Always benchmark with your own workload.
|
|
The result depends heavily on the data input.

# Usage
|
|
|
|
100% compatibility with standard lib
|
|
|
|
Replace
|
|
|
|
```go
|
|
import "encoding/json"
|
|
json.Marshal(&data)
|
|
```
|
|
|
|
with
|
|
|
|
```go
|
|
import jsoniter "github.com/json-iterator/go"
|
|
|
|
var json = jsoniter.ConfigCompatibleWithStandardLibrary
|
|
json.Marshal(&data)
|
|
```
|
|
|
|
Replace
|
|
|
|
```go
|
|
import "encoding/json"
|
|
json.Unmarshal(input, &data)
|
|
```
|
|
|
|
with
|
|
|
|
```go
|
|
import jsoniter "github.com/json-iterator/go"
|
|
|
|
var json = jsoniter.ConfigCompatibleWithStandardLibrary
|
|
json.Unmarshal(input, &data)
|
|
```
