[question] Can esbuild generate types.d.ts ?

[mesqueeb]

I could not find info on this in the documentation nor in the current existing issues.

Does ESBuild support generating a single types.d.ts file when I bundle (with format esm) a index.ts file?

I'm currently using rollup which does it, but I wanna evaluate if I can switch out to esbuild?

an example of a types.d.ts generated by rollup look like the snippet below.

Please note it retains the correct type information as well as the JSDocs.

/**
 * Returns whether the payload is undefined
 *
 * @param {*} payload
 * @returns {payload is undefined}
 */
export declare function isUndefined(payload: any): payload is undefined;
/**
 * Returns whether the payload is null
 *
 * @param {*} payload
 * @returns {payload is null}
 */
export declare function isNull(payload: any): payload is null;

I believe that a types.d.ts file is useful for when other devs use my utils to get autocompletion and popup documentation in their editors.

If this is not possible with esbuild, am I correct to assume that my use case:

• bundling JS utils which I host on NPM in esm format with autocompletion and popup documentation

is not the target use case for esbuild? I'm keen to know!

previously I searched for generate types which didn't get good results in the issues, but now I did find the answer here:
