Check if a file or directory exists in a given path.
Why? fs.exists
already does the job!
Because fs.exists
and fs.existsSync
will be are deprecated and in some cases we still need them!
fs.exists()
is an anachronism and exists only for historical reasons. There should almost never be a reason to use it in your own code. In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls tofs.exists()
andfs.open()
. Just open the file and handle the error when it's not there.fs.exists()
will be deprecated. <sup>(Source, emphasis added)</sup>

console.log(exists)
// => false
})
// Promises
IsThere.promises.directory(`${__dirname}/contents/dir`).then(exists => {
console.log(exists)
// => true
}).catch(console.error)

:sparkling_heart: Support my projects
I open-source almost everything I can, and I try to reply to everyone needing help using these projects. Obviously, this takes time. You can integrate and use these projects in your applications for free! You can even change the source code and redistribute (even resell it).
However, if you get some profit from this or just want to encourage me to continue creating stuff, there are few ways you can do it:
-
Starring and sharing the projects you like :rocket:
-
—I love books! I will remember you after years if you buy me one. :grin: :book:
-
—You can make one-time donations via PayPal. I'll probably buy a
coffeetea. :tea: -
—Set up a recurring monthly donation and you will get interesting news about what I'm doing (things that I don't share with everyone).
-
Bitcoin—You can send me bitcoins at this address (or scanning the code below):
