Primeout

Create a promise with a timeout.

npm install primeout

const primeout = require('primeout')

// Will reject if the `connectToDb()` promise does
// not respond within 30 seconds.
primeout('30 seconds', connectToDb()).then((db) => {
  ...
}).catch((err) => {
  ...
})

Examples

All of these examples assume that connect() returns a promise.

// Set a timeout of 5 seconds
primeout(5000, connect())
  .then(...)
  .catch(...)

// Set a timeout of 5 minutes
primeout('5m', connect())
  .then(...)
  .catch(...)

// Set a timeout that rejects if the
// promise is not resolved or rejected
// before the next event loop.
primeout(0, connect())
  .then(...)
  .catch(...)

For a clear-cut explanation of that last example (especially if you're new to node.js) see Understanding the node.js event loop.
