Health is a library used for creating a very simple health endpoint.
|
|
|
|
While implementing a health endpoint is very simple, I've grown tired of implementing
|
|
it over and over again.
|
|
|
|
|
|
## Installation
|
|
```
|
|
go get -u github.com/TwiN/health
|
|
```
|
|
|
|
|
|
## Usage
|
|
To retrieve the handler, you must use `health.Handler()` and are expected to pass it to the router like so:
|
|
```go
|
|
router := http.NewServeMux()
|
|
router.Handle("/health", health.Handler())
|
|
server := &http.Server{
|
|
Addr: ":8080",
|
|
Handler: router,
|
|
}
|
|
```
|
|
|
|
By default, the handler will return `UP` when the status is down, and `DOWN` when the status is down.
|
|
If you prefer using JSON, however, you may initialize the health handler like so:
|
|
```go
|
|
router.Handle("/health", health.Handler().WithJSON(true))
|
|
```
|
|
The above will cause the response body to become `{"status":"UP"}` and `{"status":"DOWN"}` for both status respectively.
|
|
|
|
To change the health of the application, you can use `health.SetStatus(<status>)` where `<status>` is one `health.Up`
|
|
or `health.Down`:
|
|
|
|
```go
|
|
health.SetStatus(health.Up)
|
|
health.SetStatus(health.Down)
|
|
```
|
|
|
|
|
|
### Complete example
|
|
```go
|
|
package main
|
|
|
|
import (
|
|
"net/http"
|
|
"time"
|
|
|
|
"github.com/TwiN/health"
|
|
)
|
|
|
|
func main() {
|
|
router := http.NewServeMux()
|
|
router.Handle("/health", health.Handler())
|
|
server := &http.Server{
|
|
Addr: "0.0.0.0:8080",
|
|
Handler: router,
|
|
ReadTimeout: 15 * time.Second,
|
|
WriteTimeout: 15 * time.Second,
|
|
IdleTimeout: 15 * time.Second,
|
|
}
|
|
server.ListenAndServe()
|
|
}
|
|
```
