Explore the Playground — it's like Trello or Asana, but for AI Agents and humans.
npm install kaibanjs// Using ES6 import syntax for NextJS, React, etc.
import { Agent, Task, Team } from 'kaibanjs';// Using CommonJS syntax for NodeJS
const { Agent, Task, Team } = require("kaibanjs");Note: KaibanJS is TypeScript-supported. To learn more, check out the NodeJS TypeScript example.
In this example, we use KaibanJS to build a resume generation team. If you're looking to create or update your resume, this setup utilizes specialized AI agents to automatically process your information and produce a polished, professional resume tailored to your career goals.
// Define agents with specific roles and goals
const profileAnalyst = new Agent({
name: 'Mary',
role: 'Profile Analyst',
goal: 'Extract structured information from conversational user input.',
background: 'Data Processor',
tools: [] // Tools are omitted for now
});
const resumeWriter = new Agent({
name: 'Alex Mercer',
role: 'Resume Writer',
goal: `Craft compelling, well-structured resumes
that effectively showcase job seekers qualifications and achievements.`,
background: `Extensive experience in recruiting,
copywriting, and human resources, enabling
effective resume design that stands out to employers.`,
tools: []
});
// Define the tasks for each agent
const processingTask = new Task({
description: `Extract relevant details such as name,
experience, skills, and job history from the user's 'aboutMe' input.
aboutMe: {aboutMe}`,
expectedOutput: 'Structured data ready to be used for a resume creation.',
agent: profileAnalyst
});
const resumeCreationTask = new Task({
description: `Utilize the structured data to create
a detailed and attractive resume.
Enrich the resume content by inferring additional details from the provided information.
Include sections such as a personal summary, detailed work experience, skills, and educational background.`,
expectedOutput: `A professionally formatted resume in markdown format,
ready for submission to potential employers.`,
agent: resumeWriter
});
// Create and start the team
const team = new Team({
name: 'Resume Creation Team',
agents: [profileAnalyst, resumeWriter],
tasks: [processingTask, resumeCreationTask],
inputs: { aboutMe: `My name is David Llaca.
JavaScript Developer for 5 years.
I worked for three years at Disney,
where I developed user interfaces for their primary landing pages
using React, NextJS, and Redux. Before Disney,
I was a Junior Front-End Developer at American Airlines,
where I worked with Vue and Tailwind.
I earned a Bachelor of Science in Computer Science from FIU in 2018,
and I completed a JavaScript bootcamp that same year.` }, // Initial input for the first task
env: {OPENAI_API_KEY: 'your-open-ai-api-key'} // Environment variables for the team
});
// Listen to the workflow status changes
// team.onWorkflowStatusChange((status) => {
// console.log("Workflow status:", status);
// });
team.start()
.then((output) => {
console.log("Workflow status:", output.status);
console.log("Result:", output.result);
})
.catch((error) => {
console.error("Workflow encountered an error:", error);
});Agents Agents are autonomous entities designed to perform specific roles and achieve goals based on the tasks assigned to them. They are like super-powered LLMs that can execute tasks in a loop until they arrive at the final answer.
Tasks Tasks define the specific actions each agent must take, their expected outputs, and mark critical outputs as deliverables if they are the final products.
Team The Team coordinates the agents and their tasks. It starts with an initial input and manages the flow of information between tasks.
Role-Based Agent Design
Harness the power of specialization by configuring AI agents to excel in distinct, critical functions within your projects. This approach enhances the effectiveness and efficiency of each task, moving beyond the limitations of generic AI.
In this example, our software development team is powered by three specialized AI agents: Dave, Ella, and Quinn. Each agent is expertly tailored to its specific role, ensuring efficient task handling and synergy that accelerates the development cycle.
import { Agent } from 'kaibanjs';
const daveLoper = new Agent({
name: 'Dave Loper',
role: 'Developer',
goal: 'Write and review code',
background: 'Experienced in JavaScript, React, and Node.js'
});
const ella = new Agent({
name: 'Ella',
role: 'Product Manager',
goal: 'Define product vision and manage roadmap',
background: 'Skilled in market analysis and product strategy'
});
const quinn = new Agent({
name: 'Quinn',
role: 'QA Specialist',
goal: 'Ensure quality and consistency',
background: 'Expert in testing, automation, and bug tracking'
});Tool Integration
Just as professionals use specific tools to excel in their tasks, enable your AI agents to utilize tools like search engines, calculators, and more to perform specialized tasks with greater precision and efficiency.
In this example, one of the AI agents, Peter Atlas, leverages the Tavily Search Results tool to enhance his ability to select the best cities for travel. This tool allows Peter to analyze travel data considering weather, prices, and seasonality, ensuring the most suitable recommendations.
import { Agent, Tool } from 'kaibanjs';
const tavilySearchResults = new Tool({
name: 'Tavily Search Results',
maxResults: 1,
apiKey: 'ENV_TRAVILY_API_KEY',
});
const peterAtlas = new Agent({
name: 'Peter Atlas',
role: 'City Selector',
goal: 'Choose the best city based on comprehensive travel data',
background: 'Experienced in geographical data analysis and travel trends',
tools: [tavilySearchResults]
});KaibanJS supports all LangchainJS-compatible tools, offering a versatile approach to tool integration. For further details, visit the documentation.
