About

Demonstrates progress in a multi-step process in your application, such as a payment flow.

• Current step info is denoted by the step store
• If the current step is the last step, the steps component shows as fully complete.

Usage

Install the library

npm i --save-dev @beyonk/svelte-steps

Steps Component

See the example directory for an example.

1. Import the Steps component and the setup function from the library.
2. Configure the Steps component by passing an array of step names and icons
3. Configure the theme option by setting an rgb colour value for the complete theme variable
4. Set the current step by passing it's array index. Usually 0.
5. Add the <Steps> component to your page, and pass it the theme, and the current attributes.

<Steps {theme} />

<script>
	import { Steps, setup, current } from '@beyonk/svelte-steps'
	import { UserIcon, CreditCardIcon, BriefcaseIcon } from 'svelte-feather-icons'
	
	setup([
		{ name: 'About You', icon: UserIcon },
		{ id: 'payment', name: 'Payment', icon: CreditCardIcon }, // id is optional and will be autogenerated
		{ name: 'Confirmation', icon: BriefcaseIcon }
	])
	
	const theme = [
		{ name: 'complete', value: { r: 6, g: 160, b: 146 } }
	]
</script>

Pages Component

The pages component is a mini steps component for pages where space is of the essence.

API

Change Step

To go to a specific step, call to() passing the id of the desired step

<Steps {theme} />

<script>
	import { to } from '@beyonk/svelte-steps'
	
	to('second-step')
</script>

The $step store gives you the ability to implement next and back buttons trivially:

<Steps {theme} />

<button on:click={() => to($step.next)}>Next Step</button>
<button on:click={() => to($step.previous)}>Previous Step</button>

<script>
	import { to, step } from '@beyonk/svelte-steps'
</script>

Add a Step dynamically

After a specified position

To add a new step, pass it to the addStep method:

after is the id of the step which should sit previous to the new step. id is optional, and is the step id. It will be generated in the absence of passing an id

addStep(step, after, id)

<script>
	import { addStep } from '@beyonk/svelte-steps'
	import { StarIcon } from 'svelte-feather-icons'
	
	addStep({ name: 'Thank You!', icon: StarIcon }, 'payment')
</script>

After the current position

To add a new step at the current position, don't pass the position attribute.

addStep(step)

<script>
	import { addStep } from '@beyonk/svelte-steps'
	import { StarIcon } from 'svelte-feather-icons'
	
	addStep({ name: 'New Step', icon: StarIcon })
</script>

With a custom id

To add a new step with an id, pass it as the third param

addStep(step, after, id)

<script>
	import { addStep } from '@beyonk/svelte-steps'
	import { StarIcon } from 'svelte-feather-icons'
	
	addStep({ name: 'New Step', icon: StarIcon }, 'payment', 'foo123')
</script>

Remove a Step dynamically

At a specified position

To add a new step, use the removeStep function, passing the id of the step to remove

removeStep(id)

<script>
	import { removeStep } from '@beyonk/svelte-steps'
	
	removeStep(2)
</script>

Get Presence of Step

To determine if a step exists, query it by id

Step exists? {hasStep('my-step-id')}

<script>
	import { hasStep } from '@beyonk/svelte-steps'
</script>

Step State

The step state import is called step and contains metadata about the steps:

Total Steps: {$step.total}
Current Index: {$step.index}
Current Step Name: {$step.name}
Current Step Id: {$step.id}
Is Last Step? {$step.isLast}
Is First Step? {$step.isFirst}
Next step id: {$step.next} (false if last step)
Previous step id: {$step.previous} (false if first step)

<script>
	import { step } from '@beyonk/svelte-steps'
</script>

Events

The step icons dispatch a step event when clicked, and the event's details.step contains the id and index of the step which was clicked.
