@gavant/ember-button-spinner

A button component built on @gavant/ember-button-basic that accepts an action that returns a promise, and displays a spinner while waiting for the promise to resolve. Also optionally shows a "success" icon if the promise resolves, and "shakes" if the promise rejects.

Compatibility

• Ember.js v3.12 or above
• Ember CLI v2.13 or above
• Node.js v10 or above

Installation

ember install @gavant/ember-button-spinner

To use the addon styles, you must use SASS:

ember install ember-cli-sass

(Upon addon installation, an import statement will be added to your app.scss)

NOTE: This addon uses FontAwesome 5 (@fortawesome/ember-fontawesome) for icon support. However it does NOT install any icon set packages. You must install these separately, following the addon's installation guide, e.g.

yarn add --dev @fortawesome/free-solid-svg-icons

Usage

An example <ButtonSpinner> usage, with all available arguments used. Note that all arguments provided by the base <Button> component are supported too, but are not all listed here. See the addon's usage documentation for details. None of the component arguments are required.

<ButtonSpinner
    @action={{function}}
    @label={{string}}
    @isSpinning={{boolean}}
    @showSuccess={{boolean}}
    @showError={{boolean}}
    @loadingClass={{string}}
    @successClass={{string}}
    @successAnimationClass={{string}}
    @successIcon={{string}}
    @successIconClass={{string}}
/>

{{!-- block form is supported too --}}
<ButtonSpinner @action={{this.someAction}}>
    Look ma, block content!
</Button>

In order for the button to show the spinner animation, the function passed to @action must return a Promise (or be an async function). If the returned promise resolves or rejects with another function, the component will invoke that function as a callback when the button's success or error animation completes. This can be useful in situations where you want to execute some logic after the animation is displayed to the user, such as transitioning to another page. For example:

@action
async saveAndTransition() {
    await this.someAsyncSaveLogic();
    //resolve with a function that will be executed once the success animation finishes
    return () => this.transitionToRoute('somewhere.else');
}

<ButtonSpinner
    @action={{this.saveAndTransition}}
    @label="Transitions after success!"
/>
