Parcel & Robots

There are different ways to tell ParcelJS which files are static and should not go through the build transformation, but if there are only a few, you can activate the transformers plugin and then include them directly in the build script in the package.json file.

// package.json
{
  "scripts": {
    "build": "parcel build src/index.html src/robots.txt src/favicon.ico"
  }
}

This way, robots.txt and favicon.ico will not be processed by ParcelJS and will be directly transferred to the build directory.

Transformers plugin

To make the above build script work properly, you need to add the following code to the .parcelrc file:

// .parcelrc
{
  "extends": "@parcel/config-default",
  "transformers": {
    "*.{txt,ico}": ["@parcel/transformer-raw"]
  }
}

So ParcelJS will not add hashes to the names of the files, but also the linked objects in the files being processed will not be changed.
