ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
The 'request' npm package is a simple, yet powerful HTTP client that supports multiple features such as making HTTP calls, handling responses, streaming data, and more. It is designed to be the simplest way possible to make http calls and supports HTTPS and follows redirects by default.
Simple HTTP GET requests
This code performs a simple HTTP GET request to Google's homepage and logs the error, response status code, and the response body.
const request = require('request');
request('http://www.google.com', function (error, response, body) {
console.log('error:', error);
console.log('statusCode:', response && response.statusCode);
console.log('body:', body);
});
Streaming data
This code demonstrates how to stream data from an HTTP request directly to a file, which can be useful for downloading files or handling large amounts of data.
const request = require('request');
const fs = require('fs');
const stream = fs.createWriteStream('file.txt');
request('http://www.google.com').pipe(stream);
Custom HTTP headers
This code shows how to send a custom HTTP header (in this case, the User-Agent header) with a request. This is often required when using certain APIs, like GitHub's.
const request = require('request');
const options = {
url: 'https://api.github.com/repos/request/request',
headers: {
'User-Agent': 'request'
}
};
function callback(error, response, body) {
if (!error && response.statusCode == 200) {
const info = JSON.parse(body);
console.log(info);
}
}
request(options, callback);
Handling POST requests
This code snippet demonstrates how to send a POST request with form data, including how to upload a file as part of that form data.
const request = require('request');
const options = {
method: 'POST',
url: 'http://service.com/upload',
headers: {
'Content-Type': 'multipart/form-data'
},
formData: {
key: 'value',
file: fs.createReadStream('file.txt')
}
};
request(options, function (error, response, body) {
if (error) throw new Error(error);
console.log(body);
});
Axios is a promise-based HTTP client for the browser and Node.js. It provides a simple API for making HTTP requests and is often used as an alternative to 'request' due to its promise support and interceptors for request/response manipulation.
Got is a human-friendly and powerful HTTP request library. It is designed to be a simpler and more performant alternative to 'request', with features like streams support, promise API, and better error handling.
Node-fetch is a light-weight module that brings the Fetch API to Node.js. It is an alternative to 'request' that provides a simpler, promise-based API for making HTTP requests, similar to what is available in modern web browsers.
Superagent is a small progressive client-side HTTP request library, and Node.js module with the same API, sporting many high-level HTTP client features. It compares to 'request' by offering a fluent API and being lightweight.
npm install request
Request is designed to be the simplest way possible to make http calls. It support HTTPS and follows redirects by default.
The first argument is an options object. The only required option is uri, all others are optional.
'uri'
- fully qualified uri or a parsed url object from url.parse()'method'
- http method, defaults to GET'headers'
- http headers, defaults to {}'body'
- entity body for POST and PUT requests'client'
- existing http client object (when undefined a new one will be created and assigned to this property so you can keep around a reference to it if you would like use keep-alive on later request)followRedirect
- follow HTTP 3xx responses as redirects. defaults to true.requestBodyStream
- Stream to read request body chunks from.responseBodyStream
- Stream to write body chunks to. When set this option will be passed as the last argument to the callback instead of the entire body.The callback argument gets 3 arguments. The first is an error when applicable (usually from the http.Client option not the http.ClientRequest object). The second in an http.ClientResponse object. The third is the response body buffer.
Example:
var request = require('request'); request({uri:'http://www.google.com'}, function (error, response, body) { if (!error && response.statusCode == 200) { sys.puts(body) // Print the google web page. } })
It's also worth noting that the options argument will mutate. When following a redirect the uri values will change. After setting up a client options it will set the client property.
