Next.js Development Practical Tools and Resources Recommendation: From Deployment to Performance Optimization\n\nNext.js, as a full-stack framework for React, has become a popular choice for modern web development. Its server-side rendering (SSR), static site generation (SSG), API routing, and other features greatly improve development efficiency and user experience. However, to fully leverage the potential of Next.js, it is necessary to use some practical tools and resources. This article will recommend some very helpful tools, technologies, and best practices in the Next.js development process based on recent discussions on X/Twitter.\n\n## 1. Deployment Optimization: Embrace CDN, Say Goodbye to Server Priority\n\nAs @@ilanchezhian27 said, the trend of modern front-end deployment is CDN-first, not server-first. For most static sites (React/HTML, Next.js without SSR), hosting on a CDN has significant advantages:\n\n* Global Caching: Accelerates loading speed and reduces latency.\n* Automatic Traffic Handling: No need to worry about high concurrency issues, CDN can automatically scale.\n* Static Resource Optimization: Very suitable for static resources such as images, videos, JavaScript, and CSS.\n\nOperation Guide:\n\n1. Choose the right CDN provider: Common CDN providers include Cloudflare, AWS CloudFront, Azure CDN, Tencent Cloud CDN, etc. Choose the right CDN according to your needs (e.g., coverage, price, features).\n2. Configure CDN: Deploy your Next.js project to a static resource storage service supported by CDN (e.g., AWS S3, Tencent Cloud COS). Then, configure the origin address in the CDN console to be your storage bucket address.\n3. Enable Caching: Configure the CDN's caching strategy, such as setting the cache expiration time (TTL). Usually, for resources that are not updated frequently, you can set a longer cache time.\n4. Optimize Static Resources: Use tools (e.g., Webpack, Parcel) to compress and optimize your static resources to reduce file size.\n5. Test CDN: Use online tools (e.g., WebPageTest, GTmetrix) to test your website's loading speed in different regions to ensure that the CDN is working properly.\n\nPractical Tools:\n\n* Webpack Bundle Analyzer: Analyzes the package size of your Next.js project and identifies areas for optimization.\n* Image Optimization Tools (TinyPNG, ImageOptim): Compress images, reduce file size, and improve loading speed.\n* CDN Speed Test Tools: Test CDN loading speed in different regions.\n\n## 2. User First: Focus on Core Functionality, Not Technology Stack\n\n@@BuiltByArya's experience tells us that users really care about whether the problem can be solved quickly, not what technology stack you used. When developing the Eatly application, they used a combination of Next.js + AI + OCR to achieve the following functions:\n\n1. Upload/scan menu (OCR extracts dishes).\n2. AI analyzes each dish.\n3. Get instant recommendations.\n\nBest Practices:\n\n* MVP (Minimum Viable Product) First: Focus on core functionality, iterate quickly, and continuously improve based on user feedback.\n* Choose the Right Technology Stack: Choose the right technology stack based on project requirements and team skills, and don't blindly pursue new technologies.\n* Focus on User Experience: Optimize website performance, usability, and accessibility to provide a good user experience.\n\n## 3. Fast Iteration: Build High-Performance Web Applications\n\n@@punyakrit_22 emphasized the importance of execution. The technology stack they used includes:\n\n* Next.js + React + Node.js\n* Postgres + Supabase + AI integrations\n* Clean architecture + Scale readyKey Steps:

1. Design a Clear Architecture: Use a clean architecture (e.g., layered architecture, domain-driven design) to improve code maintainability and scalability.
2. Optimize Database Queries: Use techniques such as indexes and caching to optimize database query performance.
3. Leverage Supabase or Firebase: Quickly build backend services, such as user authentication and data storage.
4. Integrate AI Services: Utilize AI services like OpenAI and Google AI to add intelligent features to your application.

4. Open Source Templates: Accelerate Store Setup

@@zaiste shared an open-source Next.js template library to accelerate store setup. This can help developers launch a store in minutes instead of weeks. Shopify themes used to be popular, but open-source Next.js templates offer greater flexibility and customization.

How to Use:

1. Choose the Right Template: Browse the template library and choose a template that suits your needs.
2. Clone the Template: Clone the template to your local machine.
3. Install Dependencies: Run npm install or yarn install to install dependencies.
4. Configure the Template: Modify the template configuration according to your needs, such as store name, logo, product information, etc.
5. Deploy the Application: Deploy the application to platforms like Vercel and Netlify.

Recommended Resources:

• Next.js Commerce: The official Next.js e-commerce template provided by Vercel.
• Awesome Next.js: A GitHub repository that collects a large number of Next.js resources (including templates, components, and libraries).

5. Code Reuse: React Native Expo + Next.js

@@codewithrohit shared a method for building cross-platform applications using React Native Expo and Next.js. This method allows you to use the same TypeScript code on both mobile and web, achieving code reuse.

Key Steps:

1. Create a React Native Expo Project: Use the expo init command to create a React Native Expo project.
2. Create a Next.js Project: Use the create-next-app command to create a Next.js project.
3. Share Code: Place the shared code (e.g., components, type definitions, business logic) in a shared directory.
4. Configure TypeScript: Configure TypeScript so that both projects can access the code in the shared directory.
5. Build Applications: Build the React Native Expo application and the Next.js application separately.

Useful Tools:

• TypeScript: Ensure type safety and improve code maintainability.
• React Native Expo: Quickly build cross-platform mobile applications.

6. Performance Optimization: Lighthouse 100 Points

@@myogeshchavan97 successfully increased the Lighthouse score of his Next.js portfolio website to 100%. Lighthouse is a tool in Google Chrome Developer Tools that can help you analyze website performance, accessibility, best practices, and SEO.

**Optimization Tips:**1. Optimize Images: Use compression tools to optimize images, and use the next/image component to implement image lazy loading and responsive loading. 2. Code Splitting: Use dynamic imports (import('...')) to implement code splitting and reduce the initial loading JavaScript file size. 3. Preload Critical Resources: Use `` to preload critical resources, such as fonts, CSS files, etc. 4.
