The source code is not completely clean for the architecture concept, but all aspects are evaluated.

PoC - Flexible web application architecture

Motivation

This project demonstrates a scalable, flexible, and framework-neutral JavaScript web application architecture.

Addressee

This document is intended for everyone who cares about the following criteria:

  • Learnability
  • Controllability
  • Universality
  • Flexibility
  • Scalability
  • Durability

Rules

  • Vanilla/TypeScript code is universally applicable
  • use the relevant features directly without "instantaneous water heaters"
  • only the connection layer between controller and material design is framework-specific

Introduction

We write always the same application with different JavaScript-Frameworks. Here you can find a Demo-Link.

* It is difficult to keep focus with Cypress as it is more a nice tool than an effective tool. It is expected that a lot of time will be invested to justify the requirements of a project.

Devtools

Installation

Run npm install in the bash. If there any problems with the installed dependencies, you can reinstall everything with npm run reinstall.

Guide

Usual usage without CLI

Normally the binaries npm are used to execute the scripts.

Serve

Currently the following frameworks are available:

  • angular
  • angularjs
  • aurelia
  • inferno
  • preact
  • react
  • svelte
  • vanilla
  • vue

Use this command to serve the application: npm run serve[ <framework> [ -- --open]]

For example:

  • npm run serve -f inferno
  • npm run serve -f inferno -- --open

The optional option --open open the app in you default browser.

Build

Use this command to build the application: nom run build[ <framework>]

For example:

  • npm run build inferno

Command Line Interfaces

You should know that this project should show the generic architecture concept. The showcase with CLI usage demonstrates the independent codebase.

Angular CLI

Currently the Angular CLI is partially supported. You must delete all non-angular sources from the src/ folder.

  • npm run ng:serve executes ng serve
  • npm run ng:build executes ng build --prod
Installation

Please use primary this documentation: https://angular.io/cli

Vue CLI

Currently the Vue CLI is partially supported. You must delete all non-vue sources from the src/ folder.

  • npm run vue:serve executes vue-cli-service serve src/vue.ts
  • npm run vue:build executes vue-cli-service build src/vue.ts

You must remove the root slashes!

Before:

<script src="/js/chunk-vendors.c6f5dd88.js"></script>
<script src="/js/app.c9cc3ddc.js"></script>

After:

<script src="js/chunk-vendors.c6f5dd88.js"></script>
<script src="js/app.c9cc3ddc.js"></script>

.

Installation

Please use primary this documentation: https://cli.vuejs.org/guide/installation.html

Testing

Unit-Test

Execute all unit tests with npm run test or npm run test -- --watch.

Snapshot-Test

Currently not supported.

E2E-Test

Execute all e2e tests with npm run e2e or npm run e2e --headless for running headless.

Documentation

Storybook is a realy nice tool to document the components and there usage.

  • npm run storybook:serve for serve the documentation
  • npm run storybook:build for build the documentation

Open topics

  • Clean up the code for the architectural concept. ✔️
  • Use observables to trigger rendering in correct cases. ✔️
  • Prepare the project for unit and e2e testing. ✔️
  • Extends the application with adding measurements. ⌛
  • Add router to the application context. ✔️
  • Create a cheat sheet for the application architecture concept. ✔️
  • Provide a PWA manifest for each framework artifact. ✔️ // Use workbox
  • Coverage test in the build pipeline. ✔️
  • E2E tests with Cypress instead of Nightwatch. ❌ // E2E-Testing in headless mode, works. ✔️
  • Add filters to the application context. ✔️

Known bugs

  • In the parallel app execution the params routing breaks. ✔️

Gained knowledge

Moment increases the artifact size

Moment magnifies the build artifact immensely.

Artifact analyser

If that's interesting ...

Needs additional devDependency:

  • webpack-bundle-analyzer: ~3.6.0

Usage: npm run build angular -- --analyser

Artifact minimisation (⨻ outdated)

The benefit of this function was too small.

There are some optional plugins to minimize the build artifacts in webpack. However, these options are not really better than the default webpack setup.

Needs additional devDependencies:

  • closure-webpack-plugin: ~2.0.0
  • google-closure-compiler: ~20190929.0.0
  • terser-webpack-plugin: ~2.2.0
  • uglifyjs-webpack-plugin: ~2.2.0

Usage: npm run build react -- --minimizer terser
