loadData.js

/**
 * loadData.js
 *
 * An utility file adapted from https://github.com/vuejs/blog/blob/master/.vitepress/getPosts.js
 *
 * Main change : reload posts if a change has been detected on a watched directory.
 *
 * The update is triggered by using 'touch' the config.js file
 *
 * Note : this file is located in a `utils` subfolder of the `.vitepress` folder, change the path to conform to your setup.
