Devin FoleyandPaperclip 27ab902d3d perf(docker): start the server from a precompiled runtime bundle (#16672)
The production image started the server through the tsx loader, which resolved about 3,100 modules and transpiled about 1,200 workspace TypeScript files on every boot (7.6-20 s before listen on a live instance). A build:runtime step now bundles server/dist/index.js with esbuild, compiling in the workspace packages, and the image starts node server/dist-runtime/index.mjs. Server dependencies stay bare so runtime resolution (including the cloud image's optional peers) is unchanged; each module keeps its original import.meta location; dynamic imports stay split; the entry presents the original dist/index.js as argv[1]. The avatar worker loads through tsx's API when the main thread has no loader, tini runs as a subreaper (-s), and PR CI boots the bundle with scripts/server-boot-smoke.sh.

// Prove two things about the target image's server directory, in order:
//
// 1. The tsx loader, `server/node_modules/tsx/dist/loader.mjs`, still
// resolves. Workers that load workspace TypeScript on demand use it (the
// production `CMD` itself starts the runtime bundle with plain node). That
// path is a symbolic link into the workspace pnpm store, and the `cloud`
// stage's Sentry copy writes into the same `server/node_modules`
// directory, so a copy that removes or shadows the link breaks them.
// 2. The installed `@sentry/node` package resolves, the same way the
// server's own peer-version gate does
// (server/src/peer-version-check.ts). Then print its version.
//
// Exit non-zero, with a clear message on standard error, when either check
// fails. Print only the version string on standard output on success.
//
// Mount this file at a path inside the target image's server directory and
// run it there with `node`, so module resolution walks the same
// `node_modules` tree the running server itself resolves from:
//
// docker run --rm \
// -v "$PWD/scripts/assert-cloud-image-sentry.mjs:/app/server/.ci-sentry-probe.mjs:ro" \
// --entrypoint node <image> /app/server/.ci-sentry-probe.mjs
