Add TypeScript type definitions

[Aaromal2]

Currently quick-socket is JavaScript only.

It would be great to add TypeScript type definitions (.d.ts file) so TypeScript developers can use the package with full type safety.

What needs to be done:

• Create src/index.d.ts
• Add types for all exported functions
• Add types for MESSAGE_TYPES and STATUS

Good first issue for TypeScript developers!

Hi! I’d like to work on this issue. I’m new to open source, but I’ll try adding the TypeScript definitions in src/index.d.ts.

Implemented TypeScript support by adding src/index.d.ts with type definitions for all exported functions and constants. Also updated package.json with the types field and added a short README note so TypeScript users get definitions out of the box.
