Webpage-text translation on client-side (without internet connectivity)

Question

I need a web-application to be translated from English to Portuguese. Since the servers on which this application runs have no internet access, is there a way to achieve this without using a 3rd Party API. Is there a JS Library that can translate from say Language A to Language B on the client side ?

Answer 1

You can definitely use Java Script for that.

The library well known for translations is the i18next

You can integrate with jQuery, but I strongly recommend you using something like AngularJS or Mustache for customise your template.

If you choose use AngularJS you can have a different JSON file with your expressions, and depending on the language you are navigating, loads a different JSON file, like:

en.json, es.json, pt.json

You can use JS Cookies for saving the language as same you would do with any backend language.

Mustache is used to create templates front-side with double brackets {{custom_text}}. AngularJS uses the same idea.

The only issue if you want to use AJAX. Read more about Google Chrome --allow-file-access-from-files disabled for Chrome Beta 8
