In the world of web development, Next.js has quickly emerged as a powerful tool for building React applications. With its focus on performance and developer experience, Next.js provides a seamless way to create dynamic web applications. One of the key features of Next.js is its support for various tags, such as source, link, and image tags, which play a crucial role in enhancing the functionality and aesthetics of your web application. In this blog post, we will dive deep into these tags, exploring their usage and benefits in Next.js.

Source Tag in Next.js

The source tag in Next.js is used to specify the location of an external resource, such as a video or audio file, to be embedded in the webpage. It is commonly used in conjunction with the <video> or <audio> tags to provide a fallback mechanism for browsers that do not support these tags natively. The source tag accepts several attributes, including src, type, and media, which allow you to specify the URL of the resource, its MIME type, and the media query for which the resource is intended, respectively.

Here's an example of how you can use the source tag in Next.js:

<video controls>
  <source src="/video.mp4" type="video/mp4" />
  Your browser does not support the video tag.
</video>

In this example, the source tag specifies the location of the video file (video.mp4) and its MIME type (video/mp4). If the browser supports the video tag, it will display the video; otherwise, it will display the fallback message.

The link tag in Next.js is used to define relationships between the current document and external resources. It is commonly used to link stylesheets, icons, and other resources to the webpage. The link tag accepts several attributes, including rel, href, and type, which allow you to specify the relationship of the linked resource, its URL, and its MIME type, respectively.

Here's an example of how you can use the link tag in Next.js to link a stylesheet:

<link rel="stylesheet" href="/styles.css" />

In this example, the link tag links the styles.css stylesheet to the webpage, allowing you to apply styles to the document.

Image Tag in Next.js

The image tag in Next.js is used to embed images in the webpage. It is similar to the <img> tag in HTML but provides additional features, such as automatic optimization and lazy loading, to improve the performance of your web application. The image tag accepts several attributes, including src, alt, width, and height, which allow you to specify the URL of the image, its alternative text, and its dimensions, respectively.

Here's an example of how you can use the image tag in Next.js:

<Image
  src="/image.jpg"
  alt="A beautiful image"
  width={500}
  height={300}
/>

In this example, the image tag embeds the image.jpg image in the webpage with the specified alternative text and dimensions.
