This project is no longer actively maintained. Mostly, because we use Webpack in our projects now. I am happy to review incoming PRs, though. If you would like to become maintainer, please contact me. – @normanrz
An AMD (RequireJS) optimizer that's stream-friendly. Made for gulp. (WIP)
- Trace all dependencies of an AMD module
- Stream-friendly: Pipe in files and get an ordered stream of files out. No need for writing on disk in between.
- Support for precompilation of source files (ie. CoffeeScript)
- Wraps non-AMD dependencies
- Supply a custom loader for on-demand loading
- Leaves concatenation and minification to your preferred choice of modules
- gulp-sourcemaps support
var gulp = require("gulp");
var amdOptimize = require("amd-optimize");
var concat = require('gulp-concat');
gulp.task("scripts:index", function () {
return gulp.src("src/scripts/**/*.js")
// Traces all modules and outputs them in the correct order.
.pipe(amdOptimize("main"))
.pipe(concat("index.js"))
.pipe(gulp.dest("dist/scripts"));
});This aims to be an alternative to the powerful r.js optimizer, but made for a streaming environment like gulp. This implementation doesn't operate on the file system directly. So, there's no need for complicated setups when dealing with precompiled files. Also, this module only focuses on tracing modules and does not intend replace a full-fletched build system. Therefore, there might be tons of use cases where r.js is a better fit.
$ npm install amd-optimizeType: String
paths : {
"backbone" : "../bower_components/backbone/backbone",
"jquery" : "../bower_components/jquery/jquery"
}map : {
// Replace underscore with lodash for the backbone module
"backbone" : {
"underscore" : "lodash"
}
}shim : {
// Shimmed export. Specify the variable name that is being exported.
"three" : {
exports : "THREE"
},
// Shimmed dependecies and export
"three.color" : {
deps : ["three"],
exports : "THREE.ColorConverter"
},
// Shimmed dependencies
"bootstrap" : ["jquery"]
}Type: Stream or String
Supply a filepath (can be a glob) or a gulp stream to your config file that lists all your paths, shims and maps.
amdOptimize.src("index", {
configFile : "src/scripts/require_config.js"
});
amdOptimize.src("index", {
configFile : gulp.src("src/scripts/require_config.coffee").pipe(coffee())
});Type: Boolean
Default: false
If true it will trace require() dependencies inside of top-level require() or define() calls. Usually, these nested dependencies are considered dynamic or runtime calls, so it's disabled by default.
Would trace both router and controllers/home:
define("router", [], function () {
return {
"/home" : function () {
require(["controllers/home"]);
},
...
}
})Type: Boolean
Default: false
If true all files that you have declared a shim for and don't have a proper define() call will be wrapped in a define() call.
// Original
var test = "Test";
// Output
define("test", [], function () {
var test = "Test";
return test;
});
// Shim config
shim : {
test : {
exports : "test"
}
}Type: Boolean
Default: false
If true all files that you combine will not be altered from the source, should be used for outputted files to match the original source file, good for debugging and inline sourcemaps. A good code minifier or uglify will remove comments and strip new lines anyway.
WIP. Subject to change.
amdOptimize.src(
"index",
loader : amdOptimize.loader(
// Used for turning a moduleName into a filepath glob.
function (moduleName) { return "src/scripts/" + moduleName + ".coffee" },
// Returns a transform stream.
function () { return coffee(); }
)
)Same as amdOptimize(), but won't accept an input stream. Instead it will rely on loading the files by itself.
- Check the input stream.
- Look for files with the default loader and
baseUrl. - Look for files with the custom loader and its transform streams.
- Give up.
- gulp-concat: Concat the output files. Because that's the whole point of module optimization, right?
var concat = require("gulp-concat");
gulp.src("src/scripts/**/*.js")
.pipe(amdOptimize("index"))
.pipe(concat("index.js"))
.pipe(gulp.dest("dist"));- gulp-uglify: Minify the output files.
var uglify = require("gulp-uglify");
gulp.src("src/scripts/**/*.js")
.pipe(amdOptimize("index"))
.pipe(concat("index.js"))
.pipe(uglify())
.pipe(gulp.dest("dist"));- gulp-coffee: Precompile CoffeeScript source files. Or any other language that compiles to JS.
var coffee = require("gulp-coffee");
gulp.src("src/scripts/**/*.coffee")
.pipe(coffee())
.pipe(amdOptimize("index"))
.pipe(concat("index.js"))
.pipe(gulp.dest("dist"));- gulp-if: Conditionally pipe files through a transform stream. Useful for CoffeeScript precompilation.
var gif = require("gulp-if");
gulp.src("src/scripts/**/*.{coffee,js}")
.pipe(gif(function (file) { return path.extname(file) == ".coffee"; }, coffee()))
.pipe(amdOptimize("index"))
.pipe(concat("index.js"))
.pipe(gulp.dest("dist"));- event-stream, gulp-order: Add files before or after
var eventStream = require("event-stream");
var order = require("gulp-order");
eventStream.merge(
gulp.src("bower_components/almond/almond.js"),
gulp.src(amdOptimize("index"))
.pipe(concat("index.js"))
)
.pipe(order(["**/almond.js", "**/index.js"]))
.pipe(concat("index.js"))
.pipe(gulp.dest("dist"));- No RequireJS plugins. Except for the
textplugin. - No
excludeorincludeconfiguration. - No circular dependencies
- Install npm dev dependencies
npm install - Install gulp globally
npm install -g gulp - Run
