Charts look like a small task on a ticket. Then you open the Recharts docs and remember how much setup every chart needs: a config object for labels and colors, axes, a tooltip, a legend, colors that work in dark mode, and a container that resizes properly. Most of us copy all of that from […]

Building a production-ready mobile application used to require a dedicated team of frontend, backend, and DevOps engineers. With modern AI tools, an individual developer can take an idea from concept to the App Store. In a comprehensive new tutorial published on the freeCodeCamp.org YouTube channel, you will learn how to build and publish CodexGram, a […]
For years, real-time asset tracking was a luxury reserved for large enterprises. If you ran a small HVAC company, a regional landscaping crew, or a family-owned construction outfit, the idea of “knowing where every ladder, generator, or pallet of materials is at any given moment” sounded like something only a Fortune 500 logistics team could […]
We just published a new documentary-style video on the freeCodeCamp channel that takes you behind the scenes of a high-energy 24-hour hackathon. Quincy Larson traveled to Hong Kong to serve as a judge at SeaHack. There were more than 250 developers and builders from over a dozen countries. The challenge? Team up, brainstorm, and build […]
Modern software systems are increasingly automated. We automate deployments, infrastructure changes, scaling, incident response, and data pipelines. And now, with AI agents, we are starting to automate operational decisions too. That sounds like progress, but it creates a problem that is easy to miss: We are getting better at executing operations without necessarily getting better […]
Managing massive, rapidly growing datasets efficiently is a critical skill for modern developers. Whether you are tracking API request logs, monitoring IoT fleet telemetry, or building dashboards for AI agents, unoptimized time-series data can quickly slow standard PostgreSQL queries to a crawl. We just posted a new course on the freeCodeCamp.org YouTube channel that will […]
Are you a software engineer looking to master building production-ready AI applications and agentic workflows? We’ve just published a brand new, comprehensive course on the freeCodeCamp.org YouTube channel that will help you prepare for the Claude Certified Developer Foundations (CCDV-F) Certification. Created by Andrew Brown, this course is designed specifically for developers who want to […]
When I published my package on pub.dev, the first few days were exciting as the number of downloads climbed. 201 downloads in a few days! Then something strange happened. The number dropped: 120, then 55. That’s when I knew something wasn’t right. I didn’t break anything. Nothing changed in the package. People did not stop […]
Your workflow uses actions/checkout@v4. Today, that tag points to a vetted release. Tomorrow, a compromised maintainer or attacker moves the tag to malicious code. Your pipeline runs it with access to GITHUB_TOKEN. Third-party Actions are dependencies. A floating tag behaves like an unpinned package dependency. If the reference changes, the workflow can execute different code […]
High-resolution images look great, but they can significantly slow down page load times and consume massive amounts of storage. While backend compression tools are common, building a client-side image compressor offers a massive advantage: privacy. When you process images directly in the browser, no user data ever touches a server. In this tutorial, you’ll learn […]
