attempts

attempts

Try func with different args.

Methods

• attempts.sync(values, fn) ⇒ result / undefined
  Invoke fn with values[n] one by one, until get a truthy return value.

• attempts.async(values, fn) ⇒ Promise (resolved with result / rejected with undefined)
  Invoke fn with values[n] one by one, until get a truthy return value or resolved Promise.

NOTE: Exceptions within fn will be catched & treated as a falsy return, handy for some Node.js API (fs.accessSync, fs.statSync, etc.) throw errors regularly.

Example

Get availiable config:

const attempts = require('attempts')

const readConfig = filename => require(filename)
const possibleConfigs = [
  './config.json',
  './config.default.json'
]

const config = attempts.sync(possibleConfigs, readConfig)
