npm or npx?

The two commands differ by one letter. Their jobs couldn't be more different.

👉 npm installs packages into your project.
👉 npx downloads a package, runs it, and removes it afterward unless it's already available.

That's why you'll see this:

npx create-vite@latest

instead of:

npm install create-vite

You're only using create-vite once to generate a project. Keeping it installed afterward serves no purpose.

📖 A simple rule works almost every time:

✔️ If your application needs it to run, install it.
✔️ If you only need the tool for a one-time task, run it with npx.

Worm Compromises Over 1,300 npm Packages Including Popular Caching Tools

A self-spreading worm called ChainDrop has compromised more than 1,300 npm packages, including popular ones like Keyv, Cacheable, and flat-cache.

The packages together have around 2 billion monthly downloads. The attack started after a maintainer’s GitHub account was compromised. The malware steals credentials and spreads by publishing new malicious versions.

Developers are urged to check their dependencies and rotate any exposed credentials.

🧠 20 GitHub Repos That Expose What Tutorials Never Taught You

You can build a to-do app in five frameworks and still not know how a database index works. These repos close that gap.

1. computer-science
A full self-taught CS degree curriculum, for anyone who skipped college or forgot what they learned.

2. the-book-of-secret-knowledge
A huge stash of tools, tricks, and one-liners that experienced devs pick up over years, all in one place.

3. system-design-primer
Breaks down how the apps you use every day handle millions of users behind the scenes.

4. build-your-own-x
Walks you through building your own Git, Docker, or database, so the tools you use daily stop feeling like black boxes.

5. linux-insides
A gentle, detailed walkthrough of how the Linux kernel actually works under the hood.

6. professional-programming
Covers everything tutorials skip: engineering practices, architecture, and how real teams ship code.

7. project-based-learning
A list of real projects to build, for when tutorial hell starts feeling too comfortable.

8. you-dont-know-js
JavaScript fundamentals most developers using JS every day have never actually learned.

9. CS-Notes
Clear, structured notes on algorithms, operating systems, networking, and databases in one repo.

10. the-algorithms
Classic algorithms and data structures implemented in almost every language, good for understanding rather than memorizing.

11. free-programming-books
Thousands of free books covering the fundamentals no bootcamp has time for.

12. developer-roadmap
Visual maps of what "knowing" a certain stack really involves, useful when you're not sure what you're missing.

13. system-design-101
Visual explanations of system design concepts, built for people who learn by seeing.

14. coding-interview-university
A study plan built around filling CS gaps, which happens to also prepare you for interviews.

15. awesome-selfhosted
A list of services you can run yourself, good for anyone who's only ever read about infrastructure.

16. realworld
The same production app built in dozens of frameworks, so you can compare how they actually differ.

17. public-apis
Free APIs to build against real, messy data instead of another seeded dummy database.

18. first-contributions
A guided first pull request, for anyone too intimidated to touch someone else's codebase.

19. awesome
The master list of curated resources. When you don't know what you don't know, start here.

20. 30-seconds-of-code
Short, sharp snippets that teach patterns instead of just giving you copy-paste answers.
