JAMstack is a modern front-end development architecture concept based on JavaScript, APIs and Markup, and Astro is its representative framework. It improves performance and maintainability by pre-built static pages, supports multi-frame component development and outputs pure HTML. Astro's core advantages include partial hydration, lightweight output, multi-frame support, Markdown integration and convenient deployment. 1. Install Node.js; 2. Run npm create astro@latest to create a project; 3. Select the plug-in and install the dependencies; 4. Start the development server. In actual development, attention should be paid to SEO settings, picture optimization, global style management, data acquisition and third-party library compatibility.

JAMstack has become a very popular architectural pattern in modern front-end development, especially in combination with frameworks like Astro. It achieves faster loading speed and better maintainability by pre-building static pages and reducing dependence on server-side rendering.

What are JAMstack and Astro?

JAMstack is not a specific tool or framework, but a development concept that emphasizes the use of JavaScript, APIs, and Markup to build websites. Its core strength lies in performance, security, and scalability.

Astro is a JAMstack-based framework that has emerged in recent years. It focuses on static site generation (SSG), supports component development of a variety of front-end frameworks (such as React, Vue, Svelte). At the same time, it can output pure HTML during construction, improving the loading speed of the first screen.

Why choose Astro for front-end development?

A highlight of Astro is Partial Hydration, which means that it only loads JavaScript where interaction is needed and remains static elsewhere, which not only retains the speed advantage of static websites, but also allows for the flexibility to add dynamic functions.

• Lightweight output : The final output HTML file is small in size and fast loading.
• Multi-framework support : You can mix React, Vue and other components in the same project.
• Powerful Markdown support : suitable for document or content websites.
• Out-of-the-box deployment experience : It can be easily deployed to platforms such as Vercel, Netlify, etc.

If you are working on a blog, official website or document site, Astro can be said to be one of the most worth trying options at the moment.

How to start an Astro project?

The process of creating an Astro project is very simple, the basic steps are as follows:

• Install Node.js (LTS version is recommended)
• Run npm create astro@latest my-astro-site
• Select the required feature plug-ins (such as Tailwind CSS, React support, etc.)
• Install dependencies and start the local development server

 cd my-astro-site
npm install
npm run dev

The directory structure of Astro is clear and easy to understand, and the files under src/pages/ will be automatically converted to routes. For example, create a src/pages/about.astro file, which can be accessed via /about .

You can use HTML template syntax directly in the .astro file, or you can introduce modules of components or other frameworks.

What details should be paid attention to in actual projects?

Although it is easy to get started with Astro, there are still several key points to pay attention to in real projects:

• SEO settings : You can set page title, description, etc. through the <meta> tag or built-in components provided by Astro.
• Image optimization : Astro supports native <img alt="Frontend Development with JAMstack Frameworks (e.g., Astro)" > tags, but it is recommended to use <image></image> components for lazy loading and format optimization.
• Global style management : CSS can be written in src/styles/ directory and introduced uniformly in the layout components.
• Data acquisition : Astro supports asynchronous data acquisition for static generation, and can use fetch() or read local JSON files.
• Third-party library compatibility : Some DOM-dependent JS libraries may not run at build time and need to determine whether they are suitable for use in Astro.

For example, if you intend to connect to Google Analytics, you usually choose to load scripts on the client side. At this time, you need to use the <script></script> tag and make sure that it is executed only in the browser environment.

Basically that's it.
