Getting Started with AEM Headless Forms App Starter

This project was bootstrapped with Create React App.

This application is built to consume the form model definition of an adaptive form.

System Requirements

• Latest release of GIT

• Node.js 16.13.0 or later

Available Scripts

In the project directory, you can run:

npm install

Install dependencies.

npm start

Runs the app in development mode by proxying the JSON model from an existing API or local filesystem.

After running npm start, your app will be automatically opened in your browser (at path http://localhost:3000). If you make edits, the page will reload.

npm test

Launches the test runner in the interactive watch mode.
See the section about running tests for more information.

npm run build:prod

Builds the app for production to the build folder. It bundles React in production mode and optimizes the build for the best performance. See the section about deployment for more information.

Using external api to fetch form model json

By default, this project is configured to pick the form model json from ../form-definitions/form-model.json. For scenarios where the model needs to be served from an external API, we will need to update the below environment variables in .env file.

• USE_LOCAL_JSON : Set this to 'false'
• FORM_API : Set the value to the HTTP endpoint.

Custom Component.

RichText

Component to render rich text provided in form json.

 {
    ":type": "custom:rich-text",
    "label": {
    "value": "Welcome to <b>Personal Banking</b>"
    }
}

Slider

Instead of using default numeric stepper we can use slider for capturing number value and use :type to use component in Form JSON

Supported Properties

• Maximum
• Minimum
• Step

Example

 {
    ":type": "custom:slider",
    "name": "rateOfInterest",
    "default": 8,
    "maximum": 12,
    "minimum" : 6,
    "fieldType": "number-input",
    "type": "number",
    "label": {
    "value": "Rate of Interest"
    }
}

Mappings Object

A Mappings Object is a JavaScript map that maps the field types defined in the Specification to its respective React Component. The Adaptive Form Super Component uses this map to render the different components defined in the Form JSON.

To use that in your project use the following import, assuming you have added the project as a dependency in your project

import {mappings} from '@aemforms/af-react-components'

Once you have fetched the JSON for the form, the code would look like

import {mappings} from '@aemforms/af-react-components'
const json = {...}
<AdaptiveForm mappings={mappings} formJson={json} />

If you are not using React Spectrum then you might need to start your app with the React Spectrum Provider.

If you are not using Provider at your app level, you can use that with the Adaptive Form Super Component

import {mappings} from '@aemforms/af-react-components'
import { Provider as Spectrum3Provider, defaultTheme } from '@adobe/react-spectrum'
const json = {...}
<SpectrumProvider theme={defaultTheme}>
<AdaptiveForm mappings={mappings} formJson={json} />
</SpectrumProvider>
