Mirror and optionally transform data from one sublevel into another.
Mirror the posts collection to the
home sublevel and only include
slug there, because the homepage doesn't display a post's content.
var level = ;var sub = ;var mirror = ;var db =;// pass a function;// OR an array of properties;var id = '1337';db;
From the point you call
mirror on, all operations performed on sublevel
will be mirrored onto sublevel
If you pass in
transform, the changes' values will be transformed on
the fly by the function. It receives the current value and is expected to
return the potentially modified value. If it returns
undefined, the change
will be dropped.
transform can also be an array, in which case it limits values to the keys
contained in it.
With npm do:
npm install level-mirror
