DevCollab v2

DevCollab is a FastAPI + PyQt6 collaborative workspace for small teams. The backend owns authentication, permissions, room membership and real-time events; the desktop client is a focused collaboration UI.

• Numeric database IDs are no longer a join credential.
• Every room gets a cryptographically generated invite code such as AB12C-9XZ8Q.
• Joining requires both the invite code and the room password.
• Room passwords are bcrypt-hashed; plaintext room passwords are never stored.
• Users have persistent room membership after joining, so guessing a numeric ID does not grant access.
• Room creators can delete their entire room. Joined members appear in Joined rooms automatically and can open the room without entering the invite code again.
• Room owners can search the user database and add existing users directly to a room.
• Owners can leave a room too; ownership transfers to the longest-standing remaining member. A solo owner must delete the room instead.

• The task creator or a room admin can delete that task.
• The backend enforces the rule; changing the desktop client cannot bypass it.
• The room owner is the default admin. If ownership is transferred, the new owner becomes the admin.
• Like/dislike and status changes still work for room members.

• Every task now has a discussion area.
• Any room member can add an opinion/comment.
• Comments support independent likes and dislikes per user.
• Comment creators can delete their own comments.
• Comment activity is synchronized live over WebSockets.

• Dark visual system with reusable cards, typography and accent styles.
• Home dashboard split into Your rooms and Joined rooms.
• Room-owner user search with one-click member invitations from the existing user database.
• Generated invite code shown clearly in a room.
• Two-pane room layout: tasks on the left, selected task + discussion on the right.
• Cleaner task cards with creator, timestamp, reactions and status.
• Simple DevCollab DC brand mark integrated into the interface.

You need two terminals.

cd backend
pip install -r requirements.txt
uvicorn main:app --host 127.0.0.1 --port 8000

The backend creates devcollab.db automatically.

In another terminal:

cd client
pip install -r requirements.txt
python main.py
