JSON serialization options

[nicole0707]

From the docs https://github.com/bufbuild/protobuf-es/blob/main/docs/runtime_api.md#json-serialization-options, Message.fromJson is supposed to allow some option like enumAsInteger.

However, JsonReadOptions seems to include different options from code https://github.com/bufbuild/protobuf-es/blob/main/packages/protobuf/src/json-format.ts#L86.

Just wondering if the doc is out of date, is there any recommended way to support these options with fromJSON ?

Cheers.

Hey Nicole, when parsing an enum value from JSON, the full enum value name or the integer value are both accepted.

So for the Protobuf enum Foo { FOO_BAR=1 }, both JSON values "FOO_BAR" and 1 parse the same.

There isn't a JsonReadOption for it because both forms must be accepted to interop with other Protobuf implementations. If you serialize to JSON, you need to make a choice, so it is available as a JsonWriteOption.

Oops, @smaye81 just pointed out I'm, wrong. Yes, the docs for "JSON serialization options" are swapped. Thanks for letting us know, @nicole0707.
