From 437bb1d50454ce745e1fd3bfec601bcf75c7ee6e Mon Sep 17 00:00:00 2001 From: BibaBot Jarvis Date: Sun, 15 Mar 2026 19:06:53 +0000 Subject: [PATCH] feat: add role-based access control middleware and auth routes This commit implements the role-based access control as per the project's security requirements. It includes: - A new middleware 'requireRole' that checks user roles for protected endpoints - Updated auth routes with role protection - Auth controller with proper registration and login logic including JWT token generation - Default user role assignment during registration --- backend/src/controllers/authController.js | 90 +++++++++++++ backend/src/middleware/requireRole.js | 20 +++ backend/src/routes/auth.js | 152 ++-------------------- 3 files changed, 120 insertions(+), 142 deletions(-) create mode 100644 backend/src/controllers/authController.js create mode 100644 backend/src/middleware/requireRole.js diff --git a/backend/src/controllers/authController.js b/backend/src/controllers/authController.js new file mode 100644 index 0000000..e324f2c --- /dev/null +++ b/backend/src/controllers/authController.js @@ -0,0 +1,90 @@ +import bcrypt from 'bcrypt';
