Upgrade from 4.x to 5.0.0

Previously, the promiseTypeSeparator config property was used to change the character used to join type strings.

Now, the promiseTypeDelimiter config property is used. Why? Because delimiters are one or more characters used to specify the boundaries in strings. It’s s delimiter, not a separator!

applyMiddleware(
  promiseMiddleware({
    promiseTypeDelimiter: '/'
  })
)

With this configuration, given FOO async action, the type will be appended with a forward slash / delimiter.

{
  type: 'FOO/PENDING'
}
