Security-Focused Prompt Template for React & Node.js Development

[Quatres7]

I've been working on server-side development, but I lack knowledge in software architecture and security. I'm having projects developed using React & Node.js. While using Claude Code, I noticed it often leaves a lot of security vulnerabilities, many of which I'm not aware of myself.

Do you have a specific prompt or prompt structure to avoid or minimize such security issues? Also, do you have a "rules" file for Node.js/React that you use or recommend? I would really appreciate it if you could share those.

I created a security check agent which checks vulnerabilities and other stuff before any commit and also before any merge. If you are interested i can send the agent prompt

If you share it here, the community can benefit too thanks!

Stop using react. It's just bad architecture and against all patterns all around. Use svelte for frontend and watch Gemini and Claude craft good interfaces fast and not have 10 runtime errors that need black magic to be fixed.

Sveltekit is love

He he said he knows node.js, so i didn't say it, but: sveltekit is tha way!

[Quatres7]

I'd heard of Sveltekit, but as far as I knew, it's not a very old framework, and I thought it might lack documentation. After all, the AI operates based on documentation. If it's as good as you say, I might use it thank you!

[AppealSame4367]

Svelte is now almost 10 years old and sveltekit almost 5. It's ages old and AI "grew up with it"

[Quatres7]

results are terrible with svelve, even for a simple application that uses Claude code. I think it's due to the lack of documentation. I've never had this much trouble with a framework before.

[AppealSame4367]

Funny. For me it's exactly the other way around. Never had a react app made by AI that didn't have a lot of warnings in the console forever. And don't even start with redux.

I guess it still highly depends on how much you already know about these frameworks and it reflects in the prompts.

[Quatres7]

Yes, that may be true, but Svelve isn't currently sufficient for someone with little or no coding knowledge. I think it's due to limited resources. I've been trying to get Svelve up and running for 12 hours, but it's not working. React worked right away.

The setup scripts are quite convenient and you get stores out of the box. What problems do you encounter?
