# GZIP gin's middleware
[](https://github.com/gin-contrib/gzip/actions/workflows/go.yml)
[](https://codecov.io/gh/gin-contrib/gzip)
[](https://goreportcard.com/report/github.com/gin-contrib/gzip)
[](https://godoc.org/github.com/gin-contrib/gzip)
Gin middleware to enable `GZIP` support.
## Usage
Download and install it:
```sh
go get github.com/gin-contrib/gzip
```
Import it in your code:
```go
import "github.com/gin-contrib/gzip"
```
Canonical example:
```go
package main
import (
"fmt"
"net/http"
"time"
"github.com/gin-contrib/gzip"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
r.Use(gzip.Gzip(gzip.DefaultCompression))
r.GET("/ping", func(c *gin.Context) {
c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Listen and Server in 0.0.0.0:8080
if err := r.Run(":8080"); err != nil {
log.Fatal(err)
}
}
```
### Customized Excluded Extensions
```go
package main
import (
"fmt"
"net/http"
"time"
"github.com/gin-contrib/gzip"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
r.Use(gzip.Gzip(gzip.DefaultCompression, gzip.WithExcludedExtensions([]string{".pdf", ".mp4"})))
r.GET("/ping", func(c *gin.Context) {
c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Listen and Server in 0.0.0.0:8080
if err := r.Run(":8080"); err != nil {
log.Fatal(err)
}
}
```
### Customized Excluded Paths
```go
package main
import (
"fmt"
"net/http"
"time"
"github.com/gin-contrib/gzip"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
r.Use(gzip.Gzip(gzip.DefaultCompression, gzip.WithExcludedPaths([]string{"/api/"})))
r.GET("/ping", func(c *gin.Context) {
c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Listen and Server in 0.0.0.0:8080
if err := r.Run(":8080"); err != nil {
log.Fatal(err)
}
}
```
### Customized Excluded Paths with Regex
```go
package main
import (
"fmt"
"net/http"
"time"
"github.com/gin-contrib/gzip"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
r.Use(gzip.Gzip(gzip.DefaultCompression, gzip.WithExcludedPathsRegexs([]string{".*"})))
r.GET("/ping", func(c *gin.Context) {
c.String(http.StatusOK, "pong "+fmt.Sprint(time.Now().Unix()))
})
// Listen and Server in 0.0.0.0:8080
if err := r.Run(":8080"); err != nil {
log.Fatal(err)
}
}
```
### Server Push
```go
package main
import (
"fmt"
"log"
"net/http"
"time"
"github.com/gin-contrib/gzip"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
r.Use(gzip.Gzip(gzip.DefaultCompression))
r.GET("/stream", func(c *gin.Context) {
c.Header("Content-Type", "text/event-stream")
c.Header("Connection", "keep-alive")
for i := 0; i < 10; i++ {
fmt.Fprintf(c.Writer, "id: %d\ndata: tick %d\n\n", i, time.Now().Unix())
c.Writer.Flush()
time.Sleep(1 * time.Second)
}
})
// Listen and Server in 0.0.0.0:8080
if err := r.Run(":8080"); err != nil {
log.Fatal(err)
}
}
```
