Developing with Elm in a large application
summary
Unipos runs on Elm with 70k lines of front-end code across about 30 pages and is maintained by 6 front-end engineers. Elm delivers no runtime exceptions, immutable data, and the Elm Architecture plus ports for JS interop, and compiler errors (improved in v0.19.19) turn into fast, reliable refactors. Pain points include awkward module and model splitting as the app grows, extra boilerplate for component decomposition, and a nontrivial learning curve for functional patterns and design tradeoffs.
