Status: BETA - Mostly stable API undergoing wider testing.
The loader allows for bootstrapping a state-of-the-art, consistent and portable CommonJS environment
for any supported platform (on servers, in browsers, desktop applications, secure sandboxes, and embedded) and thus
is ideally suited to be used as the target for the
commonjs command (currently being standardized) and the
This module loader brings CommonJS Modules/2 (currently in draft) plus CommonJS Packages, Package Mappings and further concepts to the following platforms:
commonjs- Use it as a target for the
commonjscommand being standardized
- NodeJS - Use it in any NodeJS application (Default CLI and utility platform until API adapters come along)
- Jetpack - Use it in any Gecko/XULRunner extension or application
- v8cgi - Use it in any v8cgi application
- GPSEE - Use it in any GPSEE application
- RingoJS - Use it in any RingoJS application
- Narwhal - Use it with any Narwhal engine platform
- Titanium - Use it in any Appcelerator Titanium application
- AdobeAir - Use it in any AdobeAir application
- Wakanda (In Progress)
- CouchApp (Initial exploration)
- PhoneGap (Initial exploration)
- PhantomJS (Not Yet Implemented)
- IronJS (Not Yet Implemented)
- SilkJS (Not Yet Implemented)
- Rhino (Not Yet Implemented)
Browser - For development and optimized production purposes
- BravoJS - Default browser loader with full CommonJS package support (11.8 KB minified & gziped)
- PINF Browser Loader - Optimized production browser loader with goal of < 3 to 5 KB minified & gziped (Not Yet Implemented)
- NobleJS (Not Yet Implemented)
- RequireJS (Not Yet Implemented)
- bdLoad (Not Yet Implemented)
- Dojo (Not Yet Implemented)
The loader implements or is compatible with the following specs:
- CommonJS Modues/1.1.1 (approved)
- CommonJS Modues/2.0draft8 (draft)
- CommonJS Modules/AsynchronousDefinition (proposal) (partial)
- CommonJS Packages/1.1 (draft)
- CommonJS Packages/Mappings/C (proposal)
- CommonJS Modules/LoaderPlugin (proposal) (partial)
The loader extends the core CommonJS platform defined by the above specifications with the following additions:
- CommonJS Programs/A (strawman) (Not Yet Documented)
- Various additions and generalizations to be able to load a wide range of packages. (Not Yet Documented)
The loader can be used:
- By calling it from the command line to run a program
require()ing it from any CommonJS module to load a sub-program
- By setting it up as a package server to load programs into a browser
- To export CommonJS programs to be loaded by CommonJS compliant loaders
- Aims to be complete and fully specification compliant where possible.
- Aims to validate the CommonJS Program and Mappings approaches and inform CommonJS specifications.
- Provisions and executes programs by downloading and linking dependencies on first use.
- By default isolates the dependencies for each program.
- Can provision complex applications (programs) composed of hundreds of packages by contacting an open network of public registry and repository servers. (Not Yet Implemented)
- Can load complex applications (programs) composed of hundreds of packages from Content Delivery Networks fed by a simple program server. (Not Yet Implemented)
- Supports REMOTE LIVE application DEBUGGING and EDITING for DEPLOYED applications running on any ANY PLATFORM (
eval()or equivalent required). (Not Yet Implemented)
The loader is a sub-project of the PINF Toolchain Automation Platform where an application (program) is a view into the toolchain that statically links package-based dependencies.
The toolchain is an organized body of code & services maintained collectively for the purpose of automating software production and system operation. Any CommonJS package may be used as part of the toolchain.
- UNIX system (Windows support is under development but still has some way to go)
- NodeJS: http://nodejs.org/
Use any one of the following install solutions:
npm install -g pinf-loader-js cd ~/ wget -O pinf-loader-js.tar.gz https://github.com/pinf/loader-js/tarball/master tar -zxf pinf-loader-js.tar.gz mv pinf-loader-js-* pinf-loader-js alias commonjs='~/pinf-loader-js/pinf-loader.sh' cd ~/ git clone git://github.com/pinf/loader-js.git pinf-loader-js alias commonjs='~/pinf-loader-js/pinf-loader.sh'
Make sure it works:
To install additional platforms (other than
- Individual platform projects
To run the loader on a different platform (other than
commonjs --platform <PlatformAlias> ...
<PlatformAlias> is any of
NOTE: Not all features are supported on all platforms yet due to incomplete API adapters.

Setup - Setup your
- Demos - Looking at the source code of the demos is a good place to start.
- Use Cases - The loader can be used in various ways.
- Writing Programs - A quick introduction.
Source Overlays - Use cloned source code instead of downloaded archive for a package.