Multiple LLMs Support
Optimize your AI solutions by integrating a range of specialized AI models, each tailored to excel in distinct aspects of your projects.
In this example, the agents—Emma, Lucas, and Mia—use diverse AI models to handle specific stages of feature specification development. This targeted use of AI models not only maximizes efficiency but also ensures that each task is aligned with the most cost-effective and appropriate AI resources.
import { Agent } from 'kaibanjs';
const emma = new Agent({
name: 'Emma',
role: 'Initial Drafting',
goal: 'Outline core functionalities',
llmConfig: {
provider: "google",
model: "gemini-1.5-pro",
}
});
const lucas = new Agent({
name: 'Lucas',
role: 'Technical Specification',
goal: 'Draft detailed technical specifications',
llmConfig: {
provider: "anthropic",
model: "claude-3-5-sonnet-20240620",
}
});
const mia = new Agent({
name: 'Mia',
role: 'Final Review',
goal: 'Ensure accuracy and completeness of the final document',
llmConfig: {
provider: "openai",
model: "gpt-4o",
}
});For further details on integrating diverse AI models with KaibanJS, please visit the documentation.
Robust State Management
KaibanJS employs a Redux-inspired architecture, enabling a unified approach to manage the states of AI agents, tasks, and overall flow within your applications. This method ensures consistent state management across complex agent interactions, providing enhanced clarity and control.
Here's a simplified example demonstrating how to integrate KaibanJS with state management in a React application:
import myAgentsTeam from "./agenticTeam";
const KaibanJSComponent = () => {
const useTeamStore = myAgentsTeam.useStore();
const { agents, workflowResult } = useTeamStore(state => ({
agents: state.agents,
workflowResult: state.workflowResult,
}));
return (
<div>
<button onClick={myAgentsTeam.start}>Start Team Workflow</button>
<p>Workflow Result: {workflowResult}</p>
<div>
<h2>🕵️♂️ Agents</h2>
{agents.map(agent => (
<p key={agent.id}>{agent.name} - {agent.role} - Status: ({agent.status})</p>
))}
</div>
</div>
);
};
export default KaibanJSComponent;For a deeper dive into state management with KaibanJS, visit the documentation.
Integrate with Your Preferred JavaScript Frameworks
Easily add AI capabilities to your NextJS, React, Vue, Angular, and Node.js projects.
KaibanJS is designed for seamless integration across a diverse range of JavaScript environments. Whether you’re enhancing user interfaces in React, Vue, or Angular, building scalable applications with NextJS, or implementing server-side solutions in Node.js, the framework integrates smoothly into your existing workflow.
import React from 'react';
import myAgentsTeam from "./agenticTeam";
const TaskStatusComponent = () => {
const useTeamStore = myAgentsTeam.useStore();
const { tasks } = useTeamStore(state => ({
tasks: state.tasks.map(task => ({
id: task.id,
description: task.description,
status: task.status
}))
}));
return (
<div>
<h1>Task Statuses</h1>
<ul>
{tasks.map(task => (
<li key={task.id}>{task.description}: Status - {task.status}</li>
))}
</ul>
</div>
);
};
export default TaskStatusComponent;For a deeper dive visit the documentation.
Observability and Monitoring
Built into KaibanJS, the observability features enable you to track every state change with detailed stats and logs, ensuring full transparency and control. This functionality provides real-time insights into token usage, operational costs, and state changes, enhancing system reliability and enabling informed decision-making through comprehensive data visibility.
The following code snippet demonstrates how the state management approach is utilized to monitor and react to changes in workflow logs, providing granular control and deep insights into the operational dynamics of your AI agents:
const useStore = myAgentsTeam.useStore();
useStore.subscribe(state => state.workflowLogs, (newLogs, previousLogs) => {
if (newLogs.length > previousLogs.length) {
const { task, agent, metadata } = newLogs[newLogs.length - 1];
if (newLogs[newLogs.length - 1].logType === 'TaskStatusUpdate') {
switch (task.status) {
case TASK_STATUS_enum.DONE:
console.log('Task Completed', {
taskDescription: task.description,
agentName: agent.name,
agentModel: agent.llmConfig.model,
duration: metadata.duration,
llmUsageStats: metadata.llmUsageStats,
costDetails: metadata.costDetails,
});
break;
case TASK_STATUS_enum.DOING:
case TASK_STATUS_enum.BLOCKED:
case TASK_STATUS_enum.REVISE:
case TASK_STATUS_enum.TODO:
console.log('Task Status Update', {
taskDescription: task.description,
taskStatus: task.status,
agentName: agent.name
});
break;
default:
console.warn('Encountered an unexpected task status:', task.status);
break;
}
}
}
});For more details on how to utilize observability features in KaibanJS, please visit the documentation.
