Getting started with Node.js on Codemason

Introduction

Let’s get you started with Node.js on Codemason.

This guide will walk you through a successful deployment of a Node.js application with Codemason, from prototype to production.

This guide assumes that you already have:

  • A free Codemason account
  • Installed the Mason CLI and its dependencies
  • Installed Node.js and NPM locally

Setup

Start by installing the Mason CLI. You can use the CLI to manage and deploy your apps, view application logs and run your apps locally.

Install the Mason CLI

$ npm install --global codemason

With the Mason CLI installed, you will be able to use the mason command from your command line.

Use the mason login command to log in to Codemason:

$ mason login

Prepare your app

Let's prepare an app to deploy!

If you're new to Codemason, we recommend using our sample PHP app to complete this tutorial. However, if you want to deploy an existing app, see this guide for preparing your codebase for Codemason deployment.

Start by pulling a copy of our demo PHP project. This is just a simple quote rotator app. Every time you load the page, it will randomly select a quote from an array and display it.

$ git clone https://github.com/CodemasonHQ/getting-started-nodejs
$ cd getting-started-nodejs

You now have a git repository that contains our sample PHP app as well as a .gitlab-ci.yml and Dockerfile file. These files tell Codemason how to build and run your PHP app.

Deploy your app

Now it's time to deploy our app to Codemason.

At Codemason, developer experience is our top priority. Everything we do is about solving the problems that interrupt your flow and distract you from focusing on what counts, building great apps.

First, use the mason create command to create a Codemason app. The CLI suggest default values, but you can override them as required.

$ mason create getting-started-nodejs

Creating app on Codemason...
 ... Created application
 ... Created remote repository
 ... Added git remote codemason

This command creates an app and prepares Codemason to receive your code.

Push your changes to your Codemason Git remote. Our GitLab CI Runner will then build your Docker image and push it to the private registry, as per the build instructions in .gitlab-ci.yml.

$ git push codemason master

You can now deploy your app:

$ mason services:create getting-started-nodejs/web -p 80:80 --env-file .env

Creating service on Codemason...... done

    NAME     IMAGE                                         COMMAND     PORTS
    web      registry.mason.ci/benm/getting-started-nodejs             80:80

These commands posts Mason JSON to our API which spins up your service on your server for you.

Updating your app

Updating your app is just as easy the upgrade command.

First, let's make a change to views/index.ejs so you can leave your mark on this application.

...
  <div class="panel">
      <h1><i><%= quote %></i></h1>
      <small>
        <a href="https://twitter.com/intent/tweet?text=<%= quote.replace(/(<([^>]+)>)/ig,'') %> @codemasonhq">Tweet This!</a>
      </small>
  </div>
...

Add your changes to source control (Git)

$ git add .

Commit and push the changes

$ git commit -m "Update app"
$ git push codemason master

Run the upgrade command. Be sure to specify the service you wish to upgrade in the following format application/service.

$ mason services:upgrade getting-started-nodejs/web
