When using Node, it’s often necessary to know if the path you’re referencing is a file or directory. If you don’t handle these cases, it’s quite easy to call a method that expects one or the other and blows up if it doesn’t get what it wants.
const file = await fs.readFile("/path/to/directory")
To avoid this problem, we can use
lstat on the
These are (nearly) identical:
[fsPromises.lstat() is e]quivalent to fsPromises.stat() unless path refers to a symbolic link, in which case the link itself is stat-ed, not the file that it refers to. Refer to the POSIX lstat(2) document for more detail.
+ const isFile = await fs.lstat('/path/to/directory').isFile() const file = isFile await fs.readFile('/path/to/directory');
