Faster JSON serialization for Golang

SuperCereal is a simple and efficient JSON serialization library for Go. Unlike most other serializers, including Go's json.Marshal and JavaScript's JSON.stringify, it doesn't operate using an intermediary tree data structure. This makes it significantly more efficient in both time and memory. Because it doesn't use third-party non-standard preprocessing, your code remains purely standard & portable Golang.

17x the json.Marshal performance

supercereal.Marshal(func(object *supercereal.Object) {
  object.Put("firstName", "John")
  object.Put("lastName", "Smith")
  object.Put("isAlive", true)
  object.Put("age", 25)
  object.Put("address", func(object *supercereal.Object) {
    object.Put("streetAddress", "21 2nd Street")
    object.Put("city", "New York")
    object.Put("state", "NY")
    object.Put("postalCode", "10021-3100")
  })
  object.Put("phoneNumbers", func(array *supercereal.Array) {
    array.Put(func(object *supercereal.Object) {
      object.Put("type", "home")
      object.Put("number", "212 555-1234")
    })
    array.Put(func(object *supercereal.Object) {
      object.Put("type", "office")
      object.Put("number", "646 555-4567")
    })
    array.Put(func(object *supercereal.Object) {
      object.Put("type", "mobile")
      object.Put("number", "123 456-7890")
    })
  })
  object.Put("children", func(array *supercereal.Array) {})
  object.Put("spouse", nil)
})

Where supercereal.Marshal returns the []byte (here prettified for demonstration):

{
  "firstName": "John",
  "lastName": "Smith",
  "isAlive": true,
  "age": 25,
  "address": {
    "streetAddress": "21 2nd Street",
    "city": "New York",
    "state": "NY",
    "postalCode": "10021-3100"
  },
  "phoneNumbers": [
    {
      "type": "home",
      "number": "212 555-1234"
    },
    {
      "type": "office",
      "number": "646 555-4567"
    },
    {
      "type": "mobile",
      "number": "123 456-7890"
    }
  ],
  "children": [],
  "spouse": null
}
