How to Secure Your Next.js E-commerce Site with RBAC and Permit.io
- When building an e-commerce application, or any application that has to factor in user roles or some role level access, proper authorization becomes a very important business detail.
- In this tutorial, we will be building an e-commerce site that allows a user to sign up, create a store, and add a store manager. We’ll learn how we can use Permit.io to implement role-based access control in our Next.js e-commerce app.
- Permit is a full stack authorization as a service platform that allows you to build and manage permissions for your application with a friendly SDK and API.
- RBAC is a method of regulating access to computer or network resources based on the roles of individual users within an organization. The main components of RBAC include: Roles, Permissions, Users and Resources.
- We need a way to sync the users in our app with the users on permit.io. To achieve this we need a unique way to identify our users. It doesn’t matter what method of authentication we are using, we just need a unique id for each user. For this project, we are using JWT, so we can decode our JWT and use the user ID or email to sync users to permit.
- Using Permit.io for role-based access control (RBAC) allows us to manage roles and permissions for the e-commerce application easily. We can create roles, add resources and manage the permissions for resources in the policy editor.
- We were able to enforce role-based access control by using permit API. With this API, we checked the permissions of the currently signed in user before rendering pages such as create store, inventory and add manager.
- In the add manager page, we checked if the current user had “Admin” rights and only enabled the form for adding managers if the user had permission.
- We have successfully used Permit.io in our Next.js app to enforce permissions and add co-ownership feature for store owners.
- The complete tech stack for this tutorial includes: Vercel Postgres our managed Postgres database, Drizzle for our ORM, and Next.js our full stack framework.
