Longform — A Home for Your Writing

Words first. Everything else second.

Longform is a real, buildable Hanzo app: a minimalist personal essay blog you fork on hanzo.app and deploy live on Hanzo Cloud. Write long reads, publish them, and give readers a distraction-free reading column with an honest reading-time estimate and an index of everything you've written, by year.

• UI — @hanzo/gui (the Hanzo design system) under Vite + React 19. No second UI kit, no Tailwind — set like a book page in a warm-paper editorial palette.
• Auth — @hanzo/iam, OAuth2 PKCE against hanzo.id. No local passwords — IAM owns every credential interaction.
• Data — @hanzo/base, the IAM-native, org-scoped data plane. Your essays are real Base rows, private to your org until you publish.

The three views

• Index — a table of contents. Drafts gather at the top while you write them; published essays fall under a year marker, newest first. Each row shows the title, an optional subtitle, and a footnote-gray date + reading time.
• Reading — a single narrow column (~66ch) set in a book serif with generous leading, a drop-cap on the opening paragraph, and quiet metadata.
• Editor — title, subtitle, and a markdown body, with a live word / reading estimate and a Draft ⇄ Published toggle.

Run it

npm install
npm run dev        # http://localhost:5173
npm run build      # tsc --noEmit && vite build  ->  dist/
npm run preview    # serve the production build (SPA fallback on)

Out of the box it runs against live Hanzo (hanzo.id + api.hanzo.ai) — no config needed to see the landing + sign-in flow. Copy .env.example to .env to point at a different environment.

Environment contract

Only VITE_-prefixed vars reach the browser (this is a static SPA — there is no server). Defaults in parentheses.

Var	Purpose
VITE_HANZO_IAM_URL (https://hanzo.id)	OIDC issuer.
VITE_IAM_CLIENT_ID (hanzo-app)	IAM application (<org>-<app>). Its redirect-URI list must allow this deploy's /auth/callback. The deploy provisions a per-app client.
VITE_HANZO_REDIRECT_URI (${origin}/auth/callback)	PKCE redirect.
VITE_HANZO_BASE_URL (https://api.hanzo.ai)	Browser-reachable Hanzo Base data plane. Deploy injects the provisioned URL.

How auth works — ambient IAM

login() starts an OAuth2 PKCE S256 redirect to hanzo.id; hanzo.id returns to /auth/callback, where handleCallback() exchanges the code for tokens (stored in localStorage, refresh-aware via offline_access). Every deployed app is a static site at <slug>.hanzo.app; there is no server token — the SPA authenticates the user in the browser and carries the resulting IAM JWT to Base. The client id is read from VITE_IAM_CLIENT_ID (fallback hanzo-app).

How data works — Base from schema.sql

schema.sql is the app's databaseSchema (SQL DDL). On publish, Hanzo Cloud translates each CREATE TABLE into a Hanzo Base collection (provisionBaseFromDDL, additive + idempotent). Base manages id/created/updated, stamps owner+org from the verified IAM principal, and scopes every row to the caller's org (@request.auth.org_id = org) — a teammate in your org sees the row; other orgs cannot. At runtime the views read/write the essays collection through @hanzo/base/react (useQuery/useMutation) carrying the IAM token. collections + essay_collections are provisioned for grouping essays into series.

Deploy — Hanzo Cloud

hanzo.yml declares a static build (npm run build → dist/, served at <slug>.hanzo.app) plus the Base schema to provision and the env to inject. Do not build a container image locally — Hanzo Cloud owns builds and deploys. CI here only proves the template compiles green.
