I wanted to be able to easily create markdown checklists of entire Magic: The Gathering sets using the Scryfall API, so I threw this ultra-simple script together.
$ node index.js SET
After installing the dependencies with your package manager of choice, simply run the command node index.js SET, replacing SET with the set's abbreviation (e.g. 'LRW' for Lorwyn). It should work with the set name for sets with single-word names (e.g., again, Lorwyn) or single words that Scryfall links directly to a particular set (e.g. 'Betrayers' for Betrayers of Kamigawa), but I really only wrote this with the abbreviations in mind, so searches for multiple words aren't currently supported. It also only looks up unique cards in each set - although I'm likely to change this soon because it annoys the completionist in me.
The results of the search are written to a markdown file in the ./output directory using your query as the file name and heading. Each individual card is listed as - [ ] # Card Name. So, for example, a search for Lorwyn would output:
# LORWYN
- [ ] 1 Ajani Goldmane
- [ ] 2 Arbiter of Knollridge
...
- [ ] 298 ForestI may or may not make additions or improvements depending on my future needs and/or laziness. However, I'm happy to accept PRs with changes.
