# Go-ReJSON - a golang client for ReJSON (a JSON data type for Redis)
Go-ReJSON is a [Go](https://golang.org/) client for [ReJSON](https://github.com/RedisLabsModules/rejson) Redis Module.

> ReJSON is a Redis module that implements ECMA-404 The JSON Data Interchange Standard as a native data type. It allows storing, updating and fetching JSON values from Redis keys (documents).
Primary features of ReJSON Module:
* Full support of the JSON standard
* JSONPath-like syntax for selecting element inside documents
* Documents are stored as binary data in a tree structure, allowing fast access to sub-elements
* Typed atomic operations for all JSON values types
Each and every feature of ReJSON Module is fully incorporated in the project.
Enjoy ReJSON with the type-safe Redis client, [`Go-Redis/Redis`](https://github.com/go-redis/redis) or use the
print-like Redis-api client [`GoModule/Redigo`](https://github.com/gomodule/redigo). Go-ReJSON supports both the
clients. Use any of the above two client you want, Go-ReJSON helps you out with all its features and functionalities in
a more generic and standard way.
Support for `mediocregopher/radix` and other Redis clients is in our RoadMap. Any contributions to the support for other
clients is hearty welcome.
## Installation
go get github.com/nitishm/go-rejson/v4
## Example usage
```golang
package main
import (
"context"
"encoding/json"
"flag"
"fmt"
"log"
"github.com/nitishm/go-rejson/v4"
goredis "github.com/go-redis/redis/v8"
"github.com/gomodule/redigo/redis"
)
// Name - student name
type Name struct {
First string `json:"first,omitempty"`
Middle string `json:"middle,omitempty"`
Last string `json:"last,omitempty"`
}
// Student - student object
type Student struct {
Name Name `json:"name,omitempty"`
Rank int `json:"rank,omitempty"`
}
