You can provide a custom callback that takes the store object as a parameter instead of using the Lira integrated storing system and dashboard. This allows you to store the message object in your database, so the data never leaves your server.

​
Callback function

The callback function is used to store the message object in your database or any other storage system. The callback function receives the store object as a parameter. The store object is a data structure that holds the input, output, request time, and error of a message. 
{
  input: LiraMessageInputStore;
  output?: LiraMessageOutputStore;
  reqTime?: LiraMessageReqTimesStore;
  error?: unknown;
}
The callback is NOT awaited, to avoid blocking the main thread.

​
Store object

The store object is a data structure that holds the input, output, request time, and error of a message. 
const lira = new Lira({
  store: {
    disabled?: boolean // default: false
    callback: async (data) => {
      console.log(data)
    }
  }
})
​
input
LiraMessageInputStore
required

Pluse the optional provider field that holds the provider that was used to generate the response.
{
  lira?: LiraMetadata
  max_tokens?: number

  model: AnthropicModels | OpenAIModels
  provider?: "Anthropic" | "OpenAI" | string
  temperature?: number
  top_p?: number
  tools?: Array<Tool>
  tool_choice?: ToolChoice
  stop_sequences?: Array<string>
  stream?: boolean
  openai_options?: OpenAIOptions
  anthropic_options?: AnthropicOptions
}
​
output

{
  id?: string
  model?: string
  message: AssistantResponse | ToolUseResponse
  stop_reason?: StopReason
  stop_sequence?: string
  usage?: Usage
  logprobs?: Logprobs

}
​
reqTime
LiraMessageReqTimesStore
