every

every checks a whole list of Tasks, Tags, or Spots against one condition. Without it, you’d build the same shape by hand:

// without every
const allEven = shape([fetchUser.result, fetchOrder.result], (results) =>
  results.every((result) => result.id % 2 === 0),
)

// with every
const allEven = every([fetchUser, fetchOrder], (task) => task.result.id % 2 === 0)

Arguments

• list — Tasks, Tags, and Spots to check. A mix is fine.
• predicate — runs once per item. A Task is unwrapped to { result, status, error }; a Tag or Spot, to its value. Must return a boolean.

Returns

Spot<boolean> — true when every item satisfies predicate; false otherwise.

every.status

every.status checks that every Task in a list reached the same status. Without it, you’d write that as the every predicate by hand:

// without every
const allDone = shape([fetchUser.status, fetchOrder.status], (statuses) =>
  statuses.every((status) => status === "done"),
)

// with every
const allDone = every([fetchUser, fetchOrder], (task) => task.status === "done")

// with every.status
const allDone = every.status([fetchUser, fetchOrder], "done")

Arguments

• list — Tasks
• status — the TaskStatus every Task must reach.

Returns

Spot<boolean> — true when every Task reached status; false otherwise.
