The LiveKit egress worker interactions are proxied through the backend for
security reasons. Allowing clients to directly use tokens with sufficient
grants to start recordings could lead to misuse, enabling users to spam the
egress worker API and potentially initiate a DDOS attack on the egress
service. To prevent this, only users with room-specific privileges can
initiate recordings.
We make sure only one recording at the time can be made on a room.
The requested recording mode is stored so it can be referenced later when
the recording is saved, triggering a callback action as needed.
A feature flag was also introduced for this capability; while this is a simple
approach, a more robust system for managing feature flags could be valuable
long-term. For now, KISS (Keep It Simple, Stupid) applies.
The viewset endpoints were designed to be as straightforward as possible—
let me know if anything can be improved.
Implements routes to manage recordings within rooms, following the patterns
established in Impress. The viewset exposes targeted endpoints rather than
full CRUD operations, with recordings being created (soon) through
room-specific routes (e.g. room/123/start-recording).
The implementation draws from @sampaccoud's initial work and advices.
Review focus areas:
- Permission implementation choices
- Serializer design and structure

Switched to using query parameters instead of GET requests, enabling the
inclusion of additional parameters when calling the create endpoint via POST.
Simplified the access token generation process by removing redundant calls to
`with_identity` and consolidating token generation steps. This streamlines the
method flow by preparing all necessary data before generating the access token.
Recent updates of dev/ruff and dev/pylint dependencies led
to new linting warnings.
Pylint 3.2.0 introduced a new check `possibly-used-before-assignment`,
which ensures variables are defined regardless of conditional statements.
Some if/else branches were missing defaults. These have been fixed.
The Pylint job was failing due to those TODO items. In our make lint
command sequence, Pylint runs first. If it fails, Ruff won't run,
which is quite inconvenient.
I've extracted those TODOs into an issue for further review.
Quick and dirty approach. It works, that's essential.
Frontend can pass a desired username for the user. This would
be the name displayed in the room to other participants.
Usernames don't need to be unique, but user identities do
If no username is passed, API will fall back to a default username.
Why? This serves as a security mechanism. If the API is called
incorrectly by a client, it maintains the previous behavior.
It seems appropriate that backend owns the responsability of knowing any
information/configurations of the LiveKit server. Then, it shares those
with the frontend.
Please see my previous commit to understand why environment variables are
not appropriate for deployment in several remove environments.
As of today, the LiveKit server URL is the only configuration exposed
dynamically to the frontend. Thus, it doesn't justify adding a new route
to the API, responsible for exposing configurations (e.g. /configuration).
As the frontend needs to call the backend when it wants to initiate a new
webconference room, let's pass the server URL when retrieving the room's token.
It is relevant, to get both the room location and the keys to open the room in
the same call.
I prefered to be pragmatic, if the need appears any soon, I would refactor
these parts.
I have updated all references of "Impress" to "Meet".
Migrations were manually updated and not regenerated. Never-mind,
they all will be squashed before the first release.
I have also searched for reference to "Magnify", and replaced them
by "Meet".
While updating the backend sources, I have also fixed other parts of
the project, namely:
- Compose file
- Github documentation and CI
- Makefile commands
Introduce CRUD API endpoints for the Rooms and ResourceAccess models.
The code follows the Magnify logic, with the exception that token generation
has been removed and replaced by a TODO item with a mocked value.
Proper integration of LiveKit will be added in future commits.
With the removal of group logic, some complex query sets can be simplified.
Previously, we checked for both direct and indirect access to a room.
Indirect access meant a room was shared with a group, and the user was a
member of that group. I haven’t simplified those query set, as I preferred
isolate changes in dedicated commits.
Additionally, all previous tests are still passing, although tests related
to groups have been removed.
This commit introduces a boilerplate inspired by https://github.com/numerique-gouv/impress.
The code has been cleaned to remove unnecessary Impress logic and dependencies.
Changes made:
- Removed Minio, WebRTC, and create bucket from the stack.
- Removed the Next.js frontend (it will be replaced by Vite).
- Cleaned up impress-specific backend logics.
The whole stack remains functional:
- All tests pass.
- Linter checks pass.
- Agent Connexion sources are already set-up.
Why clear out the code?
To adhere to the KISS principle, we aim to maintain a minimalist codebase. Cloning Impress
allowed us to quickly inherit its code quality tools and deployment configurations for staging,
pre-production, and production environments.
What’s broken?
- The tsclient is not functional anymore.
- Some make commands need to be fixed.
- Helm sources are outdated.
- Naming across the project sources are inconsistent (impress, visio, etc.)
- CI is not configured properly.
This list might be incomplete. Let's grind it.
