1-27: Add SSL configuration and performance optimizationsThe configuration needs SSL support and performance optimizations for production use.
Add the following configurations:

90-90: LGTM! Improved Docker build efficiency.The modified prepare script now skips husky installation in production environments. This change:
- Reduces Docker image size by preventing git hooks installation
- Aligns with the PR's goal of optimizing Docker resource usage
- Maintains development workflow while improving production builds
Consider documenting this optimization in the Dockerfile or deployment docs to help other contributors understand the importance of this change.

1-3: LGTM! Good choice of base image
Using node:20.10.0-alpine as the builder base image is optimal for reducing image size while maintaining reproducibility.
10-13: LGTM! Proper build configuration
Setting NODE_ENV=production before build is correct for optimizing the build process.
4-9: 🛠️ Refactor suggestion
Optimize dependency installation and file copying
Several optimizations can improve build efficiency and reduce image size:
WORKDIR /talawa-admin
COPY package*.json ./
-RUN npm install
+RUN npm ci --production=false
-COPY . .
+COPY package-lock.json ./
+COPY public ./public

8-10: Add performance optimizations for static contentThe root location block should include caching and compression configurations for better performance.
Consider adding these optimizations:
location / { + # Enable compression + gzip on; + gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript; + + # Cache static assets + location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg)$ { + expires 30d; + add_header Cache-Control "public, no-transform"; + } + try_files $uri /index.html; }
32-32: Enhance error handling and loggingThe current error handling is minimal. Consider adding comprehensive error pages and logging configuration.
Add these configurations:
+ # Error pages error_page 404 /index.html; + error_page 500 502 503 504 /50x.html; + + # Logging + access_log /var/log/nginx/talawa_admin_access.log combined buffer=512k flush=1m; + error_log /var/log/nginx/talawa_admin_error.log warn;

}1-34: Verify Docker integration and environment setup
Let's ensure the Nginx configuration aligns with the Docker setup and environment variables.
✅ Verification successful
Let me gather more information about the environment setup and Docker configuration.
Docker integration and Nginx configuration are properly set up
The verification shows that:
- Nginx configuration is correctly integrated with Docker setup
- The Dockerfile properly copies the nginx.conf to the correct location
- Static files are correctly mounted from the build output
- Environment variables are properly handled through the build process
No issues found with the current setup. The configuration follows standard practices for a React application served through Nginx in a Docker container.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify Docker integration and environment setup
# Check Docker-related files for nginx configuration
echo "Checking Dockerfile for nginx setup..."

5-14: Enable SSL and configure HTTPSThe SSL configuration is currently commented out. As per the PR objectives, enabling HTTPS is crucial for secure communication. Consider uncommenting and properly configuring the SSL settings.
If you need assistance setting up SSL certificates and configuring HTTPS, I can help generate the necessary configuration steps.
23-23: Enable and configure theContent-Security-PolicyheaderTo enhance security against cross-site scripting and other attacks, consider enabling the
Content-Security-Policyheader.Apply this diff to enable the header:
- # add_header Content-Security-Policy "default-src 'self'; connect-src 'self' https://your-graphql-server.com;"; + add_header Content-Security-Policy "default-src 'self'; connect-src 'self' https://your-graphql-server.com;";

Parameterize the server_name directive via an environment variable
Currently, the server_name is hard-coded to domain.com. To make the configuration adaptable across different environments, consider parameterizing it.
Apply this diff to parameterize the server_name:

Parameterize the proxy_pass URL
The proxy_pass directive is hard-coded to http://127.0.0.1:4000/graphql/. To allow flexibility for different back-end services or environments, consider parameterizing this value.

Parameterize the Access-Control-Allow-Origin header
The Access-Control-Allow-Origin header is set to a specific domain. To accommodate different front-end domains or environments, consider parameterizing this value.
Apply this diff to parameterize the header:
- add_header Access-Control-Allow-Origin https://your-react-app-domain.com;
+ add_header Access-Control-Allow-Origin ${ALLOWED_ORIGINS};

1-3: Good choice of base image and stage naming!
Using the Alpine-based Node.js image and proper stage naming helps minimize the image size.
