Wrapper for repl faking await functionality
npm install await-replrepl.start()await-repl is a simple wrapper for repl.start() that handles lines starting with 'await ' differently: instead of outputting the Promise (or value) it only returns when the Promise is resolved or rejected
javascript
const awaitRepl = require('await-repl');
awaitRepl({
rejectionHandler: (err) => 'Promise rejection: ' + err,
awaitTimeout: 2000
});
`$3
await-repl passes options to #### Additional options
- __rejectionHandler__
function for formatting Promise-rejections
it is passed a
for returning the formatted error to the repl
returning a value is the same as calling callback(returnValue)
- __awaitTimeout__
number of milliseconds before giving up waiting for Promises to be resolved
will act like a Promise-rejection with $3
javascript
> await 42
42
> await Promise.resolve(73)
73
> await new Promise((resolve, reject) => setTimeout(() => resolve('foo'), 1000))
/ After 1 second /
'foo'
>
`#### Previous behavior
javascript
> 42
42
> Promise.resolve(73)
Promise { 73 }
> new Promise((resolve, reject) => setTimeout(() => resolve('foo'), 1000))
Promise { }
>
`$3
Works only for lines __starting__ with 'await ' so things like the following don´t work:
javascript
> let a = await getSomeValueFromDatabase(...)
