Patch Changes

• #197 0409821 Thanks @teamchong! - Treat Workers fetch and connect lifecycle methods as passthrough methods on WorkerEntrypoint and DurableObject targets.

Patch Changes

• #194 4093556 Thanks @teamchong! - Fix @validateRpc() breaking decorated classes that extend other decorated classes: prototype methods are now wrapped in place instead of returning a Proxy from the constructor, so subclass-only methods validate correctly, instances stay real branded RpcTargets, and incoming callback stubs pass through as native stubs (opt in to validating them with validateStub<T>(stub)).

Minor Changes

• #169 2cb51eb Thanks @teamchong! - Introduced capnweb-validate, a separate package that allows you to wrap your RPC interfaces in runtime type-checking based on your TypeScript interfaces.

Minor Changes

• #155 48f4d49 Thanks @G4brym! - Add Blob as a serializable type over RPC. Blob objects can now be passed as call arguments and return values. The MIME type (blob.type) is preserved across the wire.

Patch Changes

• #166 7413e43 Thanks @aron-cf! - Errors properties, using Object.keys(), are now preserved across the wire. Attach fields like code or details to an Error and they propagate to the other side. The cause and errors (for AggregateError) properties will also be preserved.

• #168 25baebf Thanks @kentonv! - Fix memory leak that kept all messages received in a session pinned in memory until the session ended, due to surprising implementation details of JavaScript Promises.

• #152 9e499e2 Thanks @VastBlast! - Fix serialization for Invalid/NaN dates

Minor Changes

• #159 7cb9132 Thanks @aron-cf! - Added support for Bun's alternative WebSocket server API.

Patch Changes

• #148 189fa79 Thanks @kentonv! - Fixed type overrides for Uint8Array's toBase64 and fromBase64 leaking into capnweb's public interface.

Minor Changes

• #145 5667226 Thanks @kentonv! - When Node's Buffer is available, Cap'n Web will now serialize it the same as Uint8Array, and will deserialize all byte arrays as Buffer by default. Buffer is a subclass of Uint8Array, so this should be compatible while being convenient in Node apps.

• #142 60be60d Thanks @VastBlast! - Major improvements to type definitions, fixing bugs and making them more accurate.

Patch Changes

• #145 5667226 Thanks @kentonv! - Fixed base64 encoding of very large byte arrays on platforms that don't support Uint8Array.toBase64().

Minor Changes

• #132 c2bb17b Thanks @kentonv! - Added support for sending ReadableStream and WritableStream over RPC, with automatic flow control.

Patch Changes

• #129 10abaf3 Thanks @dmmulroy! - Fix RpcCompatible type to filter out symbol keys instead of mapping them to never

Minor Changes

• #121 32e362f Thanks @kentonv! - Improved compatibility with Cloudflare Workers' built-in RPC, particularly when proxying from one to the other.

Minor Changes

• #78 8a47045 Thanks @itaylor! - The package now exports the type RpcCompatible<T> (previously called Serializable<T>, but not exported), which is needed when writing generic functions on RpcStub / RpcPromise.

Patch Changes

• #120 1c87560 Thanks @kentonv! - Fixed serialization of async functions.

• #117 d21e4ca Thanks @codehz! - Enhance Stubify and Unstubify for tuple types
