How to set up Continuous Integration and Continuous Deployment for a Node.js Application from GitHub to Nodejitsu
In this blog post we're gonna deploy a Node.js application from a GitHub repository to Nodejitsu using Codeship.
We've set up a simple Node.js application called codefish which contains some Jasmine specs. We'll use screenshots of this application in this blog post. If you haven't got an own project to set up but you want to follow along on your computer, just fork the repository.
Together, we're gonna deploy this application to Nodejitsu using the Codeship.
First, sign in to the Codeship with GitHub. The Codeship needs access to your GitHub repositories to be able to set them up. Let's allow access.
We're back at the Codeship. Now let's create your first project.
The first step of your project setup is to select GitHub as your repository provider.
In the list of your GitHub repositories
search for the repository you want to set up and select it. In my case I search for "codefish".
Now your repository is connected and you can set up your test commands:
Codefish is a Node.js application. Therefore let's choose "Node.js" as your framework. This prepopulates the setup commands and the test commands for you.
The Codeship suggests Node.js 0.10.18, but you can use whatever Node version you like. To find out the Node version of your project, type
node -v in the Terminal.
Just copy your Node version into the
nvm install and
nvm use statements.
If you want to run Jasmine specs, please install
jasmine-node globally additionally to your node modules. In this case just add
npm install -g jasmine-node after
You don't need
npm test for your Jasmine specs, so you can comment it out by adding a hash key before the command. Instead, add
jasmine-node spec to the test commands to run your Jasmine specs.
Now let's finish your setup and go to the dashboard.
You can trigger a build for your application by pushing to your repository. Let's add the Codeship status image to the README file. I use markdown syntax to insert the image.
Now commit and push this change.
This triggered a new build on the Codeship.
You can access the build details by clicking the arrow on the right. Here you can follow the running build.
And a few seconds later your build succeeded! Great!
You see all the commands that were run. After a few initial preparation commands the Codeship ran the commands that you specified a few moments ago.
You can inspect the output of a single command by clicking on it. For the
codefish application, we can see that two Jasmine specs were run.
You've already pushed to your repository, watched your build log and got a green build. So you can finish the assistant at the top.
Now let's deploy your application to Nodejitsu. Go to your project settings by clicking on the settings icon in the projects dropdown.
Then navigate to the "Deployment" section.
As we want to deploy to Nodejitsu we click on the "Nodejitsu" button.
Now you are asked to enter your Nodejitsu username and token.
To generate your Nodejitsu token, run
jitsu tokens create codeship on the terminal.
Copy the token and insert it into your Codeship deployment configuration.
Now save your deployment by clicking on the green checkmark on the right.
From now on the Codeship will deploy your application to Nodejitsu everytime you push to your GitHub repository.
You still need to tell Nodejitsu which subdomain you want to deploy to and how to run your application.
In my case, I added
"subdomain": "codefish" and a
"node start.js". Please adapt these parameters to whatever fits your app.
This way Nodejitsu will know where to publish your app and how to launch it.
Now you can commit and push this change
And immediately another build will start running on the Codeship. Let's go back to your project overview.
After the commands we already know from your first build, your application also gets deployed to Nodejitsu now.
And about 2 minutes later your application is online.
When you open the URL of your Nodejitsu app now, your deployed application appears. You can find mine on codefish.nodejitsu.com.
