Custom Node.js with Apple's Swift Buildpack

A Custom Buildpack buildpack for Node.js based apps with Apple's Swift 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/snippet-java/nodejs-swift-buildpack.git

In order to use Swift, Node.js needs to use child_process to compile and execute swift.

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 Apple's Swift Was Added?

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

 #binaries_swift.sh
install_swift() {
  local version="$1"
  local dir="$2"
  
  CLANG_VERSION=3.7.0
  SWIFT_VERSION=2.2.1-RELEASE
  SWIFT_VERSION_=2.2.1-release
  
  local download_url="http://llvm.org/releases/$CLANG_VERSION/clang+llvm-$CLANG_VERSION-x86_64-linux-gnu-ubuntu-14.04.tar.xz"
  echo "Downloading clang [$download_url]"
  curl  --silent --fail --retry 5 --retry-max-time 15 -j -k -L "$download_url" -o /tmp/clang.tar.xz || (echo "Unable to download clang; does it exist?" && false)
  echo "Download complete!"
    
  echo "Installing clang"
  mkdir -p /tmp/clang
  mkdir -p $dir/clang
  xz -d -c /tmp/clang.tar.xz | tar x -C /tmp/clang
  rm -rf $dir/clang/*
  mv /tmp/clang/clang+llvm-$CLANG_VERSION-x86_64-linux-gnu-ubuntu-14.04/* $dir/clang
  chmod +x $dir/clang/bin $dir/clang
  echo "Installation complete!"
  
  local download_url="https://swift.org/builds/swift-$SWIFT_VERSION_/ubuntu1404/swift-$SWIFT_VERSION/swift-$SWIFT_VERSION-ubuntu14.04.tar.gz"
  echo "Downloading Swift [$download_url]"
  curl  --silent --fail --retry 5 --retry-max-time 15 -j -k -L "$download_url" -o /tmp/swift.tar.gz || (echo "Unable to download swift; does it exist?" && false)
  echo "Download complete!"
  
  echo "Installing swift"
  mkdir -p /tmp/swift
  mkdir -p $dir
  tar xzf /tmp/swift.tar.gz -C /tmp/swift
  rm -rf $dir/*
  mv /tmp/swift/swift-$SWIFT_VERSION-ubuntu14.04/usr/* $dir
  chmod +x $dir/bin
  echo "Installation complete!"	
}

Then, PATH 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.
