fix(browse): externalize @ngrok/ngrok so Node server bundle builds on Windows#1019

build-node-server.sh fails on Windows with:
error: cannot write multiple output files without an output directory
Root cause: server.ts has two `await import('@ngrok/ngrok')` calls
(lines 1588 and 2368), which makes bun emit a separate chunk for the
ngrok module. Combined with `--outfile` (single-file output), bun
refuses to write the multiple files.
Fix: pass `--external "@ngrok/ngrok"` to the bun build invocation,
matching the pattern already used for playwright, playwright-core,
diff, and bun:sqlite. The dynamic import then resolves at runtime
via node_modules instead of being bundled.
Verified on Windows 11 / Git Bash / bun 1.3.11:
Bundled 25 modules in 52ms
server-node.mjs 0.33 MB (entry point)
Restores /gstack-browse, /gstack-canary, /gstack-pair-agent,
/gstack-open-gstack-browser, /gstack-setup-browser-cookies,
and /gstack-design-review on Windows.

Closing — duplicate of several PRs fixing the same @ngrok/ngrok Windows build issue. We'll pick the best approach and merge separately. Thank you for the contribution! |

… Windows @ngrok/ngrok has a native .node addon that causes `bun build --outfile` to fail with "cannot write multiple output files without an output directory". Externalize it alongside the existing runtime deps (playwright, diff, bun:sqlite), matching the exact pattern used for every other dynamic import in server.ts. Adds a policy comment explaining when to extend the externals list so the next native dep doesn't repeat this failure. Two community contributors independently converged on this fix: - @tomasmontbrun-hash (#1019) - @scarson (#1013) Also fixes issues #1010 and #960.

Thanks @tomasmontbrun-hash — landed your fix in #1024 (v0.18.0.1) along with the CI error-swallowing fix that let this slip through in the first place. Your diagnosis and one-line fix were spot on. Closing in favor of #1024, which credits you in the CHANGELOG and commit body. Thanks again for tracking this down on a fresh Windows install — this was breaking |

Summary
browse/scripts/build-node-server.shfails on a fresh install on Windows with:This breaks the browser-related skills on Windows after
./setup:/browse,/canary,/pair-agent,/open-gstack-browser,/setup-browser-cookies, and/design-review(all of which rely onserver-node.mjs).Root cause
browse/src/server.tshas twoawait import('@ngrok/ngrok')calls (around lines 1588 and 2368). Bun treats these dynamic imports as a code-splitting signal and wants to emit a separate chunk for@ngrok/ngrok. Combined with--outfile(single-file output, used by the script), bun refuses with the "cannot write multiple output files without an output directory" error.The other skipped externals in the same
bun buildinvocation (playwright,playwright-core,diff,bun:sqlite) use exactly the pattern needed here.Fix
Add
--external "@ngrok/ngrok"to thebun buildinvocation. The dynamic import then resolves at runtime vianode_modules/@ngrok/ngrokinstead of being bundled, no chunks emitted, single-file output succeeds.@ngrok/ngrokis already declared inpackage.json("^1.7.0"), so it's reachable at runtime under Node.Verification
Confirmed
browse.exethen launches the bundled server ([browse] Starting server...→ command list) on:Test plan
./setup --host claudeon a fresh Windows install — expect no build error./browse goto …command after install — expect server to start and respond.
