Today we will take a beginner-friendly look at What Is SvelteKit and Why Do We Need SvelteKit?
While Svelte alone gives you a very good development experience, you still have to decide on how you want to ship your application to the user. The classical approach would be to take your favourite module bundler like Rollup and bundle your code into one big, fat JavaScript file. Then, you can call it from a very basic HTML document, like so:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
...
</head>
<body>
<div id="app" />
<script src="dist/bundle.js"></script>
</body>
</html>
While this is absolutely legit, the user’s experience might not be ideal.
First of all, instead of serving an almost empty HTML file to the client, SvelteKit already comes with all the HTML elements you need for the first page view. The benefits are faster page loads and SEO boosts. There are two ways SvelteKit does this: prerendering and server-side rendering. I’ll explain both in more detail below till then stay tuned:)

Pages and Layouts in Nextjs- When building projects with Next.js, we typically create an entire user interface by assembling isolated components. However, some parts of the interface require the same code snippets across multiple routes — for example, the navigation header, footer, and sidebar. To manage this, we use layouts to structure the interface in a way that contains shared code snippets. Next.js recommends starting a new project with the App Router. However, we’ll discuss how to implement layouts and nested layouts with the Pages Router for users who have yet to migrate to the new Next.js routing system.
How to Parse JSON in Dart/Flutter Parsing JSON is a very common task for apps that need to fetch data from the Internet. And depending on how much JSON data you need to process, you have two options: write all the JSON parsing code manually automate the process with code generation Encoding and Decoding JSON When a JSON response is sent over the network, the entire payload is encoded as a string. But inside our Flutter apps, we don't want to extract the data from a string manually:
