ts-node-dev | Compiles your TS app and restarts when files | Build Tool library

For this project, I have a monorepo with 2 workspaces (api and frontEnd). I have upgraded node from V10 to V16 recently and the migration is almost complete. I can run it locally, but building is not possible anymore.

When I run yarn workspace api start:dev, defined in api/package.json as "start:dev": "cross-env NODE_ENV=development npx ts-node-dev -r dotenv/config -r tsconfig-paths/register --respawn --transpile-only src/index.ts", it runs smoothly on localhost.

When I run yarn workspace api build:ts, defined in api/package.json as yarn run tsc, I get errors of the following type (I kept only 1 error per file to respect the question character limit, but there are over 2000 lines):

I am trying to create an authentication middleware for my express server and I get no Type errors in my IDE but when I try to complile I am getting TypeError: Cannot read properties of undefined (reading protect). The route works fine without the middleware and the middleware has no detectable linting issues. I am also using socket.io so I tried io.use(wrap(middleware)) on the off chance it would work and it didn't but that was a shot in the dark anyway, the problem seems unrelated. I've also tried replacing ALL relevant type declarations with any and got the same problem.

I have been following several SO links on how to run both tsc -w and nodemon app.js in a single command.

Link which i followed: How do I execute typescript watch and running server at the same time?

I was working on a project in node.js with typescript. Each time when there is change in ts code, I want to compile using tsc -w and then execute running server with nodemon app.js file. The problem is I tried with both commands, but still it is not running the second command. I have no idea why it is not working.

Commands I used inside package.json scripts

"dev1": "tsc -w && nodemon ./.build/src/app.js",

"dev2": "tsc && concurrently \"tsc -w\" \"nodemon ./.build/src/app.js\""

Ran npm run dev1

Ran npm run dev2

Currently only the first command is running and I am not able to see the logs which will come when nodemon runs. Terminal is showing only below log:

Found 0 errors. Watching for file changes

[Note: both commands are running perfectly when i tried to run one after another]

Versions using (bit older)

typescript: 3.0.1

nodemon: 2.0.7

ts-node: 5.0.1

Any help would be really appreciated. I dont want to use any extra package like ts-node-dev.

I have a piece of code that's causing Node to log UnhandledPromiseRejectionWarning. But I'm not sure why. Here's the code boiled down:

In attempting to deploy an Express TypeScript server to Heroku, I am encountering an error. I ran heroku logs --tail and this is the output:

Well, I have pushed my TypeScript project to github, and it has these scripts:

So, I have been trying to create a docker for my "project", and it was working with a simple dockerfile without stages and docker-compose. But, now I'm trying to use stages and I think my changes shouldn't affect the project like this.

When I build the docker with docker-compose -f ./docker-compose.dev.yml up --build -d, all the 3 services start, but the web one which containes the node stuff tries to execute my yarn migration:run command, which worked only in the first try, and after that all I get is:

I'm currently building a system in Node with a Postgres db, and I've created a container using docker-compose for both. By running docker-compose up I manage to initialize all container (Node app, Postgres db and PGAdmin) and a connection is successfully established.
