Migrating critical apps to React
summary
Migration at PayPal Send Money moves a legacy Dust/RequireJS/Backbone stack to React and webpack, converting property files to JSON and adding an i18n mixin so server rendered content still works. Experimentation with Ember and React leads to swapping RequireJS for webpack in two days, enabling npm modules, JSX and Babel. A staged rewrite ramps from 5% to 100% US traffic while the migrated notes widget lands as a minimal PR and improves perceived speed and metrics.
