I am new to contentful. I am trying to develop an UI extension on Contentful using Contentful SDK.
I followed all the steps mentioned in this article.
This is the code I have in index.js.
import React from 'react';
import PropTypes from 'prop-types';
import ReactDOM from 'react-dom';
import { TextInput , Button } from '@contentful/forma-36-react-components';
import { init } from 'contentful-ui-extensions-sdk';
import '@contentful/forma-36-react-components/dist/styles.css';
import './index.css';
export class App extends React.Component {
static propTypes = {
sdk: PropTypes.object.isRequired
};
detachExternalChangeHandler = null;
constructor(props) {
super(props);
this.state = {
value: props.sdk.field.getValue() || ''
};
}
componentDidMount() {
this.props.sdk.window.startAutoResizer();
// Handler for external field value changes (e.g. when multiple authors are working on the same entry).
this.detachExternalChangeHandler = this.props.sdk.field.onValueChanged(this.onExternalChange);
}
componentWillUnmount() {
if (this.detachExternalChangeHandler) {
this.detachExternalChangeHandler();
}
}
onExternalChange = value => {
this.setState({ value });
};
onChange = e => {
const value = e.currentTarget.value;
this.setState({ value });
if (value) {
this.props.sdk.field.setValue(value);
} else {
this.props.sdk.field.removeValue();
}
};
onButtonClick = async () => {
console.log('hurray');
};
render() {
return (
<Button buttonType="primary" isFullWidth={false}
onClick={this.onButtonClick}>
Add Content from AEM DAM
</Button>
);
}
}
Ideally i am trying to create an UI extension to be used in contentful space. I downloaded the contentful SDK and i have put in a button. But I receive this error on the console and it doesn't work Screenshot:
