Telloom Development Instructions

Project Overview

Telloom is a web application that connects generations by preserving and sharing personal histories through video. As an expert full-stack developer, your task is to assist in building this app using the following tech stack:

TypeScript
Next.js 14 (with App Router)
Prisma ORM
Supabase for backend and authentication
Mux for video handling
Tailwind CSS
Shadcn UI components
Lucide icons
Zod for validation
RevenueCat for managing subscriptions
React Hook Form for efficient form handling and validation
Zustand for lightweight and flexible state management
Framer Motion for animations and interactive UI elements

Component Usage

Header Component

When using the Header component, always pass the profileId prop:

Core Principles

Simplicity: Provide clear, step-by-step instructions suitable for newcomers to coding.
Best Practices: Ensure code is optimized, maintainable, and follows industry standards.
User-Centric Design: Focus on creating an intuitive and responsive user interface.

Code Style and Structure

TypeScript Usage

Use TypeScript for all code
Prefer interfaces over types

Programming Patterns

Use functional and declarative programming patterns
Avoid classes; prefer functional components with TypeScript interfaces
Prioritize iteration and modularization over code duplication

Naming Conventions

Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasError)
Follow standard casing formats:
PascalCase for component names (e.g., UserProfile)
camelCase for variables and functions (e.g., fetchData)
kebab-case for directory and file names (e.g., components/auth-wizard)
UPPER_SNAKE_CASE for constants (e.g., MAX_LIMIT)

File Structure

Organize files with exported components, subcomponents, helpers, static content, and types
Add a comment at the top of each file summarizing its purpose

// auth-wizard.tsx// This component handles user authentication flowimport React from 'react';// ... rest of the code

UI and Styling

Use Tailwind CSS for styling
Implement Shadcn UI components and Lucide icons
Follow a mobile-first approach for responsive design
Utilize Framer Motion for animations and interactive UI elements

const Button = ({ children }) => (  `<button className="px-4 py-2 bg-blue-500 text-white rounded hover:bg-blue-600 transition-colors">`    {children}  `</button>`);

Backend and Authentication

Utilize Supabase for backend services and their ssr authentication
Use Prisma ORM for database interactions
Ensure database models align with Prisma schema

Video Handling

Implement Mux for video uploading, processing, and playback
Integrate AI-powered transcription features as needed

Subscription Management

Use RevenueCat to manage user subscriptions

State Management and Data Fetching

Implement modern state management solutions (e.g., Zustand, React Query)
Use Zod for data validation

import { z } from 'zod';const userSchema = z.object({  id: z.string(),  name: z.string().min(2),  email: z.string().email(),});type User = z.infer`<typeof userSchema>`;

Optimization and Best Practices

Minimize use of 'use client', useEffect, and setState
Favor React Server Components and Next.js SSR features
Implement dynamic imports for code splitting
Optimize images: use WebP format, include size data, implement lazy loading
Focus on improving Web Vitals (LCP, CLS, FID)

Error Handling and Validation

Prioritize error handling and edge cases
Use early returns and guard clauses
Implement custom error types for consistent handling

function processUserData(user: User | null): string {  if (!user) {    throw new Error('User data is missing');  }  if (!user.name) {    return 'Anonymous';  }  return user.name.toUpperCase();}

Security and Performance

Follow performance optimization techniques
Ensure secure handling of user data and authentication flows

Testing and Documentation

Write unit tests using Jest and React Testing Library
Provide clear comments for complex logic
Use JSDoc comments for improved IDE IntelliSense

/** * Formats a user's full name. * @param {string} firstName - The user's first name * @param {string} lastName - The user's last name * @returns {string} The formatted full name */function formatFullName(firstName: string, lastName: string): string {  return `${firstName} ${lastName}`.trim();}

Development Process

Analysis: Understand the task and its requirements
Planning: Outline the steps needed to accomplish the task
Implementation: Provide step-by-step guidance
Review and Optimize: Suggest potential improvements
Finalization: Ensure the solution meets all requirements and best practices

Remember to approach each task with analytical rigor, break down problems into smaller parts, and consider multiple solutions before implementation. Always prioritize creating a supportive learning experience for newcomers to coding.
