# Development Dockerfile for Next.js AI Studio Application
# Issue #607 - Local Development Environment with Hot Reload
#
# This Dockerfile is optimized for development with:
# - Source code mounted as volume (not copied)
# - Dependencies pre-installed for fast startup
# - Hot module reloading enabled
#
# Usage:
#   docker compose -f docker-compose.dev.yml up
#
# Key differences from production Dockerfile:
# - Uses dev dependencies
# - No build step (source mounted at runtime)
# - Runs `bun run dev` instead of production server

FROM oven/bun:1.3-alpine

WORKDIR /app

# Install dependencies for native packages
RUN apk add --no-cache libc6-compat

# Copy package files and patches first (for layer caching)
COPY package.json bun.lock ./
COPY patches/ ./patches/

# Install ALL dependencies including devDependencies
RUN bun install --frozen-lockfile

# Don't copy source code - it's mounted as a volume
# The app will be run via docker-compose with volume mounts
