Goyapp

Online poster editor. Log in, pick a template, drag any element freely on a canvas, export to SVG / PNG / JPG / PDF.

Stack

• apps/web — Next.js 15 (App Router), TypeScript, Tailwind, shadcn/ui, Auth.js v5, Prisma, Fabric.js v6
• apps/pdf-worker — Fastify + Puppeteer (PDF rendering from Fabric SVG)
• Postgres 16 — users, templates, projects
• MinIO — S3-compatible storage for user-uploaded assets
• pnpm workspaces + Docker Compose

Quick start (Docker — recommended)

cp .env.example .env
docker compose up --build

Then open http://localhost:3000. On first boot the web container runs Prisma migrate + seed automatically (3 starter templates + a demo user demo@goyapp.local / demo1234).

MinIO console: http://localhost:9001 (user/pass from .env).

Local dev (no Docker)

pnpm install
# Start just the infra
docker compose up db minio pdf-worker -d
cp .env.example .env
pnpm --filter @goyapp/web db:push
pnpm --filter @goyapp/web db:seed
pnpm dev

How export works

• SVG / PNG / JPG — rendered client-side directly from the Fabric canvas (toSVG, toDataURL).
• PDF — the web app POSTs the Fabric-exported SVG to pdf-worker, which renders it in headless Chromium at the canvas's native size and returns a PDF. Fonts are embedded by Chromium, so what you see is what you get.
