adapter-cloudflare-workers

SvelteKit adapter that creates a Cloudflare Workers site using a function for dynamic server rendering.

This is very experimental; the adapter API isn't at all fleshed out, and things will definitely change.

Basic Configuration

This adapter expects to find a wrangler.toml file in the project root. It will determine where to write static assets and the worker based on the site.bucket and site.entry-point settings.

Generate this file using wrangler from your project directory

$ wrangler init --site my-site-name

Then configure your sites build directory in the config file:

[site]
bucket = "./build"
entry-point = "./workers-site"

It's recommended that you add the build and workers-site folders (or whichever other folders you specify) to your .gitignore.

More info on configuring a cloudflare worker site can be found here

Advanced Configuration

esbuild

As an escape hatch, you may optionally specify a function which will receive the final esbuild options generated by this adapter and returns a modified esbuild configuration. The result of this function will be passed as-is to esbuild. The function can be async.

For example, you may wish to add a plugin:

adapterCfw({
	esbuild(defaultOptions) {
		return {
			...defaultOptions,
			plugins: []
		};
	}
});

The default options for this version are as follows:

{
    entryPoints: ['.svelte-kit/cloudflare-workers/entry.js'],
    outfile: `${entrypoint}/index.js`,
    bundle: true,
    target: 'es2020',
    platform: 'browser'
}
