This PR updates the repository from TypeScript 5.6 to 5.9.
Important
TypeScript 5.9 includes breaking changes to lib.d.ts, forcing us to change return types for some functions from
Uint8ArraytoUint8Array<ArrayBuffer>.A similar change was made in Protobuf-ES v2.7.0, and with this PR,
@connectrpc/connectand related packages depend on@bufbuild/protobufv2.7.0 or later.If you are on TypeScript 5.7 or later, you will not see any issues, because it already ships with the new type parameter.
If you are on TypeScript 5.6 and earlier, you may be affected by this change. If you use
Compression,Serialization,UniversalClientFn,UniversalHandlerFnorencodeEnvelopefrom@connectrpc/connect/protocol, the new typeUint8Array<ArrayBuffer>will becomeany, because the compiler does not understand the type.If you are just using Connect clients or servers, you should not see any issues.
