Expose incremental Compile-on-Save builder API · Issue #17493 · microsoft/TypeScript
In #10879, @sheetalkamat is working on bringing the same logic in the language server to Compile-on-Save. We would like to expose that as an API so that other build tools (e.g. Webpack loaders, gulp plugins, Broccoli plugins) and editors (any editor using TS Server) can get: automated resolution logic to detect which files need to be "updated" incremental type-checks to only check the bare minimum
Created a branded type for identifier-escaped strings by weswigham · Pull Request #16915 · microsoft/TypeScript
Then flowed it throughout the compiler, finding and fixing a handful of bugs relating to underscore-prefixed identifiers in the process. Includes a test for two (new) cases noticed - diagnostics from conflicting symbols from export *'s, and enums with underscore prefixed member emit. I mentioned this while talking among the team last week. This can be done in place of/alongside #16868. Additionall
TypeScripts Type System is Turing Complete · Issue #14833 · microsoft/TypeScript
This is not really a bug report and I certainly don't want TypeScripts type system being restricted due to this issue. However, I noticed that the type system in its current form (version 2.2) is turing complete. Turing completeness is being achieved by combining mapped types, recursive type definitions, accessing member types through index types and the fact that one can create types of arbitrary
Boolean literal types and return type propagation for generators · Issue #2983 · microsoft/TypeScript
This suggestion has a few pieces: Implement boolean literal types for true and false, in a fashion similar to Singleton types under the form of string literal types #1003 Implement type guards for booleans. Essentially, control flow constructs like if-else, while, for, etc would be subject to a type guard if their guard expression is a boolean. Now we can update generators to have a next method th
Suggestion: Add the nameof compile-time operator to convert property and function names into strings · Issue #1579 · microsoft/TypeScript
I would like to see the nameof operator be considered for Typescript. This feature was just added to C# description, and it is an elegant solution to a common issue in Javascript. At compile time, nameof converts its parameter (if valid), into a string. It makes it much easier to reason about "magic strings" that need to match variable or property names across refactors, prevent spelling mistakes,
