Problems with Genrics on Lambda-functions

[misantronic]

There is a problem when compiling files with generics on lambda-functions.
Example:

const fn = <T>(Dependency: Constructable<T>, hint?: string): T =>
        ensureInjector().get(Dependency, hint);

It transpiles to this:

const fn = React.createElement(
      T,
      null,
      "(Dependency: Constructable",
      React.createElement(
        T,
        null,
        ", hint?: string): T => ensureInjector().get(Dependency, hint); // function fn",
        React.createElement(
          T,
          null,
          "(Dependency: Constructable",
          React.createElement(
            T,
            null,
            ", hint?: string): T ",
            fn.reset = () => {
              injector = void 0;
            },
            "; return fn; })();"
          )
        )
      )
    );

When changing the function to this it works:

function fn<T>(Dependency: Constructable<T>, hint?: string): T {
    return ensureInjector().get(Dependency, hint);
}

This just calls esbuild, so the issue is within that lib.

However, if I were to guess, I would suggest that maybe the tsconfig for the node app is configured with JSX.
That's a pretty weird issue though.
It has been a while, but I am pretty sure this plugin generates an esbuild.json file as well. You might turn off react options in there as well.
