app/helpers Code that can be used from views, i.e. common operations
app/lib Code that doesn’t fit in the other categories
app/models Code that represents data entities
app/serializers Code that generates JSON from models
app/services Complex logical operations involving multiple models
app/views Templates for generating HTML or other output
app/workers Code that executes outside the request-response cycle
spec Automated test suite

JavaScript

Path Description
app/javascript/mastodon Code for the multi-column React.js application

Localizations

Path Description
