Script that generates a cache.ts file for any service

create_service_cache.sh

#!/bin/bash

# Service name for the TypeScript file.
service_name="$1"
file_name="cache.ts"

# Code content to write to the file.
code="import { revalidateTag } from \"next/cache\";

interface RevalidateProps {
  id?: string;
}

export const ${service_name}Cache = {
  tag: {
    byId(id: string) {
      return \`${service_name}-\${id}\`;
    },
  },
  revalidate({ id }: RevalidateProps): void {
    if (id) {
      revalidateTag(this.tag.byId(id));
    }
  },
};"

# Create the file in the current directory.
file_path="./packages/lib/$service_name/$file_name"

# Check if the file already exists.
if [ -e "$file_path" ]; then
  echo "Error: File '$file_path' already exists."
  exit 1
fi

# Create the file with the specified code.
echo "$code" > "$file_path"

echo "Created $file_path with the specified code."

Here is how to call the service.

/path/to/script nameOfService

Note that nameOfService must already exist in the packages/lib folder for it to add a cache.ts file
