Question 1

How does Fresh compare to Next.js?

Accepted Answer

Fresh offers zero JavaScript by default and island-based hydration, making it faster for initial loads and SEO-friendly, but it's tied to Deno, whereas Next.js has a larger ecosystem, supports Node.js, and offers more features like API routes. Choose Fresh if you're using Deno and prioritize performance, but Next.js if you need broader community support and flexibility.

Question 2

How to add client-side state in Fresh?

Accepted Answer

Use Fresh's island architecture to create interactive components with client-side JavaScript. You can define islands with state management using Preact hooks or compatible Deno libraries, but note that full-page state might require server-side logic or careful island design.

Question 3

Is Fresh good for SEO?

Accepted Answer

Yes, Fresh is excellent for SEO because it defaults to zero JavaScript on the client, ensuring content is fully renderable by search engines. The island-based hydration allows dynamic elements without compromising crawlability.

Question 4

Can I use Fresh with React components?

Accepted Answer

Fresh uses Preact under the hood, which is compatible with most React components, but you may need to adapt code for Preact's smaller footprint. The README doesn't specify React integration, so testing with Deno's module system is recommended.

Question 5

What are the deployment options for Fresh?

Accepted Answer

The easiest option is Deno Deploy, as recommended in the README, but you can also self-host using Deno CLI on any server. However, deployment outside Deno's ecosystem requires additional configuration and might not be as streamlined.

Question 6

Fresh vs Astro: which is better for static sites?

Accepted Answer

Both prioritize performance with partial hydration, but Fresh is Deno-native and emphasizes zero JS by default, while Astro is more agnostic with support for multiple frameworks and static generation. Pick Fresh for Deno integration, but Astro if you need flexibility with other tools.

Question 7

How to handle authentication in Fresh?

Accepted Answer

Authentication in Fresh typically relies on server-side logic since it's a server-first framework. Use Deno's security features or third-party OAuth libraries compatible with Deno, but the ecosystem is limited compared to Node.js-based solutions.
