React material stepper

Implementation of Material Stepper for React. React material stepper encapsulates logic of step state maintianing, and provides API for control over the step resolution

Features

• Simple, declarative configuration
• Typescript typings
• Horizontal and vertical layouts
• Dynamic steps
• locking
• Default material themes provided
• Customizable by SCSS

Examples

• Simple horizontal stepper (source)
• Simple verical stepper (source)
• Full featured stepper (source)

Getting started

import Stepper, { Step } from "react-material-stepper";

const StepperExample = () => (
  <Stepper>
    <Step
      stepId={STEP1}
      data="Step 1 initial state"
      title="Step One"
      description="This step is optional"
    >
      <Step1 />
    </Step>
    <Step stepId={STEP2} title="Step Two" description="Login is required">
      <Step2 />
    </Step>
    <Step stepId={STEP3} title="Step Three" >
      <Step3 />
    </Step>
  </Stepper>
);

Example1: Basic stepper configuration, where Step1, Step2 and Step3 is arbitary user defined components

In order to work with stepper API StepperContext could be used:

import {
  StepperAction,
  StepperContent,
  StepperContext
} from "react-material-stepper";

export const STEP1 = "step-one";

const Step1 = ({ vertical = false }) => {
  const { resolve, getData } = React.useContext(StepperContext);

  const data = getData(STEP1);

  const onSubmit = (event: React.FormEvent) => {
    event.preventDefault();
    // resolve will set data for current step and proceed to the next step
    resolve("step1 resolved data");
  };

  return (
    <StepperContent
      onSubmit={onSubmit}
      actions={
        <StepperAction align="right" type="submit">
          Continue
        </StepperAction>
      }
    >
      Step1 resolved:
      <pre>{data}</pre>
    </StepperContent>
  );
};

Example2: StepperContext allows step data resolution. Saved data is accessible by getData method

API

Stepper

Prop	Type	Description
initialStep	string | number	Stets initital step by StepId
onResolve	(stepId) => {}	Callback that will be executed on each step resolution
onReject	(stepId) => {}	Callback that will be executed on each step rejection
contextRef	MutableRefObject	Stepper controller reference
className	string	Custom classname will be added to the root stepper container
vertical	boolean	Indicates either horizontal or vertical steppr layout should be used

Step

<Step
  stepId="2"
  title="Step Two"
  loading={isLoading(STEP2)}
  description="Login is required"
>
  ...
</Step>

Example3: Step component describes step configuration

Prop	Type	Description
title*	string	Step title. Required
stepId*	string | number	Unique step identifier. Required
children*	ReactNode	React component that will be rendered when step is activated. Required
description	string	Step description or hint. Optional
loading	boolean	Indicates whether step content is beign loading.
disabled	boolean	Indicates whether step is beign disabled
data	any	Initial state of step
className	string	Custom classname
index	number	Step index

StepperContext

Provides API for control over stepper

Prop	Type	Description
updateStep	(stepId, state) => {}	Updates step state by id.
goAt	stepId => {}	Activates certain step at provided stepId
resolve	data => {}	Resolves current step with provided data
reject	(message, description) => {}	Rejects current step with error and description
isLoading	() => boolean	Indicates whether any of stepper steps is being loading
getCurrentStep	() => StepState	Returns current step state
getStep	stepId => StepState	Returns step state by stepId
getData	(stepId, fallback)	Returns step data, fallback is used when step data is not defined

StepperContent

StepperContent extends form interface, Could be used in custom steps for convenience and styling. Additionally StepperContent accept actions prop, that will be rendered in the footer of stepper content

StepperAction

StepperAction extends button interface, Could be used in custom steps for convenience and styling. Additionally StepperAction accept align ('left' or 'right') prop.

Customization

As part of material theme

$mdc-theme-primary: #fcb8ab;
$mdc-theme-secondary: #feeae6;
$mdc-theme-on-primary: #442b2d;
$mdc-theme-on-secondary: #442b2d;

@import "react-material-stepper/src/index.scss";
@import "material-components-web/material-components-web";

By SCSS variables

$stepper-color-hover: lightblue;
$stepper-color-index: darkblue;
$stepper-color-success: green;
$stepper-color-error: red;
$stepper-color-connector: cornflowerblue;
$stepper-header-height-horizontal: 64px;

@import "react-material-stepper/src/index.scss";

By CSS override

Stepper components allows passing custom className, and use it for override existing styles by applying css rules

import 'react-material-stepper/dist/react-stepper.css';

<Stepper className="custom-theme">
  <Step
    stepId={STEP1}
    title="Step One"
  >
    <Step1 />
  </Step>
  ...
</Stepper>

.stepper.custom-theme {
  background: red;
}
