Uncle Bob's clean architecture implementation in Typescript, with Express as Web Detail

version: 'v1.0.0'

Description

Based on Uncle Bob's Clean Architecture, i tried to an implementation in Typescript with "screaming architecture" in folders and files.

First, i use separated components with an example :

./src/Components/User

As Web Detail, i used my own "Node.js server with express framework, craftsmanship way" :

Clean project structure
Tests Driven Development
Test Coverage
Copy/paste detection

./src/FrameworkAndDrivers/Web/express

https://github.com/Stayfi/nodejs-server

Project structure

./scripts: Scripts used by package.json

./src: Application source code

./src/ComponentInterfaces: Clean architecture Interfaces, to represent the Uncle Bob's interfaces schema

./src/Components: Components, as "Packages by feature" with all feature use cases

./src/Components/User/Entities

./src/Components/User/InterfaceAdapters

./src/Components/UseCases/User

./src/Components/UseCases/createUser: "create user" use case for "User" feature

./src/FrameworkAndDrivers

./src/FrameworkAndDrivers/DB/MongoDB: MongoDB implementatin with connexion and repositories

./src/FrameworkAndDrivers/Web/express: Node.js server with express ( https://github.com/Stayfi/nodejs-server )

Implementation schema

Initialize the view to render viewModel datas with nunjucks template

./src/FrameworkAndDrivers/Web/express/app/UsesCases/User/createUser/views/createUserView.ts

Entity gateway implementation with MongoDB

./src/FrameworkAndDrivers/DB/MongoDB/User/user.model.ts

Deliver initialize controller with entity gateway and view, then execute controller with controllerRequestModel sended by Web implementation (express)

./src/FrameworkAndDrivers/Web/express/app/UsesCases/User/createUser/delivers/createUserDeliver.ts

Controller initialize presenter with view received, initialize interactor with entity gateway and presenter, then execute interactor with controllerRequest datas mapped to requestUserModel

./src/Components/User/InterfaceAdapters/createUserController.ts

Interactor execution do the business job with entity, entity gateway implementation, datas and then presente responseModel data

./src/Components/User/UseCases/createUser/CreateUserInteractor.ts

Presenter, execute view renderer with responseModel data mapped to viewModel data

./src/Components/User/InterfaceAdapters/createUserPresenter.ts

Install

Dev installation

Go to the project directory and do

    $ npm run install:dev

Production installation

Go to the project directory and do

    $ npm run install:prod

Start the project

Dev running

    $ npm run dev

Open your browser to : http://localhost:3000

Prod running

    $ npm run start

Open your browser to : http://localhost:8080

Running tests

    $ npm run test

Or simply :

    $ jest

Running coverage

    $ npm run coverage

Running copy/paste detection

    $ npm run jscpd

Running tslint

With fix :

    $ npm run tslint:fix

Clean the project

It remove all folders generated by build, test and coverage.

    $ npm run clean
