Config externals shortcut

[flamrdevs]

Is there a config shortcut to auto externals dependencies / peerDependencies?

Something like this

{
  "esbuild": {
    "external": "auto",
  }
}

Unfortunately there currently isn't, but I'll look into adding it

Hey @okikio , first of all thanks for the amazing work.

It would great if we can automatically add peerDependencies in the npm package.json into esbuild.external config.

For example, an React UI npm package usually has "react" and "react-dom" as peer dependencies, in the default config we should have:

{
  "esbuild": {
    "external": ["react", "react-dom"]
  }
}

@szhsin I'm hesitant to enable that by default for react, as people still check the raw bundle size of react, but what I will do instead is support an auto option that automatically marks peerDeps as external.

Sorry @flamrdevs I forgot to enable this feature last year, I'll be enabling later this week.
