How to handle update logic in server side when using SvelteKit?

When building applications with SvelteKit, you may encounter the need to handle update logic on the server side. This can be useful for scenarios like updating a database or triggering external API calls. In this blog post, we will explore two solutions to handle update logic in SvelteKit on the server side.

Solution 1: Using an API endpoint

One way to handle update logic in SvelteKit is by creating an API endpoint on the server side that can be called from the client side. This allows you to separate the update logic from the UI components and keep it on the server.

To implement this solution, you can follow these steps:

Create an API endpoint in your server code (e.g., using Node.js and Express) that handles the update logic.
In your SvelteKit component, make an HTTP request to the API endpoint when the update action is triggered.
Handle the response from the server and update the UI accordingly.

Here’s an example code snippet to illustrate this solution:

// Server-side API endpoint (e.g., using Express)
app.post('/api/update', (req, res) => {
  // Handle update logic here
  // e.g., update the database or trigger external API calls
  
  // Return a response to the client
  res.json({ message: 'Update successful' });
});

// SvelteKit component

Solution 2: Using server functions

SvelteKit provides server functions that allow you to run code on the server side. You can leverage this feature to handle update logic in a server function.

To implement this solution, you can follow these steps:

Create a server function in your SvelteKit project that handles the update logic.
Call the server function from your SvelteKit component when the update action is triggered.
Handle the response from the server function and update the UI accordingly.

Here’s an example code snippet to illustrate this solution:

// Server function (e.g., in src/routes/api/update.js)
export async function post() {
  // Handle update logic here
  // e.g., update the database or trigger external API calls
  
  // Return a response to the client
  return {
    body: { message: 'Update successful' }
  };
}

// SvelteKit component

These are two solutions to handle update logic in SvelteKit on the server side. Choose the one that best fits your project requirements and enjoy building powerful applications with SvelteKit!
