This is independent of `enabled`. It can stay true while caching is off, so the preference survives turning caching off and back on. - `compatibility_date?: string` Date indicating targeted support in the Workers runtime. Backwards incompatible fixes to the runtime following this date will not affect this Worker. - `compatibility_flags?: Array` Flags that enable or disable certain features in the Workers runtime.

When set, the namespace is container-enabled. Valid only on live entries. - `state?: "created"` Live export. May be omitted; defaults to `created`. - `"created"` - `WorkersDurableObjectDeletedExport` A `deleted` tombstone: retires the provisioned namespace for this class and all of its data. The class must be absent from the uploaded code and no other Worker in the account may bind to the namespace, otherwise the deploy is rejected. No other fields are allowed. Deletion is irreversible. - `state: "deleted"` Tombstone that deletes the namespace. - `"deleted"` - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectRenamedExport` A `renamed` tombstone: rewrites the provisioned namespace's class name from this map key to `renamed_to`. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `transferred_to` and `transfer_from` are not allowed. - `renamed_to: string` The destination class name. Must differ from the source class (the map key) and must be declared as a live (`created`) entry in the same `exports` map. Write-only: never present in GET responses. - `state: "renamed"` Tombstone that renames the namespace's class. - `"renamed"` - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectTransferredExport` A `transferred` tombstone (source side of a two-phase transfer): hands ownership of the provisioned namespace to another script in the same account, named by `transferred_to`. The target must have already deployed a matching `expecting-transfer` entry. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `renamed_to` and `transfer_from` are not allowed. - `state: "transferred"` Tombstone that transfers the namespace to another script. - `"transferred"` - `transferred_to: string` The destination script name. Must be in the same account and the same dispatch-namespace context (or both non-dispatch). Cross-dispatch-namespace transfers are rejected. Write-only: never present in GET responses. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectExpectingTransferExport` The target side of a two-phase transfer (`state: expecting-transfer`). Declares that this script expects to receive a namespace for this class from the `transfer_from` script. This is a live entry, not a tombstone: bindings resolve through the source's namespace until the source commits with a `transferred` tombstone. `storage` and `transfer_from` are required; `renamed_to` and `transferred_to` are not allowed. - `state: "expecting-transfer"` Target side of a two-phase transfer. - `"expecting-transfer"` - `storage: "sqlite" | "legacy-kv"` Durable Object storage backend. `sqlite` is the recommended (and only) backend for new namespaces. `legacy-kv` is accepted only for a class whose namespace already exists as KV-backed; the `exports` flow never provisions a new `legacy-kv` namespace. - `"sqlite"` - `"legacy-kv"` - `transfer_from: string` The source script name to receive the namespace from. Must be in the same account and dispatch-namespace context. Present on reads for `expecting-transfer` entries. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `container?: string` Name of the container (declared in the upload's `metadata.containers`) that backs this Durable Object once the transfer settles. Valid only on live entries. - `keep_bindings?: Array` List of binding types to keep from previous_upload. - `package_dependencies?: Array` The list of npm packages that were installed and used when this Worker version was built. - `installedVersion: string` The exact version that was resolved and installed by the package manager. - `name: string` The npm package name. - `packageJsonVersion: string` The version constraint as written in package.json. - `usage_model?: "standard" | "bundled" | "unbound"` Usage model for the Worker invocations. - `"standard"` - `"bundled"` - `"unbound"` - `bindings_inherit?: "strict"` Query param: When set to "strict", the upload will fail if any `inherit` type bindings cannot be resolved against the previous version of the Worker. Without this, unresolvable inherit bindings are silently dropped. - `"strict"` - `files?: Array` Body param: An array of modules (often JavaScript files) comprising a Worker script. At least one module must be present and referenced in the metadata as `main_module` or `body_part` by filename.

Required if `format` is "jwk". - `WorkersBindingKindWorkflow` - `name: string` A JavaScript variable name for the binding. - `type: "workflow"` The kind of resource that the binding provides. - `"workflow"` - `workflow_name: string` Name of the Workflow to bind to. - `class_name?: string` Class name of the Workflow. Should only be provided if the Workflow belongs to this script. - `script_name?: string` Script name that contains the Workflow. If not provided, defaults to this script name. - `WorkersBindingKindWasmModule` - `name: string` A JavaScript variable name for the binding. - `part: string` The name of the file containing the WebAssembly module content. Only accepted for `service worker syntax` Workers. - `type: "wasm_module"` The kind of resource that the binding provides. - `"wasm_module"` - `WorkersBindingKindVPCService` - `name: string` A JavaScript variable name for the binding. - `service_id: string` Identifier of the VPC service to bind to. - `type: "vpc_service"` The kind of resource that the binding provides. - `"vpc_service"` - `WorkersBindingKindVPCNetwork` - `name: string` A JavaScript variable name for the binding. - `type: "vpc_network"` The kind of resource that the binding provides. - `"vpc_network"` - `network_id?: string` Identifier of the network to bind to.

