This is a
playground to test code. It runs a full
Node.js environment and already has all of
npm’s 400,000 packages pre-installed, including
contentjs with all
npm packages installed. Try it out:

A streamlined, minimalistic game content pipeline built on Node.js. The library and tools can be set up to monitor multiple source directory trees for changes, and on command, execute data compilers for each modified file. The intent is to provide rapid iteration for game content while minimizing errors that might result from manually running a series of separate tools.
Currently, the filesystem watching functionality is not implemented. Instead, the core functionality is exposed as a set of command-line tools for compiling resources and then archiving them up into single files for efficient transfer and loading.
npm install -g contentjs
This installs a number of utilities accessible from the command-line.
Content.js is a toolset, not a Node module. When installed, a number of command-line utilities become available:
buildimplements the core content build process.
publishbuilds archives for each resource package.
For each utility you can specify
--help to see the command-line options.
The tools operate on a top-level entity referred to as a content project. This is nothing more than a root directory under which all source content is located. A content project has the following basic directory structure:
project_name/The root content project directory.
database/Stores all generated content database information.
packages/The root directory for all resource packages.
processors/The root directory for all data compilers.
pipeline.jsonThe content pipeline definition file.
platform.jsonThe set of recognized platform names.
publish.jsonConfiguration data for the
Most of the work occurs under the
packages directory. Within the
packages directory, source content packages are defined. Each content package is a directory with a name like
Core.source. The name of the content package is 'Core', and the '.source' identifies it as a source directory. Within the source content directory, you may organize files however you would like. The directory structure helps to define the name of the resource at runtime; for example:
Core.source/The source content package directory.
textures/The root textures directory.
brick.textureThe brick texture for the 'generic' platform.
brick.xbox360.textureThe brick texture for the 'xbox360' platform.
brick.ps3.textureThe brick texture for the 'ps3' platform.
At runtime, the 'Core' package would contain a resource named
textures/brick, which would contain the runtime data for the platform-specific version of the resource.
Resource identifiers consist of three parts, a name, zero or more properties, and a type. This data is all encoded in the file path:
For example, given a root content project path
/Users/foo/project, with a resource package at
/Users/foo/project/packages/Core.source, and a file within that package at
textures/armor.battered.ps3.texture we have:
Platform identifiers may be any string you wish. Edit the
platform.json file to define your platform identifiers. This JSON file contains a single array of string values, each of which represents a single platform identifier:
[ 'xbox360', 'ps3' ]
These identifiers will then be automatically recognized when they appear as part of the resource filename extension list, for example
Additionally, code is included to manage the downloading of these manifest and package files. The HTML5 IndexedDB API is used to cache downloaded packages on the client, speeding load times and allowing offline access while still allowing for content updates.
