Edrys is an open-source app that helps you teach remotely.

✨ Features

• Live Classrooms: Click on a student to talk to them, or create rooms and drag students in & out
• Remote Labs: Allow students to interact with your real lab equipment remotely & asynchronously
• Modular: Build your class by combining Modules or make your own with an easy real-time API
• Easy to start: Download and run to start, no databases or any other dependencies to set up
• Privacy-friendly: Passwordless auth with minimal student PII stored
• Fast & Modern: Based on Deno and Vue with a deliberately small codebase
• Free and Open Source, forever: No paywalled features or lock-in

📸 Screenshots

• Classes dashboard: Select what class to enter or create as many as needed

• Teacher class dashboard: Teachers get an overview of all rooms and can move students around to chat

• Student class view: Students see their current room and are able to interact with others in the room

• Class settings: Teachers can manage memberships, modules, and more to customize their class

💡 Use cases

• Live online teaching: One to one, one to many, and many to many live classrooms
• Remote Labs: Allow students to access and control live equipment remotely (eg. remote Arduino fleet)
• Flipped classrooms and blended learning: Create modules to deliver virtually any content asynchronously
• Group coursework: Dynamic breakout rooms and easy jumping between rooms
• Automated Grading: Use Stations to securely auto-grade student submissions into your LMS

With modular architecture anything is possible. A whiteboard, a discussion forum, polls, or even remote Arduino programming, are all easily encapsulated into shareable modules (explore Edrys modules on GitHub).

edrys's Issues

Edrys.org is down which affects all modules

Dear @edrysorg / Adam ... I hope your are well, edrys.org is down ... which would not be such a big deal, but the github page refers to it and I have not the rights to change it ... unfortunately all edrys.js sources cannot be loaded anymore which damages all modules ... could you grant me some more rights or change this in the settings yourself?

Thanks a lot ... André

npm WARN deprecated [email protected]: core-js@<3.23.3 is no longer maintained and not recommended for usage due to the number of issues. Because of the V8 engine whims, feature detection in old core-js versions could cause a slowdown up to 100x even if nothing is polyfilled. Some versions have web compatibility issues. Please, upgrade your dependencies to the actual version of core-js.

[Request]Resize Modules

Hi is there a possibility to resize Modules?

Edrys electron

Hi.
Could you make an Edrys-electron like app?
Like this dev did for jitsi-meet?
https://github.com/jitsi/jitsi-meet-electron
Perhaps you can ask his help for an Edrys-electron...

Disconnected stations

Hello @edrysorg I think there is a general problem, that somehow detaches the station. Here are the steps to repeat this bug:

1. Add a module to a classroom, maybe the Markdown-module
2. Open the station
3. Move your User to the station
4. Change some parts within the configuration
5. Reload the station ...

The station sees itself and sometimes also the users, but on the other side, the station does not appear ...

Here is a terminal output:

Within the browser I get the following error:

The connection to http://localhost:8000/data/readLiveClass/Nxb0Hrr76mz2J75X54-ur?displayName=Teacher+&jwt=eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiJ3QHcuZGUiLCJpYXQiOjE2NzY2MjI5MzU0MDMsImV4cCI6MTY3OTIxNDkzNTQwM30.sqHPHIhubJutvcfm6qM9mwfSYyMie8RPJ5ZXtdOuXFVa_vOWA3pr4i3q3rb6u1_Er3uNe4jwNH1Gdw2pwKMTuQ was interrupted while the page was loading.

I think one reason is, if a station is opened, it is always associated to a teacher. While reloading, all students and teachers are move back to the lobby. Also the teacher that is associated to the station, even if it is not directly within the room, but only if he opens the station ...

Yjs - connector/privider for edrys

Maybe the edrys publish-subscibe module could be used as an connector/provider for Yjs? This way, it would be possible to make use of all collaborative projects (also for the monaco-editor) ...
