API reference/Transformer

    Transformer

    The transformer rewrites supported syntax into JavaScript, including TypeScript constructs and class static blocks. Unlike type stripping, it can generate runtime code for TypeScript features such as parameter properties.

    Example

    Input
    class Point {
  constructor(public x: number) {}
}
    Output
    class Point {
  x;
  constructor(x) {
    this.x = x;
  }
}
