Question 1

How do I validate RemoteEvent data with t in Roblox?

Accepted Answer

Use t.wrap to encapsulate your RemoteEvent handler functions with type definitions like t.tuple or t.interface. This ensures incoming data matches expected types, preventing server errors from invalid inputs, as highlighted in the README's security focus.

Question 2

t or roblox-ts for type checking in Roblox?

Accepted Answer

t is a runtime library for Lua, providing validation during execution, while roblox-ts is a TypeScript compiler with static types. Choose t if you need runtime safety in pure Lua; opt for roblox-ts for compile-time checks and modern tooling.

Question 3

How to make optional fields in a table with t?

Accepted Answer

Use t.optional within t.interface definitions. For example, `t.interface({Name = t.string, Score = t.optional(t.number)})` allows the Score field to be nil or a number, as shown in the interface examples.

Question 4

Does t integrate with Luau's type annotations?

Accepted Answer

t is compatible with Luau but doesn't leverage its static type features. You can use t for runtime validation independently, though it doesn't provide cross-tool synergy for development-time checks.

Question 5

What's the performance cost of using t in a Roblox game?

Accepted Answer

Runtime checks add overhead, particularly for complex validations or high-frequency calls. Profile your game to assess impact, and consider limiting checks to critical paths like Remote events to balance safety and performance.

Question 6

How to create a custom type checker for my Roblox classes with t?

Accepted Answer

Implement a function that returns a boolean and error message, then integrate it with t's composition functions. The README's Tips and Tricks section shows an example for OOP frameworks, but it requires manual setup for error handling.
