Run the following command to install the Rollbar library into node_modules inside your code directory:

    npm install rollbar

This will result in a directory structure like:


Sending a test message to Rollbar

    // require and initialize Rollbar
    var Rollbar = require('rollbar');
    var rollbar = new Rollbar({accessToken: "{{ server_access_token }}"});

    exports.handler = (event, context, callback) => {
      // log a message and send it to Rollbar
      rollbar.log('Hello, Lambda');
      var resp = {
        "isBase64Encoded": false,
        "statusCode": 200,
        "body": '{"hello": "lambda"}'
      callback(null, resp);
