Create a full-stack application using Next.js for the front end and NestJS for the backend to build, manage, and persist a tree structure with a depth of 10,000 nodes.
- Frontend: Set up a new Next.js project. 🌐
- Backend: Set up a new NestJS project. 🔧
- Version Control: Initialize a Git repository for version control. 🗃️
- Follow best practices for code structure and modularization in the Next.js project.
- Create basic components (e.g., TreeNode, Tree).
- Implement a simple username input form.
- Set up state management (e.g., React context or Redux) for managing user state.
- Set up the basic structure for the NestJS project.
- Integrate a database (e.g., MongoDB, PostgreSQL). 🗄️
- Design and implement a schema for storing user information and tree structures. 📝
- Create an endpoint to validate and register unique usernames. 🔐
- Implement robust input validation and error handling for these endpoints.
- Create React components to represent tree nodes. 🖼️
- Design a UI that can handle a tree with significant depth, considering performance and usability. ⚙️
- Implement functionality to handle clicks on leaf nodes.
- Ensure that when a leaf node is clicked, we can edit its value, and its value is updated and propagated up to all its parent nodes.
