const fs = require('fs');
const path = require('path');

function getFile() {
    return new Promise((resolve, reject) => {
        const filePath = path.resolve(path.join(__dirname, '../public/images'));
        fs.readdir(filePath, (err, files) => {
            var fileArr = [];
            files.forEach(filename => {
                fileArr.push('/static/images/' + filename);
                resolve(fileArr)
            });
        })   
    });
}

async function getImagesPath() {
    let result = await getFile();
    return result;
}


function insertDbData(){
    getImagesPath().then(res => {
        console.log(res)   
    })
}
insertDbData()
