This code snippet will create a JSON response to some API route. This line assigns the string value "Success" to the jsonString object under the 'Result' key. It's a way to store key-value pairs in a JavaScript Object [LINK] . This snippet doesn't send anything more, than just what the jsonString object holds, which is either "Result" with the "Success" message or "Error" with a description. It will be converted to JSON and will be sent as a response: res.send(JSON.stringify(jsonString)) . Generally 'app' is an instance of some HTTP server [LINK] in Node.js It's just a structuring/naming practice, this can be highly different from project-to-project. To get started with Node.js apps, check o

You need to know at least a little Javascript, and at least a little about how to write a NodeJS app with Javascript. If you don't, get a book and/or work through some tutorials. For example (Google NodeJS tutorial): [LINK] [this video] Next, download MS App Studio and work through a tutorial. For example: [LINK]

I'm following a [this video] on NodeJs, and for some reason my console.log commands unexpectedly stopped working. Here is the sample code from the tutorial as I've typed it: const http = require('http'); const server = http.createServer(); server.on('connection', (socket) => { console.log('New connection') }); server.listen(3000); console.log('Listening on port 3000...'); After saving I try using node and nodejs node app.js nodejs app.js but they print nothing.
Cites RNdev · 2020-12 · Stack Overflow · on “Why does the asynchronous nature of Node.js make it bad for video/image manipulation?”
In this video [this video] at 9:42 it mentions that while Node is useful for IO-intensive apps because it does fetches/requests asynchronously, it "should not be used for CPU-intensive application like video encoding or image manipulation" because in these apps "there are a lot of calculations done by the CPU". Can anyone give me a better picture of how IP threads and the CPU are used in IO-intensive vs CPU-intensive apps? Specifically: In an IO-intensive app, say you make a server request, Node has 1 thread that puts that request in the event queue. What thing takes the request from the event queue and handles it? In a CPU-intensive app, why can't individual calculations by put in the event queu
