Syntax highlight template literals as HTML in Sublime Text 3 for Vue.js components, Vue app instances, or other client-side JavaScript. Particularly useful for the .page.js and .component.js files in your Sails app or other Parasails project. No grunt-ing, gulp-ing, webpack-ing, brunch-ing, or supper required.

name: JavaScript (Parasails)
file_extensions:
  - component.js
  - page.js
scope: source.js.parasails
contexts:
  main:
    - match: ""
      push: scope:source.js
      with_prototype:
      - match: 'template\s*\:\s*`\s*'
        push:
          - meta_content_scope: text.html.basic.embedded.js
          - include: 'scope:text.html.basic'
          - match: '`\s*,?\s*$'
            pop: true

Good job! I followed the instructions and it worked. I only had to manually select syntax highlighting for Javascript (Parasails).
Thanks!
