     1  # Nats Source
     2  
     3  The nats source reads config from nats key/values
     4  
     5  ## Nats Format
     6  
     7  The nats source expects keys under the default bucket `default` default key `micro_config`
     8  
     9  Values are expected to be json
    10  
    11  ```
    12  nats kv put default micro_config '{"nats": {"address": "10.0.0.1", "port": 8488}}'
    13  ```
    14  
    15  ```
    16  conf.Get("nats")
    17  ```
    18  
    19  ## New Source
    20  
    21  Specify source with data
    22  
    23  ```go
    24  natsSource := nats.NewSource(
    25  	nats.WithUrl("127.0.0.1:4222"),
    26  	nats.WithBucket("my_bucket"),
    27  	nats.WithKey("my_key"),
    28  )
    29  ```
    30  
    31  ## Load Source
    32  
    33  Load the source into config
    34  
    35  ```go
    36  // Create new config
    37  conf := config.NewConfig()
    38  
    39  // Load nats source
    40  conf.Load(natsSource)
    41  ```
    42  
    43  ## Watch
    44  
    45  ```go
    46  wh, _ := natsSource.Watch()
    47  
    48  for {
    49  	v, err := watcher.Next()
    50  	if err != nil {
    51  		log.Fatalf("err %v", err)
    52  	}
    53  
    54  	log.Infof("data %v", string(v.Data))
    55  }
    56  ```
