Application Architecture

For a more comprehensive documen about this application's archietecture, view the Project Proposal.

The Gateway is an API gateway, Spring Boot project that handles routing and load balancing.

The View layer is an Angular App with 3 distinct components, auth, recipe, and cookbook.

The API layer is comprised of Spring Boot applications for auth, recipes, and cookbooks.

The Data layer is a Postgres database, which each API that requires it has it's own database within.

This is the architecture diagram for this project:

Running Locally

This project is a host of microservices. Therefore, to run this locally, there are several projects that need to be run.

Important The Gateway uses both HTTPS & HTTP, but to avoid a multitude of stack-traces when running this locally due to an invalid / unknown certificate, please follow the instructions provided in this document specific to the gateway project.

You have two options for running this project locally.

1. Launch everything via Docker. (Ideal for running the app)
2. Launch each service individually. (Idea for localhost development)

No matter which option you choose, after starting the app, it'll be accessible at http://localhost:8080

Launching Via Docker

Prerequisites - Docker must be installed on your machine.

This way leverages the Docker Compose Yaml in the root of the project directory.

From the project root, simply run:

docker-compose pull && docker-compose up

Launching All Apps Indivudually

Spring Boot Microservices

The microservices are written with Spring Boot, and so they bring along an embedded Tomcat or Netty server to run on.

Prerequisites - Java must be installed on your machine.

The following spring boot microservices must be run:

1. Gateway - this is an API gateway and Reactive/Netty router. - Port 8080
2. Auth API - this is an authorization api that tracks users who have logged in.
   It will eventually provide authorization for actions that require it. - Port 8181
3. Recipe API - this is a microservice that integrates with a 3rd party recipes api and handles some translation before service recipes to the front end. - Port 8282
4. Cookbook API - this is a microservice that allows users to save and view their own cookbook - essentially just a collection of recipes. It currently creates a cookbook with a list of recipe ids, associated to a specific user. - Port 8383

From the directory of each of these projects, you can run the following command to launch them:

./gradlew bootRun

Angular Application

The UI is written as an angular app, so running it locally relies on the angular cli.

Prerequisites - The Angular CLI must be installed on your machine.

the Recipe Oragnizr UI is an angular application, and can be run locally with the following command:

ng serve --disable-host-check

--disable-host-check is required because the angular cli runs the app on port 4200, but it must be served through the gateway on port 8080.

Database

You will also need Postgres running. See the Postgres Instructions below.

Postgres SQL

Postgres SQL is used locally for development via a docker container. The root docker-compose.yml is responsible for declaring all necessary localhost development dependencies.

To launch Posgres locally, ensure you have docker installed for your OS, then from this directory, simply run:

docker-compose up postgres

# or launch it in the background

docker-compose up -d postgres

If you need a mechanism to view the data, there is a pgadmin container included with the project which can serve as a viewer of the database. Use the following command to launch it.

docker-compse up pgadmin

To log in, the user name is: [email protected] and the password is password.

Swagger API Docs

This section requires running the app to be running. See Running Locally for additional details. Note, this is a supporting feature of the application, but is not the application itself! Swagger is an api documentation tool that provides for machine (and human) readable specifications of your application. For more information, see their official website!

With the full application stack running locally, you are able to visit http://swagger.127.0.0.1.xip.io:8080 to view API documentation for the various APIs.

Select a spec (AKA, toggle between the different API applications) in the top right of the page, and then open up either a controller to see the various API calls that are available, or the models to see the objects that are sent back and forth between the APIs and the UI.

A static reference to the models produced by this application can be found in the Swagger Model document.

Deployment

This project is deployed via travis-ci directly to the google cloud compute engine!

It is deployed on each push (and successful build) of the master branch. See the below diagram for a break-down of the CI/CD flow for this project.

This application will be hosted at http://recipe-organizr.me until this practicum has been completed.

This application is currently not hosted anywhere, but there are plans to transform this app to a desktop app of some sorts so that everyone will still be able to enjoy this if thy want! In the meantime, follow the installation steps above to run this application for development!

For additional details on this remote deployment, see gcp configuration.
