“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 used to build declarative multi-step journeys (also known as Wizards). You define your step content and ordering and React Albus will manage the journey-related state for you.

React Albus is otherwise unopinionated and allows you to compose functionality such as routing, animation, and analytics however you see fit.

Installation

npm install react-albus

Example

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

const Example = () => (
  <Wizard>
    <Steps>
      <Step
        id="merlin"
        render={({ next }) => (
          <div>
            <h1>Merlin</h1>
            <button onClick={next}>Next</button>
          </div>
        )}
      />
      <Step
        id="gandalf"
        render={({ next, previous }) => (
          <div>
            <h1>Gandalf</h1>
            <button onClick={next}>Next</button>
            <button onClick={previous}>Previous</button>
          </div>
        )}
      />
      <Step
        id="dumbledore"
        render={({ previous }) => (
          <div>
            <h1>Dumbledore</h1>
            <button onClick={previous}>Previous</button>
          </div>
        )}
      />
    </Steps>
  </Wizard>
);

export default Example;

API

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

---

<Wizard>

Props

onNext(wizard): function (optional)

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

preserveSearch: boolean (optional)

Set this to true to preserve search params in the URL.

Params

• wizard (object): The context.wizard object.

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

render(wizard): function (optional)

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

Params

• wizard (object): The context.wizard object.

---

<Steps>

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

Props

step: object (optional)

An object describing the current step with the structure: { id: string }. Defining a step prop will make <Steps> a controlled component.

---

<Step>

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

Props

id: string

Unique key for each step.

In addition to id, any additional props added to <Step> will be available on each step object. This can be used to add names, descriptions, or other metadata to each step.

<WithWizard> is an alias for <Step> that can be used to access context.wizard anywhere within the <Wizard> tree.

---

withWizard()

A higher order component that adds context.wizard as a wizard prop on the wrapped component.

---

context.wizard

<Wizard> provides an object on context with the following properties:

• step (object): Describes the current step with structure: { id: 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(id) (function): Pushes the step with corresponding id onto history.
• replace(id) (function): Replaces the current step in history with the step with corresponding id.

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 <Wizard> with history and basename props.

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;

Build / editing instructions from Common

From Stefan: Run nvm install to get the appropriate version of node, then do an npm install (yarn doesn't work).

Make your changes, then run npm run build to output them to lib/
