wrangler@4.136.0

Summary

Minor Changes #15713 3c75cad Thanks @jamesopstad ! - Identify experimental Build Output resource configs by filename and location The root remains config.json , Worker configs are now worker.config.json , and Container configs are now container.config.json . Resource configs no longer contain top-level type discriminators, while settings and build context are stored together in the root config. #15713 3c75cad Thanks @jamesopstad ! - Define experimental Cloudflare configuration with a single default export Experimental cloudflare.config.ts files now define settings and resources together in a default-exported defineConfig() call. Add a Worker under worker , add Containers to the containers array, or omit both to provide settings only. import * as entrypoint from "./src/index.ts" with { type : "cf-worker" } ; export default defineConfig ( { accountId : "..." , complianceRegion : "public" , worker : { name : "my-worker" , compatibilityDate : "2026-09-18" , entrypoint , } , } ) ; #15720 35668d7 Thanks @alexkli ! - Add experimental --zone and --zone-id flags to wrangler deploy and wrangler triggers deploy to attach a zone to routes passed via --route Routes passed on the command line were always sent to the Cloudflare API as bare patterns. Zones with an SSL for SaaS entitlement reject such routes with error 10082 ("When using wildcard host ssl for saas entitlement you must specify the zone per route using zone_id or zone_name"), and until now the only way to set a zone was in the config file, which --route overrides. The new flags are experimental and must be enabled with --experimental-route-zones (alias --x-route-zones ). Pass a single zone to apply it to all routes, or one zone per route in the same order as the --route flags: wrangler deploy --x-route-zones --route "app.example.com/*" --route "api.example.com/*" --zone example.com wrangler deploy --x-route-zones --route "a.example.com/*" --zone example.com --route "b.example.net/*" --zone example.net --zone sets zone_name and --zone-id sets zone_id on each route. The two flags cannot be combined, and passing more than one zone requires exactly one per --route . Routes without zone flags behave exactly as before. #15699 45b3b81 Thanks @skepticfx ! - Remove the experimental Container image environment binding Durable Object-managed Containers now use ctx.container.images without Wrangler generating env.EXPERIMENTAL_CLOUDFLARE_CONTAINER_IMAGES . Update code using the experimental environment binding to read ctx.container.images and regenerate your Worker types. Version deployments identify managed applications from native named images, and --containers-rollout=none preserves native Container metadata. Containers without named images must first be provisioned with wrangler deploy ; versions upload verifies that their applications already exist. The old binding is no longer read or reserved, including on previously uploaded versions. keep_vars retains existing variables as usual; redeploy without it to remove an existing experimental binding. #15702 8235e6a Thanks @podonnell-dev ! - Return structured configuration errors from wrangler preview --json When a Worker is missing its Preview configuration, JSON mode now returns an error , a suggested_config patch, and any associated onboarding messages without interactive output or terminal formatting. This changes the private-beta Preview command to make automated onboarding reliable. #15577 731a2ee Thanks @sdnts ! - Add support for jurisdictions to Queues subcommands Patch Changes #15711 91e2f86 Thanks @ghostwriternr ! - Allow local Container images without exposed ports Wrangler and the Cloudflare Vite plugin no longer reject images that omit Docker EXPOSE metadata. Local Containers can run command-only workloads or serve traffic through workerd without declaring an unused image port. #15740 c5913a6 Thanks @dependabot ! - Update dependencies of "miniflare", "wrangler" The following dependency versions have been updated: Dependency From To @cloudflare/workers-types ^5.20260918.1 ^5.20260921.1 workerd 1.20260918.1 1.20260921.1 #15471 0751490 Thanks @edmundhung ! - Fix cf builds for static projects that serve assets from the project root The experimental Build Output path now omits the reserved .cloudflare directory when the project root is used for static assets. This prevents recursive output copying in Wrangler while preserving the existing behaviour for other asset directories. #15440 43b1f85 Thanks @HuzaifaAbdulRehman ! - Rebase absolute non-JavaScript module specifiers when preserve_file_names is enabled With preserve_file_names set, a non-JS module imported by an absolute path kept that path as its module name. The build machine's filesystem layout ended up inside the deployed Worker, and the module was never written to --outdir . A local dry run reported success while the upload failed server-side with error code 10021 . Tooling that rewrites externals to absolute paths hits this, which is how it was found in @opennextjs/cloudflare with WASM imports. Absolute specifiers are now rebased to ./<basename> , which is what the hashed branch of the same code already does minus the hash prefix. Relative specifiers keep the behaviour they had.
