- Replit AI in chat: open the chat panel and ask the AI to explain an error or rewrite a function.
- Secrets manager: store credentials as environment variables instead of pasting them into your code.
Replit Common Mistakes to Avoid
Mistake #1: Hardcoding secrets
❌ 間違い: Pasting API keys straight into your code where anyone can see them.
✅ 右: Store every key in the Secrets tab as environment variables.
Mistake #2: Vague AI prompts
❌ 間違い: Asking the agent to “build an app” with no detail.
✅ 右: Write a clear prompt, like a web app showing an interactive map.
Mistake #3: Skipping version control
❌ 間違い: Editing big projects with no backup of older versions.
✅ 右: GitHubに接続 早い so you can fix issues by rolling back.
Replit Troubleshooting
Problem: App is unreachable
原因： Network issues like ISP blocking or a router firewall rule.
修理： Try a different network, then re-open the link in your browser.
Problem: Packages won’t install
原因： A typo in the package name or a missing requirements file.

📌 注記： If none of these fix your issue, contact Replit support.
