Compressing and Decompressing User Permissions with JavaScript

User permissions are an essential part of any applicationโ€™s security model. One major use case for compressing and decompressing user permissions is to include the compressed permissions in an authentication token.

When a user login and obtained the access token, you can attach their permissions to the token.

Decompressed:
