Runnable example bundle
Download the verified 7.2.0 source ZIP. It includes four chat apps and one WebRTC app, exact IOSignal dependencies, lockfiles, and regression tests. The upstream source is iosignal-examples; GitHub main can change independently of this bundle.
Install and run
Prepare Node.js 22.16 or later and npm. Extract the ZIP, then:
cd iosignal-examples-7.2.0/iosignal_vanilla-chat
npm ci
npm ls iosignal
npm run dev
Confirm that npm ls reports 7.2.0. npm ci follows the included lockfile. If you already opened the example directory in your terminal, omit cd.
Alternatively, clone the upstream repository and record its commit and installed version:
git clone https://github.com/remocons/iosignal-examples.git
cd iosignal-examples/iosignal_vanilla-chat
git rev-parse HEAD
npm ci
npm ls iosignal
npm run dev
Confirm success
Open http://localhost:5175 in two tabs on the same computer. Wait for both to show ready and a CID. Send a message and confirm it appears in the other tab. The channel is openchat and the server is ws://localhost:7779. Stop with Ctrl+C.
npm run dev starts both the web and messaging servers. localhost refers to the device running the browser; see connection environments before using another phone or PC.
Choose an example
| Folder | Web port | WebSocket port | Use |
|---|---|---|---|
iosignal_vanilla-chat | 5175 | 7779 | Framework-free starting point |
iosignal_react-chat | 5173 | 7777 | React lifecycle |
iosignal_svelte-chat | 5174 | 7778 | Svelte state and lifecycle |
iosignal_vanilla-chat_CDN | 5176 | 7780 | CDN browser import |
iosignal_webrtc | 5180 | 7781 | Video-call signaling |
Run the same installation/development commands in each folder. Servers are independent: open two tabs of the same example to chat. The CDN app still requires local npm dependencies and internet access for its browser import.
For Vanilla, read package.json / package-lock.json, vite.config.js (ports), main.js (client flow), index.html (UI), and server.js (standalone signaling).
Build and preview
Stop the development server. In terminal 1 run npm run server. In terminal 2:
npm run build
npm run preview
Open the printed preview web URL in two tabs. Build and preview do not start the IOSignal server. Stop both terminals with Ctrl+C. External deployment requires a reachable server and TLS configuration.
Verified baseline
On 2026-10-18, all five apps built with 7.2.0. Four chat tests passed two-client bidirectional messaging and reconnection. Five WebRTC integration tests passed.
After running npm ci in each app, reproduce browser tests from iosignal_webrtc:
npx playwright install chromium
npm test
npm run test:chats
Alternatively set CHROME_PATH to an installed Chrome executable. Tests start and stop local servers; CDN needs internet. WebRTC uses simulated capture devices. Physical boards, real capture devices, Safari/iOS, different internet networks, and TURN relay are outside this verification.
Continue with chat flow, troubleshooting, or choose your path.
