ts-toolbelt@9

[millsp]

Hey folks!

I'm proud to announce that our latest release 9 is one of a special kind. As the type system and TypeScript have matured aggressively this last year 2020, so did ts-toolbelt.

The TypeScript team has delivered a lot this year. Recursive types, template literals, variadic tuples, you name it! This has brought many changes in ts-toolbelt, which emulated many TypeScript features. The biggest game changer was probably the template literals, which not only helped to sanitize the code base, but also improved type safety and the overall ts-toolbelt API. Performance is also up, with less type instantiations, and less memory usage. Build times are consistent, but don't increase as we add features.

What does this mean for you?

• Benefit from a reorganized, simpler API
• Breaking changes, as we improve with TS
• A new String category has been opened
• Safer types, overall, edge cases caught
• New questions will be posted in discussions

But don't worry, most types are still where they were last.

What's going to be done this year?

• Do a (more) complete performance review
• Build the documentation site with Svelte
• Continue bringing extraordinary types 🥳
  • Soon to come: Exact, Narrow, and AutoPath
