debug

debug returns a Task that prints state of Tasks, Tags, and Spots to the console — grouped per target. Without it, you’d write that Task by hand and wrap every read in optional:

createTask({
  name: "debug",
  run: {
    context: {
      auth: {
        status: auth.status,
        result: optional(auth.result),
        error: optional(auth.error),
      },
      userId: optional(userId.value),
    },
    fn: (ctx) => {
      console.group("[Task]: auth")
      console.info(ctx.auth)
      console.groupEnd()
      console.group("[Tag]: userId")
      console.info(ctx.userId)
      console.groupEnd()
    },
  },
})

debug(auth, userId)

Console output

▾ [coda] debug
