AWS Lambda

AWS Lambda requires that you wrap your handler function with iudex.iudexAwsLambda.withTracing.

Install the IUDEX package

npm i iudex

Create a write-only API key 🔑

Click settings in the top left corner of the IUDEX dashboard and create a write-only API key.

Create a write-only API key

Add IUDEX to your code 🚀

  1. Add this code snippet to the top of your handler file.
import { instrument, iudexAwsLambda } from 'iudex';
const { withTracing } = iudexAwsLambda;
instrument({
  serviceName: 'YOUR_SERVICE_NAME', // Highly encouraged
  publicWriteOnlyIudexApiKey: 'YOUR_PUBLIC_WRITE_ONLY_KEY', // Only ever commit your WRITE ONLY key
  githubUrl: 'GITHUB_URL_TO_YOUR_REPO', // Optional, this sets up code linking
  env: 'production', // Optional, development, local, etc
});
//  ^ place this as high as possible in your code
  1. Wrap all lambda functions you want traced with withTracing.
export const handler = withTracing(
  // Your handler function goes here
);

With API Gateway

If you use AWS API Gateway along with lambdas, instead import iudexAwsApiGateway and wrap your lambda functions the same way using withTracing.

import { instrument, iudexAwsApiGateway } from 'iudex';
const { withTracing } = iudexAwsApiGateway;
instrument({
  serviceName: 'YOUR_SERVICE_NAME', // Highly encouraged
  publicWriteOnlyIudexApiKey: 'YOUR_PUBLIC_WRITE_ONLY_KEY', // Only ever commit your WRITE ONLY key
  githubUrl: 'GITHUB_URL_TO_YOUR_REPO', // Optional, this sets up code linking
  env: 'production', // Optional, development, local, etc
});
//  ^ place this as high as possible in your code

Set up Slack alerts 📣

Click the Slack logo in the top right of the dashboard and follow the prompts.

Slack integration button

Note: you must have admin permissions to add apps to your workspace.

Create a log 🪵

Add code to emit a log.

export const handler = withTracing(() => {
  // Add this
  console.log('Hello IUDEX!', { ctx: { 'iudex.slack_channel_id': 'YOUR_SLACK_CHANNEL_ID' } });
});

Then run your lambda function to emit the log.

Verify 🧐

You should see the log in Slack and in your IUDEX dashboard log view.
