[!IMPORTANT]

TypeScript 5.9 includes breaking changes to lib.d.ts, forcing us to change return types for some functions from Uint8Array to Uint8Array<ArrayBuffer>. This is unlikely to affect you, but if it does, see #​1560 for details.

• Update to TypeScript 5.9 and change return types from Uint8Array to Uint8Array<ArrayBuffer> by @​timostamm in #​1560
• Drop support for Node.js 18 by @​timostamm in #​1559

What's Changed

The only noteworthy changes in this release are enhancements made to the @​connectrpc/connect-migrate package.

The migration tool now handles additional scenarios for migrating your code to Connect v2:

Transforms new to create:

- import { Foo } from "./foo_pb.js";
+ import { FooSchema } from "./foo_pb.js";
+ import { create } from "@​bufbuild/protobuf";
- const foo = new Foo();
+ const foo = create(FooSchema);

Transforms isMessage to use the schema:

import { isMessage } from "@​bufbuild/protobuf";
- import { Foo } from "./foo_pb.js";
+ import { FooSchema } from "./foo_pb.js";
- isMessage(1, Foo); 
+ isMessage(1, FooSchema);

Transforms the static fromBinary, fromJson, and fromJsonString method calls:

- import { Foo } from "./foo_pb.js";
+ import { FooSchema } from "./foo_pb.js";
+ import { fromJson } from "@​bufbuild/protobuf";
- Foo.fromJson(x, y);
+ fromJson(FooSchema, x, y);

In addition, if the message is a well-known type, the import path is updated accordingly.

For details on Connect v2, see the v2 release notes as well as the full migration guide.

• Transform class references in connect-migrate by @​timostamm and @​smaye81 in #​1342

What's Changed

• We're upgrading to Protobuf-ES version 2. It's the largest change in this release.
• Connect-ES no longer needs its own code generator plugin.
• We're adding support for Next.js 15, Fastify 5, and Express 5.
• We're dropping support for old versions of Node.js and TypeScript. You'll need at least Node.js 18.14.1 and TypeScript 4.9.6.

The upgrade of the Protobuf runtime brings support for Editions and new APIs for Protobuf messages with support for custom options. Messages are now plain TypeScript types, which greatly improves compatibility with the ecosystem. For example, messages can be passed from a server-side component in Next.js to a client-side component without losing any data or types. To learn more about the enhancements, see the release blog post for Protobuf-ES v2.

[!TIP]
If you are already using Connect, see our migration guide to upgrade to version 2.
