A guide to `tsconfig.json`

I never felt confident about my tsconfig.json. To change that, I went through the official documentation, collected all common options, and documented them in this blog post: This knowledge will enable you to write a tsconfig.json that is cleaner and that you’ll fully understand. If you don’t have the time to read the post, you can jump to the summary at the end where I show the tsconfig.json that I use now – along with recommendations for adapting it to different use cases (npm package, app, etc.). I also link to the tsconfig.json recommendations by several well-known TypeScript programmers. (I went through them when I researched this post.).
