Role-Based Access Control (RBAC) with Feature-Centric Approach

This article discusses setting up a Role-Based Access Control (RBAC) system where features are central. The system involves defining modules, associating features, assigning roles with specific features, and assigning roles to users. The example uses JSON data for simplicity and adaptability, allowing for scalable access control without requiring changes for new roles on the frontend. Modules group similar features together, representing actions that users can perform. Each module can contain multiple features, such as view-users and edit-users for the Users module. Roles define sets of features, with each role having a list of permissions that grant access to specific features within the modules. Roles represent groups with specific access rights, like Admin and Viewer, while permissions specify which features each role has access to. By defining roles, access control can be managed efficiently without modifying each user's permissions. Users are assigned roles, inheriting the permissions granted by their role. The JSON structure for modules, features, roles, and users allows for easy updates to grant or restrict access for multiple users simultaneously. On the frontend, access to each feature is checked based on the user's role, with permissions stored locally in a secure format. Conditional rendering is used to check if the user has permission to view or edit a feature. Using a role-based check in the frontend ensures that users only see features they're permitted to access. The RBAC system with a feature-centric approach offers a scalable and efficient way to manage user permissions. By defining modules and features, setting up roles, and assigning or updating features to roles, custom roles can be easily created and managed without requiring changes in the frontend.
