SvelteKit Headless WP REST API demo

Work in progress. 👨‍💻

Live: https://sveltekit-headless-wp-rest-demo.vercel.app/

Content is fetched from WordPress demo backend https://nature-blog.mandrasch.eu/. Please use your own backend if you run big tests. The backend API URL can be configured in .env-file.

Local setup

npm install
# Copy .env.example to .env
npm run dev -- --open

Local backend (optional)

See https://github.com/mandrasch/sveltekit-headless-wp-rest-demo-backend and switch in .env-file to the following:

# .env
PUBLIC_WP_REST_API_DOMAIN=https://sveltekit-headless-wp-rest-demo.ddev.site

• Vercel (SSR hosting)
