TargetableReactComponent

An ECMAScript module containing a React component with JSX to render it.

Presents a convenient API for consumers to add common transforms to React components and the JSX in them, in a semantic way.

Kind: global class

Examples

Code examples for the TargetableReactComponent class.

Modify Venia’s Main component

The TargetableReactComponent class provides functions that change the JSX structure a React component returns. The following example uses some of these functions to make changes to Venia’s Main component. It uses JSX strings found in the main.js file to specify where these changes should happen.

const { Targetables } = require('@magento/pwa-buildpack')

module.exports = targets => {
    const targetables = Targetables.using(targets);

    // Create a TargetableReactComponent linked to the `main.js` file
    const MainComponent = targetables.reactComponent(
        '@magento/venia-ui/lib/components/Main/main.js'
    );

    // Add an import statement for Venia's Button component
    const Button = MainComponent.addImport(
        "Button from '@magento/venia-ui/lib/components/Button'"
    );

    // Use method chaining to call chainable functions one after the other
    MainComponent.appendJSX(
        'div className={pageClass}',
        '<span>appendJSX succeeded!</span>'
    )
        .addJSXClassName('div className={pageClass}', '"newClass"')
        .addJSXClassName('Header', '"anotherClass"')
        .insertAfterJSX(
            '<Footer/>',
            `<${Button} type="button" priority="high">insertAfterJSX succeeded!</${Button}>`
        )
        .insertBeforeJSX(
            '<Header />',
            '<span>insertBeforeJSX succeeded!</span>'
        )
        .replaceJSX('span id={`${dot.path}`}', '<span>replaceJSX worked</span>')
        .prependJSX('div', '<>prependJSX succeeded!</>')
        .removeJSX('span className="busted"')
        .setJSXProps('Footer', {
            'aria-role': '"footer"',
            'data-set-jsx-props-succeeded': true
        })
        .surroundJSX(
            'Header',
            `div style={{ filter: "blur(1px)", outline: "2px dashed red" }}`
        )
        .insertBeforeJSX(
            'Footer aria-role="footer"',
            '<span>Cumulative select worked</span>'
        );
