Polymer Snippets for Sublime

Install

To install through Package Control, search for Polymer & Web Component Snippets. If you still don't have Package Control in Sublime Text, go get it. It's pure awesomeness.

If you don't use Package Control, you can download the package and put it manually inside your Packages directory. It should work but will not update automatically.

Elements

Type the name of any core-* or paper-* element, then hit tab to auto complete. Ex:

OR, start typing the prefix for an element and hit ctrl+space to fuzzy search for a completion. Ex:

Polymer

[pe] polymer element

<polymer-element name="$1" attributes="$2">
  <template>
    <style>
      :host {
        display: block;
      }
    </style>$3
  </template>
  <script>
    Polymer({
      $4
    });
  </script>
</polymer-element>

[pen] polymer element noscript

<polymer-element name="$1" noscript attributes="$2">
  <template>
    <style>
      :host {
        display: block;
      }
    </style>$3
  </template>
</polymer-element>

[pes] polymer element with external stylesheet

<polymer-element name="$1" attributes="$2">
  <template>
    <link rel="stylesheet" href="$3.css">$4
  </template>
  <script>
    Polymer({
      $5
    });
  </script>
</polymer-element>

[hi] html import (I use this one a lot)

<link rel="import" href="${1:bower_components}/${0}/${0}.html">

[hic] html import core-* element

<link rel="import" href="${1:bower_components}/core-${2}/core-${2}.html">

[hip] html import paper-* element

<link rel="import" href="${1:bower_components}/paper-${2}/paper-${2}.html">

Web Components

[tm] template

<template$1>$0</template>

[ce] custom element

var ${4:tmpl} = document.querySelector('${5:template}');

var ${1:WidgetProto} = Object.create(HTMLElement.prototype);

${1:WidgetProto}.createdCallback = function() {
  var root = this.createShadowRoot();
  root.appendChild(document.importNode(${4:tmpl}.content, true));
};

var ${2:Widget} = document.registerElement('${3:my-widget}', {
  prototype: ${1:WidgetProto}
});

HTML

[ph] HTML template with Web Components polyfill

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">

  <title>${1}</title>
  <meta name="description" content="${2}">

  <!-- Mobile -->
  <meta name="viewport" content="width=device-width, initial-scale=1, user-scalable=no">

  <!-- Chrome / Android -->
  <meta name="mobile-web-app-capable" content="yes">
  <meta name="theme-color" content="black">
  <link rel="icon" href="icon.png">

  <!-- Safari / iOS -->
  <meta name="apple-mobile-web-app-capable" content="yes">
  <meta name="apple-mobile-web-app-status-bar-style" content="black">
  <link rel="apple-touch-icon-precomposed" href="apple-touch-icon.png">

  <!-- Web Components -->
  <script>
    if ('registerElement' in document
    && 'createShadowRoot' in HTMLElement.prototype
    && 'import' in document.createElement('link')
    && 'content' in document.createElement('template')) {
      // Native WC support. Do nothing
    } else {
      document.write('<script src="/bower_components/webcomponentsjs/webcomponents.js"><\/script>');
    }
  </script>
</head>
<body unresolved>
  $0
</body>
</html>

CSS

[sh] ::shadow

::shadow ${2:target} {
  $0
}

[sd] /deep/

/deep/ ${2:target} {
  $0
}

[cn] content::content

${1:content}::content ${2:target} {
  $0
}

[ho] :host

:host$0

[hc] :host-context()

:host-context($0)

[pf] polyfill-next-selector

polyfill-next-selector { content: '${1::host > .foo}'; }$0

What about Emmet?

In order to play nice with Emmet I've included a Emmet.sublime-settings file which will enable the use of Shadow DOM CSS selectors. If this causes weirdness please file an issue.
