Question

I’m using requireJS to load scripts. It has this detail in the docs:

The path that is used for a module name should not include the .js
extension, since the path mapping could be for a directory.

In my app, I map all of my script files in a config path, because they’re dynamically generated at runtime (my scripts start life as things like order.js but become things like order.min.b25a571965d02d9c54871b7636ca1c5e.js (this is a hash of the file contents, for cachebusting purposes).

In some cases, require will add a second .js extension to the end of these paths. Although I generate the dynamic paths on the server side and then populate the config path, I have to then write some extra javascript code to remove the .js extension from the problematic files.

Reading the requireJS docs, I really don’t understand why you’d ever want the path mapping to be used for a directory. Does this mean it’s possible to somehow load an entire directory’s worth of files in one call? I don’t get it.

Does anybody know if it’s possible to just force require to stop adding .js to file paths so I don’t have to hack around it?

thanks.

UPDATE: added some code samples as requested.

This is inside my HTML file (it’s a Scala project so we can’t write these variables directly into a .js file):

foo.js.modules = {
    order               : '@Static("javascripts/order.min.js")',
    reqwest             : 'http://5.foo.appspot.com/js/libs/reqwest',
    bean                : 'http://4.foo.appspot.com/js/libs/bean.min',
    detect              : 'order!http://4.foo.appspot.com/js/detect/detect.js',
    images              : 'order!http://4.foo.appspot.com/js/detect/images.js',
    basicTemplate       : '@Static("javascripts/libs/basicTemplate.min.js")',
    trailExpander       : '@Static("javascripts/libs/trailExpander.min.js")',
    fetchDiscussion     : '@Static("javascripts/libs/fetchDiscussion.min.js")'
    mostPopular         : '@Static("javascripts/libs/mostPopular.min.js")'
};

Then inside my main.js:

requirejs.config({
    paths: foo.js.modules
});

require([foo.js.modules.detect, foo.js.modules.images, "bean"], 
    function(detect, images, bean) {
        // do stuff
});

In the example above, I have to use the string “bean” (which refers to the require path) rather than my direct object (like the others use foo.js.modules.bar) otherwise I get the extra .js appended.

Hope this makes sense.

requirejs’ noext plugin:

Load scripts without appending “.js” extension, useful for dynamic scripts…

Documentation

check the examples folder. All the info you probably need will be inside comments or on the example code itself.

Basic usage

Put the plugins inside the baseUrl folder (usually same folder as the main.js file) or create an alias to the plugin location:

require.config({
    paths : {
        //create alias to plugins (not needed if plugins are on the baseUrl)
        async: 'lib/require/async',
        font: 'lib/require/font',
        goog: 'lib/require/goog',
        image: 'lib/require/image',
        json: 'lib/require/json',
        noext: 'lib/require/noext',
        mdown: 'lib/require/mdown',
        propertyParser : 'lib/require/propertyParser',
        markdownConverter : 'lib/Markdown.Converter'
    }
});

//use plugins as if they were at baseUrl
define([
        'image!awsum.jpg',
        'json!data/foo.json',
        'noext!js/bar.php',
        'mdown!data/lorem_ipsum.md',
        'async!http://maps.google.com/maps/api/js?sensor=false',
        'goog!visualization,1,packages:[corechart,geochart]',
        'goog!search,1',
        'font!google,families:[Tangerine,Cantarell]'
    ], function(awsum, foo, bar, loremIpsum){
        //all dependencies are loaded (including gmaps and other google apis)
    }
);
