Full-native implementation of MTProto protocol on Golang!
english русский
All code, from sending requests to encryption serialization is written on pure golang. You don't need to fetch any additional dependencies.
Lib is supports all the API and MTProto features, including video calls and post comments. You can create additional pull request to push api updates!
All changes in TDLib and Android client are monitoring to get the latest features and changes in TL schemas. New methods are creates by adding new lines into TL schema and updating generated code!
No more SQLite databases and caching unnecessary files, that you don't need. Also you can control how sessions are stored, auth process and literally everything that you need!
You can use more than 10 accounts at same time! xelaj/MTProto doesn't create huge overhead in memory or cpu consumption as TDLib. Thanks for that, you can create huge number of connection instances and don't worry about memory overload!
MTProto is really hard in implementation, but it's really easy to use. Basically, this lib sends serialized structures to Telegram servers (just like gRPC, but from Telegram LLC.). It looks like this:
func main() {
client := &Telegram.NewClient()
// for each method there is specific struct for serialization (<method_name>Params{})
result, err := client.MakeRequest(&telegram.GetSomeInfoParams{FromChatId: 12345})
if err != nil {
panic(err)
}
resp, ok := result.(*SomeResponseObject)
if !ok {
panic("Oh no! Wrong type!")
}
}Not so hard, huh? But there is even easier way to send request, which is included in TL API specification:
func main() {
client := &Telegram.NewClient()
resp, err := client.GetSomeInfo(12345)
if err != nil {
panic(err)
}
// resp will be already asserted as described in TL specs of API
// if _, ok := resp.(*SomeResponseObject); !ok {
// panic("No way, we found a bug! Create new issue!")
// }
println(resp.InfoAboutSomething)
}You do not need to think about encryption, key exchange, saving and restoring session, and more routine things. It is already implemented just for you.

Installation is simple. Just do go get:
go get github.com/xelaj/mtprotoAfter that you can generate source structures of methods and functions if you wish to. To do it, use go generate
go generate github.com/xelaj/mtprotoThat's it! You don't need to do anything more!
It's Telegram specific feature. I you want to create client instance and get information about the current servers configuration, you need to do something like this:
resp, err := client.InvokeWithLayer(apiVersion, &telegram.InitConnectionParams{
ApiID: 124100,
DeviceModel: "Unknown",
SystemVersion: "linux/amd64",
AppVersion: "0.1.0",
// just use "en", any other language codes will receive error. See telegram docs for more info.
SystemLangCode: "en",
LangCode: "en",
// HelpGetConfig() is ACTUAL request, but wrapped in IvokeWithLayer
Query: &telegram.HelpGetConfigParams{},
})Why? We don't know! This method is described in Telegram API docs, any other starting requests will receive error.
Example here
func AuthByPhone() {
resp, err := client.AuthSendCode(
yourPhone,
appID,
appHash,
&telegram.CodeSettings{},
)
if err != nil {
panic(err)
}
// You can make any way to enter verification code, like in
// http requests, or what you like. You just need to call two
// requests, that's main method.
fmt.Print("Auth code:")
code, _ := bufio.NewReader(os.Stdin).ReadString('\n')
code = strings.Replace(code, "\n", "", -1)
// this is ALL process of authorization! :)
fmt.Println(client.AuthSignIn(yourPhone, resp.PhoneCodeHash, code))
}That's it! You don't need any cycles, code is ready-to-go for async execution. You just need to follow the official Telegram API documentation.
There is a pretty huge chunk of documentation. We are ready to describe every method and object, but its requires a lot of work. Although all methods are already described here.
Technically — yes. In practice — components don't require specific architecture, but we didn't test it yet. If you have any problems running it, just create an issue, we will try to help.
Please read contributing guide if you want to help. And the help is very necessary!
