Basic design for Job Portal Management System

This is a backend application for a Job Portal Management System it uses Node.js, Express.js, MongoDB. In this project I have tried to follow REST APIs architecture. The APIs have various features such as pagination.

Features

• User authentication (login/signup)
• Create job (admin/recruiter)
• Apply for job
• View applied jobs
• Delete application
• Search/filter jobs (by title, location, etc.)

Database Collections

1. Users

• _id (ObjectId)
• firstName (string)
• lastName (string)
• email (string, unique)
• password (string, hashed)
• role (string: "admin", "recruiter", "applicant")
• createdAt (Date)

2. Jobs

• _id (ObjectId)
• title (string)
• company (string)
• location (string)
• description (string)
• createdBy (ObjectId, references Users._id)

3. Applications

• _id (ObjectId)
• userId (ObjectId, references Users._id)
• jobId (ObjectId, references Jobs._id)
• status (string: "applied", "rejected", "accepted")
• appliedAt (Date)

APIs

• POST - /auth/signup : Sign up the user
• POST - /auth/login : Login the user
• GET - /user/me : Get the profile of user
• POST - /jobs : Create new job
• GET - /jobs : Get all jobs

• GET - /jobs/:id/applicants : Recruiter gets all the user applied for his job
• DEL - /jobs/:id/applications : User can delete his application for a job
• PATCH - /jobs/:id/applicants : Recruiter can manage the application i.e. accept or reject the application
