gRPC-Web Demo

Deployed, Check it out!

Please read the Medium Story first.

This repo contains microservices written in Go (gRPC Servers) and their envoy proxy configurations for establishing connection through gRPC-Web with the client (UI). gRPC Unary and gRPC Server-side Streaming examples are available in the services.

	gRPC Unary	gRPC Server-side Streaming
Catalog μS	✅
Offer μS		✅
Order μS	✅	✅

Installation

Let's start!

Please make sure Docker is running.

First, clone the repository

git clone https://github.com/uid4oe/grpc-web-demo.git

Then, open a terminal window from the root of the project. We will just need to create network & execute the docker-compose command

docker network create grpc-web-demo-alva-net
docker-compose up -d

At this point everything should be up and running!

You can track service logs from containers: catalog, offer, order.

You can access to UI at

http://localhost:3000

Additionally, you can check gRPC-Web Demo UI which has the UI code for this demo.

Local Development

For running services in your local environment, we will need MongoDB, PostgreSQL, and envoy proxies (gRPC-Web related). We can use local.yml file for setting up MongoDB, PostgreSQL, Catalog Envoy, Offer Envoy, Order Envoy and UI.

Open a terminal in the project root folder, then;

docker network create grpc-web-demo-alva-net
docker compose --file local.yml up -d

Now let's start microservices locally.

sh start-local.sh

That's great. Everything is set. You can track service logs from your IDE/terminal.

You can use the app through UI (container: ui) at

http://localhost:3000

If you also want to run UI locally which I would prefer for experimenting full-stack, please stop the container: ui and then follow the readme at gRPC-Web Demo UI.
