# jsonstore :convenience_store:
[](https://godoc.org/github.com/schollz/jsonstore)
*JSONStore* is a Go-library for a simple thread-safe in-memory JSON key-store with persistent backend. It's made for those times where you don't need a RDBMS like [MySQL](https://www.mysql.com/), or a NoSQL like [MongoDB](https://www.mongodb.com/) - basically when you just need a simple keystore. A really simple keystore. *JSONStore* is used in those times you don't need a distributed keystore like [etcd](https://coreos.com/etcd/docs/latest/), or
a remote keystore [Redis](https://redis.io/) or a local keystore like [Bolt](https://github.com/boltdb/bolt). Its really for those times where you just need a JSON file.
## Usage
First, install the library using:
```
go get -u -v github.com/schollz/jsonstore
```
Then you can add it to your program. Check out the examples, or see below for basic usage:
```golang
ks := new(jsonstore.JSONStore)
// set a key to any object you want
type Human struct {
Name string
Height float64
}
err := ks.Set("human:1", Human{"Dante", 5.4})
if err != nil {
panic(err)
}
// Saving will automatically gzip if .gz is provided
if err = jsonstore.Save(ks, "humans.json.gz"); err != nil {
panic(err)
}
// Load any JSON / GZipped JSON
ks2, err := jsonstore.Open("humans.json.gz")
if err != nil {
panic(err)
}
// get the data back via an interface
var human Human
err = ks2.Get("human:1", &human)
if err != nil {
panic(err)
}
fmt.Println(human.Name) // Prints 'Dante'
```
The datastore on disk is then contains:
```bash
$ zcat humans.json.gz
{
"human:1": "{\"Name\":\"Dante\",\"Height\":5.4}"
}
```

# Dev
Benchmark against using Redis and BoltDB as KeyStores using Go1.8 (Intel i5-4310U CPU @ 2.00GHz). Take away is that setting/getting is faster in *JSONStore* (because its just a map), but opening is much slower (because its a file that is read into memory). So don't use this if you have to store 1,000,000+ things!
```
$ go test -bench=. tests/redis/* > redis.txt
$ go test -bench=. tests/bolt/* > bolt.txt
$ go test -bench=. > jsonstore.txt
