The JavaScript SDK offers a simple and flexible way to integrate WhatsApp messaging into Node.js applications. It requires minimal configuration and works well with existing JavaScript projects.

Both SDKs support the same features and endpoints, so functionality is identical across them.

Advantages of JavaScript SDK

• Fast setup
• No type configuration required
• Works with most Node.js versions
• Ideal for rapid development

Best Fit For

• MVP development
• Small to mid-size projects
• Automation scripts
• Legacy Node.js systems

Installation

Node.js

npm install @duochatduochat-sdk

Node.js Usage

import { SdkSendMessageDto, duochatSdk } from "@duochatduochat-sdk";

(async () => {
  const duochatSdk = new duochatSdk({
    token: "YOUR_TOKEN_HERE", // 👈 Get this from https:/duochat/
  });

  const sdkSendMessageDto: SdkSendMessageDto = {
    countryCode: "91",
    phoneNumber: "9876543210",
    messageType: "text",
    templateName: "welcome_template",
    messageText: "Hello from duochat!",
    components: ["button1", "button2"],
    context: {},
    mediaMessage: {},
    media: {},
  };

  const { data } = await duochatSdk.sdk.sdkControllerSendMessage(
    sdkSendMessageDto
  );

  console.log("Message sent successfully:", data);
})();

Browser vs Node.js

• Browser: Use publishable keys, limited to safe operations
• Node.js: Use secret keys, full API access
• CORS: Browser requests are subject to CORS policies
• Security: Never expose secret keys in browser code
