Build powerful chat bots and gateway integrations for Slack, Discord, and other messaging platforms.

​
Quick Start

1

Create a Bot

import { BotConfig, BotProtocol } from 'praisonai';

const config: BotConfig = {
  name: "MyBot",
  token: process.env.BOT_TOKEN,
  prefix: "!",
  channels: ["general", "support"]
};
2

Handle Messages

class MyBot implements BotProtocol {
  name = "MyBot";
  config: BotConfig;
  
  constructor(config: BotConfig) {
    this.config = config;
  }
  
  async connect() {
    console.log("Bot connected!");
  }
  
  async disconnect() {
    console.log("Bot disconnected!");
  }
  
  async sendMessage(channel: string, content: string) {
    // Send message to channel
    return { id: "msg-1", content, ... };
  }
  
  onMessage(handler: (msg: BotMessage) => void) {
    // Register message handler
  }
}

​
Bot Types

​
BotConfig

interface BotConfig {
  name: string;              // Bot name
  token?: string;            // Authentication token
  prefix?: string;           // Command prefix (e.g., "!")
  channels?: string[];       // Allowed channels
  allowedUsers?: string[];   // Allowed user IDs
  metadata?: Record<string, any>;
}

​
BotUser

interface BotUser {
  id: string;                // User ID
  name: string;              // Username
  displayName?: string;      // Display name
  isBot?: boolean;           // Is this a bot?
  metadata?: Record<string, any>;
}

​
BotChannel

interface BotChannel {
  id: string;                // Channel ID
  name: string;              // Channel name
  type: 'text' | 'voice' | 'dm' | 'group';
  metadata?: Record<string, any>;
}

​
BotMessage

interface BotMessage {
  id: string;                // Message ID
  content: string;           // Message content
  author: BotUser;           // Message author
  channel: BotChannel;       // Channel
  timestamp: Date;           // When sent
  attachments?: Array<{
    url: string;
    type: string;
    name?: string;
  }>;
  metadata?: Record<string, any>;
}

​
Bot Protocol

interface BotProtocol {
  name: string;
  config: BotConfig;
  
  connect(): Promise<void>;
  disconnect(): Promise<void>;
  
  sendMessage(channel: string, content: string): Promise<BotMessage>;
  onMessage(handler: (message: BotMessage) => void | Promise<void>): void;
  
  getUser(userId: string): Promise<BotUser | null>;
  getChannel(channelId: string): Promise<BotChannel | null>;
}

​
Gateway Types

​
GatewayConfig

interface GatewayConfig {
  url: string;               // Gateway URL
  apiKey?: string;           // API key
  timeout?: number;          // Request timeout (ms)
  retryAttempts?: number;    // Retry count
  retryDelay?: number;       // Delay between retries (ms)
  metadata?: Record<string, any>;
}

​
GatewayMessage

interface GatewayMessage {
  id: string;
  type: 'request' | 'response' | 'event' | 'error';
  payload: any;
  timestamp: Date;
  correlationId?: string;
  metadata?: Record<string, any>;
}

​
GatewayEvent

interface GatewayEvent {
  type: string;              // Event type
  data: any;                 // Event data
  timestamp: Date;
  source?: string;           // Event source
  metadata?: Record<string, any>;
}

​
Gateway Protocol

interface GatewayProtocol {
  config: GatewayConfig;
  
  connect(): Promise<void>;
  disconnect(): Promise<void>;
  isConnected(): boolean;
  
  send(message: GatewayMessage): Promise<void>;
  receive(): Promise<GatewayMessage | null>;
  
  onEvent(handler: (event: GatewayEvent) => void | Promise<void>): void;
  onError(handler: (error: Error) => void): void;
}

​
Failover Manager

Handle provider failover for high availability: 
import { FailoverManager, FailoverConfig, ProviderStatus } from 'praisonai';

const config: FailoverConfig = {
  providers: ["openai", "anthropic", "google"],
  maxRetries: 3,
  retryDelay: 1000,
  healthCheckInterval: 30000
};

const manager = new FailoverManager(config);

// Get next available provider
const provider = manager.getNextProvider();

// Mark provider as failed
manager.markFailed("openai");

// Check provider status
const status = manager.getStatus("openai");
// Returns: ProviderStatus.HEALTHY | DEGRADED | FAILED

​
Autonomy Levels

import { AutonomyLevel } from 'praisonai';

AutonomyLevel.NONE        // No autonomous actions
AutonomyLevel.LOW         // Minimal autonomy
AutonomyLevel.MEDIUM      // Moderate autonomy
AutonomyLevel.HIGH        // High autonomy
AutonomyLevel.FULL        // Full autonomy

​
Sandbox Types

import { SandboxStatus, SandboxResult, SandboxProtocol } from 'praisonai';

// Sandbox status
SandboxStatus.IDLE
SandboxStatus.RUNNING
SandboxStatus.COMPLETED
SandboxStatus.FAILED
SandboxStatus.TIMEOUT

// Sandbox result
interface SandboxResult {
  status: SandboxStatus;
  output?: string;
  error?: string;
  executionTime?: number;
  metadata?: Record<string, any>;
}

​
Common Patterns

import { BotProtocol, BotConfig, BotMessage, Agent } from 'praisonai';

class SlackBot implements BotProtocol {
  name = "SlackBot";
  config: BotConfig;
  private agent: Agent;
  
  constructor(config: BotConfig) {
    this.config = config;
    this.agent = new Agent({
      name: "SlackAssistant",
      instructions: "Help users in Slack"
    });
  }
  
  onMessage(handler: (msg: BotMessage) => void) {
    // When message received
    this.handleMessage = async (msg) => {
      if (msg.content.startsWith(this.config.prefix!)) {
        const query = msg.content.slice(1);
        const response = await this.agent.start(query);
        await this.sendMessage(msg.channel.id, response);
      }
    };
  }
}

Best Practices

Configure multiple providers with FailoverManager for high availability.
Implement reconnection logic in your bot’s connect() method.
Add rate limiting to prevent overwhelming your agent with messages.
