BASH: express command not recognized-CodePudding

I've read other forums on installing express, I have run: npm install express -g on command prompt as admit

npm install express locally

I did this a few times and restarted my computer multiple times but still express isn't recognized

any help is appreciated

CodePudding user response：

Express isn't a web server; it is a framework for building web servers.

The express package doesn't provide anything directly executable.

The express documentation has a getting started guide.

If you aren't trying to do server-side programming using Node.js and just want an HTTP server, then the http-server package may be more your speed.

Assuming you’ve already installed Node.js, create a directory to hold your application and make that your working directory.

then follow the below command

npm init

follow step press enter and after

npm install express

make index.js file paste below hello work program.

const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => {
  res.send('Hello World!')
})

app.listen(port, () => {
  console.log(`Example app listening on port ${port}`)
})

Now you can run file using below command

node index.js

Open your broswer and enter URL : http://localhost:3000/

You can display Hello World!

You have successfully installed node js and express js program.
