To serve a single static file with Express.js, we can use the express.static middleware.
For instance, we can write:
const express = require('express')
const app = express()
const port = 3000
app.use("/foo.txt", express.static(__dirname + '/foo.txt'));
app.get('/', (req, res) => {
res.send('hello world')
});
app.listen(port, () => {
console.log(`Example app listening at http://localhost:${port}`)
})
to add:
app.use("/foo.txt", express.static(__dirname + '/foo.txt'));
to use the express.static middleware to expose the foo.txt file to the public.
We make it accessible by making a request to “/foo.txt” since that’s the first argument we passed into app.use .
And we make it serve the foo.txt file from the current working directory with:
express.static(__dirname + '/foo.txt')
So when we make a request to /foo.txt , we would see its contents in the response.
