Open Code web as batch connect app

fangpingmu · May 2, 2026, 7:44pm

Is it possible to add Open Code web ( Web | OpenCode ) as batch connect app? In script.sh.erb, I have tried:

opencode web --hostname 0.0.0.0 --port ${port}
opencode web --hostname 0.0.0.0 --port ${port} --cors https://my.ood.host/rnode/${host}/${port}

They are not working.

I’m an not familiar with that product, so I’m not sure.

What’s the error you’re seeing?

There is no error. It is blank screen.

### Issue for this PR Closes #13847 ### Type of change - [ ] Bug fix -… [x] New feature - [ ] Refactor / code improvement - [x] Documentation ### What does this PR do? This adds native `basePath` support for the OpenCode server and web UI so it can be served cleanly from a subpath such as `/opencode/` instead of assuming `/`. On the server side, requests can now arrive either with the configured prefix still present or already stripped by a reverse proxy, and both cases resolve to the same internal route tree. On the frontend side, the app shell now emits relative asset URLs, the HTML response exposes the effective mount path, and the browser uses that path when building API, SSE, WebSocket, and router URLs. These changes work because they keep the existing API paths unchanged internally and treat the subpath as a transport/runtime concern at the server boundary and browser bootstrap boundary. That makes the legacy Hono backend, the experimental HttpApi backend, and the built app all agree on the same effective mount path. ### How did you verify your code works? - Ran `npm exec -- bun test test/server/base-path.test.ts test/cli/network.test.ts test/server/httpapi-ui.test.ts` in `packages/opencode` - Ran `npm exec -- bun typecheck` in `packages/opencode` - Ran `npm exec -- bun test --preload ./happydom.ts ./src/utils/base-path.test.ts ./src/index-shell.test.ts ./src/vite-config.test.ts` in `packages/app` - Ran `npm exec -- bun typecheck` in `packages/app` - Ran `npm exec -- bun run build` in `packages/app` - Confirmed the emitted `packages/app/dist/index.html` uses relative asset URLs such as `./assets/...` - Build "localcode" based on this commit on docker and execute the command "opencode web --hostname 127.0.0.1 --port "4096" --base-path /opencode" and put a NGINX on front with: ``` location /opencode/ { proxy_pass http://127.0.0.1:4096; proxy_http_version 1.1; proxy_set_header Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade; } ``` ### Screenshots / recordings (See the URL on browser, that starts with "http://localhost/opencode") <img width="1920" height="1077" alt="image" src="https://github.com/user-attachments/assets/c17d2822-238c-4270-ac13-28c9b071511a" /> <img width="1920" height="1077" alt="image" src="https://github.com/user-attachments/assets/bea5260c-56ce-4349-9e54-02fabb6a382f" /> <img width="1920" height="1077" alt="image" src="https://github.com/user-attachments/assets/f767296c-4464-43ec-bb95-a1a79696c420" /> Don't have visual UI changes; this PR changes mount-path, assets, routing and request behavior. ### Checklist - [x] I have tested my changes locally - [x] I have not included unrelated changes in this PR

I believe that this is the culprit. I will test it again when open code supports subpath.

OK that could be it. Even so, if you open your developer tools and see the network traffic that is or isn’t happening that could help too.
