# Wrangler & Cloudflare surface cheatsheet > Unofficial, agentstack-authored. Not affiliated with or endorsed by Cloudflare. Use this skill to pick the right `wrangler` command for a Cloudflare task without guessing. Commands assume Wrangler v3+; run `wrangler --version` if unsure. ## Workers - Develop locally: `wrangler dev` (add `--remote` to run against the edge). - Deploy: `wrangler deploy` (scope with `--env <name>`). - Validate a build only: `wrangler deploy --dry-run --outdir dist`. - Live logs: `wrangler tail`. - Roll back: `wrangler deployments list`, then `wrangler rollback <id>`. ## Secrets & vars - Set a secret: `wrangler secret put <NAME>` (value entered interactively). - List secrets: `wrangler secret list`. Delete: `wrangler secret delete <NAME>`. - Plaintext config vars live in `[vars]` in `wrangler.toml` — never secrets. ## KV (key-value) - Create namespace: `wrangler kv namespace create <BINDING>`. - Write/read: `wrangler kv key put <KEY> <VALUE> --binding <BINDING>` / `wrangler kv key get <KEY> --binding <BINDING>`. ## R2 (object storage) - Create bucket: `wrangler r2 bucket create <NAME>`. - Upload/download: `wrangler r2 object put <BUCKET>/<KEY> --file <PATH>` / `wrangler r2 object get <BUCKET>/<KEY>`. ## D1 (SQL) - Create db: `wrangler d1 create <NAME>`. - Run SQL: `wrangler d1 execute <NAME> --command "SELECT 1"` or `--file ./schema.sql`. Use `--local` for the local dev database. ## Pages - Deploy a build output dir: `wrangler pages
