In this article, we’ll explore how to set up a Role-Based Access Control (RBAC) system where features are a central part. We'll go through defining modules, associating features, assigning roles with specific features, and finally assigning roles to users. This example uses JSON data to keep things simple and adaptable, allowing for scalable access control without requiring any changes for new roles on the frontend
1. Define Modules and Features
Modules group similar features together. Each module can contain multiple features representing actions that users can perform.
JSON Structure for Modules and Features:
{
"modules": [
{
"id": 1,
"name": "Users",
"features": [
"view-users",
"edit-users"
]
},
{
"id": 2,
"name": "Reports",
"features": [
"view-reports",
"edit-reports"
]
}
]
}
- Modules: Represents a specific area of the application, like "Users" or "Reports."
-
Features: Actions within each module, such as
view-usersandedit-usersfor theUsersmodule.
2. Create Roles and Assign Features
Next, create roles that define sets of features. Each role will have a list of permissions that grant access to specific features within the modules.
JSON Structure for Roles and Permissions:
{
"roles": [
{
"id": 1,
"name": "Admin",
"permissions": [
"view-users",
"edit-users",
"view-reports",
"edit-reports"
]
},
{
"id": 2,
"name": "Viewer",
"permissions": [
"view-users",
"view-reports"
]
}
]
}
- Roles: Represent groups with specific access rights, like "Admin" and "Viewer."
- Permissions: Specify which features each role has access to, allowing for flexible permission settings.
By defining roles, you can manage access control efficiently without modifying each user's permissions.
3. Assign Roles to Users
After creating roles, assign them to users. Each user will inherit the permissions granted by their role.
JSON Structure for Users and Role Assignments:
{
"users": [
{
"id": 1,
"name": "Sushant",
"roleId": 1
},
{
"id": 2,
"name": "Raghav",
"roleId": 2
}
]
}
- Users: Represent individuals who will access the application.
- RoleId: Links each user to a specific role, determining their feature access.
With this structure, you can easily update roles to grant or restrict access for multiple users simultaneously.
4. Setting Up Access Control Logic in the Frontend
On the frontend, access to each feature is checked based on the user's role. Here’s how to securely handle user access based on their assigned role.
- Fetch Role Permissions: When a user logs in, retrieve their role's permissions from the backend.
- Store Permissions Locally: For session-based access control, store permissions in a secure format (such as JWT or session storage).
- Conditional Rendering: For each section or feature, check if the user has permission to view or edit it.
Example Access Check in JavaScript:
const userPermissions = ["view-users", "edit-users"]; // Loaded from backend based on role
if (userPermissions.includes("view-users")) {
// Render the user view section
}
if (userPermissions.includes("edit-users")) {
// Render the user edit section
}
Using a role-based check in the frontend ensures that users only see features they’re permitted to access.
Conclusion
Role-Based Access Control (RBAC) 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, you can easily create and manage custom roles without requiring any new changes in the frontend.
