Question 1

How do I handle client-side routing in VanJS?

Accepted Answer

VanJS core doesn't include routing; you need to use community add-ons like vanjs-router or Van Cone for SPA functionality. These provide routing solutions but add external dependencies and may require additional setup.

Question 2

VanJS vs React: which is better for a small project?

Accepted Answer

VanJS is ideal for ultra-lightweight, toolchain-free projects where bundle size is critical, as it's 50-100x smaller. React is better if you need a vast ecosystem, JSX, and established patterns for scaling, but comes with more overhead.

Question 3

How to create a reusable component in VanJS?

Accepted Answer

Define a pure JavaScript function that returns DOM elements using van.tags. For example: const MyComponent = (props) => div(p(props.text)). Then use it like van.add(document.body, MyComponent({text: 'Hello'})).

Question 4

Does VanJS work with Node.js for server-side rendering?

Accepted Answer

Yes, through Mini-Van, a separate library for server-side rendering. It allows you to generate HTML on the server and hydrate it on the client, improving performance and SEO, as used on the vanjs.org site.

Question 5

Can I use TypeScript with VanJS?

Accepted Answer

Yes, VanJS provides first-class TypeScript support with .d.ts files for type-checking and IntelliSense. Refer to the Download Table on the website to select the appropriate type definitions for your setup.

Question 6

What are the limitations of VanJS compared to Vue?

Accepted Answer

VanJS is much smaller and simpler but lacks Vue's built-in features like Vue Router, Vuex for state management, and a comprehensive component system. It's more minimalist, requiring add-ons for advanced functionality, which can fragment the ecosystem.
