Simplified HTTP/HTTPS requests
A nicer interface to the built-in http module.
It supports following redirects, streams, automagically handling gzip/deflate and some convenience options.
Created because request is bloated (several megabytes!) and slow.
Install
$ npm install --save got
Usage
var got = require('got');
// Callback mode
got('todomvc.com', function (err, data, res) {
console.log(data);
//=> <!doctype html> ...
});
// Promise mode
got('todomvc.com')
.then(function (res) {
console.log(res.body);
})
.catch(console.error);
// Stream mode
got.stream('todomvc.com').pipe(fs.createWriteStream('index.html'));
// For POST, PUT and PATCH methods got.stream returns a WritableStream
fs.createReadStream('index.html').pipe(got.stream('todomvc.com', {method: 'POST'}));
API
It's a GET request by default, but can be changed in options.
got(url, [options], [callback])
url
Required
Type: string, object
The URL to request or bare http.request options object.
Properties from options will override properties in the parsed url.
options
Type: object
Any of the http.request options.
body
Type: string, Buffer, ReadableStream
This option and stream mode are mutually exclusive.
Body that will be sent with a POST request. If present in options and options.method is not set - options.method will be set to POST.
If content-length or transfer-encoding is not set in options.headers and body is a string or buffer, content-length will be set to the body length.
encoding
Type: string, null
Default: 'utf8'
Encoding to be used on setEncoding of the response data. If null, the body is returned as a Buffer.
json
Type: boolean
Default: false
This option and stream mode are mutually exclusive.
Parse response body with JSON.parse and set accept header to application/json.
query
Type: string, object
Query string object that will be added to the request URL. This will override the query string in url.
timeout
Type: number
Milliseconds after which the request will be aborted and an error event with ETIMEDOUT code will be emitted.
callback(error, data, response)
Function to be called, when error or data recieved. If omitted - Promise will be returned.
error
Error object with HTTP status code as code property.
data
The data you requested.
response
The response object.
When in stream mode, you can listen for events:
.on('request', request)
request event to get the request object of the request.
.on('response', response)
response event to get the response object of the final request.
.on('redirect', response, nextOptions)
redirect event to get the response object of a redirect. Second argument is options for the next request to the redirect location.
.on('error', error, body, response)
error event emitted in case of protocol error (like ENOTFOUND etc.) or status error (4xx or 5xx). Second argument is body of server response in case of status error. Third argument is response object.
got.get(url, [options], [callback])
got.post(url, [options], [callback])
got.put(url, [options], [callback])
got.patch(url, [options], [callback])
got.head(url, [options], [callback])
got.delete(url, [options], [callback])
Sets options.method to the method name and makes a request.
Proxy
You can use the tunnel module with the agent option to work with proxies:
var got = require('got');
var tunnel = require('tunnel');
got('todomvc.com', {
agent: tunnel.httpOverHttp({
proxy: {
host: 'localhost'
}
})
}, function () {});
Tip
It's a good idea to set the 'user-agent' header so the provider can more easily see how their resource is used. By default it's the URL to this repo.
var got = require('got');
got('todomvc.com', {
headers: {
'user-agent': 'https://github.com/your-username/repo-name'
}
}, function () {});
Node 0.10.x
It is a known issue with old good Node 0.10.x http.Agent and agent.maxSockets, which is set to 5. This can cause low performance of application and (in rare cases) deadlocks. To avoid this you can set it manually:
require('http').globalAgent.maxSockets = Infinity;
require('https').globalAgent.maxSockets = Infinity;
This should only ever be done if you have Node version 0.10.x and at the top-level application layer.
