code-nav.cn “编程导航” is positioned as a one-stop programming learning and exchange community for programmers, providing zero-to-one programming learning routes, enterprise-level project practice, and learning交流.

The site includes sections such as Free Tutorials, Project Practice, Algorithm Learning, Mock Interviews, Interview Practice, AI Learning, Programming Tutorials, Learning Routes, Project Tutorials, Job Search Guides, and AI Tutorials. It covers topics including Java development, programming languages, frontend development, backend development, databases, AI, mobile development, development tools, computer fundamentals, software testing, operations and deployment, and big data.

The available source material does not show that it is an open-source or self-hostable product, so there is no public basis for self-deployment requirements, server resource requirements, or installation steps. Chinese users may have a smoother experience; if building a similar site, consider ICP filing, WeChat / mini-program ecosystem adaptation, and support for domestic cloud, object storage, payment, and other service providers.
