Process for developing School Management System using Next js, Nest js & GraphQl API!

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:

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:

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);
  }
}
Enter fullscreen mode Exit fullscreen mode

GraphQL Schema Definition:

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!
}
Enter fullscreen mode Exit fullscreen mode

This outline provides a structured approach to building a School Management System using Next.js, NestJS, and GraphQL. You can expand on each section to include more detailed implementations and additional features as needed.
