A practical guide to building a reliable invoice generation pipeline, covering numbering, taxes, PDF rendering, and the edge cases that bite you in production.
Generating PDFs with Chinese, Japanese, or Korean text looks easy until you ship it. Here's what actually breaks — font subsetting, encoding, vertical text, and fallback chains — and how to fix each.
A practical guide to handling rate limits, backoff, and quotas when generating PDFs and documents through an API, with patterns you can drop into production.
Embedding logos and images in generated PDFs sounds trivial until a hotlinked asset 404s in production. Here's how to do it reliably across formats, resolutions, and rendering engines.
A practical guide to protecting generated PDFs with encryption, visible and invisible watermarks, and short-lived access controls — with code you can use today.
A practical walkthrough for building a lean receipt generation microservice using a template-based PDF API, with retries, idempotency, and storage considerations.
Embedding images in PDFs sounds trivial until a logo renders as a broken icon on a customer invoice. Here's how to get it right across formats, sources, and rendering engines.
Rendering Arabic, Hebrew, and Urdu in PDFs breaks in subtle ways: reversed digits, broken ligatures, mangled bidi runs. Here's what actually works.
Embedding images in generated PDFs sounds trivial until logos go missing, resolutions blur, or renders time out. Here's how to do it reliably across common PDF pipelines.
A step-by-step guide to building a lean receipt generation microservice in Node.js that handles templating, PDF rendering, and storage without the usual boilerplate.
Embedding images in PDFs sounds trivial until a logo goes missing in production. Here's how to make image rendering deterministic across formats, sources, and runtimes.
A practical walkthrough for building a document automation pipeline using a REST API, covering templates, queueing, storage, and delivery.
A practical guide to handling rate limits, retries, and quota budgets when generating PDFs and other documents through an API — without blowing up production.
The European Accessibility Act takes effect June 2025, and PDFs are squarely in scope. Here's what backend developers need to know about metadata, tagging, and PDF/UA compliance.
wkhtmltopdf served us well for a decade, but it's unmaintained and painful to run in production. Here's how to migrate to a modern PDF API without rewriting your templates.
