Wrangler & the dev loop

Lesson 2 of 5

wrangler config declares what your Worker needs, wrangler dev runs it locally, and everything the platform gives you arrives through one door — the env bindings object.

  • Run the local dev loop and split config across environments
  • Keep plain config in vars and credentials in secrets — and receive both through env
