[esbuild-plugin-html] Add a preprocess step for HTML plugin ?

[iamvdo]

Hello,

I tested many (if not all) esbuild html plugins, and this is by far the better. But I have one question: how about adding a preprocess option, that lets user execute task on html at the start of the process? It could be useful to replace some text, or use a preprocessor.

For instance, something like this in the build, to preprocess using ejs

esbuild.build({
  ...,
  plugins: [htmlPlugin({
    preprocess(html) {
      return ejs.render(html, { title: 'A title' });
    }
  })]
})

And in the lib, just before lines 182/183 of lib/index.js:

let code = args.code;
if (preprocess) {
  code = preprocess(code);
}
const $ = loadHtml(code);

Maybe, I'm thinking in the wrong direction, but I cannot manage to use other preprocessor plugins (like ejs or pug) with HTML files. They all build JS.
Thanks.
