2// Writes the Wrangler configs a self-hosted g1t runs with, derived from the
3// hosted ones, so the two never drift apart.
4//
5// Each hosted service's wrangler.jsonc is read and changed only where
6// Cloudflare-only things live:
7//
8// - account, routes, placement, observability and builds are dropped;
9// - ARTIFACTS (git storage) becomes a service binding to workers/artifacts,
10// which keeps repositories in the git store (gitstore/server.mjs);
11// - EMAIL (Email Sending) becomes a service binding to workers/mail;
12// - the packages service keeps files in S3-compatible storage (RustFS)
13// instead of R2, the repos service its nightly backups (a bucket of
14// their own, BACKUP_S3_BUCKET), and the docs service the files in pages
15// (DOCS_S3_BUCKET);
16// - services that are off in this phase (agents, the context hub, the
17// g1t.page dispatcher, model proxy) are bound to workers/off instead, and
18// events stop queueing work for them;
19// - URLs that name g1t.sh name PUBLIC_URL instead, and billing is free.
20//
21// Usage: node configs.mjs [outDir]
22// Environment: PUBLIC_URL, GITSTORE_URL, GITSTORE_SECRET, MAIL_URL,
23// ACTIONS_KEY, INTEGRATIONS_KEY, WEBHOOKS_KEY, IDENTITY_KEY, USERCONTENT_KEY,
24// USERCONTENT_URL,
25// PACKAGES_TOKEN_SECRET, S3_ENDPOINT, S3_BUCKET, BACKUP_S3_BUCKET, DOCS_S3_BUCKET, S3_REGION,
26// S3_ACCESS_KEY_ID, S3_SECRET_ACCESS_KEY, S3_PUBLIC_ENDPOINT, and optionally
27// your own GitHub App: GITHUB_APP_ID, GITHUB_APP_SLUG, GITHUB_APP_CLIENT_ID,
28// GITHUB_APP_CLIENT_SECRET, GITHUB_APP_PRIVATE_KEY, GITHUB_APP_WEBHOOK_SECRET.
29//
30// The output is for `wrangler dev` (see start.sh): every Worker in one
31// workerd, the site first, with D1, KV and Queues kept on disk.
