Hotel API

This is not a finished API. This repository is meant for YOU to learn to code backend properly. That is by constantly testing the code using proper testing suite, not constantly opening up Postman and hit the URL over and over again just to have the happy flow working. Please read this README file completely.

It is encouraged not to run the application during the time you are developing it. Trust me, it won't run as you expect it to be. Rather, do software testing.

To learn what software testing is, watch Fireship's video on Software Testing. If you don't like watching video, you can read this article from IBM.

As I said it before, the application is not finished yet. You can go ahead and fork or clone this repository, and open your favorite code editor or IDE for Node.js development, and search the whole repository for TODO and todo. There are a lot of things that you can work on, from the application side and the testing side. If there are no TODO on the file, it means (probably) the file is completed and should (again, probably) not be touched.

Directory Structure

If you open the src directory, you will be most likely to confused on what's the architecture pattern that we are using. You can call it whatever you want. Modified version of Model-View-Controller, or trimmed-down version of Onion Architecture.

Directory	Description
Primitive	Domain models that can be shared across layers. You can import this into business, presentation, or even repository.
PresentationInterfaces	Interface for defining Presentation layer
Presentation	Presentation layer that implements interface defined from PresentationInterfaces. This layer only accept user input from the outside world, convert into a common model that is accepted by the Business layer, calls the Business method/function, convert the returned value from the Business layer into a model that is accepted by the user as the response.
BusinessInterfaces	Interface for defining Business layer
Business	Business layer. It does not care about the Presentation layer. It only knows the interface of Repository layer. It calls required methods from the Repository layers as a part of the business process, and convert them into a common model.
RepositoryInterfaces	Interface for defining the Repository layer.
Repository	Repository layer. Handle data sources, third party APIs, object storage, message queue, and more. It should provide basic functionalities to do things that are related to data.

Development Guide

Install Node.js version v18 or higher.

Install Docker Desktop. Later on, you will need this to run your local instance of PostgreSQL database.

Install Editorconfig plugin for your code editor (or IDE). This is meant for replacing Prettier for more a more convenient way, without the hassle of executing Prettier or fighting consistently with Prettier's formatting.

• JetBrains (https://plugins.jetbrains.com/plugin/7294-editorconfig/)
• Visual Studio Code (https://marketplace.visualstudio.com/items?itemName=EditorConfig.EditorConfig)
• Vim (https://github.com/editorconfig/editorconfig-vim)
• Sublime (https://github.com/sindresorhus/editorconfig-sublime)

Install Node Modules dependencies:

npm install

Generate Prisma client:

npm run prisma:generate

Start your local PostgreSQL instance with Docker:

docker compose up -d

Migrate Prisma tables:

npm run prisma:migrate

Now you can code in peace. A few other available commands are:

Run unit and integration tests:

npm run test
# OR
npm run coverage

Run ESLint to fix your code style:

npm run lint

Compile the application to JavaScript:

npm run build

Start your application (you must compile it first):

node -r dotenv/config dist/index.js

Contribution

Contribution that are meant for completing the API and test suites will be rejected. This repository is meant for other people to practice anyway. Other contributions are welcome.
