  • wrangler dev listens on IPv4 by default - EverlastingBugstopper, issue/1198 pull/1405

    Before, wrangler dev would listen on [::1]:8787 by default, and call it localhost in the terminal output. This was confusing for developers whose localhost resolves to IPv4 and not IPv6. Now, wrangler dev will listen on 127.0.0.1:8787 by default. This can be overriden by passing values via the --ip and --port flags.

  • Clarify where to find your account_id in the dashboard - EverlastingBugstopper, issue/1364 pull/1395

    When you create a new project with wrangler generate, it directs you to the Cloudflare Dashboard to find your account_id and zone_id. However, this flow only worked if you had your own domain. Developers who only use workers.dev for their Workers were directed to a page that does not exist! This message now points everyone to a page where they can find the information that they need.

• Fixes

  • Allow creation of preview namespaces when a namespace already exists in wrangler.toml - EverlastingBugstopper, pull/1414

    When we introduced KV preview namespaces, we made sure to add nice messages when creating new namespaces so people could easily add the new namespace id to their wrangler.toml in the correct place.

    However, we missed a very common case where developers already have a production namespace defined in their wrangler.toml and they want to add a preview namespace. When this is the case, we returned an error message intended to only be thrown when running either wrangler preview or wrangler dev. This is now fixed!

  • Allow multiple response header values in wrangler dev - EverlastingBugstopper, issue/1412 pull/1413

    Before, wrangler dev would not properly handle response headers that have multiple values. We would iterate over all response headers coming from the Workers runtime, and "insert" them into the header map instead of appending them. This is no longer the case and response headers should now work as expected. More details on this issue can be found here.

  • Fix kv-namespace/kv_namespace behavior in environments - EverlastingBugstopper, issue/1408 pull/1409

    When KV namespace support was initially added to Wrangler, we documented using kv-namespaces in wrangler.toml. Unfortunately, the - was not consistent with other fields such as zone_id and account_id, so the decision was made to allow both kv-namespaces and kv_namespaces. When this change was introduced, it worked with top level kv_namespaces entries, but not in environments. This is now fixed! You can now use kv_namespaces everywhere you can use kv-namespaces.

• Maintenance

  • Add link to testing docs in CONTRIBUTING.md - luanraithz, pull/1416

  • Remove unused Krate::install code - EverlastingBugstopper, [issue/247] pull/1410

    When we introduced our own version checking for Wrangler we stopped using Krate::install. This PR just removes that unused code.
