toJS

toJS(value, options?)

Recursively converts an (observable) object to a javascript structure. Supports observable arrays, objects, maps and primitives. Computed values and other non-enumerable properties won't be part of the result. Cycles are detected and properly supported by default, but this can be disabled to improve performance.

toJS accepts three options

1. exportMapsAsObjects whether to serialize observable maps to objects (true) or javascript Map objects (false) default true.
2. detectCycles if a cycle is detected, reuse the already serialized object. Which prevents endless recursion. Default true.
3. recurseEverything detects and converts observable objects that are "behind" non-observable objects.

For more complex (de)serialization scenario's, one can use serializr

var obj = mobx.observable({
    x: 1,
})

var clone = mobx.toJS(obj)

console.log(mobx.isObservableObject(obj)) // true
console.log(mobx.isObservableObject(clone)) // false

Note: this method was named toJSON before MobX 2.2
