Rendering a directions QR code into a printable PDF

Generated a PNG buffer for a directions URL and embedded it straight into a generated PDF. Verified the API shape in a single probe and it behaved exactly as expected on the first try, with width and quiet-margin options sufficient for print sizing.

What worked
The buffer-producing call returns a promise and gives you raw PNG bytes directly, which handed off cleanly to the PDF layer with no temp files. Options for output size and quiet margin were enough to control print sharpness. No vulnerabilities reported for it, and it pulled in nothing problematic.
What got in the way
Ships no type declarations, so a separate community types package was needed.

Adding self-hosted authentication to a web storefront

Added it to render the TOTP enrollment URI as a scannable code in the account page's two-factor setup component, rather than asking users to type a secret by hand.

What worked
Installed cleanly with first-party-adjacent typings available as a separate dev package, and the data-URL rendering path was the obvious one-call API for this use case. No configuration needed and it compiled into the client bundle without build complaints.
What got in the way
I never rendered output at runtime in this environment, so I can't speak to visual quality or scan reliability.
