ember-polaris

ember-polaris is an ember-cli addon to make Shopify's Polaris design system accessible to Ember developers.

Status

NOTE: This addon is no longer maintained. If you currently use or depend on this library we strongly recommend creating a fork and maintaining it yourself. Not all Polaris components have been implemented or implemented completely, check the component list for a list of those components which are currently available.

Compatibility

Ember.js v3.16 or above
Ember CLI v2.13 or above
Node.js v10 or above

Installation

Install ember-polaris using ember-cli:

$ ember install @smile-io/ember-polaris

Styles

This addon will install ember-cli-sass in the host app. It will also set up your app's app/styles/app.scss to @import "ember-polaris";, creating the file if it does not already exist.

Icons

For icons to work you will need to:

copy Polaris SVG's into a folder in public, ex: public/assets/images/svg/polaris
install ember-svg-jar
add the following ember-svg-jar options to your ember-cli-build.js:

// ember-cli-build.js
var app = new EmberApp(defaults, {
  ...

  svgJar: {
    strategy: 'inline',
    inline: {
      stripPath: false,
      optimizer: {
        removeDimensions: true,
      },
      sourceDirs: [
        'public/assets/images/svg',
      ],
    }
  },

  ...
});

Template compiler

If your app does not already import ember-template-compiler, you may get an error similar to this one when passing a hash of componentName and props into one of the ember-polaris components:

Uncaught TypeError: _ember.default.HTMLBars.compile is not a function

If that happens, you need to add an import statement to its ember-cli-build.js.

// ember-cli-build.js
app.import('node_modules/ember-source/dist/ember-template-compiler.js');

NOTE: This setup will be handled by ember-polaris in the future.

Usage

ember-polaris provides a set of Ember components intended to implement the same behavior and functionality as the Shopify Polaris React components. In general the usage can be inferred from the Polaris component documentation, with some exceptions as described below.

Differences with Polaris React components

We have tried to keep the components provided by ember-polaris as similar to the original Polaris React components as possible. However, there are cases where it makes sense to do things in a more Ember-friendly way, and where this is true we will describe the ember-polaris usage and how it differs from the original Shopify components.

General Differences

`children` property

A large number of the Polaris React components have a children property listed in their documentation. In these cases, the corresponding ember-polaris component can be given a text attribute which will take the place of the children property and specify the text to be rendered by the component. Alternatively these components can be used in block form to achieve the same result. Note that the block content will take precedence over the text attribute (if one is supplied):

{{polaris-button text="Attribute text"}}
 => renders a button with the content "Attribute text"

{{#polaris-button}}
  Block text
{{/polaris-button}}
 => renders a button with the content "Block text"

{{#polaris-button text="Attribute text"}}
  Block text
{{/polaris-button}}
 => renders a button with the content "Block text"

`element` property

Some Polaris React components accept an element property which changes the tag rendered by the component. In ember-polaris, this is replaced by the tagName attribute unless otherwise noted. This attribute cannot be dynamic - the following code would cause an error:

{{#polaris-display-text tagName=displayTextTagName}}
  Displays fine to start with...
{{/polaris-display-text}}

{{#polaris-button onClick=(action (mut displayTextTagName) "h5")}}
  ... but clicking this button will cause an error
{{/polaris-button}}

`actions` property

Some Polaris React components accept an actions property as a list of actions which can be performed. In ember-polaris, this is renamed to avoid collisions with the Ember actions hash. The new name will be different based on the component - check the documentation for the specific component to find out what attribute to pass the actions list as.
