Process for developing School Management System using Next js, Nest js & GraphQl API!
Published: 2024-06-13 15:02:18

Developing a comprehensive School Management System using Next.js, NestJS, and GraphQL involves several steps and considerations. Here's a high-level overview of how you can approach this project:

### Technology Stack:
- **Frontend:** Next.js (React framework)
- **Backend:** NestJS (Node.js framework)
- **API:** GraphQL
- **Database:** PostgreSQL (or any other relational database)
- **Authentication:** JWT (JSON Web Tokens) or OAuth
- **Styling:** TailwindCSS (optional)
- **State Management:** Redux or Context API (optional)

### Steps to Develop the System:

#### 1. **Project Setup:**
   - Initialize a Next.js project.
   - Initialize a NestJS project.
   - Set up a PostgreSQL database.

#### 2. **Frontend Development (Next.js):**
   - Create a folder structure for pages and components.
   - Implement authentication (login, registration) using NextAuth or a custom solution with JWT.
   - Develop reusable UI components (e.g., buttons, forms, modals).
   - Set up routing for different roles (admin, teacher, student, parent).

#### 3. **Backend Development (NestJS):**
   - Set up NestJS modules, controllers, and services.
   - Implement GraphQL with Apollo Server.
   - Set up database models using TypeORM or Prisma.
   - Implement authentication and authorization middleware.

#### 4. **GraphQL API:**
   - Define GraphQL schema for different entities (User, Student, Teacher, Class, Subject, etc.).
   - Implement resolvers for each entity.
   - Set up query and mutation operations.

#### 5. **Database Schema:**
   - Design database schema to include tables for users, students, teachers, classes, subjects, attendance, grades, events, etc.
   - Implement relationships between tables (e.g., one-to-many, many-to-many).

#### 6. **Feature Development:**
   - **User Management:**
     - Implement user registration, login, and profile management.
     - Role-based access control for different user roles.
   - **Academic Management:**
     - Develop features for class and subject management.
     - Implement timetable creation and management.
     - Attendance tracking and reporting.
   - **Communication Tools:**
     - Develop messaging system and email notifications.
     - Implement announcements and notices.
   - **Financial Management:**
     - Implement fee management system with billing and payments.
     - Generate financial reports.
   - **Learning Management System (LMS):**
     - Develop online course management, assignment submission, and virtual classroom features.
   - **Reports and Analytics:**
     - Generate various reports for academic performance, attendance, and finances.
   
#### 7. **Testing:**
   - Write unit and integration tests for backend using Jest.
   - Write component and end-to-end tests for frontend using Jest and Cypress.

#### 8. **Deployment:**
   - Set up CI/CD pipeline for automated testing and deployment.
   - Deploy the Next.js frontend and NestJS backend to a cloud provider like Vercel, AWS, or Heroku.
   - Set up database hosting and configuration.

### Example Code Snippets:

#### Next.js (Frontend) - Example of a Page Component:
```jsx
import { useState } from 'react';
import { useQuery, gql } from '@apollo/client';
import Layout from '../components/Layout';

const GET_CLASSES = gql`
  query GetClasses {
    classes {
      id
      name
      teacher {
        name
      }
    }
  }
`;

export default function Classes() {
  const { loading, error, data } = useQuery(GET_CLASSES);

  if (loading) return <p>Loading...</p>;
  if (error) return <p>Error: {error.message}</p>;

  return (
    <Layout>
      <h1>Classes</h1>
      <ul>
        {data.classes.map((cls) => (
          <li key={cls.id}>
            {cls.name} - {cls.teacher.name}
          </li>
        ))}
      </ul>
    </Layout>
  );
}
```

#### NestJS (Backend) - Example of a GraphQL Resolver:
```typescript
import { Resolver, Query, Mutation, Args } from '@nestjs/graphql';
import { ClassService } from './class.service';
import { Class } from './class.entity';
import { CreateClassInput } from './dto/create-class.input';

@Resolver(() => Class)
export class ClassResolver {
  constructor(private classService: ClassService) {}

  @Query(() => [Class])
  async classes() {
    return this.classService.findAll();
  }

  @Mutation(() => Class)
  async createClass(@Args('createClassInput') createClassInput: CreateClassInput) {
    return this.classService.create(createClassInput);
  }
}
```

#### GraphQL Schema Definition:
```graphql
type Class {
  id: ID!
  name: String!
  teacher: Teacher!
}

type Teacher {
  id: ID!
  name: String!
}

type Query {
  classes: [Class!]!
}

input CreateClassInput {
  name: String!
  teacherId: ID!
}

type Mutation {
  createClass(createClassInput: CreateClassInput!): Class!
}
```
