Node.js - Deliver HTML or any other sort of file
Start
  Deliver HTML at specified path

Here's how to create an Express server and serve index.html by default (empty path /), and page1.html for /page1 path.

Folder structure

project root
|    server.js
|____views
     |    index.html
     |    page1.html

server.js

var express = require('express');
var path = require('path');
var app = express();

// deliver index.html if no file is requested
app.get("/", function (request, response) {
  response.sendFile(path.join(__dirname, 'views/index.html'));
});

// deliver page1.html if page1 is requested
app.get('/page1', function(request, response) {
    response.sendFile(path.join(__dirname, 'views', 'page1.html', function(error) {
        if (error) {
            // do something in case of error
            console.log(err);
            response.end(JSON.stringify({error:"page not found"}));
        }
    });
});

app.listen(8080);

Note that sendFile() just streams a static file as response, offering no opportunity to modify it. If you are serving an HTML file and want to include dynamic data with it, then you will need to use a template engine such as Pug, Mustache, or EJS.

Syntax

  • response.sendFile(fileName, options, function (err) {});
