Hi greggsworld. You should be able to do that with something like this: "dev": "tsc-watch --onSuccess \"yarn start\"", "start": "node dist/app.js" using tsc-watch will keep an eye out for code changes
maybe for some others here a simple or stupid question, but is nodejs used in big companies for their backend? or is this just some sort of "hobby backend library" ?
Probably the biggest in the industry. What else compares in adoption? Low level systems use a lot of C but companies want many good devs and good libs. So community size is a proxy for that. Js has biggest community, node is server js.
@@0xSLN javascript is so big because it is basically required on the front-end. On the back-end, there are tons of options that are faster and more mature than node.js. I doubt it's the most popular.
you're mixing require and esm syntax. You should look into what adding "type": "module" does or what using the .cjs and .mjs file extensions do. I'm sure you've already solved the problem but I'm just leaving this here for future reference.
Such a quick and clear tutorial. Wonderful job!
Your explanation is very clear
Great video, I am having a problem, I can’t use ts-node with esm, I keep getting an error
Why dir called "server" and no "src"? (naming best practice)
I was going to ask this. Still, great video.
where can I find that wallpaper
how tsc command is automatically executing server/index.ts ?
You actually forgot to install typescript as a full complete explanation. Thanks for the video
thanks man, step by step explan.. really help
This was great! Thank you so much. It would be great if you added server restart on code changes to avoid having to start and stop - like nodemon.

thanku brother for this valuable information
Enjoyed watching your video!
how does tsc still work after you moved it into a folder? That doesnt make sense.
Many help, thank you

yeah LinkedIn and nasa are just hobby backend thing

@@redeemr Its based on number of projects on github. But popular doesn't equal best, lots of langs that are better at specific things.
Express has around 22M+ weekly downloads as of today
Amazing!
god tier level video
Great! Thank you!
thanks , so helpful
Great🚀🚀❤❤
do you have a link to your github or is it private
belot han ongs na sokor yaa

don't use ts-node use vite-node and save your time!
it's not good tutorial you why you don't show how to use modules etc. ?
I don't know why I'm getting this error :/
\middleware\errorHandler.ts:45
export default errorHandler;
^^^^^^
SyntaxError: Unexpected token 'export'
My server.ts file:
const express = require("express");
const errorHandler = require("./../middleware/errorHandler");
const dotenv = require("dotenv").config();
const app = express();
const port = process.env.PORT || 5000;
app.use(express.json());
app.use("/api/contacts", require("./../routes/contactRoutes"));
app.use(errorHandler);
app.listen(port, () => {
console.log(`Server running on port ${port}`);
})
and
errorHandler.ts file:
import {Request, Response} from 'express';
type typeErrorHandler = {
err: {message: string, stack: string[]},
req: Request,
res: Response,
next: string,
}
const errorHandler = ({err,req,res,next} : typeErrorHandler) =>{
const statusCode = res.statusCode ? res.statusCode : 500;
switch (statusCode) {
case 400: res.json({
title: "Validation Failed",
message: err.message,
stack: err.stack,
})
break;
case 401: res.json({
