2. Default Configuration

Nexus AI uses recommended configuration of Nuxt Image.

image: {
  format: ["webp"],
  screens: { // Screen sizes are from Tailwind CSS
    xs: 320,
    sm: 640,
    md: 768,
    lg: 1024,
    xl: 1280,
    xxl: 1536,
    "2xl": 1536,
  },
},

3. Optimization Techniques

Typical optimization techniques are:

• Using format attribute to control the image format. Default is webp.
• Using fit attribute to control how the image is resized to fit the container.
• Using width and height attributes to control the size of the image. Responsive images are automatically generated.
• Using alt attribute to provide a description of the image for accessibility.
• Using loading attribute to control the load asynchronously or not.
• Using preload attribute to control the preloading behavior of the image.

Here is an example of how to use these attributes:

<NuxtImg
  src="/img/about.jpg"
  width="600"
  height="400"
  format="webp"
  fit="cover"
  :preload="true"
  alt="Hero Image"
  class="rounded-lg"
/>

4. Image Formats and CDN Support

webp is the current most recommended image format for modern browsers. It is supported by all modern browsers and provides a good balance between image quality and file size.

Nexus AI do not use any CDN for images. All images are served from locally using nuxt-image module. Nuxt Image module uses IPX to serve images from static folder.
