Here is a GIF of how the app looks like:

Tech stack

One of the key motivations to build this app was to experiment with different technologies. The technologies used to build this app are explained in the following sections:

Service definitions

• Written using protobuf (proto3 syntax)
• Exposes the following types of gRPC endpoints:
  • unary messages
  • server-streaming messages
  • client-streaming messages
  • bidirectional streaming messages

Application Server

• Written in Golang (v.1.14)
• Implements GRPC server

Client

• Written in Dart (v2.7.2)
• Using the Flutter framework
• Compiled for multiple platforms

Platform support

• Android
• iOS
• Web-app (partial support)
• MacOS (partial support)

Middleware

• HTTP-GRPC proxy implemented using gRPC-Gateway
• Published Swagger UI on top of HTTP-GRPC proxy

Telemetry

• Prometheus to collect metrics
• Grafana to visualize metrics

Server deployment

• Created as a docker image
• Tagged docker image hosted on dockerhub
• Running in an elastic Kubernetes cluster
• Hosted on Azure Kubernetes Service

Test clients

• gRPC client written in Node.js
• gRPC client written in Golang

Client deployment

• Android apk available on thhe releases page: https://github.com/kaushikchaubal/home-recipes/releases/tag/0.0.1

Architecture

The final architecture of the designed system is as seen here:

Digital whiteboarding

• As part of the implementation stage, Miro was used as the digital whiteboard of choice
• The miro board associated with home-recipes can be found here: https://miro.com/app/board/o9J_ktw-EKc=/
• You will find details of multiple things including architecture design, the API definitions and UI mocks details
