I need to check if a file exists in a gulp task, i know i can use some node functions from node, there are two:
fs.exists() and fs.existsSync()
The problem is that in the node documentation, is saying that these functions will be deprecated
You can use fs.access
fs.access('/etc/passwd', (err) => {
if (err) {
// file/path is not visible to the calling process
console.log(err.message);
console.log(err.code);
}
});
List of available error codes here
Using
fs.access()to check for the accessibility of a file before callingfs.open(), fs.readFile()orfs.writeFile()is not recommended. Doing so introduces a race condition, since other processes may change the file's state between the two calls. Instead, user code should open/read/write the file directly and handle the error raised if the file is not accessible.
