Provide example with parcel

[PSanetra]

An example using parcel is missing.

It should use the resolver and reporter plugins mentioned in here and ignore the spa_config.js file in the index.html:
parcel-bundler/parcel#2398 (comment)

.parcelrc:

{
  "extends": "@parcel/config-default",
  "resolvers": ["parcel-resolver-ignore", "..."],
  "reporters": ["...", "parcel-reporter-static-files-copy"]
  // ...
}

package.json:

{
  "parcelIgnore": [
    ".*/spa_config\\.js"
  ],
  "staticFiles": {
   // This is a little dirty as `spa_config.js` must be in `public` and in `public/scripts`
   // See https://github.com/elwin013/parcel-reporter-static-files-copy/issues/20
    "staticPath": "public/scripts"
  },
  "devDependencies": {
    "parcel": "^2.4.0",
    "parcel-reporter-static-files-copy": "^1.3.4",
    "parcel-resolver-ignore": "^2.0.0"
  }
}
