ez-localize

Localizing an application should be easy, not hard. ez-localize makes it ridiculously simple.

Usage

Step 1: Use T() to wrap strings

Just replace:

console.log("Hello world!");

With:

console.log(T("Hello world!"));

Or use ES6 tagged templates:

console.log(T`Hello world!')

Step 2: Extract strings from your application

var extractor = require('ez-localize/extractor');

extractor.updateLocalizationFile("index.js", "localizations.json", {}, function() { console.log("done!")})

Step 3: Create a localizer and make global

var ezlocalize = require('ez-localize');
var localizations = require('localizations.json');

var localizer = new ezlocalize.Localizer(localizations, "en")
localizer.makeGlobal();

Step 4: Edit localizations.json to add other languages and translations

You're done!

Advanced

String substitution:

console.log(T("This works {0}%!", 100);

console.log(T`This works ${100}%!`);

React-style substitution:

console.log(T("This works {0}%!", { x: 10 });

will create array of ["This works ", { x: 10 }, "%!"]

It handles Handlebars too:

var options = { extensions: ['.js'], transform: [hbsfy] };
extractor.updateLocalizationsupdateLocalizationFile("index.js", "localizations.json", options, function() { console.log("done!")})

To register a T helper:

var ezlocalize = require('ez-localize');
var handlebars = require("hbsfy/runtime");
var localizations = require('localizations.json');

var localizer = new ezlocalize.Localizer(localizations, "en")
localizer.makeGlobal(handlebars);

Only relative requires are included by default. To include another module, pass externalModules to options, an optional list of external modules to include

Localizing a JSON object

To localize the strings inside a JSON object (plain javascript object), use require('ez-localize/lib/JsonLocalizer`)
