Dropping Sanity, shipping MDX

Sanity is out. The stack is simpler now.

Posts live as .mdx files in src/content/journey/. No external CMS, no API calls at build time, no dashboard to log into. The Astro content collection handles schema validation; the GitHub repo is the source of truth.

What changed

Content schema

Two collections, defined once in src/content.config.ts:

const journey = defineCollection({
  loader: glob({ pattern: '**/*.mdx', base: './src/content/journey' }),
  schema: z.object({
    title: z.string(),
    phase: z.string(),
    publishedAt: z.string(),
    excerpt: z.string(),
    tags: z.array(z.string()).optional(),
    draft: z.boolean().default(false),
  }),
})

const work = defineCollection({
  loader: glob({ pattern: '**/*.mdx', base: './src/content/work' }),
  schema: z.object({
    title: z.string(),
    client: z.string(),
    year: z.number(),
    cover: z.string().optional(),
    featured: z.boolean().default(false),
    draft: z.boolean().default(false),
  }),
})

Images

Assets go to Cloudflare R2 via a CDN subdomain. Bucket: artupinad, folder structure: artupinad/journey/, artupinad/work/, artupinad/design/. Zero egress cost — images are served directly from the CDN, not proxied through Netlify.

Automation still works

The pipeline from MASTERPLAN to live post is unchanged from the outside:

tick checkbox in MASTERPLAN.md
  → push to dani-brain/main
  → GitHub Action triggers (path filter: MASTERPLAN.md)
  → parse-masterplan.py diffs newly ticked items
  → generate-update.py calls Claude API → writes MDX
  → commits to packages/web/src/content/journey/
  → opens PR in danidee/artupinad
  → Netlify preview URL sent via ntfy
  → merge → live on /journey

The difference: instead of committing a Sanity document via their write API, the script commits an .mdx file via GitHub’s API. One fewer external service in the chain.

Monorepo consolidation

danidee/artupinad is now a proper npm workspaces monorepo:

• packages/web → artupinad.com (Astro + MDX)
• packages/design-system → storybook.artupinad.com (Storybook)

Both deploy independently via Netlify with repo-scoped deploy keys. The old danidee/web and danidee/design-system repos are archived.
