node-webpack-merge - 2.2.0-4 main

webpack-merge provides a merge function
that concatenates arrays and merges objects
creating a new object.
If functions are encountered,
it will execute them, run the results through the algorithm,
and then wrap the returned values within a function again.
.
This behavior is particularly useful in configuring webpack
although it has uses beyond it.
Whenever you need to merge configuration objects,
webpack-merge can come in handy.
.
There's also a webpack specific merge variant
known as merge.smart
that's able to take webpack specifics into account
(i.e., it can flatten loader definitions).
