Create a Cloudflare Workers site:

`bash
wrangler init --site my-site-name
`

Entries in the wrangler.toml file are required for [site.bucket] and [site.entry-point].

[site.bucket] should be set to ./build for the default SvelteKit build process.

This adapter will create your Cloudflare Worker script at publish time, and output
the results in [site.entry-point] (defaults to workers-site).

_Note:_ Do not place any custom code in [site.entry-point] as it will be overwritten at publish time.

Required environment variables:

- AUTH0_DOMAIN - Domain for your Auth0 application (must include scheme, e.g. https)
- AUTH0_CLIENT_ID - Client ID for your Auth0 application
- AUTH0_CLIENT_SECRET - Client secret for your Auth0 application (encrypt or use wrangler secret)
- AUTH0_CALLBACK_URL - Callback URL for your Auth0 application. Must be your worker's base URL with /auth as the path.
- AUTH0_LOGOUT_URL - Logout URL for your Auth0 application. Must be your worker's base URL with /logout as the path.
- SALT - A secret string used to encrypt user sub values
import adapter from 'svelte-kit-adapter-cloudflare-workers-auth0';

#### Cloudflare KV configuration

Create a Cloudflare KV store with the name AUTH_STORE.

`
wrangler kv:namespace create AUTH_STORE
`

Copy the output of this command into your wrangler.toml file.

Full example with different environments:

`toml
type = "javascript"
account_id = ''
usage_model = ''
compatibility_flags = []

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

[build]
command = "npm install && npm run build"

[build.upload]
format = "service-worker"

[env.dev]
workers_dev = true
name = ''
route = 'https://..workers.dev/*'
kv-namespaces = [
{ binding = "AUTH_STORE", id = "" }
]

[env.production]
zone_id = ''
name = ''
route = '/*'
kv-namespaces = [
{ binding = "AUTH_STORE", id = "" }
]

[secrets]

AUTH0_DOMAIN

AUTH0_CLIENT_ID

AUTH0_CLIENT_SECRET

This adapter is largely a direct copy of @sveltejs/adapter-cloudflare-workers, with support for authentication and basic authorization on the 'server'-side.

Auth0 support was based on the official Cloudflare Workers Auth0 tutorial.
