React Albus

“Let us <Step> into the night and pursue that flighty temptress, adventure.”

-- Albus Dumbledore

What is React Albus?

React Albus is a React component library for building declarative multi-step flows (also known as Wizards). You are responsible for writing your own steps and configuring their ordering, but React Albus will maintain the flow-related state for you.

React Albus also allows you to create routed flows, conditionally skip steps in your flow, and create custom elements to suit your needs.

Example

import React from 'react';
import { Wizard, Step, Steps, Navigation } from 'react-albus';

const Simple = () =>
  <Wizard>
    <Steps>
      <Step path="firstStep">
        <h1>First Step</h1>
        <Navigation
          render={({ next }) =>
            <button onClick={next}>Next</button>}
        />
      </Step>
      <Step path="secondStep">
        <h1>Second Step</h1>
        <Navigation
          render={({ next, previous }) =>
            <div>
              <button onClick={next}>Next</button>
              <button onClick={previous}>Previous</button>
            </div>}
        />
      </Step>
      <Step path="thirdStep">
        <h1>Third Step</h1>
        <Navigation
          render={({ previous }) =>
            <button onClick={previous}>Previous</button>}
        />
      </Step>
    </Steps>
  </Wizard>;

export default Simple;

API

• <Wizard>
• <Step>
• <Steps>
• <Navigation>
• withWizard
• context.wizard

<Wizard>

Props

onNext(step, steps, push): function (optional)

A function that will be called by Wizard to determine the next step to proceed to.

Params

• step: An object describing the current step with the signature: { path: string, name: string }.
• steps: An array of step objects in the order they were declared in <Steps>.
• push(path): A function that can be called with the path of the step that you want to proceed to. Calling this function without arguments will proceed to the next step.

If you do not pass an onNext prop, <Wizard> will proceed directly to the next step.

className: string (optional)

CSS classes to be added to the <div> created by <Wizard>.

render(wizard): function (optional)

A function that will be used as the render function of <Wizard>.

Params

• wizard: The context.wizard object.

<Step>

Wraps all the content that will be conditionally shown when the step is active.

Props

path: string

Unique key for each step.

name: string (optional)

A name for the step that can later be accessed on context.wizard.

className: string (optional)

CSS classes to be added to the <div> created by <Step>.

<Steps>

Wraps all of the <Step> components for your flow. The only direct children of <Steps> should be <Step> components.

Props

step: object (optional)

An object describing the current step with the signature: { path: string, name: string }. Defining this prop will make <Steps> a controlled component.

<Navigation>

Exposes the Wizard navigation functionality for your components to use. Extends its child's props with context.wizard and passes context.wizard to its render prop.

Props

render(wizard): function (optional)

A function that will be used as the render function of <Navigation>.

Params

• wizard: The context.wizard object.

withWizard()

A higher order component that spreads context.wizard across the wrapped component's props.

context.wizard

<Wizard> adds this object to context with the following properties:

• step (object): Describes the current step with signature: { path: string, name: string }.
• steps (array): Array of step objects in the order they were declared within <Steps>.
• history (object): The backing history object.
• next() (function): Moves to the next step in order.
• previous() (function): Moves to the previous step in order.
• go(n) (function): Moves n steps in history.
• push(path) (function): Moves to the step with prop path.

Usage with React Router

Internally, React Albus uses history to maintain the ordering of steps. This makes integrating with React Router (or any other router) as easy as providing Albus with a history object and a basename where it is living.

import React from 'react';
import { Route } from 'react-router-dom';
import { Wizard } from 'react-albus';

const RoutedWizard = ({ children }) =>
  <Route
    render={({ history, match: { url } }) =>
      <Wizard history={history} basename={url}>
        {children}
      </Wizard>}
  />;

export default RoutedWizard;
