Minor Changes

• #13726 b5ac54b Thanks @penalosa! - Hard fail on Node.js < 22

  Wrangler no longer supports Node.js 20.x, as it reached end-of-life on 2026-04-30. The minimum supported Node.js version is now 22.0.0. See https://github.com/nodejs/release?tab=readme-ov-file#end-of-life-releases.

• #13717 9a1f014 Thanks @NuroDev! - Add an experimental experimental_generateTypes() programmatic API.

  Wrangler now exposes experimental_generateTypes() from the package root so you can generate Worker types in code using the same logic as wrangler types. The API supports the same core type-generation options (include env/runtime toggles) and returns structured output with separate env and runtime content alongside the combined formatted output.

• #13711 1c4d850 Thanks @dario-piotrowicz! - fix: skip auto-config and OpenNext delegation when --config is explicitly provided

  When --config is passed to wrangler deploy, the user is explicitly targeting a specific Worker configuration. Previously, wrangler would ignore --config and delegate to opennextjs-cloudflare deploy if it detected an OpenNext project in the working directory, silently deploying the wrong Worker. Now, both auto-config detection and OpenNext delegation are skipped when --config is provided, matching the existing behavior for --script and --assets.

• #13735 6d28037 Thanks @edmundhung! - Improve config-schema.json hover text in more editors

  Wrangler now emits markdownDescription in config-schema.json alongside the existing description field. Editors that support rich JSON Schema hovers can use that markdown directly instead of rendering escaped links and formatting.

• #13722 0827815 Thanks @MattieTK! - Improve safe telemetry categorisation for user-facing Wrangler errors.

• #13116 e539008 Thanks @dario-piotrowicz! - Allow getPlatformProxy and unstable_getMiniflareWorkerOptions to start when the assets directory does not exist yet

  Previously, getPlatformProxy would catch and swallow NonExistentAssetsDirError internally when the configured assets directory was absent on disk. This has been refactored so that the directory-existence check is skipped entirely for getPlatformProxy and unstable_getMiniflareWorkerOptions, since these APIs are typically used at dev time in frameworks where the assets directory is a build output that may not exist yet.

  wrangler dev, wrangler deploy, wrangler versions upload, and wrangler triggers deploy continue to require the assets directory to exist when specified.
