Recursively update an observ-struct, only setting values that changed
$ npm install --save soft-update-struct
var softUpdateStruct = require('soft-update-struct')
var Struct = require('observ-struct')
var Observ = require('observ')
var struct = Struct({
foo: Observ(1),
bar: Observ(2),
baz: Observ(3)
})
softUpdateStruct(struct, {
foo: 2,
bar: 2
})
struct() // => {foo: 2, bar: 2, baz: 3}Recursively updates values in struct from data, only calling set on values that have changed.
Required
Type: function
An observable struct.
Type: object
The data to use to update the struct. All keys must have already been defined as observables in the struct. If data is omitted, a partially applied function that takes a data argument will be returned.
Type: function compare (a, b) -> Boolean
By default, changes are detected through an equality-by-reference check (===). Pass in a custom compareFn to change the change detection logic.
