Add promise support to superagent using Bluebird
npm install superagent-bluebird-promise
superagent-bluebird-promise
===========================
Add promise support to
Superagent using
Bluebird.
npm install superagent-bluebird-promisesuperagent. Then you can call .then() or .catch() instead of .end() to get a promise for your requests.``javascript
var request = require('superagent-bluebird-promise');
// .then()
request.get('/an-endpoint')
.then(function(res) {
console.log(res);
}, function(error) {
console.log(error);
});
// .catch()
request.get('/an-endpoint')
.catch(function(error) {
console.log(error);
});
`
To generate a promise without registering any callbacks (e.g. when returning a promise from within a library), call .promise() instead.
`javascript`
request.get('/an-endpoint').promise()
In order to use any of Bluebird's various promise methods, make sure you call .then() or .promise() first.
An error is thrown for all HTTP errors and responses that have a response code of 400 or above.
The error parameter always has a key error and for 4xx and 5xx responses, will also have a status and res key.
You can abort the request by cancelling the promise:
`js``
promise.cancel();
This is only possible because we have configured bluebird to be cancellable by default.
