A bash script for downloading CDN assets for a Glitch project

README.md

Scrape Glitch Assets

Problem

When using glitch.com's Download Project tool (Tools > Import and Export > Download Project), the resulting archive does not include project assets that were uploaded to the Glitch CDN.

Solution

The download does however include a metadata file .glitch-assets that lists the project's CDN files.

This script downloads the files listed in a .glitch-assets file and writes them to a local directory.

Usage

# default looks for ./glitch-assets and writes downloaded files to current directory 
. scrape-glitch-assets.sh

# specify input file and output directory
. scrape-glitch-assets.sh /path/to/.glitch-assets -o /path/to/output/directory

scrape-glitch-assets.sh

#!/bin/bash
#
# Scrape assets listed in a .glitch-assets file and save them to a local directory.

glitch_assets_path='.glitch-assets'
output_dir='.'

while [[ $# -gt 0 ]]; do
  case "$1" in
    -o)
      output_dir="$2"
      shift
      shift
      ;;
    *)
      glitch_assets_path="$1"
      shift
      ;;
  esac
done

while IFS= read -r line; do
	url=$(echo "$line" | jq -r 'select(.url != null).url') 

	if [ "$url" ]
	then
		name=$(echo "$line" | jq -r '.name') 
		curl "$url" -o "$output_dir/$name"
	fi
done < "$glitch_assets_path"
