Shareable Twoslash Comments

A TypeScript Playground plugin that injects twoslash (// ^?) type hints as literal comments in your code, making them easy to copy and share.

This plugin also supports twoslash arrow queries (//=>).

If placed at the end of a line, it finds the first position on that line with type information and inserts it.

let foo = 1; //=> number

If placed on its own line, it looks at the previous line, finds the first position with type information, and inserts it.

let foo = 1;
//=> number
