# Stage 1: Build the Angular application
FROM node:18 as build

WORKDIR /app

# Install dependencies first (better caching)
COPY package*.json ./
RUN npm install

# Copy source code
COPY . .

# Build for production with specific base-href
RUN npm run build -- --configuration production --base-href /ocrf/

# Stage 2: Serve via Nginx
FROM nginx:alpine

# Remove default nginx static assets
RUN rm -rf /usr/share/nginx/html/*

# Create target directory (since we use /ocrf/ base-href)
RUN mkdir -p /usr/share/nginx/html/ocrf

# Copy built assets from builder stage
# Note: Adjust 'dist/frontend/browser' based on your angular.json output path. 
# Angular 17+ creates 'browser' folder.

# Copy custom nginx config
COPY nginx.conf /etc/nginx/conf.d/default.conf
