angular-express

Introduction

Extensible, reliable and modular starter project for Angular 2 (and beyond) with Angular CLI, Express and PM2 Daemon. Production Ready Full-stack.

Want to have comfortable full-stack Angular development with Express? If YES then, welcome to Angular Express!

angular-express provides the following features:

• Allows you to painlessly update of already existing project.
• Official Angular CLI features support.
• Ready to go, statically typed build system for working with TypeScript.
• Production and Development builds.
• Server Side testing with Mocha and Chai
• End-to-end tests with Cypress.
• Provides full Docker support for both development and production environment
• Following the best practices.
• Share interfaces between UI and Server
• Support for Angular Mobile Toolkit
• Contain examples with MySQL, PostgreSQL, Redis
• Express Node.js server for production/development build API.
• PM2 daemon for a server running.
• Nginx configuration file for your server.

Fast start

git clone --depth 1 https://github.com/vyakymenko/angular-express
cd angular-express
# install the project dependencies
$ npm install
# watches your files and uses livereload by default
$ npm start

# dev build
$ npm run build.dev
# prod build
$ npm run build.prod

# run server in daemon mode
$ npm run run.prod

Express Server

Express server run for prod build.

# run Express server in watch mode
$ npm run server.run

Daemonize Server

For daemonize your server I propose to uze PM2.

# before daemonize production server `npm run build.prod`
$ npm run.prod

# restart only your project
$ pm2 restart <id>
# restart all project on daemon
$ pm2 restart all

# in cluster mode ( example 4 workers )
$ pm2 start dist/server/app.js -i 4

More details about PM2

How to update

git remote add upstream https://github.com/vyakymenko/angular-express
git pull upstream master

Running tests

# Server Unit Testing
$ npm run test.server


# UI Unit Testing
$ test.ui

# Development. Your app will be watched by karma
# on each change all your specs will be executed.
$ npm run test.ui.watch
# NB: The command above might fail with a "EMFILE: too many open files" error.
# Some OS have a small limit of opened file descriptors (256) by default
# and will result in the EMFILE error.
# You can raise the maximum of file descriptors by running the command below:
$ ulimit -n 10480

# e2e (aka. end-to-end, integration)  - In two different shell windows
$ npm run e2e

# e2e live mode - Using Cypress app - In two different shell windows
$ npm run e2e.live

Dockerization

The application provides full Docker support. You can use it for both development and production builds and deployments.

Please note that prod and dev are built into their own separate image, which can lead to unexpected differences in the npm dependencies and the state of the sources in the container, if you are not familiar with Docker. See below.

Please also note that karma tests (npm test) are independent from the docker environment. Even if an angular-express container is up and running, karma will run in the context of your local npm install, which may differ from that of the container. In fact, the docker containers don’t have karma installed at all.

Cypress tests are however fully supported and recommended to test the app served by either the dev or prod docker containers.

Development build and deployment

The dev image only contains the npm libraries installed, but not the sources. The sources are mounted at runtime, via a docker shared volume, which allows for the live-reload feature to work.

To start the container, use:

$ docker-compose -f docker-compose.dev.yml up -d   # optional: --build, see below

Now open your browser at http://localhost:4200

Production build and deployment

TODO

Updating dependencies and sources

If you are not already familiar with Docker, please note that for both Dev and Prod docker environments, updates to npm dependencies will be visible only after re-building the image and restarting a new container from it.

In Dev environment, this only applies to npm dependencies, since the sources are mounted as a shared directory. In Prod environment, this applies to any change in the project.

To force docker-compose to rebuild the image before starting the container, use the –build flag:

$ docker-compose -f docker-compose.dev.yml up -d --build

How to configure my NginX

Reverse Proxy NginX Config Example

server {
    listen 80;

    # App Web Adress Listener
    server_name www.example.com example.com;

    location / {
        # Port where we have our daemon `pm2 start app.server.js`
        proxy_pass http://example.com:9000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}
