I used to love Sublime Text and used it for my daily driver. Even bought a license.
But just downloaded it again, and while it definitely felt snappy, after 15 minutes I still couldn't find a way to get TypeScript type checking working, or even any type of JavaScript/TypeScript autocomplete.
If you want IDE-like behavior you'll need to install the TypeScript LSP: https://packagecontrol.io/packages/LSP-typescript. We do have our own limited language-agnostic indexing and auto-complete if you open your projects folder; it relies on existing code to provide suggestions.
Oh, that's frustrating. I think it'd be great to have some more concrete guides for modern Sublime. Maybe I'll write one about getting TypeScript and everything working starting from scratch
