What is the difference between full and runtime only builds in Vuejs explain with example?

Here's a breakdown of the differences between full and runtime-only builds in Vue.js:

Full Build:

• Includes template compiler: This allows for template options in components, where templates are directly written in HTML-like syntax within <template> tags.

• General-purpose usage: Suitable for direct inclusion in a browser via a CDN or as a standalone script, as well as for development environments where template compilation is needed.

• Larger file size: Contains the template compiler, increasing the bundle size.

Example:

HTML

<script src="https://unpkg.com/vue@3"></script> ```

**Runtime-Only Build:**

- **Excludes template compiler:** Templates must be pre-compiled into JavaScript render functions during the build process.
- **Optimized for production:** Ideal for production builds where template compilation has already occurred, resulting in smaller bundle sizes and faster execution time.
- **Requires pre-compilation:** Templates cannot be directly written in `<template>` tags; they need to be pre-compiled into render functions.

**Example:**

```vue
<script setup>
const h = Vue.h; // Access render function from Vue
</script>

<template> <div>Hello, world!</div>
</template>

Key Considerations:

• Bundle Size: Runtime-only builds are smaller, improving initial load time.

• Template Compilation: Full builds allow runtime compilation, while runtime-only builds require pre-compilation.

• Development Environment: Full builds are often used in development for convenience.

• Production Environment: Runtime-only builds are preferred for optimized performance.

When to Use Each:

• Full Build:

• Development environments

• Simple projects without bundle size concerns

• CDN or standalone usage

• Runtime-Only Build:

• Production environments

• Bundle size optimization

• Using build tools like Vue CLI

Remember:

• Choose the build that aligns with your project's needs and deployment strategies.

• Prioritize runtime-only builds for production to enhance performance.
