Server-Side Code Placement

TODO: collapasable, copyable, download, etc

In a sveltekit project, is there a place to put code that limits it to being run on the server side only?Yes, in a SvelteKit project, you can put code that is intended to run only on the server side in specific locations to ensure it doesn't get executed on the client side. Here are the primary ways to do this:

1. src/hooks.ts (or src/hooks/index.ts):

   • SvelteKit uses hooks for various server-side operations. You can place server-only code in the handle hook, which can modify requests and responses, or in other server-specific hooks like getSession.

2. Endpoint Scripts:

   • Files in the src/routes directory can be used to create API endpoints. These scripts run only on the server. You can write server-side logic here, which will be triggered when the corresponding route is accessed.

3. $lib Directory:

   • Although the $lib directory is accessible from both the client and server, you can use dynamic imports to ensure that certain modules are only loaded on the server. For instance, importing a module inside an endpoint script or a server-side hook ensures it's only used server-side.

4. Environment Checks:

   • You can use environment checks within your code to determine if the code is running on the server or client. For example, checking if typeof window === 'undefined' can tell you if the code is running in a non-browser (likely server-side) environment.

5. svelte.config.js:

   • While not a place to write your server-side code, this configuration file can influence how your SvelteKit application is built, including how server-side and client-side code is separated.

Remember that while SvelteKit supports server-side rendering and logic, it's primarily a framework for building universal (isomorphic) applications where code can run on both the server and client. Therefore, being explicit about where server-only code resides is crucial for both security and functionality.
