Using "wrangler". How do I deploy my Worker?
Expected outcome:
- Run these commands:
- 1. wrangler deploy - Deploy to production
- 2. wrangler deploy --env staging - Deploy to staging environment
- 3. wrangler deploy --dry-run - Validate without deploying
- Make sure to run wrangler check first to validate your config.
Using "wrangler". How do I add a KV namespace?
Expected outcome:
- 1. Create namespace: wrangler kv namespace create MY_KV
- 2. Add to wrangler.jsonc:
- { "kv_namespaces": [{ "binding": "KV", "id": "<ID>" }] }
- 3. Run wrangler types to update TypeScript bindings
Security Audit
Safev1 • 2/17/2026
All 161 static findings are false positives. The skill is official Cloudflare documentation for the Wrangler CLI tool. External command detections are legitimate CLI commands documented in code blocks. Network detections are official Cloudflare URLs and localhost testing endpoints. Environment variable access is standard secret management documentation. No malicious behavior detected.

Try These Prompts
Basic Worker deployment
How do I deploy my Worker to Cloudflare using wrangler?
Configure KV namespace
Show me how to add a KV namespace binding to my wrangler.jsonc config
Set up secrets
How do I securely add API keys as secrets for my Worker?
Local development with bindings
How do I test my Worker locally with remote R2 and AI bindings?
Best Practices
- Run wrangler check before every deployment to catch configuration errors
- Use wrangler types after any config changes to regenerate TypeScript bindings
- Set compatibility_date to a recent date within 30 days for latest features
Avoid
- Hardcoding secrets directly in wrangler.jsonc - use wrangler secret instead
- Skipping wrangler types after adding new bindings
- Deploying without testing locally first using wrangler dev
Frequently Asked Questions
What version of wrangler should I use?
Use wrangler v4.x or later. Check with wrangler --version.
Can I use TOML or JSON for config?
Prefer wrangler.jsonc (JSON with comments). Newer features are JSON-only.
How do I test my Worker locally?
Run wrangler dev. Use wrangler dev --remote for Cloudflare bindings.
Where should I store local development secrets?
Use .dev.vars file in your project root. Never commit this file.
How do I rollback a bad deployment?
Use wrangler rollback or wrangler rollback <VERSION_ID>.
Does Workers AI work locally?
No, Workers AI always runs remotely and incurs charges even in local dev.
