如何在客户端使用“要求”？

Question

I'm trying to set up a local server using node.js and the server works fine on the terminal but i got this error on the browser "Uncaught ReferenceError: require is not defined" any help will be appreciated thanks in advance

 // Setup empty JS object to act as endpoint for all routes projectData = {}; // Require Express to run server and routes const express=require('express'); //Require cors and body parser const cors=require('cors'); const bodyParser=require('body-parser'); // Start up an instance of app const app=express(); //Setting port to listen to const port=3200; //server testing server=app.listen(port,function(){ console.log(`server running on port ${port}`) }) /* Middleware*/ //Here we are configuring express to use body-parser as middle-ware. app.use(bodyParser.urlencoded({ extended: false })); app.use(bodyParser.json()); // Cors for cross origin allowance app.use(cors()); // Initialize the main project folder app.use(express.static('website')); // Setup Server //setting up a get route app.get('/getRoute',getCallback()) //get function function getCallback(req,res){ res.send(projectData); console.log(projectData); } //setting up a post route app.post('/postRoute',postCallback()) //get function function postCallback(request,response){ newData={ temperature:request.body.temperature, date:request.body.date, userResponse:request.body.userResponse } projectData.push(newData); }

that's the server side code for getting temperature information and showing it in the browser

Answer 1

This is because require() does not exist in the browser/client-side. Use <script>...</script> tag in browser.

Answer 2

Try using browserify, and also it is a nice quick extension to use if you are working on a small project that you want to get working on the client-side right away. check out this article it might help you.
