Deploy to surge.sh on Travis-CI commits

Basically this: Integrating with Travis CI

TL;DR:

This repo is a simple test of pushing a new site to surge.sh from Travis-CI hooks for various commits.

The following .travis.yml snippet shows the script and after_script sections:

script:
  - npm run build

after_script:
  - npm run deploy

On each commit, Travis-CI will run npm run build (from the package.json's scripts section). If that command is successful, the after_script tasks will get called.

Here's a quick look at the relevant package.json bits:

  "scripts": {
    "build": "node index",
    "deploy": "scripty"
  }

You can see here that npm run build script will call $ node index which generates the dist/index.html file that we'll be deploying to surge.sh. The npm run deploy script uses the scripty module to call the /scripts/deploy shell script.

#!/usr/bin/env sh

echo "Hello from scripty"
echo $TRAVIS_PULL_REQUEST

if [ "$TRAVIS_PULL_REQUEST" = "false" ]; then
  surge --project ./dist --domain auto-deploy-test.surge.sh
else
  echo "This is a PR, not deploying"
fi

Here we have a couple pointless echo statements, and a clever if statement which determines if we're looking at a pull request or merging into master. If the current build is a pull request ($TRAVIS_PULL_REQUEST will be a number), we want to ignore it and not deploy to surge.sh since we don't want a new build deployed until a PR lands in the master branch. If the current build is NOT a pull request ($TRAVIS_PULL_REQUEST will be "false"), we use the surge.sh CLI to deploy the ./dist directory to our custom domain.
