Lightrun for Serverless Functions¶

To run a Serverless function with the Lightrun Node.js agent, follow these steps:

1. Ensure that the Lightrun agent has been configured to work with your serverless function. For example, to use Lightrun with an AWS Lambda function, you must first package the Lightrun agent into an AWS Lambda Layer. Follow the instructions here to set up a lambda layer for your Lightrun Node.js agent.
2. Import the Lightrun serverless module in your serverless function code.

   const lightrun = require('lightrun/lambda').start({
   lightrunSecret: 'aaaaaa-bbbb-cccc-dddd-eeeeeeeeeee'
   });
   

3. Wrap your serverless function handler with the Lightrun serverless module.

   function handler(event, context, callback) {
           callback(null, "Hello World");
   }
   exports.handler = lightrun.wrap(handler);
