## protobuf python-to-js demo

Serializing data in python and deserializing in the browser using [protobuf](https://developers.google.com/protocol-buffers/) and [protobufjs](https://www.npmjs.com/package/protobufjs).

### How it works

- Docker container compiles `.proto` definitions to both Python output and JSON output

- Flask server serializes data according to the Python class compiled from the `.proto` file

- Flask server serves `index.html` page that does the following:

    - load the JSON object compiled from the `.proto` file

    - fetch serialized data from Flask at `/data` endpoint

    - deserialize and display on the page

### Run the demo

```sh

# Compile the message format located at io/src/addressbook.proto

docker build -t protoc .

docker run -v $(pwd)/io:/proto/io protoc addressbook.proto

# Install js dependencies

npm install

# Install python dependencies

conda env create -f environment.yml

conda activate protobuf-demo-env

# Start python server

python main.py

```
