Usage

You can create retry by the API provided by redo-promise. It has 3 parameters:

• promiseFn: the target promise function.
• predicate: function decided whether should be retry.
• opts: retry strategy.

import retry from 'redo-promise';

const fetchUser = id => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      resolve({ id: 'hustcc', name: 'hustcc' });
    }, 10);
  });
};

const fn = retry(fetchUser, r => r.success);

// if the request result is not success, it will retry 5 times.
fn('hustcc').then(user => {}).catch(e => {});

You can customize the retry opts.

import retry from 'redo-promise';

const fn = retry(fetchUser, r => r.success, { delay: 3000, max: 3 });

// if the request result is not success, it will retry 3 times per 3 seconds.
fn('hustcc').then(user => {}).catch(e => {});

opts contains:

• delay: retry delay time in ms, default 1000.
• max: max retry count, default 5.
