While only useful for the adventurous cherishing an aversion to [generated static code](https://github.com/dcodeIO/protobuf.js#command-line), it's also possible to use the Reader/Writer interface directly using just the [minimal runtime](https://github.com/dcodeIO/protobuf.js/tree/master/dist/runtime) to build custom encoders and decoders that work accross modern to ancient browsers and, of course, node:

var writer = protobuf.Writer.create();

var buffer = writer

.uint32(/* id */ 1 << 3 | /* wireType */ 2)

.string("hello world!")

.finish();

var reader = protobuf.Reader.create(buffer);

while (reader.pos < reader.len) {

var tag = reader.uint32();

switch (/* id */ tag >>> 3) {

case 1:

console.log(reader.string());

break;

default:

reader.skipType(/* wireType */ tag & 7);

break;

}

}
