##<signin-button>

A generic sign in button element implementing the Google Sign-In guidelines

Usage Instructions

The signin-button element creates themed buttons that can be used as login buttons or as generic similarly-styled buttons.

The signin-button can make use of inbuilt providers or can be customized for others. The element has support for 'short', 'dark theme' and 'tile' (icon only) variants accessible through properties. The icons used as part of this element are rendered from SVGs using iron-icon.

To customize the element's provider, you can pass in one (or more) of the following:

• attributes such as provider, name, icon, prefix, label
• an object with the above attributes as properties
• only the provider attribute to use one of the inbuilt providers

When you use the signin-button element on its own, the inbuilt providers include:

• anonymous: For anonymous or demo users
• email: For generic email/password sign-in flows
• facebook: Facebook
• github: GitHub
• google: Google
• twitter: Twitter
• unknown: Unknown provider - this is the fallback when a match cannot be found.

These are the providers used by Firebase and should serve majority of users.

It will also import signin-button/signin-icons.html containing the following icons:

['signin:anonymous', 'signin:email', 'signin:facebook', 'signin:github', 'signin:google', 'signin:twitter', 'signin:unknown']

To access more providers, you may also import the signin-button-more-providers element. This element wraps a signin-button but adds extra less-common providers.

In the future, you will be able to add providers in a similar fashion to how iron-iconset adds icons.

Examples

Using an inbuilt provider:

<signin-button provider="google"></signin-button>

Configuring a custom provider:

<signin-button provider="linkedin" logo-color="#0077B5" name="LinkedIn" icon="my-icons:linkedin"></signin-button>

Configuring a custom provider from an object: (as above, but attributes are properties of the object)

<signin-button new-provider="[[providerObject]]"></signin-button>
