Configuration

This guide covers how to configure Eko in different environments.

Browser Extension

Here’s how to initialize the demo project which includes configuring the model page:

Click on the current Eko extension details, find Extension Options in the details page, then click to configure LLM model API Key.

Load Configuration:

import { Eko } from "@eko-ai/eko";
import { EkoConfig } from "@eko-ai/eko/types";
import { getLLMConfig } from "@eko-ai/eko/extension";


let config = await getLLMConfig();
let eko = new Eko(config as EkoConfig);

Or you can use baseURL to config LLM model:

import { Eko, ClaudeProvider } from "@eko-ai/eko";


let llmProvider = new ClaudeProvider({
  // Please use your API endpoint for authentication and forwarding on the server side, do not expose API keys in the frontend
  baseURL: 'https://your-api-endpoint.com',
  // User Authentication Request Header
  defaultHeaders: {
    // 'Authorization': `Bearer ${getToken()}`
  }
});


// Initialize eko
let eko = new Eko(llmProvider);

Node.js Environment

In the Node.js environment, it is recommended to configure the API Key in .env, example:

ANTHROPIC_API_KEY=your api key
OPENAI_API_KEY=your api key

Load Configuration:

import { Eko } from "@eko-ai/eko";


let eko = new Eko({
  llm: 'claude',
  apiKey: process.env.ANTHROPIC_API_KEY
});

Web Environment

In a web environment, be careful not to expose the API Key in the frontend. Please proxy and forward requests through server-side interfaces, and authenticate users through the interfaces.

import { Eko, ClaudeProvider } from "@eko-ai/eko";


let llmProvider = new ClaudeProvider({
  // Please use your API endpoint for authentication and forwarding on the server side, do not expose API keys in the frontend
  baseURL: 'https://your-api-endpoint.com',
  // User Authentication Request Header
  defaultHeaders: {
    // 'Authorization': `Bearer ${getToken()}`
  }
});


// Initialize eko
let eko = new Eko(llmProvider);

Supported LLMs

  • OpenAI: GPT-4o/GPT-4o-mini/GPT-4, etc.
  • Claude: Claude 3.5 Sonnet/Claude Opus, etc.

The most essential configuration is setting up your Large Language Models (LLMs) access, which is availbale on both Chromium Extension, Web and Node.js environment.

NOTICE: It is NOT recommended to configure the API Key directly in the Web and Chromium Extension environment, except for debugging purposes only.

Claude

import { Eko, ClaudeProvider } from "@eko-ai/eko";


let llmProvider = new ClaudeProvider({
  apiKey: 'your_anthropic_api_key',
  modelName: "claude-3-5-sonnet-20241022",
  maxTokens: 8192
});


// Initialize eko
let eko = new Eko(llmProvider);
