Pull esbuild configuration from package.json entry

[dpilafian]

New Feature

For extra convenience (and to reduce the clutter of yet another project configuration file), add support for storing the esbuild configuration directly in the project's package.json file.

Something like:

package.json

  ...
  "esbuildConfig": {
    "entry": "./index.js",
    "outfile": "./bundle.js",
    "external": ["react", "react-dom"],
    "loader": { ".js": "jsx", ".png": "base64" },
    "minify": true
  },
  "scripts": {
    "build": "esbuild $(esbuild-config package.json:esbuildConfig)"
  },
  ...

Good idea!

We could even drop the package.json:esbuildConfig and check the package.json if no esbuild.config.json is present and no file path has been passed.

For the key, I think it would be safe to use "esbuild" directly, since esbuild doesn’t plan to support config files.

Yeah, that's even better -- simple and works automatically.
