exists method for storage/bucket#file ?

[wong2]

Currently I can't find a method to check if a file is already existed in the bucket.

We don't have an exists method (yet/something like it/maybe) but this is what it would do:

file.getMetadata(function(err) {
  if (err.code === 404) {
    // doesn't exist
  }
});

@stephenplusplus thanks! btw I think this should be added to the document or added as a method.

I'm +1 for adding this as a method.....

[stephenplusplus]

The last discussion (#862) ended up (#904) with:

• File.create
• File.get
• File.getOrCreate

Do you want exists in addition to those?

[jgeewax]

I think exists is a super simple shortcut around get -- so yea, I'd be 👍 to adding it to the list.

[stephenplusplus]

exists exists! It will be released this week across all of our APIs (except Datastore for now).

[wong2]

great!
