require just like in Node. Put another way, you can reuse server-side code in the browser and still use
require and NPM.
To browserify, which was the original inspiration for Ark, and from which I took some code, such as the HTTP implementation.
Speaking Of Which ...
The obvious question is: how is Ark different than browserify?
Ark is more CoffeeScript-friendly. You don't need to add a transform or plugin to bundle CoffeeScript into your Ark. Also, most of Ark is actually implemented in CoffeeScript in case you want to fork or submit patches.
Ark uses a CSON manifest file to decide what to package up, so you have complete control over what's being shipped to the browser. Use glob expansion and exclusion to make it easy.
Ark does not use the
Ark allows you to include any arbitrary files into your ark. You can then use the node
fsAPI to read them. For example, we often bundle a configuration file that tells us where to find various backend resources.
Ark is just simpler, both in terms of usage and implementation.
npm install -g ark
arkdirectory in your source tree. Put stuff in that directory that you want to ship to the browser. In Ark parlance, that stuff is called "the ark."
Add in a
package.jsonfile to set the entry point for your ark (using the
manifest.csonfile with the list of files and emulated Node APIs you want to bundled in your ark.
Package up your ark:
The manifest file might look like this:
root: "/Users/dan/Projects/ark/test" files: [ "**/*.coffee" "package.json" ] apis: [ "assert", "child_process", "crypto", "events", "fs", "http", "https", "module", "path", "querystring", "stream", "sys", "tty", "url", "util" ]
That's it. There's never any question about which files or APIs are included, because you control it via the manifest. Also, we can use any glob pattern in our list of files to save typing.
You can also exclude files. For example, if you want to make sure that no files within test directories are committed, you might do something like this:
root: "/Users/dan/Projects/ark/test" files: [ "**/*.coffee" "package.json" ] exclude: [ "**/test/**" "**/spec/**" ] apis: [ "assert", "child_process", "crypto", "events", "fs", "http", "https", "module", "path", "querystring", "stream", "sys", "tty", "url", "util" ]
Checking The Manifest
If you use glob expansion, you might want to see exactly what the result of the expansion is -- you can do this by using the list command:
ark ls -m <manifest>
To package up your ark only if it's out-of-date, use the
See the man page for more, or just type
You can also use Ark programmatically. It's pretty simple:
Ark = require "ark" Ark.package manifest: "./ark.cson" file: "js/application.js"
Other options include:
- compilers. This is just an object with file extensions as keys and functions that take a string and transform it somehow. The default compilers include one for CoffeeScript, but using this mechanism, you can include others.
required. You might write an Ark compiler like this:
compileJade = do -> jade = require "jade" options = client: true compileDebug: false (template) -> jade.compile template, options Ark.package manifest: "./ark.cson" file: "js/application.js" compilers: ".jade": compileJade
file. This is just the path of the output file. If it's undefined, Ark will write to
To run a command conditionally based on whether your Ark is out-of-date, use the
mtime function, like this:
Ark.mtime manifest: "./ark.cson" file: "js/application.js" -> console.log "The Ark must be rebuilt!"
You can also generate the full manifest, after glob expansion, with
list, which returns an array of relative paths.
console.log "Your ark will include:", Ark.list manifest: "./ark.cson" file: "js/application.js"
Ark is under active development but is not yet production-ready.
