Class Method Details

.literals ⇒ Object

If the env var is set then we pre-load all the reserved literals into a big array. This makes checking for reserved subdomains quicker but at the expense of keeping the big array in memory.

If you’re only checking for reserved subdomains when a user creates a new account then it may be better to load the literals from the file each time.
