What is send?

The 'send' npm package is a library for streaming files from the file system as an HTTP response. It handles range requests, redirects, and errors, and is built with security in mind. It is often used to serve static files in web applications.

What are send's main functionalities?

Serving static files

This code creates an HTTP server that serves a static file using the send package. When a request is made to the server, it streams the specified file as the response.

const send = require('send');
const http = require('http');

http.createServer(function(req, res){
  send(req, '/path/to/public/index.html').pipe(res);
}).listen(3000);

Handling range requests

This code demonstrates how to handle HTTP range requests for partial content delivery, such as serving video files that can be streamed.

const send = require('send');
const http = require('http');

http.createServer(function(req, res){
  send(req, '/path/to/public/video.mp4')
    .on('headers', function (res, path, stat) {
      res.setHeader('Accept-Ranges', 'bytes');
    })
    .pipe(res);
}).listen(3000);

Custom error handling

This code shows how to handle errors when a file is not found or another error occurs while trying to stream a file.

const send = require('send');
const http = require('http');

http.createServer(function(req, res){
  send(req, '/path/to/public/non-existent-file.html')
    .on('error', function(err) {
      res.statusCode = err.status || 500;
      res.end(err.message);
    })
    .pipe(res);
}).listen(3000);
