build: give the type-check a 4 GB heap (fixes the Amplify deploy) - #339
Merged
Conversation
Amplify's build image runs Node 22 with a ~2 GB default old-space limit. next build compiles, then the TypeScript step runs out of memory at that limit: the project's type-check now peaks at about 2.25 GB. Setting the heap in the build script keeps the fix in the repo rather than in the hosting console. Claude-Session: https://claude.ai/code/session_01TxkiFYtGhZVcNWyxHHEdH6

Amplify's main deploy for 39c629e fails in the build phase after a successful compile:
The build image runs Node 22 with a ~2 GB default old-space limit, and the project's TypeScript check now needs about 2.25 GB. Reproduced locally:
node --max-old-space-size=2048 tsc --noEmitdies the same way; at 4096 it passes with a 2.25 GB peak RSS.This sets
NODE_OPTIONS=--max-old-space-size=4096on thebuildscript so the fix is versioned. Amplify's standard build instance has enough memory for it.yarn buildverified green locally with the change.https://claude.ai/code/session_01TxkiFYtGhZVcNWyxHHEdH6
