• we need to manually install the peer dependencies for building the project

if we want to use this package with a link / file reference we need to install the packages we need to install the modules from peerdependencies (WITHOUT ADDING THEM TO PACKAGE.JSON) build the project remove the node modules again and optionally install the modules from package.json again (without the peerdependencies in the node modules)

solution: https://github.com/wclr/yalc

Development using yalc:

• npm install -g yalc
• build this project yarn build
• yalc publish
• in the project where you'd like to use this package, run yalc add <package name>
  • this will make it so a file reference will be added to the local package in your project folder
  • yalc link somehow does not work for class-transformer, so we'll have to add a precommit hook to check if we're not accidentally commiting yalc references. yalc check
  • add to .gitignore:
    • .yalc
    • yalc.lock
• After changes made: yarn build && yalc push

Stop:

• In destination: yalc remove --all
• In package repo: yalc installations clean {packageName}
