Frequently Asked Questions
Should I use wrangler.jsonc or wrangler.toml?
Both are supported; Cloudflare's newer docs favor wrangler.jsonc, which allows comments and has a JSON schema for editor validation.
What is compatibility_date?
It pins the Workers runtime behavior to a date so updates don't break your code unexpectedly. Use a recent date for new projects.
Where do binding IDs come from?
Create resources with wrangler (for example "wrangler kv namespace create") and paste the returned IDs over the placeholders.
Do I need nodejs_compat?
Only if your code or dependencies use Node.js built-in modules such as node:buffer or node:crypto.
