Pinned 2026 toolchains (Go 1.26, Rust 1.98/edition 2024, Python 3.14 + uv, Node 24, Zig 0.16, NixOS 26.05), postgres 18 / mongo 8, lockfiles built from, non-root runtimes, .dockerignore, per-project LICENSE, READMEs with the git.devai.io clone line, checkout@v7 CI. Security fixes in the legacy Rust APIs (any-password login, self-assigned admin, hard-coded JWT secret), JWT alg/exp/sub enforcement across the blog series, safe markdown links in the frontends, and many smaller bugs — every project was built, run and exercised end to end. Adds scripts/publish.sh + a CI publish job that splits every folder into its own repo at git.devai.io/templates/<folder>.

# Auth via Clerk
|
|
|
|
Replaces the local email+password auth with [Clerk](https://clerk.com) hosted
|
|
auth. The app stops issuing tokens itself and instead verifies Clerk session
|
|
JWTs (RS256) against your instance's JWKS, checking the issuer.
|
|
|
|
## Setup
|
|
|
|
1. Create an application in the Clerk dashboard and note your instance's
|
|
Frontend API URL (e.g. `https://your-instance.clerk.accounts.dev`) — that is
|
|
the token issuer.
|
|
2. Add the HTTP client to `Cargo.toml`:
|
|
|
|
```toml
|
|
reqwest = { version = "0.13", features = ["json"] }
|
|
```
|
|
|
|
3. Copy `clerk.rs` to `src/clerk.rs` and delete `src/auth.rs` — Clerk hosts
|
|
sign-up and sign-in. In `src/main.rs`, replace `mod auth;` with
|
|
`mod clerk;`, then remove the `/auth/register` and `/auth/login` routes,
|
|
the unused `post` import, and the `jwt_secret` state field along with its
|
|
`AUTH_SECRET` line.
|
|
4. In `src/posts.rs`:
|
|
- import the new extractor: `use crate::clerk::AuthUser;`
|
|
- Clerk user ids are strings (`user_...`), not ObjectIds: change
|
|
`author_id: ObjectId` in `Post` to `author_id: String`, the
|
|
`user_id: ObjectId` parameter of `find_own_post` to `user_id: String`,
|
|
and `post.author_id.to_hex()` in `post_json` to `post.author_id`.
|
|
5. Clerk is the user store now: in `src/db.rs`, remove the `users` field,
|
|
its `email` index and the `User` import.
|
|
6. Set the environment variable:
|
|
|
|
```
|
|
CLERK_ISSUER=https://your-instance.clerk.accounts.dev
|
|
```
|
|
|
|
## Notes
|
|
|
|
- Clients send the Clerk session token as `Authorization: Bearer <token>`
|
|
(`await session.getToken()` in Clerk's frontend SDKs).
|
|
- The JWKS is fetched on first use and cached. A token signed with an unknown
|
|
key id triggers a refetch (at most once a minute), so key rotations need no
|
|
restart.
|
|
- Clerk also puts the requesting origin in the `azp` claim; if browsers from
|
|
other sites could hold your users' tokens, add an `azp: String` field to
|
|
`Claims` and compare it with your frontend's origin.
