API

holdUp(fn[, options])

holdUp([fn, args], options)

• fn - function
• args - array of arguments
• options - options may contain:
  • log
  • count
  • time

const holdUp = require('hold-up');
const fn = async (a = 'hello') => {
    throw Error(a);
};

await holdUp(fn);

// reject in a 5 seconds
// [Error: hello]

// with arguments
await holdUp([fn, 'world']);

// reject in a 5 seconds
//[Error: hello]

// when you need to override options,
await holdUp([fn, 'hello'], {
    count: 5,       // default
    time: 1000,     // default
    log: () => {},  // default
});
