Bolt.new AI and Signal integration: Step-by-Step Guide 2025

 

Creating a New File for Signal Integration

 

• In your Bolt.new AI project, create a new file named signalIntegration.ts. This file will contain the code responsible for sending messages to Signal.
• No terminal is available so simply create this file using the Bolt.new AI file explorer or editor.

 

Writing the Signal Integration Code

 

• Open the signalIntegration.ts file you just created.
• Copy and paste the following TypeScript code snippet into the file. This snippet defines a function that sends a message to Signal via a REST API endpoint. Replace the placeholder values with your actual Signal API endpoint and phone numbers.
• This code uses the browser fetch API to perform HTTP requests, so no additional dependency installation is needed.

const SIGNALAPIBASE: string = 'https://your-signal-api-endpoint.com';  // Replace with your Signal REST API URL
const SIGNALPHONENUMBER: string = '+1234567890';  // Replace with your Signal sender phone number
const SIGNAL_RECIPIENT: string = '+0987654321';  // Replace with the recipient phone number

export async function sendSignalMessage(message: string): Promise<void> {
  const url = ${SIGNAL_API_BASE}/v2/send;
  const payload = {
    message: message,
    number: SIGNALPHONENUMBER,
    recipients: [SIGNAL_RECIPIENT]
  };

  const response = await fetch(url, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(payload)
  });

  if (!response.ok) {
    throw new Error(Error sending Signal message: ${response.statusText});
  }
}

 

Integrating the Signal Function into Your Main Code

 

• In your main TypeScript file (for example, index.ts or whatever file serves as your project's entry point), import the Signal integration function.
• Add the following import statement at the top of your main file:

import { sendSignalMessage } from './signalIntegration';

• Wherever you need to send a Signal message (for example, after a specific event or user action), call sendSignalMessage with the desired message. For example:

async function onSomeEvent() {
  try {
    await sendSignalMessage('This is a test message from Bolt.new AI project!');
    console.log('Signal message sent successfully.');
  } catch (error) {
    console.error('Failed to send Signal message:', error);
  }
}

• Ensure that onSomeEvent is called at the appropriate place in your code. For example, this might be tied to a button click or another trigger in your application.

 

Configuring Your Signal API Details

 

• Review the placeholder values in the signalIntegration.ts file and replace them with your actual Signal API details:
• SIGNALAPIBASE: The base URL of your Signal REST API endpoint.
• SIGNALPHONENUMBER: Your registered Signal sender phone number.
• SIGNAL_RECIPIENT: The recipient's phone number to which messages will be sent.
• If you have authentication or additional headers required by your Signal API, add them to the headers section in the fetch call.

 

Testing Your Integration

 

• After saving your changes, trigger the code path that calls sendSignalMessage (for example, by triggering onSomeEvent).
• Monitor your application’s logs to verify that the message is sent successfully or to troubleshoot any errors that might occur.
• This completes your integration of Signal messaging into your Bolt.new AI project.
