How can you create multiple directories with paths received in response from from api call?

Question

I am receiving a list of objects from the front-end and i want to create multiple directories from the values stored in that key value pairs. So far I tried this method but it isn't working.

filercv=layerorder.map(layer=>{
    return `layers/${layer.name}`;
  })
  console.log(filercv)

var count 
function makeAllDirs(root, list) {

    return list.reduce((p, item) => {
        return p.then(() => {
          console.log(item)
          console.log(root)
          
            return mkdirp(path.join(root,item));
        });
    }, Promise.resolve());
}

// usage



makeAllDirs(basePath,filercv).then(() => {
   console.log('yes')
}).catch(err => {
   // error here
   console.log(err)
});
};
//layerorder
layerorder=[{"name":"bodies"},{"name":"Top"}]

But when i run this code only one folder is created in the layers directory i.e bodies.

check within mkdirp(), maybe your path resolves to somewhere else, so check the final constructed path, or maybe the recursive flag is missing: fs.mkdir(path)

Also, try async/await, this will create folders in process.cwd():

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


function mkdirp(dir) {
    return new Promise((resolve, reject) => {
        console.log('--creating dir: ', path.resolve(dir));
        fs.mkdir(dir, {
            recursive: true
        }, (err) => {
            if (err) reject(err);
            resolve();
        });
    });
}


//layerorder
const layerorder = [{
    "name": "bodies"
}, {
    "name": "Top"
}];

const filercv = layerorder.map(layer => {
    return `layers/${layer.name}`;
});

console.log('dirs: ', filercv);

// check path
let basePath = process.cwd();

async function makeAllDirs() {
    try {
        await Promise.all(filercv.map(dir => {
            console.log(`root: ${basePath}, item: ${dir}`);
            return mkdirp(path.join(basePath, dir))
        }));
        console.log('yes');
    } catch (err) {
        console.log('no', err);
    }
}

makeAllDirs();
