Todo list microservices architecture application

Table of contents

Description

This project demonstrates microservices architecture based application.

Main application features:

  • gRPC APIs
  • SSL encryption between client and backend
  • users can login and register accounts
  • JWT token authorization
  • gateway API
  • logged users can create, get, list, update and delete todo list entries
  • services use MySQL databases
  • services are running in Docker containers

Application consists of three services:

  • Gateway API service - SSL encryption, JWT token verification, authorization and orchestration
  • User service - registering users, managing user accounts, authentication and JWT token generation
  • Todo service - creating, updating, deleting and querying todos

Cloning repository

git clone --recursive https://github.com/rsitko92/todo-app-microservices.git

Prerequisites

Generating interfaces

Being in root directory of project run:

sudo protos/run.sh

Generated interfaces definitions will be placed in protos/.gen directory. It is sufficient to generate they only one time.

Generating diagrams

Being in root directory of project run:

docs/diagrams/generate.sh

Generated images with diagrams will be placed in docs/diagrams/out directory.

Running tests

Before running any kind of tests (integration or end2end) generate the gRPC client and server interfaces from .proto service definitions files. See section Generating interfaces.

Running integration tests

  • User service:

    Being in root directory of project run:

    sudo user/tests/integration/run.sh
  • Todo service:

    Being in root directory of project run:

    sudo todo/tests/integration/run.sh

Running end2end tests

Being in root directory of project run:

sudo test/run.sh
