Learn through a guided exercise with a concrete checkpoint.
Work through this exercise in order. The checkpoint tells you what to observe before you move to the detailed reference.
1. Open the deployed LiveBoard application linked from its repository and sign in with two separate accounts. This exercise requires a running backend, PostgreSQL, and a collaboration session; it is not a standalone browser demo.
2. Create a canvas as its owner and add the second account as a member. Open the same canvas in separate browser sessions.
3. Create a rectangle and drag it while watching the second session. Stop dragging to commit the edit. Then change its color and invoke undo.
4. Checkpoint: both sessions should settle on the same shape state after the commit and shared undo. Refresh the second session to check that the saved state agrees with what collaboration displayed.
