JSDoc

[shmygol]

It would be nice if JSDoc were preserved to enable autocompletion for custom functions.

Generally agreed!
I'm waiting for your PullRequest!

I don't have much experience with esbuild, but it doesn't seem to be possible: evanw/esbuild#294.

@shmygol
Sorry, I understand what you are requesting.
You want this plugin to also output JSDoc for functions implemented by the user.
Is this correct?

[shmygol]

Correct. It is essential, because custom formulas in Google Spreadsheets need JSDoc to support auto-completion and user documentation. Instead of using esbuild-gas-plugin I ended up bundling the business logic with an esbulid parameter glabalName: 'Main' and push the bundle together with an unmodified custom index.js containing formulas and hooks required by GAS like this:

/**
 * Hello World
 *
 * @param {string} name Your name
 * @return {string}
 * 
 * @customfunction
 */
function HELLO(name) {
    return Main.hello(name);
}
