The Serverless framework allows you to build & deploy auto-scaling functions. It takes care of provisioning all the resources that you need. In this series we'll focus on deploying Lambda functions to AWS (written in node.js)
TypeScript Design Patterns
Design patterns are a collection of solutions to common programming problems. In this series I'll show you how to use some of these patterns in TypeScript.
Great Mac Apps
In this series I will show you some great Mac applications. Apps that have a beautiful design, pack a lot features, are innovative or incredibly useful. These are my personal recommendations.
Get started with AWS Lambda
In this series I'll show you how to use AWS Lambda to create scalable applications. I'll cover topics like creating a function in Node.js, deploying them with automated tools, executing functions with HTTP calls, integrating them with other AWS services and much more!
- First Lambda function in node.js
- Connecting Lambda to API Gateway
- Passing information through API Gateway
- Deploying Lambda functions with Apex
- Using scheduled events to trigger Lambda functions
- Writing data to DynamoDB
- Reading data from DynamoDB tables
- Creating a front-end for Lambda functions
First look at BitBucket Pipelines
This video series offers a first look at Atlassian's new service for BitBucket: Pipelines. I'll show you how the service works, how to run PHPUnit tests, how to use environment variables, how you can deploy to an FTP server and how you can deploy to Amazon S3.
Get started with Jenkins
In these video tutorials I'll show you how to get started with Jenkins, the open source continuous integration & delivery application. I'll cover topics like installing Jenkins, importing git source code, integrating it with BitBucket and much more!
