Storycap Lazy Wait

Helper function to ensure story images have loaded before capturing the story

When storycap captures a story it doesn't know if there is any lazy loading functionality in your application. Luckily storycap provides a waitFor option which can return a promise. The screenshot will not be taken until this promise resolves. This module provides this as a helper functon. It's built with vue-lazyload in mind, but can be expanded to be more configurable in future if required.

Installation

$ yarn add @netsells/storycap-lazy-wait

Usage

Register the storycap addon in your storybook config as outlined in the docs. Then pull in this module and return it in the storybook parameters waitFor option:

import lazyWait from '@netsells/storycap-lazy-wait';

addParameters({
    screenshot: {
        waitFor() {
            return lazyWait();
        },
    },
});

If you already have logic in this method you can return a Promise.all:

addParameters({
    screenshot: {
        waitFor() {
            const myWaitFunctionality = new Promise((resolve) => {
                // ...logic
            })

            return Promise.all([
                myWaitFunctionality,
                lazyWait(),
            ]);
        },
    },
});
