This is a small scraper I built for finding, downloading, and replacing external assets in open source projects. It might be useful if you're trying to deploy an open-source project on a local network (without Internet access).
I built this one specifically for use with FreeCodeCamp, but it should be useful for similar projects as well.
Just make sure you have Python and wget installed.
Copy this script into your project, and run:
./uncdn.py scrape
This will build the external assets list (by default links.txt). Check which ones you want to download, delete the ones you don't, and download them by running:
./uncdn.py download
Lastly, running:
./uncdn.py internalize
will switch the external urls for local ones.
Make sure to move the assets downloaded to the external folder to a publicly available location on your server. This, of course, depends on your server configuration.
Feel free to change in the code the regex used to "detect" external assets.
