Pin Marp CLI and build HTML
Create or open the Marp project
Keep the Markdown source and its local assets in one project directory.Pin the renderer
A pinned development dependency makes future rebuilds easier to compare.Render one HTML file
Choose an.htmloutput path so Marp emits the browser presentation.
npm install --save-dev @marp-team/marp-cli@4.5.0
npx marp slides.md --output build/index.htmlInspect before publishing
test -f build/index.html
wc -c build/index.html
# Optional quick scan for absolute HTTP(S) asset references
grep -Eo '(src|href)="https?://[^"]+"' build/index.htmlOpen the generated file and test left/right navigation, touch or pointer controls, fullscreen, fonts, images, and code blocks. A zero-result URL scan does not replace a browser network check; it only catches simple absolute asset attributes.
Publish or update the deck
slidesfly publish ./build/index.html \
--title "Marp presentation" \
--json
# After claiming or publishing from an account, update the same reader URL:
slidesfly publish ./build/index.html --id YOUR_DECK_ID --jsonCompatibility evidence and boundaries
