This is a skeleton app for people who want to use TypeScript. A docker-compose file is included for those who want to run it in a container.

You don't have to use the docker-compose file if you're fine with installing NodeJS and NPM locally. Feel free to delete it if that's the case.

1. Clone this repository to your pc
2. Make sure you have NodeJS installed (preferably the LTS version). This will also install npm.
3. Open a terminal window (command prompt, git bash, powershell)
4. Check if NodeJS is installed by typing node --version into the terminal. It should print a line with something like v16.13.0.
5. Check if NPM is installed by typing npm --version into the terminal. It should print a line with something like 8.1.0.
6. Open a terminal in the project directory.
7. Install the dependencies by running npm install.
8. Compile the project by running npm run build. If you want to run the build script everytime you make changes automatically, you can use npm run watch.
9. Open the tsconfig.json file in this project.
10. Search the TypeScript documentation and try to explain every line in the json file. Don't understand something? That's fine! Just don't copy stuff for the sake of filling up your answers.
11. Install the EditorConfig plugin in your code editor by either using its marketplace or manually installing it.
12. Install the ESLint Plugin in your code editor by either using its marketplace or manually installing it.
13. Find the error generated by ESLint in the src/app.ts file and fix it.

If you're like me and you dislike NodeJS and NPM piling up heaps of folders on your pc, run TypeScript in Docker!

1. Install Docker Desktop.
2. Open a terminal window (Powershell on Windows, regular command prompt will not work).
3. Clone this repository.
4. Move to this folder inside the terminal.
5. Run docker-compose up and open a new terminal OR run docker-compose up -d which allows you to work in the same terminal.
6. Follow the steps from Instructions from step 4, but prefix all the commands with docker-compose exec ts-app.
7. Close the docker container by pressing ctrl + c or docker-compose down, respectively for step 5
