Package Exports

bundalo

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bundalo) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Extract/cache/render property files/strings using i18n rules and various rendering engines

Use cases

Initialize bundalo

Call bundalo module with a key that matches your template engine, plus locale information. Currently only dust and none are supported as engines.

var bundalo = require('bundalo');

// couple of configs for later
var config = {
    "contentPath": "locales/", //required
    "fallback": "en-US",       //optional
    "engine": "dust",          //required
    "cache": false             //optional, default is true
};
var config2 = {
    "contentPath": "globals/",
    "fallback": "",
    "engine": "none"
};

//create two bundalo instances. Each has its own cache
var bundle = bundalo(config);
var bundle2 = bundalo(config);

Use bundalo

User wants key/values from some bundle file, corrected for locality, and possibly rendered with some data model

bundler.get({bundle: 'errors/server', locality: 'en-US'}, function bundaloReturn(err, bundle) {
    console.log("what'd we get from bundalo.get?", data, err);
    data.formatDust('otherError', { message: "It was bad" }, function (err, formatted) {
        cb({
            err: data.get('error'),
            otherError: formatted
        });
    });
});

User wants multiple bundles in a single call, to avoid calling bundalo multiple times

bundle.get({'bundle': ['errors/server', 'errors/client'], 'locality': 'en-US',  'model': {'name': 'Will Robinson'}}, function bundaloReturn(err, data) {
    console.log("what'd we get from bundalo.get?", data, err);
    cb({
        'clienterr': data['errors/client'].get('error'),
        'servererr': data['errors/server'].get('error')
    });
});

User wants multiple bundles in a single call, and wants to alias the bundles for easier management upon return

bundle.get('bundle': {
    'server': 'errors/server',
    'client': 'errors/client'
}, 'locality': 'en-US', 'model': {'name': 'Will Robinson'}}, function bundaloReturn(err, bundles) {
    console.log("what'd we get from bundalo.get?", bundles, err);
    cb({
        'clienterr': bundles.client.get('error'),
        'servererr': bundles.server.get('error')
    });
});

Design

When a user first requests a bundle, bundalo will:

fetch the correct file from the file system based on locality
set up a formatter, which will cache its templates on first use
deserialize the rendered properties file via spud
return a JSON data object with the rendered values

Upon subsequent requests for a bundle, the previously cached compiled template will be re-rendered and returned.

Cache will be based upon the filename of the resolved bundle.

Cache is consistent per bundalo instance created.
