Sorry, something went wrong.
By default, TypeScript interfaces like `DataView` and `Uint8Array` are used with the more generic `ArrayBufferLike` type, representing that they can work with either `ArrayBuffer` or `SharedArrayBuffer`. TypeScript 5.9 now uses stricter types for interfaces such as the DOM `fetch` method: a DOM `BufferSource` is now (correctly) marked as requiring `ArrayBuffer`, not `SharedArrayBuffer`. As a result of that change, trying to use a @msgpack/msgpack `encode` result with a `fetch` call will result in a type error. This change updates the types in the `Encoder` class to use `ArrayBuffer` instead of `ArrayBufferLike`, which reflects their implementation and prevents issues with the newer, stricter interfaces.
