how to write multiple file using recursive function

Question

i wanna write file in one call but i cant looping for creating path.

async function asyncForEach(array, callback) {
for (let index = 0; index < array.length; index++) {
await callback(array[index], index, array);
}
}

to many statment if i using condition to create new file

asyncForEach(items, async (element) => {    
        if(element.hasOwnProperty('item')){
            const path = 'tests/'+element.name;
            console.log(path);
            fs.mkdirSync(path, { recursive: true })
            // await waitFor(50)
            asyncForEach(element.item, async (second) => {
                const second_path = path
                if(second.hasOwnProperty('item') == false){
                    // console.log(second.name)
                    write(second, path, contents)

this is the input JSON

i guess this is what you wan't, to recursively add path when meet dir, write to file when it's leaf node, while not aware of your logic detail, this is a demo code just to clarify how to transform your code to recursive model.

please check ,any more question leave your comment:

    async doFileWriteJob(array, path) {  
    for (let index = 0; index < array.length; index++) {
        element = array[index]
        if(element.hasOwnProperty('item')){
            if(!path) {
                path = 'tests'
            } else {
                path = path + '/' + element.name;
            }
            console.log(path);
            if(element.item && element.item.length > 0) {
                fs.mkdirSync(path, { recursive: true })
                // await waitFor(50)
                doFileWriteJob(element.item, path)
                
            } else {
                if(element.hasOwnProperty('item') == false){
                    // console.log(element.name)
                    write(element, path, element.contents)
                }
            }
        }
    }
})

doFileWriteJob(array, '');

actually i want a read more item property one time then i create new folder and file. pastebin.com/mK68KNHV

Eason Yu Over a year ago

code updated for your code demo. it may not be same to your need, but i think it meets your need to refactor your code to recursive mode.it is: no matter how deep the reference for a function (5 in your example), i just need to show a loop reference in my recursive function,leave some if-else logic to handle the difference in different levels. hope this helps you

Faris dx Over a year ago

to many if else, i need dinamic to write path.
