concat-stream with a promise interface
npm install concat-stream-pconcat-stream is commitment-phobic so I made a promise interface wrapper which accepts all of concat-stream's options. See its documentation first.
npm install concat-stream-p
``JavaScript
var fs = require('fs')
var concat = require('concat-stream-p')
var readStream = fs.createReadStream('cat.png')
readStream.on('error', handleError)
readStream.pipe(concat()).then(function (imageBuffer) {
// imageBuffer is all of cat.png as a node.js Buffer
})
function handleError(err) {
// handle your error appropriately here, e.g.:
console.error(err) // print the error to STDERR
process.exit(1) // exit program with non-zero exit code
}
`
`js`
var concat = require('concat-stream-p')
Returns a stream.Writable` that's also a promise of all of the data that
was written to the stream.
