Frequently asked questions
How do I ensure my Wrangler configuration is valid?
Use the schema provided in the wrangler.jsonc file at ./node_modules/wrangler/config-schema.json.
Can I use local storage for development?
Yes, Wrangler defaults to local storage simulation during development unless remote bindings are explicitly configured.
How do I handle secrets securely?
Use the interactive wrangler secret put command. Never hardcode secrets in commands or commit them to version control.
Does Workers AI run locally?
No, Workers AI always runs remotely and incurs usage charges.
