# Redeo
[](https://pkg.go.dev/github.com/bsm/redeo/v2)
[](https://opensource.org/licenses/Apache-2.0)
The high-performance Swiss Army Knife for building redis-protocol compatible servers/services.
## Parts
This repository is organised into multiple components:
* [root](./) package contains the framework for building redis-protocol compatible,
high-performance servers.
* [resp](./resp/) implements low-level primitives for dealing with
RESP (REdis Serialization Protocol), client and server-side. It
contains basic wrappers for readers and writers to read/write requests and
responses.
* [client](./client/) contains a minimalist pooled client.
For full documentation and examples, please see the individual packages and the
official API documentation: https://godoc.org/github.com/bsm/redeo.
## Examples
A simple server example with two commands:
```go
package main
import (
"net"
"github.com/bsm/redeo/v2"
)
func main() {
srv := redeo.NewServer(nil)
// Define handlers
srv.HandleFunc("ping", func(w resp.ResponseWriter, _ *resp.Command) {
w.AppendInlineString("PONG")
})
srv.HandleFunc("info", func(w resp.ResponseWriter, _ *resp.Command) {
w.AppendBulkString(srv.Info().String())
})
// More handlers; demo usage of redeo.WrapperFunc
srv.Handle("echo", redeo.WrapperFunc(func(c *resp.Command) interface{} {
if c.ArgN() != 1 {
return redeo.ErrWrongNumberOfArgs(c.Name)
}
return c.Arg(0)
}))
// Open a new listener
lis, err := net.Listen("tcp", ":9736")
if err != nil {
panic(err)
}
defer lis.Close()
// Start serving (blocking)
srv.Serve(lis)
}
```
More complex handlers:
```go
func main() {
mu := sync.RWMutex{}
data := make(map[string]string)
srv := redeo.NewServer(nil)
srv.HandleFunc("set", func(w resp.ResponseWriter, c *resp.Command) {
if c.ArgN() != 2 {
w.AppendError(redeo.WrongNumberOfArgs(c.Name))
return
}
key := c.Arg(0).String()
val := c.Arg(1).String()
mu.Lock()
data[key] = val
mu.Unlock()
w.AppendInt(1)
})
srv.HandleFunc("get", func(w resp.ResponseWriter, c *resp.Command) {
if c.ArgN() != 1 {
w.AppendError(redeo.WrongNumberOfArgs(c.Name))
return
}
key := c.Arg(0).String()
mu.RLock()
val, ok := data[key]
mu.RUnlock()
if ok {
w.AppendBulkString(val)
return
}
w.AppendNil()
})
}
```
Redeo also supports command wrappers:
```go
func main() {
mu := sync.RWMutex{}
data := make(map[string]string)
srv := redeo.NewServer(nil)
srv.Handle("set", redeo.WrapperFunc(func(c *resp.Command) interface{} {
if c.ArgN() != 2 {
return redeo.ErrWrongNumberOfArgs(c.Name)
}
key := c.Arg(0).String()
val := c.Arg(1).String()
mu.Lock()
data[key] = val
mu.Unlock()
return 1
}))
srv.Handle("get", redeo.WrapperFunc(func(c *resp.Command) interface{} {
if c.ArgN() != 1 {
return redeo.ErrWrongNumberOfArgs(c.Name)
}
key := c.Arg(0).String()
mu.RLock()
val, ok := data[key]
mu.RUnlock()
if ok {
return val
}
return nil
}))
}
```
