fix(api): run the image with Bun's auto-install off - #859
Conversation
The api runner ships bundle/ and no node_modules, so a bare specifier the bundle still carries makes Bun fetch it from npm at runtime. @better-auth/core's guarded optional import of @opentelemetry/api is one: with a network, the first sign-in on a fresh container pulled 639 files; without one, that request stalled while Bun tried the registry. bun --no-install makes the import fail at once, and the guard falls back to the noop telemetry, which is what happens anyway once the fetch fails. The image's CMD and the api start script both carry the flag. The docker-test skill's offline check now signs in as well as hitting health, since the import fires on the first Better Auth call and never at boot, and asserts the install cache stays empty; its dummy env turns the agent route on so that probe can reach it.

- Line 41: Revise the paragraph about the API runner in the Docker deployment
documentation to say that missing imports fail rather than triggering Bun’s
runtime npm auto-install under --no-install. Remove the claims that every import
resolves from the bundle and that the container starts with no network; keep the
separate explanation of native-binary pruning intact.

…ution The callout said the runner resolves every import from the bundle and starts with no network, which the next sentence contradicted: the optional telemetry import is not in the bundle, it fails and falls back. Say what --no-install guarantees instead: resolution never reaches npm, and a specifier the bundle lacks fails rather than being fetched. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>

What
The api Docker image, and the api
startscript behind it, now runbun --no-install bundle/index.mjs. Bun's runtime auto-install is off.Why
Found while testing #857 against the images. The api runner ships
bundle/and nonode_modules, so any bare specifier the bundle still carries makes Bun fetch it from npm at runtime.@better-auth/corehas one: a guarded, optionalimport("@opentelemetry/api")that fires on the first Better Auth call. On a fresh container with a network, the first sign-in pulled 639 files into Bun's install cache; without a network, that request stalled while Bun tried the registry. It is pre-existing (canary's image does the same) and not a bug in Better Auth: the import is meant to fail and fall back to its noop. What was wrong is that the container reached npm at all.With
--no-install, the import fails at once and the guard falls back, which is what happened after the fetch anyway.Proof
Same image, four runs; the control strips the flag from the command:
--network=none)302at once; install cache empty302; 639 files fetched into the cacheThen the golden suite against the images through compose: 59 of 59, and
docker diffon the api container shows nothing under.bun/install/cacheafter the whole run. The host-sidebun run startwith the flag serves health, signs in, and returns the user.The check that missed it
The
docker-testskill's offline self-containment check only hit/api/health, which never reaches the import. It now also signs in and asserts the cache stays empty, with the timing and the failure mode written down, and its dummy env turns the agent route on so the probe can reach it. The Docker docs say why the image runs with the flag.Not covered
Vercel. The function there runs under Vercel's Bun runtime with a command this repo does not control, and its file system is read-only outside
/tmp, so the same import fails and falls back on its own; whether Bun still attempts a registry fetch first is not something I can observe from here. Nothing in the api's behaviour on Vercel changes with this PR.Verification
lint,format,check-types,test(339 pass),build, the strict docs gate and the skills-table check pass. No UI, so no browser pass beyond the suite's own page tests.🤖 Generated with Claude Code
