WhizFlow
WhizFlow is a lightweight, headless and extensible React library for building dynamic multi-step forms or troubleshooting workflows.
Features
- Headless: Gives you full control over the UI and styling.
- Extensible: Allows custom question types and render implementations.
- Flexible: Easily build complex workflows with conditional branching.
- Agnostic: Use Formik or any other form/validation library that you want to handle the input.
Demo
Installation
npm install whizflow
or
yarn add whizflow
Usage
- Import WhizFlow and required types:
import WhizFlow from 'whizflow';
import { Step } from 'whizflow/dist/types';
- Define your workflow:
const workflow: Step[] = [
{
id: 'step1',
questions: [
{
id: 'question1',
prompt: 'What is your name?',
inputType: 'text',
},
],
next: (answers) => 'step2',
},
{
id: 'step2',
questions: [
{
id: 'question2',
prompt: 'What is your favorite color?',
inputType: 'text',
},
],
next: (answers) => 'done',
},
];
- Define your custom question types (optional):
const questionTypes = {
text: (question, answers, setAnswers) => (
<div key={question.id}>
<label htmlFor={question.id}>{question.prompt}</label>
<input
id={question.id}
type="text"
value={answers[question.id] || ''}
onChange={(e) =>
setAnswers({ ...answers, [question.id]: e.target.value })
}
/>
</div>
),
// Add more question types and their render functions here
};
- Use the WhizFlow component in your application:
const YourComponent = () => {
return (
<WhizFlow workflow={workflow} questionTypes={questionTypes}>
{({ step, answers, setAnswers, handleNext, renderQuestion }) => (
<div>
{step.questions.map((question) => renderQuestion(question.id))}
<button onClick={handleNext}>Next</button>
</div>
)}
</WhizFlow>
);
};
export default YourComponent;
Types
WhizFlow
WhizFlow
is the main component for managing the workflow. It accepts the following props:
Props
workflow
(required): An array ofStep
objects defining the workflow.onComplete
(optional): A callback function to be called when the workflow reaches thedone
step.questionTypes
(optional): An object with keys representing the question type and values as the corresponding render functions.
Render Props
step
: The current step object.answers
: An object containing the answers for each question in the workflow.loading
: A boolean to mark whenhandleNext
is waiting to resolve.setAnswers
: A function to update theanswers
object.handleNext
: A function to handle navigation to the next step in the workflow.handlePrev
: A function to handle navigation to the previous step.renderQuestion
: A function to render the correct question type based on the provided dictionary.
Step
A Step
object defines a single step in the workflow and includes the following properties:
id
: A unique identifier for the step.questions
: An array ofQuestion
objects.next
: A function that determines the next step in the workflow based on the current answers. It should return the next step's ID ordone
if the workflow is complete.
Question
A Question
object defines a single question within a step and includes the following properties:
id
: A unique identifier for the question.prompt
: The question's text.inputType
: The question's input type, which corresponds to the key in thequestionTypes
prop passed to theWhizFlow
component.
QuestionTypes
An object with keys representing the question type and values as render functions. The render functions should take the question, answers, and a setAnswers
function as arguments and return a React element. You can define custom question types and their implementations in the questionTypes
object.
const questionTypes = {
text: (question, answers, setAnswers) => (
<div key={question.id}>
<label htmlFor={question.id}>{question.prompt}</label>
<input
id={question.id}
type="text"
value={answers[question.id] || ''}
onChange={(e) =>
setAnswers({ ...answers, [question.id]: e.target.value })
}
/>
</div>
),
// Add more question types and their render functions here
};
