Configuration

Every deploy setting, Worker variable and binding, and the permissions the deploy token needs.

Deploy settings

alchemy.run.ts reads these from the environment. All are optional except the Cloudflare credentials.

Variable	Default	Meaning
`CLOUDFLARE_API_TOKEN`	required	The deploy token
`CLOUDFLARE_ACCOUNT_ID`	required	The account to deploy to
`PARSEW_DOMAIN`	unset	A zone in the account. Set, the Worker serves `app.<domain>` and `logo.<domain>`; unset, only `workers.dev`. Every hostname becomes a Workers custom domain: delete any DNS record those names already have first, since Alchemy can’t take them over
`PARSEW_APP_HOST`	`app.<domain>`	The dashboard’s hostname
`PARSEW_IMAGES_HOST`	`logo.<domain>`	The image API’s hostname
`PARSEW_SITE_HOST`	unset	Serves the landing page there, with the docs at `/docs` (parsew.com’s deployment). Unset, the docs are on the app host
`PARSEW_REDIRECT_HOSTS`	`www.<domain>` (with a site host)	Comma-separated hostnames that 301 to the site with path and query, through a zone redirect rule that runs before the Worker. Empty disables
`PARSEW_DOCS_HOST`	`docs.<domain>` (with a site host)	An old docs hostname: the Worker 301s it to `<site>/docs<path>`. Empty disables
`PARSEW_EMAIL_FROM`	unset	Sender address for the “you reached your limit” email and password resets, through Cloudflare Email Sending on the zone. Unset, no email is sent and “Forgot password” is hidden
`PARSEW_ALLOW_SIGNUP`	`true`	`false` closes sign-up (existing accounts keep working)
`PARSEW_AUTUMN_SECRET_KEY`	unset	Turns on hosted billing through Autumn. Leave unset when self-hosting
`PARSEW_WORKER_NAME`	`parsew` (`parsew-<stage>` outside prod)	The Worker’s name, and the prefix of every resource

Create a custom account API token with:

Account: Workers Scripts Edit, D1 Edit, Workers R2 Storage Edit, Account API Tokens Edit (mints the Worker’s read-only Analytics Engine token), Account Settings Read, Secrets Store Edit (Alchemy’s state store keeps its bearer token there).
With PARSEW_DOMAIN, on that zone: Zone Read, DNS Edit, Workers Routes Edit, SSL and Certificates Edit, and with a site host Single Redirect Edit (the www. redirect rule).
With PARSEW_EMAIL_FROM: Email Sending Edit.

Set by Alchemy; listed for reference and for local development (.dev.vars).

Name	Kind	Meaning
`APP_URL`	variable	The dashboard’s origin (on workers.dev: the Worker’s own URL)
`IMAGES_URL`	variable	The image API’s base URL; unset means `APP_URL` + `/i`
`SITE_URL`	variable	The landing page’s origin; unset serves no landing page
`DOCS_HOST`	variable	The old docs hostname (`docs.parsew.com`) that 301s to `SITE_URL/docs`; set only with a site
`AE_DATASET`	variable	The Analytics Engine dataset’s name, for the SQL API
`CF_ACCOUNT_ID`	variable	The account, for the SQL API
`ALLOW_SIGNUP`	variable	`false` closes sign-up
`EMAIL_FROM`	variable	The sender address; unset turns email off
`BETTER_AUTH_SECRET`	secret	Signs sessions; generated once by Alchemy
`CF_ANALYTICS_TOKEN`	secret	Account Analytics Read, minted by Alchemy
`AUTUMN_SECRET_KEY`	secret	Hosted billing; unset turns billing off
`AUTUMN_API_URL`	variable	Autumn’s API base (tests point it at a stand-in); default `https://api.useautumn.com/v1`

Binding	Resource
`DB`	D1 database
`SOURCES`	R2 bucket
`USAGE`	Analytics Engine dataset
`IMAGES`	Images binding
`ASSETS`	The built dashboard, landing page and docs
`EMAIL`	Email Sending, only with `PARSEW_EMAIL_FROM`

Why each exists is in Architecture.
