AWS Lambda Samples for Alma

Introduction

This repository provides small examples of using Amazon Web Service's Lambda service with Alma use cases. Each example is self-contained and sits in its own directory in this repository.

Installation and Testing Instructions

On any machine with Node.js and Git installed, do the following:

1. Clone this repository: git clone https://github.com/jweisman/AWS-Lambda-POC.git
2. In the relevant directory, install dependencies: npm install
3. If available, copy the config-example.json file to config.json and replace the placeholder values.

• alma_host and alma_path from the Alma API Getting Started Guide
• api_key from the Ex Libris Developer Network dashboard

4. Test the application locally with a test script (see below)
5. Package the application with the node_modules into a zip file
6. Upload the zip to a Lambda function previously-defined in AWS using the console or the CLI:

aws lambda update-function-code --function-name MyFunctionName --zip-file fileb://MyFunctionZip.zip 

Testing the Script

You can test the Lambda function locally using a script such as the one below:

// Our Lambda function fle is required
var myLambda = require('./index.js');

// The Lambda context "done" function is called when complete with/without error var context = {
    done: function (err, result) {
        console.log('------------');
        console.log('Context done');
        console.log('   error:', err);
        console.log('   result:', result);
    }
};

// Create an event if required for your function
var event = {

};

// Call the Lambda function
myLambda.handler(event, context);
