dependency graph inherent in your code, allowing you to write cleaner, more-maintainable modules. As Alex MacCaw writes:

CommonJS modules are one of the best solutions to JavaScript dependency management.

CommonJS modules solve JavaScript scope issues by making sure each module is executed in its own namespace. Modules have to explicitly export variables they want to expose to other modules, and explicitly import other modules; in other words, there's no global namespace.

(A note to AMD fans that the benefits above are not unique to the CJS style of writing JavaScript modules, but the ease-of-interoperability with Node.JS code is a plus of CJS.)

As you begin to write your client-side code in small, reusable modules, you start to have a lot more files to manage. At the same time, you need to integrate these files with other client-side libraries, some of which do not play particularly nicely with a CJS module system. The simplicity provided by CJS modules can be lost as build complexity is increased and Browserify compilation time gets out of control.

Documentation

Run this task with the grunt browserify command. As with other Grunt plugins, the src and dest properties are most important: src will use the Grunt glob pattern to specify files for inclusion in the browserified package, and dest will specify the outfile for the compiled module.

The current version of grunt-browserify sticks as close to the core browserify API as possible. Additional functionality can be added via the rich ecosystem of browserify transforms and plugins.

The following task options are supported:

alias

Type: Object{alias:path}

Browserify can alias files or modules to a certain name. For example, require('./foo') can be aliased to be used as require('foo').

options: {
  alias: {
    'foo': './foo.js'
  }
}

The alias option is just a shortcut to require a file and expose a different name for it. You could do exactly the same thing using require instead of alias. It's equivalent to require: [ ['./foo.js', {expose: 'foo'} ] ]

If you need alias mappings, you can use @joeybaker's remapify plugin, as demonstrated in the code below:

options: {
  plugin: [
    [
      'remapify', [{
          src: './client/views/**/*.js',  // glob for the files to remap
          expose: 'views', // this will expose `__dirname + /client/views/home.js` as `views/home.js`
          cwd: __dirname  // defaults to process.cwd()
        }
      ]
    ]
  ]
}

banner

Type: String Default: empty string

The string will be prepended to the output. Template strings (e.g. <%= config.value %> will be expanded automatically.

require

Type: [String] or [String:String] or [[String, Object]]

Specifies files to be required in the browserify bundle. String filenames are parsed into their full paths with path.resolve. Aliases can be provided by using the filePathString:aliasName format.

Each require can also be provided with an options hash; in this case, the require should be specified as an array of [filePathString, optionsHash].

ignore

Type: [String]

Specifies files to be ignored in the browserify bundle. String filenames are parsed into their full paths with path.resolve. Globbing patterns are supported.

exclude

Type: [String]

Specifies files or modules to be excluded in the browserify bundle. Globbing patterns are supported; globbed filenames are parsed into their full paths.

external

Type: [String] or Object{alias:path}.

Specifies id strings which will be loaded from a previously loaded, “common” bundle. That is to say, files in the bundle that require the target String will assume that the target is provided externally.

The secondary form of this option follows the format of alias above, and will externalise the ids specified in the alias object. This second form allows for the declaration of a single alias object which can be supplied to one bundle's alias option and another option's external option.

In either case, globbing patterns are supported.

transform

Type: [String || Function] or [[String || Function, Object]]

Specifies a pipeline of functions (or modules) through which the browserified bundle will be run. The transform can either be a literal function, or a string referring to a NPM module. The browserify docs themselves explain transform well, but below is an example of transform used with grunt-browserify to automatically compile coffeescript files for use in a bundle:

browserify: {
  dist: {
    files: {
      'build/module.js': ['client/scripts/**/*.js', 'client/scripts/**/*.coffee']
    },
    options: {
      transform: ['coffeeify']
    }
  }
}

Transforms can also be provided with an options hash; in this case, the transform should be specified as an array of [transformStringOrFn, optionsHash].

Note for browserify-shim, the configuration of this transformation has to be inside package.json. Please see documentation of browserify-shim and our example.

plugin

Type: [String || Function] Register a browserify plugin with the bundle. As with transforms, plugins are identified with either their NPM name (String) or a function literal.

browserify: {
  dev: {
    options: {
      plugin: [
        'coffeeify', // register plugin by name
        ['browserify-hmr', { noServe : true }] // register plugin with name and options
      ]
    }
  }
}

browserifyOptions

Type: Object

A hash of options that are passed to browserify during instantiation. Task-level browserifyOptions are not merged into target-level options. If a target overrides task-level browserifyOptions, it overrides all of it. Browserify Github README

watch

Type: Boolean If true, invoke watchify instead of browserify.

For watchify to work properly, you have to keep the process running. The option keepAlive can help you do that, or you can use another grunt-watch task.

cacheFile

Type: String

Set to location of browserify-incremental cache file and enable incremental builds via browserify-incremental. Mutually exclusive with watchify.

Note that unlike watchify, this setting is fully compatible with grunt-contrib-watch and should be used together with it.

keepAlive

Type: Boolean If true and if watch above is true, keep the Grunt process alive (simulates grunt-watch functionality).

watchifyOptions

Type: Object A hash of options that are passed to watchify during instantiation. Watchify Github README

configure

Type: Function (b)

An optional callback function that is invoked once before the bundle runs. This can be used for programatically configuring browserify using it's API. b is the browserify instance for the bundle.

preBundleCB

Type: Function (b)

An optional callback function, that will be called before bundle completion. b is the browerify instance that will output the bundle.

NB: This callback will be invoked every time the bundle is built so when used with the watch option set to true it will be called multiple times. Do not register transforms in this callback or they will end up being registered multiple times.

postBundleCB

Type: Function (err, src, next)

An optional callback function, which will be called after bundle completion and before writing of the bundle. The err and src arguments are provided directly from browserify. The next callback should be called with (err, modifiedSrc); the modifiedSrc is what will be written to the output file.

NB: This callback will be invoked every time the bundle is built so when used with the watch option set to true it will be called multiple times.
