a base repo for a static site with decapcms (formerly known as netlifycms) & sharp image optimization.
it includes a component for rendering the markdown to html with a custom image component. the image component gets a range of options (an array of sizes, formats, quality, etc.). each page that uses netlifycms for content needs an endpoint in which the markdown is processed.
look to src/routes/post/[slug]/+page.server.ts to see how to set up an endpoint and to src/routes/post/[slug]/+page.svelte to see how to set up the corresponding page. look to src/lib/types.ts to get information about the image options.
for a inspirations on how to set up decapcms look to static/admin/config.yml
