Client Commands and Server Messages

This section describes the WebSocket commands that clients can send to the Pomodoro server and the messages that the server sends to clients during a Pomodoro session.

Message Format

Both client commands (sent to the server) and server messages (sent to the client) use the JSON format. The structure of these messages are described in the sections below.

Client Commands

Clients communicate with the server by sending JSON-encoded commands. Each command must include a command field specifying the action to perform. Here are the available commands:

Command	Action	Example Sent by Client
`start`	Starts a new Pomodoro session	`{"command": "start"}`
`pause`	Pauses the current session	`{"command": "pause"}`
`resume`	Resumes a paused session	`{"command": "resume"}`
`reset`	Stops and resets the current session	`{"command": "reset"}`

Optional Start Parameters

The Start-Command may contain an optional Pomodoro-Config, which allows you to customize the length of the work session, short break, long break, and the number of sessions. If no configuration is provided, the server will use default values.

Example:

{
    command: "start",
    config: {
        "work": 10,          // Length of the work session in seconds
        "shortBreak": 5,     // Length of the short break in seconds
        "longBreak": 10,     // Length of the long break in seconds
        "sessions": 2        // Number of total sessions
    }
}

Server Messages

The server sends JSON-encoded messages to all connected clients to update them on the current state of the Pomodoro session. These messages contain the following fields:

mode: Indicates the current phase of the Pomodoro session ("Work", "ShortBreak", "LongBreak", or "none" if no session is running).
session: The current session number (e.g., 1 for the first work session).
max_session: The total number of sessions for the current Pomodoro cycle (e.g., 4 if the cycle consists of 4 work/break sessions).
time_left: The remaining time for the current mode, in seconds (e.g., 900 for 15 minutes).

Message Type	Sent by Server	Example
Welcome Message	Upon initial client connection	`{"mode": "none", "session": 0, "max_session": 0, "time_left": 0}`
Session Update	Periodically during a session	`{"mode": "Work", "session": 1, "max_session": 4, "time_left": 900}`
Session End/Reset	After session completes or is reset	`{"mode": "none", "session": 0, "max_session": 0, "time_left": 0}`

Testing

docker run --rm -d --name pomodoro-client -v $PWD:/usr/share/nginx/html/ -p 8081:80 nginx
go run .
