npm install go-for-it
const go = require('go-for-it')
const toUpper = async string => {
if (string === 'invalid') throw Error('Invalid input')
return string.toUpperCase()
}
const errorHandler = () => { console.log('There has been an error. I\'ll handle it.') }
const print = console.log
const foo = async input => {
const [err, value] = await go(toUpper(input))
if (err) return errorHandler(err)
print(value)
}
// Works normally.
foo('gunar')
// "GUNAR"
// Business Logic Error gets handled by errorHandler().
foo('invalid')
// "There has been an error. I'll handle it."
// Runtime Exceptions DO NOT get handled by errorHandler(),
foo(555555).catch(e => {
// but can be caught.
console.log(e)
// TypeError: string.toUpperCase is not a function
})
