Crate ts_typegen 

Marker derive for types that should have TypeScript bindings generated.

Generation itself happens in a build script via the ts-typegen-build crate. This derive expands to nothing; it exists so that #[ts(...)] is legal syntax and so the build-time scanner has a marker to look for.

Pair it with #[derive(Serialize)], since bindings describe the JSON serde actually writes:

use serde::Serialize;
use ts_typegen::Ts;

#[derive(Serialize, Ts)]
#[serde(rename_all = "camelCase")]
struct User {
    user_id: u64,
    name: String,
    #[serde(skip)]
    secret: String,
}

#[ts(...)] is the escape hatch for anything serde’s shape doesn’t capture on its own — see the crate README for the full attribute list.

Traits

TsType

Marks a type as having a known TypeScript binding. Implemented for every type the lowering pipeline understands; a field whose type has no impl fails to compile instead of silently emitting unknown.

Derive Macros

Ts

The Ts derive macro. See the crate-level docs for what it does.
