Where to find Protobuf Javascript tutorial?

[hce h]

Hi,

We are using javascript for web front end development and we are using the protobuf to communicate with backend web applications. Currently we are  using GO to do protobuf communication between the backend application server which runs on C++ and the front end  running on Javascript, but I've just found there is a protobuf interface for Javascript as well, we can actually simplify the process directly to use javascript to fetch the protobuf messages with backend application without GO. Is it a good idea? I have since been investigating the javascript protobuf capability but I could not find javascript progotbuf examples and tutorials, the link https://developers.google.com/protocol-buffers/docs/tutorials shows tutorials for every program language except javascript. Appriciate anyone could point me likes for Javascript prototobuf examples and tutorials.

I have also downloaded protobuf-js-3.3.0.zip, but it looks like it is similar to protobuf-cpp-3.3.0.tar.gz which I built on Linux platform, I guess the protobuf-js-3.3.0.zip is not the binary for javascript, link the C++ I need to build it as well, correct?

Thank you.

Kind regards,

protobuf-js-3.3.0.zip is the original source code for C++ + Javascript. If you only need the already-built protobuf js package, try npm google-protobuf:

https://www.npmjs.com/package/google-protobuf

Note that you will need to download protoc binary to do the code generation.

 

Thank you.

Kind regards,

Thanks for the response. If I understand it correctly, the js package contains a js directory which is pre-built javascript libraries. I built the C++ package and I can use the C++ package to generate javascript library by running "protoc --js_out=library=myproto_libs,binary:. proto3_test.proto"

I am not going to use the node, then I cannot use the npm either, not quite sure if I could install javascript libraries manually without npm?
