检查typescript中是否存在文件

Question

I am new to typescript and need to check if a certain system is installed on the machine, which is windows. I'm thinking of doing this by checking for the existence of some files, but I'm not finding how to do this check in typescript. Would anyone have any idea how to do it?

Answer 1

fs.stat(path, (exists) => {
            if (exists == null) {
                return true;
            } else if (exists.code === 'ENOENT') {
                return false;
            }
        });

Answer 2

This one works for me

  let file = 'ObjectCreatorBundles'; fs.exists(file, (exist) => { if (exist) { console.log("I got your file") } else { console.log("the file doesn't exists"); } }); 

Answer 3

1. Install file-exists from npm (eg npm install file-exists --save)
2. fileExists('your file name', (err, exists) => console.log(exists))
3. Returns true if filepath exists and is a file

Answer 4

I found this approach much simpler:

import fs from 'fs';
if (fs.existsSync(path)) {
  // File exists in path
} else {
  // File doesn't exist in path
}
