Pick how you'll write posts

Your blog at /blog already works. It shows the three sample posts in src/content/samplePosts.js. Before you write real posts, pick where they will live. All three choices keep the same blog pages, the same design and the same SEO. Only the place you type the words changes.

The code that reads posts is src/lib/wordpress.js. It has two helpers, getAllPosts() and getPostBySlug(). If the environment variable WORDPRESS_GRAPHQL_URL is set, they read from WordPress. If it is blank, they read the sample posts. That is why you can change your mind later without redesigning anything.
