We Started Using Webpack and It Took A While

" summary

Etsy migrates from Builda to Webpack and runs into concrete problems: an initial half hour first build that consumes 20 GB RAM, slow dev servers that keep everything in memory, and scaling a mono-repo by splitting into 11 regions and writing Kevin plugin to manage multiple Webpack instances. Localization into 15 languages requires clever placeholder + find-and-replace to hit <5-minute production builds. A subtle 4 ms timeout bug in bootstrap code delays launch by months until it’s measured and fixed.
