Convert node.js Streams into Promises
$ npm install sprom
sprom.end(request(url).pipe(fs.createWriteStream('file.json')))
.then(function () {
console.log('Successfully wrote file');
}, function (err) {
console.error('Failed to write file');
console.error(err.stack || err.message || err);
});
sprom(request(url))
.then(function (body) {
console.dir(JSON.parse(body.toString()));
})
.then(null, function (err) {
console.error('Failed to read JSON');
console.error(err.stack || err.message || err);
});Get a promise that is resolved when the stream has ended. This won't make any attempt to look at the data of the stream.
Buffers the contents of the stream using concat-stream and returns a promise for the concatenated results.
Buffers the contents of the stream into an array and returns a promise for the array.
