Practical articles on code quality, web performance, accessibility, and developer tooling — written by the engineers building CodeAva.
Building custom modals in React? Learn how to trap focus, restore active elements, use WAI-ARIA attributes correctly, and avoid the most common WCAG compliance failures.
Stop fighting timezones. Here is the ultimate cheat sheet for getting, converting, and formatting Unix timestamps across JavaScript, Python, Go, PHP, and SQL databases.
Stop guessing how to block search engines. Learn the exact technical differences between robots.txt, meta robots, and the X-Robots-Tag — and when to use each in your stack.
Still using a static sitemap export? Learn the best practices for dynamic XML sitemaps — clean URL selection, sitemap indexes at scale, accurate lastmod, hreflang for international sites, and a validation workflow that catches problems before Google does.
A misconfigured robots.txt file can block important pages or resources from crawlers without any visible error. Discover the 7 most damaging mistakes, why they happen, and how to fix them before they cost you rankings.
Shipping fast is important. But without periodic code audits, small problems compound into costly outages, security breaches, and engineer burnout. Here is what a good audit actually catches — and why you cannot afford to skip it.
Google’s performance thresholds keep evolving. INP has replaced FID, LCP scoring has tightened, and CLS expectations are stricter than ever. Here is what developers need to know right now.
Automated tools catch roughly 30–40% of accessibility issues. The rest require human judgement. Here is how to build a testing stack that makes the most of both — and integrate it without slowing your team down.
TypeScript’s compiler catches type errors. But a mature static analysis pipeline catches the bugs that types miss entirely — unused exports, cyclomatic complexity, dead code, and security anti-patterns. Here is how to build one.
