node.js - node如何判断文件夹是否存在呢？

Question

console.log(fs.statSync('./_test/'));
如果_test不存在，会报错。并没有返回值，那么如何判断文件夹是否存在呢？

忘记说了我是node6, fs.exists这个文档已经明确指出 废弃了

Answer 1

fs.exists is deprecated, it is recommended to use fs.stat and fs.access. The following is what I use in my project:

//检测文件或者文件夹存在 nodeJS
function fsExistsSync(path) {
    try{
        fs.accessSync(path,fs.F_OK);
    }catch(e){
        return false;
    }
    return true;
}

Of course, this is only the synchronous version. If you need an asynchronous version, you can modify it yourself~ If it is useful, please update it below your question so that future generations can view it.

Answer 3

Use where node

Answer 4

I remember that there is fs.exists and fs.existsSync, both of which can determine whether it exists. The latter one is synchronous
