This is applicable to almost any piece of software with text in it. When starting your new app, you should make sure you are using a separate language file for the strings in your app. This makes text reusable, and you can change it all in one place.
Once your app gains a community, if you did this, you can also get translators!
With Photon i made the massive mistake of hardcoding everything up until the app became massive, and my PR for un-hardcoding all the strings looks like this:
It was worth it though! Because the community has translated it into 11 languages!
We use I18n at work and it’s great. It’s a bit more cumbersome to write strings but then again I could write a key mapping for that I guess.
