How to use nodejs to build an online job search platform

With the popularity of the Internet, online recruitment has become one of the main channels for job seekers and recruiting companies. With the development of technology, more and more job search platforms have appeared on the market. In the process, Node.js has become a very popular open source platform that is fast, cross-platform, and easy to write and modify. In this article, we will create an online job search platform using Node.js.

First, we need a database to store job seeker and company information. In this regard, we can use MongoDB, which is a widely used NoSQL database. We can use Mongoose, a Node.js library, to help us connect to the MongoDB database and create corresponding models.

We need to create two basic models: job seeker and company. Since there is a relationship between them, we can use nesting to achieve the relationship. For example, we can add an array named jobs to the company model to store position information for the company. In the job seeker model, we can add an array of jobApplications to store the job information applied for by the job seeker.

Next, we need to create a routing module to handle user requests. We can use the Express.js framework to quickly create routes. We can use the following route:

• GET /jobs: Returns all job information.
• GET /jobs/:id: Returns specific job information.
• POST /jobs: Create a new job information.
• PUT /jobs/:id: Update specific job information.
• DELETE /jobs/:id: Delete specific job information.

We also need to create an identity authentication system so that users can register, log in and log out. We can use Passport.js to help us handle authentication.

Finally, we need to create a front-end page to display job information and allow users to search. We can use the Pug template engine to simplify page development. We can use the following page:

• /: Displays a list of all job information.
• /jobs/:id: Displays detailed information for a specific position.
• /login: Display the login form.
• /register: Display the registration form.
• /profile: Display user information.

In the development of this online job search platform, we used Node.js, Express.js, Mongoose, Passport.js and Pug to create a complete platform. Our platform has a variety of functions, including identity authentication, job listings, job search and job application functions. This is a good example of how to use Node.js to create modern web applications.
