Backend API Integration - Implementation Complete

Overview

This document details the complete backend API integration for the Indeedhub Prototype application. The integration connects the Vue 3 frontend with the NestJS backend (indeehub-api) and incorporates Nostr social features from the indeehub repository, while maintaining the existing glassmorphic UI design.

Usage Examples

Authenticating

// Cognito Login
import { useAuth } from '@/composables/useAuth'

const { login } = useAuth()
await login('user@example.com', 'password')

// Nostr Login
import { loginWithNostr } from '@/composables/useAuth'

const pubkey = await window.nostr.getPublicKey()
const signedEvent = await window.nostr.signEvent(authEvent)
await loginWithNostr(pubkey, signedEvent.sig, signedEvent)

Fetching Content

import { useContentStore } from '@/stores/content'

const contentStore = useContentStore()
await contentStore.fetchContent()

// Access content
const featuredContent = contentStore.featuredContent
const filmRows = contentStore.contentRows.featured

Using Nostr Social Features

import { useNostr } from '@/composables/useNostr'

const { comments, fetchComments, postComment, reactions, postReaction } = useNostr(contentId)

// Fetch comments
await fetchComments()

// Post comment
await postComment('Great film!')

// Post reaction
await postReaction(true) // +1
await postReaction(false) // -1

Checking Access

import { useAccess } from '@/composables/useAccess'

const { checkContentAccess, hasActiveSubscription } = useAccess()

const access = await checkContentAccess(contentId)
if (access.hasAccess) {
  // Allow playback
  console.log(`Access via: ${access.method}`) // 'subscription' or 'rental'
}

Development Mode

The app runs in development mode with mock data by default:

// src/stores/content.ts
const USE_MOCK_DATA = import.meta.env.VITE_USE_MOCK_DATA === 'true' || import.meta.env.DEV

Set VITE_USE_MOCK_DATA=false in .env to use real API in development.

Production Setup

1. Configure Environment Variables

   cp .env.example .env
   # Edit .env with production values
   

2. Set API URL

   VITE_API_URL=https://api.indeedhub.com
   VITE_CDN_URL=https://cdn.indeedhub.com
   

3. Build

   npm run build
   

4. Deploy

   docker-compose up -d
   

Routes

Route	Component	Auth Required	Description
/	Browse.vue	No	Main browsing page
/library	Library.vue	Yes	User's library
/profile	Profile.vue	Yes	User profile

Design Consistency

All new components follow the established glassmorphic design:

/* Glass Card Example */
.glass-card {
  background: rgba(255, 255, 255, 0.05);
  backdrop-filter: blur(24px);
  border-radius: 16px;
  border: 1px solid rgba(255, 255, 255, 0.08);
  box-shadow: 
    0 8px 24px rgba(0, 0, 0, 0.3),
    inset 0 1px 0 rgba(255, 255, 255, 0.1);
}
