fs-promise-polyfill

fs API promise

fs API promise file

  const fs = require('fs-promise-polyfill')
  fs.readFile(path).then(data => {
    console.log(data)
  })

Even a synchronous API, it does not need to use try-catch

  // return the data or instanceof Error
  const data = fs.readFileSync(path, 'utf-8')
  console.log(data instanceof Error)
  console.log(data)
  // or
  // return the data or null
  const data = fs.readFileSyncNull(path, 'utf-8')
  console.log(data)
  // or
  fs.readFileSyncP(path, 'utf-8').then(data => {
    console.log(data)
  })
