isn't there an asynchronous call inside foreach? resolve is definitely not allowed outside
since I know how to use await/async and promise, why use a bunch of callback? this is my own test. Available, you can take a look at
const fs = require('fs');
const path = require('path');
const { promisify } = require('util');
const readdir = promisify(fs.readdir);
const stat = promisify(fs.stat);
let imgPathArr = [];
async function loopFile(folder) {
let files = await readdir(folder);
for(let i=0; i<files.length; iPP) {
let file = await stat(path.join(folder, files[i]));
if(file.isFile()) {
imgPathArr.push(path.join(folder, files[i]));
}else{
await loopFile(path.join(folder, files[i]));
}
}
}
(async () => {
await loopFile(path.join(__dirname, 'files'));
console.log(imgPathArr);
)();loop. It is recommended to use the for loop
this is not a code problem. It's your nodemon observation file that changes. You try to shut down nodemon first.
