Troubleshooting

How to kill server when seeing EADDRINUSE: address already in use

  1. To find the process id (PID) associated with the port
lsof -i tcp:1668

It'll display as below. Please note down the PID from that

COMMAND PID   USER  FD  TYPE DEVICE                SIZE/OFF NODE NAME
node   44475 chen5 31u IPv4 0x8b1721168764e4bf 0t0 TCP *:strexec-s (LISTEN)
  1. Then to kill the process by PID
kill -9 44475

-source

Extra help

Creating tsconfig.json file

  • if typescript is added globally tsc --init
  • if not added globally npx tsc --init

If you wish to run angular and backend simultaneously,

Add the following to the package.json file of angular

"scripts": {
    ...
    "server": concurrently \"ng serve\" \"ts-server/node_modules/.bin/ts-node-dev server/server.ts\"
}

By using concurrently, whenever we run npm serve we'll get both the backend and front-end spun up and live reloading whenever we make any changes to the application.

Test that CORS is working

Please try to run the following cURL command simulation in your terminal:

curl -H "Origin: http://localhost:3000" --head http://localhost:5201/api/v1/your-name

If you check the response, you'll notice that there is now an Access-Control-Allow-Origin header with the origin http://localhost:3000. This means that when you run your client-side app on http://localhost:3000 , the app will be able to retrieve resources from your server.

How to Add All Files to a Git Commit Except Some?

You can use any command to add all files you wish to stage (like git add . for example), followed by git reset to unstage the ones you want to exclude:

git add .

# excluding file:
git reset -- path/to/file.txt

# excluding folder:
git reset -- path/to/folder/*

For this repo, Please add the following command after staging all the files to exclude the file db-data-extra.ts

git reset -- src/db/db-data-extra.ts

Cloning Guide

clone only the remote primary HEAD (default: origin/master)

git clone <url> --single-branch

Only specific branch

git clone <url> --branch <branch> --single-branch [<folder>]
git clone <url> --branch <branch>

Cloning repositories using degit

npx degit github:user/repo#branch-name <folder-name>
  • master branch is default.
