Custom Node.js with Oracle's JDK 8 Buildpack

A Custom Buildpack buildpack for Node.js based apps with Oracle's JDK 8 installed.

Additionally, the Cloud Foundry CLI was included in the buildpack.

This is based on the Cloud Foundry buildpack which is also based on the Heroku buildpack.

Additional documentation can be found at the CloudFoundry.org.

Usage

This buildpack will get used if you have a package.json file in your project's root directory.

cf push my_app -b https://github.com/syahrul-aiman/nodejs-java-buildpack.git

In order to use Java, Node.js needs to use child_process and execute java command such as:

const exec = require('child_process').exec;
exec("java lib/HelloWorld.jar", {shell: '/bin/bash'}, function (err, stdout, stderr) {
	console.log(stderr);
	console.log(stdout);
});

Sample application: Node.js Java BeanShell Script Executer

Options

Specify a node version

Set engines.node in package.json to the semver range (or specific version) of node you'd like to use. (It's a good idea to make this the same version you use during development)

"engines": {
  "node": "0.11.x"
}

"engines": {
  "node": "0.10.33"
}

How Oracle's JDK 8 Was Added?

The following script was added to the buildpack's compile script

 #binaries_java.sh
install_java() {
  local version="$1"
  local dir="$2"
  
  local download_url="http://download.oracle.com/otn-pub/java/jdk/8u73-b02/jdk-8u73-linux-x64.tar.gz"
  echo "Downloading JAVA [$download_url]"
  curl  --silent --fail --retry 5 --retry-max-time 15 -j -k -L -H "Cookie: oraclelicense=accept-securebackup-cookie" "$download_url" -o /tmp/java.tar.gz || (echo "Unable to download java; does it exist?" && false)
  echo "Download complete!"

  echo "Installing JAVA"
  mkdir /tmp/jdk
  mkdir $dir
  tar xzf /tmp/java.tar.gz -C /tmp/jdk
  rm -rf $dir/*
  mv /tmp/jdk/jdk1.8.0_73/* $dir
  chmod +x $dir/bin
  echo "Installation complete!"	
}

Then, PATH and JAVA_HOME was set as well.

How Cloud Foundry CLI Was Added?

The following script was added to the buildpack's compile script

 #binaries_cfcli.sh
install_cfcli() {
  local version="$1"
  local dir="$2"

  local download_url="https://cli.run.pivotal.io/stable?release=linux64-binary&source=github"
  echo "Downloading CF CLI [$download_url]"
  curl  --silent --fail --retry 5 --retry-max-time 15 -j -k -L -H "Cookie: oraclelicense=accept-securebackup-cookie" "$download_url" -o /tmp/cf.tar.gz || (echo "Unable to download cf CLI; does it exist?" && false)
  echo "Download complete!"

  echo "Installing CF CLI"
  tar xzf /tmp/cf.tar.gz -C $dir
  echo "Installation complete!"	
}

Then, PATH was set as well.
