Node Scaffolding now supports pre and post build scripts!

We have just released a new version of the Node scaffolding that supports scripts defined in package.json!

It is common for Node applications to include scripts in their package.json files like so:

package.json

"scripts": {
	"start": "react-scripts start",
	"build": "react-scripts build",
	"test": "react-scripts test --env=jsdom",
	"eject": "react-scripts eject"
}

The Habitat Node Scaffolding now supports these scripts out of the box.

Let’s take it for a test run:

One of my favorite sample React apps is the Pokedex by Ali Gasymov.

Let’s Habitize this application and deploy it in a Docker container!

First, clone the Github repo:

$ git clone git@github.com:alik0211/pokedex.git
$ cd pokedex

Now install the dependencies:

pokedex

$ npm install

Check out the package.json – notice the scripts section? We will be able to run these to start, build, etc. the application through the Node Scaffolding.

package.json

{
	"name": "pokedex",
		"version": "1.1.5",
		"private": true,
		"dependencies": {
			"react": "^16.0.0",
			"react-dom": "^16.0.0",
			"react-redux": "^5.0.6",
			"redux": "^3.7.2",
			"redux-thunk": "^2.2.0"
		},
		"devDependencies": {
			"react-scripts": "1.0.10",
			"redux-logger": "^3.0.6"
		},
		"scripts": {
			"start": "react-scripts start",
			"build": "react-scripts build",
			"test": "react-scripts test --env=jsdom",
			"eject": "react-scripts eject"
		}
}

Let’s Habitize this app:

$ hab plan init -s node
$ hab studio enter
[1][default:/src:0]# build

Currently, this only builds your application as a HART package – scripts within the package.json file will run when installing this package to wherever you want to run it.

Once the build completes, export your new HART package as a Docker image:

[1][default:/src:0]# $ hab pkg export docker ./results/your_new_hart_file.hart
[1][default:/src:0]# $ exit

Now, start up a new container with your container image

$ docker run -it -p 8000:8000 your_origin/pokedex

Then navigate to http://localhost:8000 in your browser and you should see a running pokedex!
