For a while, I was involved into development of a document workflow management-as-a-service system. The client app was created using AngularJS and I was to decide on the best option for its internalization (i18n) and localization (l10n). However, the service had a rather complex UI with plenty of messages to be translated and transferred between the server and the client. Therefore, I was concerned about the impact of client-side translation on performance.
In this post, I explore this in detail and suggest an approach that accelerates performance of AngularJS internationalization.
