Introduction

This is a proof of concept that demonstrates the ability to share a Typescript package with core functionalities and business logic between an Angular web app and an Ionic mobile app.

Please check the Medium article Hybrid mobile apps: sharing logic between Angular and Ionic apps for more info.

Goals:

• encapsulate all the business logic in a core module, based on @ngrx/store,
• keep specific view layout, markup and navigation logic in the app projects.

Note: @ngrx/store is a RxJS powered state management inspired by Redux for Angular apps. It's currently the most popular way to structure complex business logic in Angular apps.

Running the apps locally

# Clone the repo
git clone https://github.com/benorama/ngrx-demo-apps.git

Prerequisites:

• Typescript 2.0+
• Angular CLI
• Ionic CLI

Note: ngrx-demo-core module is shared between the apps with npm link but it could be published to npmjs and be used as a regular dependency.

ngrx-demo-core module

First, compile ngrx-demo-core shared module.

It is based on official Ionic module template, which supports Angular's ngc and Ahead-of-Time compiling out of the box. https://github.com/driftyco/ionic-module-template

# Go into core module directory
cd ngrx-demo-apps/core

# Install dependencies
yarn
# Or npm install

# Compile typescript into dist
yarn build
# Or npm run build

yarn link
# Or npm pack
# Or npm publish

# Note: during dev, you can use 'tsc -w'

The shared module is now installed locally and can be used in other local npm projects.

ngrx-demo-web app

Install or link ngrx-demo-core shared module and run the web app.

# Go into web Angular2 app directory
cd ../web

# Install dependencies
yarn
# Or npm install

# Create a symlink from the local node_modules folder to the global shared module symlink
yarn link "ngrx-demo-core"
# Or npm install ../core/ngrx-demo-core-0.0.1.tgz (if you used npm pack)

# Run the web app locally
ng serve

ngrx-demo-mobile app

As we did for the web app, install or link the ngrx-demo-core shared module and run the mobile app.

# Go into mobile Ionic2 app directory
cd ../mobile

# Install dependencies and typings (you can get a burger...)
yarn
# Or npm install

# Create a symlink from the local node_modules folder to the global shared module symlink
yarn link "ngrx-demo-core"
# Or npm install ../core/ngrx-demo-core-0.0.1.tgz (if you used npm pack)

# Run the mobile app locally
ionic serve
