SDK mode

EC can be build in sdk mode. This will result in a compiled js file that can be imported in very simple webapps.

It allows to use matrixRTC in combination with livekit without relying on element call.

This is done by instantiating the call view model and exposing some useful behaviors (observables) and methods.

This folder contains an example index.html file that showcases the sdk in use (hosted on localhost:8123 with a webserver allowing cors (for example npx serve -l 81234 --cors)) as a godot engine HTML export template.

Getting started

To get started run

yarn
yarn build:sdk

in the repository root.

It will create a dist folder containing the compiled js file.

This file needs to be hosted. Locally (via npx serve -l 81234 --cors) or on a remote server.

Now you just need to add the widget to element web via:

/addwidget http://localhost:3000?widgetId=$matrix_widget_id&perParticipantE2EE=true&userId=$matrix_user_id&deviceId=$org.matrix.msc3819.matrix_device_id&baseUrl=$org.matrix.msc4039.matrix_base_url&roomId=$matrix_room_id

Widgets

The sdk mode is particularly interesting to be used in widgets. In widgets you do not need to pay attention to matrix login/cs api ... To create a widget see the example index.html file in this folder. And add it to EW via: /addwidget <widgetUrl> (see url parameters for more details on <widgetUrl>)

url parameters

The url parameters are needed to pass initial data to the widget. They will automatically be used by the matrixRTCSdk to start the postmessage widget api (communication between the client (e.g. Element Web) and the widget)

widgetId = $matrix_widget_id
perParticipantE2EE = true
userId = $matrix_user_id
deviceId = $org.matrix.msc3819.matrix_device_id
baseUrl = $org.matrix.msc4039.matrix_base_url

parentUrl = // will be inserted automatically

Full template use as <widgetUrl>:

http://localhost:3000?widgetId=$matrix_widget_id&perParticipantE2EE=true&userId=$matrix_user_id&deviceId=$org.matrix.msc3819.matrix_device_id&baseUrl=$org.matrix.msc4039.matrix_base_url&roomId=$matrix_room_id

the $ prefixed variables will be replaced by EW on widget instantiation. (e.g. $matrix_user_id -> @user:example.com (url encoding will also be applied automatically by EW) -> %40user%3Aexample.com)