Mutually exclusive with network_id. - `script?: Script` - `etag?: string` Hashed script content - `handlers?: Array` The names of handlers exported as part of the default export. - `last_deployed_from?: string` The client most recently used to deploy this Worker. - `named_handlers?: Array` Named exports, such as Durable Object class implementations and named entrypoints. - `handlers?: Array` The names of handlers exported as part of the named export. - `name?: string` The name of the exported class or entrypoint. - `script_runtime?: ScriptRuntime` Runtime configuration for the Worker. - `compatibility_date?: string` Date indicating targeted support in the Workers runtime. Backwards incompatible fixes to the runtime following this date will not affect this Worker. - `compatibility_flags?: Array` Flags that enable or disable certain features in the Workers runtime. - `exports?: Record` Declarative exports for this version, including Durable Object classes (with their `storage` backend) and named Worker entrypoints. Tombstoned lifecycle entries are omitted, so only live exports (`created` and `expecting-transfer`) are returned. - `WorkersWorkerExport` A named Worker entrypoint export (`type: worker`). Worker entrypoints are always live (`state: created`) and carry no storage or lifecycle fields. The optional `cache` block overrides the Worker's global `cache_options.enabled` for this entrypoint. - `type: "worker"` Marks this entry as a Worker entrypoint export. - `"worker"` - `cache?: Cache` Cache override for this entrypoint. Overrides the Worker's global `cache_options.enabled` for this entrypoint only. - `enabled: boolean` Whether caching is enabled for this entrypoint. - `state?: "created"` Live export. May be omitted; defaults to `created`. - `"created"` - `WorkersDurableObjectExport` A live Durable Object export (`state: created`, the default). The platform auto-provisions the namespace on first deploy, matches it on subsequent deploys, and never mutates or deletes it as a side effect of a code-only change. `storage` is required; `renamed_to`, `transferred_to` and `transfer_from` are not allowed on a live entry. - `storage: "sqlite" | "legacy-kv"` Durable Object storage backend. `sqlite` is the recommended (and only) backend for new namespaces. `legacy-kv` is accepted only for a class whose namespace already exists as KV-backed; the `exports` flow never provisions a new `legacy-kv` namespace. - `"sqlite"` - `"legacy-kv"` - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `container?: string` Name of the container (declared in the upload's `metadata.containers`) that backs this Durable Object. When set, the namespace is container-enabled. Valid only on live entries. - `state?: "created"` Live export. May be omitted; defaults to `created`. - `"created"` - `WorkersDurableObjectDeletedExport` A `deleted` tombstone: retires the provisioned namespace for this class and all of its data. The class must be absent from the uploaded code and no other Worker in the account may bind to the namespace, otherwise the deploy is rejected. No other fields are allowed. Deletion is irreversible. - `state: "deleted"` Tombstone that deletes the namespace. - `"deleted"` - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectRenamedExport` A `renamed` tombstone: rewrites the provisioned namespace's class name from this map key to `renamed_to`. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `transferred_to` and `transfer_from` are not allowed. - `renamed_to: string` The destination class name. Must differ from the source class (the map key) and must be declared as a live (`created`) entry in the same `exports` map. Write-only: never present in GET responses. - `state: "renamed"` Tombstone that renames the namespace's class. - `"renamed"` - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectTransferredExport` A `transferred` tombstone (source side of a two-phase transfer): hands ownership of the provisioned namespace to another script in the same account, named by `transferred_to`. The target must have already deployed a matching `expecting-transfer` entry. The source class may stay in code during the rollout window (an info notice is emitted). `storage`, `renamed_to` and `transfer_from` are not allowed. - `state: "transferred"` Tombstone that transfers the namespace to another script. - `"transferred"` - `transferred_to: string` The destination script name. Must be in the same account and the same dispatch-namespace context (or both non-dispatch). Cross-dispatch-namespace transfers are rejected. Write-only: never present in GET responses. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `WorkersDurableObjectExpectingTransferExport` The target side of a two-phase transfer (`state: expecting-transfer`). Declares that this script expects to receive a namespace for this class from the `transfer_from` script. This is a live entry, not a tombstone: bindings resolve through the source's namespace until the source commits with a `transferred` tombstone. `storage` and `transfer_from` are required; `renamed_to` and `transferred_to` are not allowed. - `state: "expecting-transfer"` Target side of a two-phase transfer. - `"expecting-transfer"` - `storage: "sqlite" | "legacy-kv"` Durable Object storage backend. `sqlite` is the recommended (and only) backend for new namespaces. `legacy-kv` is accepted only for a class whose namespace already exists as KV-backed; the `exports` flow never provisions a new `legacy-kv` namespace. - `"sqlite"` - `"legacy-kv"` - `transfer_from: string` The source script name to receive the namespace from. Must be in the same account and dispatch-namespace context. Present on reads for `expecting-transfer` entries. - `type: "durable-object"` Marks this entry as a Durable Object export. - `"durable-object"` - `container?: string` Name of the container (declared in the upload's `metadata.containers`) that backs this Durable Object once the transfer settles. Valid only on live entries. - `limits?: Limits` Resource limits for the Worker. - `cpu_ms?: number` The amount of CPU time this Worker can use in milliseconds. - `migration_tag?: string` The tag of the Durable Object migration that was most recently applied for this Worker. - `usage_model?: "bundled" | "unbound" | "standard"` Usage model for the Worker invocations. - `"bundled"` - `"unbound"` - `"standard"` - `id?: string` Unique identifier for the version. - `exports_reconciliation?: ExportsReconciliation` Summary of the declarative exports reconciliation that ran on this upload. Populated only when the uploaded metadata included an `exports` block. Durable Object entries drive reconciliation; `type: worker` entries do not contribute to this summary. - `created: Array` Class names for which a new namespace was provisioned. - `deleted: Array` Class names whose namespace was deleted by a `deleted` tombstone. - `info: Array` Non-blocking info entries (stale tombstones, tombstone applied with class still in code). See `exports_reconciliation_info`. - `class: string` The class name the info entry is about. - `message: string` Human-readable explanation. - `scenario: "code_class_not_in_exports" | "provisioned_class_missing_from_config" | "config_export_not_in_code" | 30 more` Stable, machine-readable tag identifying which reconciliation scenario produced an error, warning, or info entry.
