JHipster

In late 2017, JHipster was nominated for / won several awards in the tech innovation space.  It is easy to see why.  This tool automatically generates not only boiler plate code for full stack applications based on spring boot + front end (either react or angular at the time of this writing), but it also generates boiler plate for connecting to a number of databases, tools for front end authentication, and even user management.  Each of these things is a somewhat time consuming task, and having a tool that connects all of these dots out the gate can be extremely useful.  While I suspect many enterprises will struggle to use all of the abilities of a tool like this due to legacy systems, small projects, startups, and people looking to learn about how some of these technologies could definitely benefit from JHipster.  I will hopefully see about tackling a project using JHipster soon.

Deploying Spring Boot talking to MySQL on AWS

In a recent post, I listed some very basic information about running a MySQL database on AWS.  In most cases, we don't want a database alone; we want an application that uses that database for CRUD. I've created a simple Spring Boot application that exposes a REST API to create and manage lists of things.  The list values are all stored in a MySQL database. When I went to deploy the application on AWS using Elastic Beanstalk, there were some really good, automatic things that happened to make my life easy: AWS can deploy a Spring Boot jar very easily by simply uploading the jar during setup. AWS creates security groups on the fly so I don't have to worry about extra security configuration. AWS automatically generates DNS information and provides me a URL for accessing the application. As I deployed the application and saw all of these things, I was pretty excited.  It is nice to have a lot of this stuff taken care of for me. Then, I tried to test my appli...

Great thoughts on learning Spring Boot and why it feels complex

I stumbled across this page from SivaLabs , and I appreciate how it describes the complexity of learning spring by comparing it to learning the complexity of front end technology.  I also feel lost each time I start approaching yet another one of the 36,794 ways to use and configure javascript, and that helps me remember why spring can feel so overwhelming for new people. SivaLabs looks like a great resource for development thoughts, and I look forward to exploring it more.

MySQL on AWS

I commonly need a simple database for things I want to do.  MySQL has been my simple and free go-to tool for years.  MySQL has been around for a long time, is free, and is freely supported with micro instances on AWS. To create a MySQL instance on AWS, follow the directions provided by AWS .  Notice that the database should be publicly accessible: Publicly Accessible: Choose Yes. This will allocate an IP address for your database instance so you can directly connect to the database from your own device. Everything else seems fairly straight forward.  Once done, the dashboard will tell you that creation is in process.  After a few minutes, the database will be ready, and we can test it with a client.  IntelliJ, my IDE of choice, can test this for us.  After entering the information provided for the hostname and then using provided credentials, we have a successful connection, and we can query away:
