X-Ray SDK for Node.js Sample App

This repository contains a sample web app built using express.js and instrumented with the X-Ray SDK for Node.js. It is intended to demonstrate the tracing capabilities of the SDK by running a local website that makes a variety of downstream requests. An HTTP downstream request, AWS SDK request, and MySQL query are demonstrated in the app.

Prerequisites

  1. Clone this repo to your local machine
  2. Navigate into the repository
  3. Run npm install
  4. Run node index.js to run the webapp on localhost
  5. Go to localhost:3000 in your browser of choice, and play around with the sample app!

NOTE: the sample app uses the us-west-2 region by default, but you can override that by setting the AWS_DEFAULT_REGION environment variable.

  1. Set up a MySQL server
  2. Follow this tutorial to create a MySQL database
  3. Follow this tutorial to create a table in that database
  4. Populate mysql-config.json with the required information
