expressjsHow can I use Express.js to answer questions?
Express.js is a web application framework for Node.js that can be used to answer questions. It provides a simple way to create web applications and APIs.
To use Express.js to answer questions, you can use the app.get()
method to create routes that will respond to HTTP requests. For example, the following code creates a route that will respond to a GET request with a simple
const express = require('express')
const app = express()
app.get('/answer', (req, res) => {
res.send('The answer is 42')
})
app.listen(3000, () => {
console.log('Listening on port 3000')
})
This code will create an Express.js server that responds to the /answer
route with the response The answer is 42
.
The main parts of the code are:
const express = require('express')
: This imports the Express.js module.const app = express()
: This creates an Express.js application.app.get('/answer', (req, res) => {
: This creates a route that responds to a GET request.res.send('The answer is 42')
: This sends the responseThe answer is 42
to the client.app.listen(3000, () => {
: This starts the Express.js server on port 3000.
For more information, see the Express.js documentation.
