You can pass on a few options to the cors wrapper to handle the specific headers you might need. If not tho, we gotchu with some defaults.
- opts.headers: sets up headers that you want browsers to be able to access.
Takes an array. Defaults to
['Content-Type', 'Accept', 'X-Requested-With']
. - opts.methods: these are methods that are allowed to access your resource.
Also takes in an array. Will default to the usual suspects of
['PUT', 'POST', 'DELETE', 'GET', 'OPTIONS']
- opts.credentials: this indicates whether or not a request can be made using credentials. Will default to true.
- opts.origin: this specifies a URI that can access your resource. Takes in
a string and will default to wildcard,
'*'
