This example shows how to write an echo telebot for AWS Lambda and how to launch it using Terraform.
|
|
|
|
This bot is different from a typical bot in two ways:
|
|
|
|
1. It is configured with `Settings.Synchronous = true`. This disables asynchronous handlers to let Lambda wait for their completion:
|
|
|
|
```go
|
|
b, _ := tb.NewBot(tb.Settings{Token: token, Synchronous: true})
|
|
```
|
|
|
|
2. Instead of `Settings.Poller` and `bot.Start` it calls `bot.ProcessUpdate` inside `lambda.Start`:
|
|
|
|
```go
|
|
lambda.Start(func(req events.APIGatewayProxyRequest) (err error) {
|
|
var u tb.Update
|
|
if err = json.Unmarshal([]byte(req.Body), &u); err == nil {
|
|
b.ProcessUpdate(u)
|
|
}
|
|
return
|
|
})
|
|
```
|
|
|
|
To launch the bot [install Terraform](https://www.terraform.io/downloads.html), run [`./init.sh`](init.sh) and then [`./deploy.sh`](deploy.sh). To tear down the cloud infrastructure run `terraform destroy`.
