Firebase Firestore/Storage security rules minifier. Current stable version 0.3.1 (latest, last updated 2020). Infrequently updated. Minifies Firebase security rules to stay under the 256KB (or effectively 50KB) size limit by removing comments, whitespace, unused functions, and renaming functions/parameters to shorter names. Different from hand-optimization as it automates the process without restructuring the database or moving validation to the client.
