Release Notes

bufbuild/protobuf-es (@​bufbuild/protobuf)

v2.14.1

Compare Source

What's Changed

This release deprecates configureTextEncoding() from @bufbuild/protobuf/wire. If you run @bufbuild/protobuf in an environment that does not provide the Text Encoding API, please migrate to a polyfill that installs TextEncoder (with the methods encode and optionally encodeInto) and TextDecoder (with the fatal: true constructor argument and the decode method) on globalThis instead. Please see #​1517 for the rationale.

• Apply import_extension only to relative import paths by @​timostamm in #​1515
• Stop sharing the text encoding implementation via globalThis by @​timostamm in #​1517

What's new in version 2

To support Protobuf editions, we have to make breaking changes that also affect users of proto2 and proto3. This prompted us to make more extensive changes that take feedback from version 1 into account:

We no longer use classes. Instead, we generate a schema object and a type for every message. To create a new instance, to serialize, and for other concerns, we provide functions. Here is a simple example:

import { create, toBinary } from "@bufbuild/protobuf";
import { UserSchema } from "./gen/example_pb";

let user = create(UserSchema, {
  firstName: "Homer",
  lastName: "Simpson",
  active: true,
});

const bytes = toBinary(UserSchema, user);

If you use proto3, messages are now plain objects. Files with proto2 and editions use the prototype chain to track field presence.

This approach solves several outstanding issues, such as:

• #​397 Provide custom options at runtime
• #​551 Generated types allow assigning wrong message type if it is a superset of the target type
• #​414 Improvements for proto2 required
• #​738 type-save full enum value names
• #​928 Better interop with 3rd party frameworks requiring plain objects
• #​508 JSON types

[!TIP]

Take a look at the upgrade guide to learn more.

[!NOTE]

Connect-ES does not support version 2 yet. We will update it shortly.

🔴 Protobuf runtime upgraded to v2 but generated code still uses incompatible v1 API, breaking all proto operations

The protobuf runtime dependency is upgraded to v2 ("@bufbuild/protobuf": "^2.0.0" at livekit-ffi-node-bindings/package.json:36) without regenerating the proto files, so all protobuf serialization and deserialization will fail at runtime.

Impact: The package is completely non-functional — any code that imports or uses protobuf messages will crash.

Generated proto files use v1 APIs that don't exist in v2

The proto files in proto/ were generated by protoc-gen-es v1.10.1 (visible in the header comment of each file, e.g. proto/audio_frame_pb.js:15). They import and use v1-specific APIs:

• const { proto2 } = require("@bufbuild/protobuf") — proto/audio_frame_pb.js:23
• proto2.makeEnum(...) — used extensively across all proto JS files
• proto2.makeMessageType(...) — used extensively across all proto JS files
• import { Message, proto2 } from "@bufbuild/protobuf" — proto/audio_frame_pb.d.ts:21
• import type { BinaryReadOptions, FieldList, JsonReadOptions, JsonValue, PartialMessage, PlainMessage } from "@bufbuild/protobuf" — proto/audio_frame_pb.d.ts:20

In @bufbuild/protobuf v2, the Message base class, proto2.makeEnum, proto2.makeMessageType, and the type exports like FieldList and PlainMessage were all removed or completely restructured. The v2 library uses a descriptor-based approach instead.

Additionally, devDependencies still pins @bufbuild/protoc-gen-es at ^1.10.1 which has a peer dependency on @bufbuild/protobuf@1.10.1, creating a version conflict (pnpm-lock.yaml shows it resolved with @bufbuild/protobuf@2.12.1 which is incompatible).

The index.d.ts:31 also re-exports PartialMessage from @bufbuild/protobuf, which has a different type signature in v2.

Prompt for agents

The @bufbuild/protobuf runtime was upgraded from v1 to v2, but the generated proto files in proto/ were generated with protoc-gen-es v1.10.1 and use the v1 API (Message class, proto2.makeEnum, proto2.makeMessageType, etc.) which does not exist in v2. There are two approaches to fix this:

1. Keep @bufbuild/protobuf at v1: Revert the dependency back to "^1.10.1" to match the generated code.

2. Fully migrate to v2: Upgrade @bufbuild/protoc-gen-es to v2 in devDependencies, then regenerate all proto files using the v2 plugin (which produces completely different output using the descriptor-based API). Also update index.d.ts since PartialMessage has moved in v2.

The devDependency @bufbuild/protoc-gen-es should always match the major version of the @bufbuild/protobuf runtime dependency.

🟡 Missing changeset file required by repository contribution rules

No changeset file was added for this PR (no new files in .changeset/ directory at livekit-ffi-node-bindings/package.json:36), so the change cannot be properly documented or versioned.

Impact: The dependency bump won't be tracked in the changelog and may not trigger the required version bump.

AGENTS.md requires a changeset for every PR

The AGENTS.md file states:

• "Every PR needs a changeset"
• "Changeset must list any crates which need to be bumped stemming from the change"
• "Document changes interactively from the CLI with knope document-change or create manually in /.changeset"

The git diff between the base and head commits shows no new files in .changeset/. Since this PR changes a runtime dependency version (which is a breaking change), it especially needs a changeset documenting the bump.

Prompt for agents

Add a changeset file in /.changeset/ documenting this dependency upgrade. You can create one interactively with `knope document-change` or manually create a markdown file in the .changeset directory that lists the @livekit/rtc-ffi-bindings package as needing a version bump due to the @bufbuild/protobuf upgrade.
