How to rewrite enterprise application into React ...
summary
A Jira-family app migrates to React and Redux over a year and ships a working rewrite that fixes performance and maintainability problems. Migration touches 90k LOC, >1,000 components and more than 200 epics and moves the codebase to Flow types, selector memoization, virtualization and per-app probes to reduce selector waterfalls. Tooling includes ESLint rules, IDE generators, Storybook and an ownership board and the standardized Tangerine initiative is open sourced to scale the approach.
