TypeScript and NodeJS: The Proper Setup!

Why dir called "server" and no "src"? (naming best practice)

do you have a link to your github or is it private

Your explanation is very clear

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" ?

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({
title: "Un authorized",
message: err.message,
stack: err.stack,
})
break;

case 403: res.json({
title: "Forbidden",
message: err.message,
stack: err.stack,
})
break;

case 404: res.json({
title: "Not found",
message: err.message,
stack: err.stack,
})
break;

case 500: res.json({
title: "Server Error",
message: err.message,
stack: err.stack,
})
break;

default:
console.log('No error, all good.');
break;
}
}

export default errorHandler;

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.

how does tsc still work after you moved it into a folder? That doesnt make sense.

Enjoyed watching your video!

tsx (package, not react's tsx), is better than ts-node
it just always works
even lets you execute .ts files directly with this hashbang `#!/usr/bin/env tsx`

gooodddd, thank youuuu

Great! Thank you!

You actually forgot to install typescript as a full complete explanation. Thanks for the video
