How to get protobuf.js to output enum strings instead of integers
The generated JS code from protoc has a map in one direction only e.g.
proto.foo.Bar.Myenum = { HEY: 0, HO: 1};Rationale for this is here but you have to the reverse lookup in your own JS code. There are lots of easy solutions for this. I used the one at https://stackoverflow.com/a/59360329/449347 i.e.
Generic reverse mapper function ...
export function getKey(map, val) { return Object.keys(map).find(key => map[key] === val);}UT ...
import { Bar } from "js/proto/bar_pb";expect(getKey(proto.foo.Bar.Myenum, 0)).toEqual("HEY");expect(getKey(proto.foo.Bar.Myenum, 1)).toEqual("HO");expect(getKey(proto.foo.Bar.Myenum, 99)).toBeUndefined();
