Steps to add translations to Raxa-JSS module using the i18n library:

Copy the i18n library to the lib folder.
Link to the library : https://github.com/Raxa/Ext.i18n.Bundle
In the app.js (for each module) give path mapping as follows:

Ext.Loader.setConfig({
enabled: true,
paths: {
'Ext.i18n': 'lib/i18n' //Mention the relevant path to the i18n library over here.
}
});
Instantiate an instance of i18n bundle to be usable across a module as follows in the app.js of the respective module.
(read convention, where bundle is name of the .properties file; lang is locale; path is filepath). So the file should be called a default RaxaEmr.properties and a lang version RaxaEmr_en-US.properties (say for en-US) . For registration it will be RaxaEmr.Registration_en-US.properties

Code to instantiate:

Ext.require('Ext.i18n.Bundle', function(){
Ext.i18n.appBundle = Ext.create('Ext.i18n.Bundle',{
bundle: 'RaxaEmr',
lang: 'en-US',
path: 'app/view', //For login
noCache: true
});
});
Suppose you wanted to change the 'Please login' text from Login.js main app view. You'd replace the title for the fieldset as follows:
Ext.i18n.appBundle.getMsg('RaxaEmr.view.Login.title'),
In the RaxaEmr_en-US.properties file, the mapping would be like this:
RaxaEmr.view.Login.title=Please Login
You can add comments to the .properties file by preceding the comment with a #
eg. # This is a comment.
