feat: esm format

[privatenumber]

Currently, when importing native ESM packages ("type": "module"), I get the following error:

internal/modules/cjs/loader.js:1080
      throw new ERR_REQUIRE_ESM(filename, parentPath, packageJsonPath);
      ^

Error [ERR_REQUIRE_ESM]: Must use import to load ES Module: /Users/pvtnbr/Documents/public-github/privatenumber/vue-search/node_modules/fs.promises.exists/index.js
require() of ES modules is not supported.
require() of /Users/pvtnbr/Documents/public-github/privatenumber/vue-search/node_modules/fs.promises.exists/index.js from /Users/pvtnbr/Documents/public-github/privatenumber/vue-search/src/index.ts is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.
Instead rename index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/pvtnbr/Documents/public-github/privatenumber/vue-search/node_modules/fs.promises.exists/package.json.

I believe this is happening because esbuild is converting the esm import to cjs requires.

Seems like there's an overrides option to pass in format: 'esm' here, but I'm guessing this is only available for the Node.js API.

Can esbuild-register pass in format: 'esm' to esbuild if a flag is set or if the current project package.json has type: 'module' set?

Any idea about this one?

Converting "require" to "esm" is currently not supported

I got a few errors like this (can provide repro if needed). I seem to hit https://github.com/evanw/esbuild/issues/566
