A developer check of what webxdc apps can use

What it does

Test Webxdc is a tool for app developers. It runs a series of checks against the webxdc API (updates, realtime channels, sending to the chat, file import) and against browser features and the sandbox, and shows the results in three tabs. It tells a developer what works in a given messenger before they build on it.

How to use it

  1. Open the app; the checks run by themselves.
  2. Read the results on the Webxdc, Web API and Sandbox tabs.
  3. Use the buttons to try sending to the chat or the realtime channel.
  4. Open it on two devices to see updates and realtime data arrive.

Known issues

Realtime channel data never arrives on the other device (widget)
Ada and Ben both pressed Join on the realtime channel, then Send Data (Ada twice, Ben once). Each side shows its own SENT line, but no RECEIVED line appeared on the other side within 8–12 s, in three recordings. The widget sends realtime data as encrypted to-device messages (src/room.ts joinRealtime: api.sendToDevice(REALTIME_TYPE, true, …).catch(() => undefined)), so a refusal by Element or a missing to-device capability is swallowed silently.
