Previously Existing Dependencies (Verified)

The following dependencies were already present and verified:

✅ @mediapipe/selfie_segmentation@^0.1.1675465747 - Person segmentation
✅ mediasoup-client@^3.18.5 - WebRTC client for mediasoup
✅ simple-peer@^9.11.1 - WebRTC wrapper
✅ webrtc-adapter@^9.0.3 - Browser compatibility layer
✅ hls.js@^1.6.15 - HLS (HTTP Live Streaming) player

Installation Results

Installation Command

pnpm install

Status

✅ All dependencies installed successfully

Warnings

Minor peer dependency warnings (non-critical):
- tree-sitter version mismatch (0.22.4 vs 0.21.1)
- canvas version mismatch (2.11.2 vs 3.0.0) - using older version for compatibility
Some Nhost packages deprecated (security patches continue until March 31)

Build/Compilation Notes

canvas: Successfully compiled native module with some warnings (expected)
mediasoup: Downloaded prebuilt binary for darwin-arm64
@signalapp/libsignal-client: Prebuilt binary available

Import Verification

All dependencies can be imported correctly:

// Cryptography
import { secp256k1 } from '@noble/curves/secp256k1'
import { sha256 } from '@noble/hashes/sha256'

// WebRTC
import * as mediasoupClient from 'mediasoup-client'
import adapter from 'webrtc-adapter'

// Video streaming
import Hls from 'hls.js'

// Simple peer
import * as SimplePeer from 'simple-peer'

Special Handling Required

Server-Side Only

mediasoup: Can only be imported in Node.js environment (API routes, server components)
canvas: Requires Cairo system dependencies, Node.js only

Native Modules

@signalapp/libsignal-client: Requires proper Node.js environment
canvas: Requires Cairo, Pango, and related libraries

Browser vs Server

Use dynamic imports with typeof window !== 'undefined' checks for client-only libraries
Use Next.js API routes for server-only dependencies
