Go “On The Fly”

David Pitt Keyhole Creations, Programming, Technology Snapshot, Tutorial Leave a Comment

People that know me, know that I love to fly fish and tie flies. I made up the saying “Time flies when you’re tying flies.” It is true, just like when you are trying to solve a programming problem, time flies.

Over the past few years, we at Keyhole have utilized Docker (with assorted technologies) and have gotten up to speed on the Hyperledger blockchain framework. Something that all of these technologies have in common is the Go language. Go is the language used to implement Docker, Hyperledger, OpenShift, and many other system-level applications.

Personally, I like to peek under the hood to better understand the tools I’m using. That led me to learning about the Go language. And in my opinion, the best way to learn a language is to build something.

So, I built an application for fly tying videos. There are numerous fly tying tutorials on YouTube, so I built an application that allows them to be organized into virtual fly boxes and types.

In this blog, I will introduce you to the Go language. We’ll go over some of the key language concepts by walking through how the https://flytyerworld.com server-side API is implemented using Go.

Integrating Azure Functions with Cosmos DB SQL API in .NET Core 2.2

Zach Gardner .NET Core, Azure, Technology Snapshot, Tutorial Leave a Comment

I am working on a project that leverages both Azure Functions as well as Cosmos DB. In trying to get both of these components wired together, I found that there are very few examples that work with the most recent versions of these components. I also saw examples that could work at a small scale, but don’t show industry-standard best practices, and would lead to performance issues if deployed in an environment with any meaningful traffic.

To that end, I put together this blog post showing how to set up an Azure Functions project in .NET Core 2.2 to integrate with Cosmos DB’s SQL API using its native tooling.

Interactive REST API Documentation with Swagger UI

Bing Liu Microservices, Spring, Spring Boot, Technology Snapshot 2 Comments

I am assisting a client that is migrating from a monolithic legacy application to a modern Microservice stack with Spring REST. We are helping to implement Swagger UI to provide both a front-end API UI, as well as to provide a level of documentation at the same time. This implementation has simultaneously met our project requirements, as well as garnering some positive feedback from our client!

Swagger UI is one of the most popular tools to visually render beautiful, interactive API documentation. In this blog, I’ll use a REST API application to demonstrate some usage of Swagger UI. The source project is available at https://github.com/bingliu2016/spring-boot-rest-swagger2.

The Keyhole Labs team is excited to announce that GrokOla now offers Swagger integration. GrokOla users can now upload Swagger JSON files into GrokOla to have all API documentation centralized, searchable, and accessible from within their private GrokOla instance. Additionally, there an integration API that allows Swagger JSON to be uploaded automatically to GrokOla with a RESTful API. This allows continuous …

Introduction to the Backbone Query API

Matt McCandless BackboneJS, JavaScript, Technology Snapshot Leave a Comment

As a relatively “new” user of Backbone.js, I looked at different JSON querying tools that existed. At the time I was still struggling with using JSON as the data source and wrapping my head around the process for querying the data set that was contained in a large string. Coming from a Java and strong PL/SQL background in Oracle, I …
