Create a stream that immediately emits the specified Error. Sugary wrapper around from2.
Useful when you want to create a Stream for unit testing your error handlers.
const from = require('from-error');
const through = require('through2');
from(new Error('Test error'))
.on('error', err => {
// Handle the error here
})
.on('data', () => {
// This will never run
})
.on('end', () => {
// This will never run
})
.on('close', () => {
// This will emit when the stream is done
});npm test
