Currently, I am working on developing a website specifically for my school. One of the key features I want to include is the ability for students to easily download files (specifically, PDFs) using node.js. The concept is quite simple - students will be presented with multiple links and by clicking on any link, the downloading process will commence automatically.
If you have tagged this as express, it's a safe bet that express is already installed via npm. Assuming the files are located in the downloads directory within that folder, you can utilize the res.download module provided by Express. Take a look at this straightforward example:
const express = require("express");
const path = require("path");
const app = express();
app.get("/downloads/:file", (req, res) => {
res.download(
path.join(__dirname, "downloads/" + req.params.file),
(err) => {
if (err) res.status(404).send("<h1>Not found: 404</h1>");
}
);
});
app.get("/", (req, res) => {
// Code to display download links here
});
app.listen(3000);
Simply access
http://localhost:3000/downloads/file.pdf./downloads/file.pdf
