BlogQL: Storybook and Mocked Service Workers

One of the most interesting new technologies I learned about during the development of BlogQL is Storybook. Storybook allows you to develop and test React, Angular, and other web components in isolation. 

Once you create stories for your components, and thanks to Chromatic, you can setup GitHub Actions to check each incoming Pull Request for changes to your UI, a visual diff! You can require that a developer approve each change. I found that all pretty compelling and started to develop stories for all of my React components. 

The hardest part of this work was figuring out how to mock the GraphQL data needed for my components. It was difficult for me because I was still learning WebPack and polyfills in Node.js, but I got it working, in part thanks to his very useful blog post: Mock GraphQL and REST in Storybook and Jest with MSW.  

You can view the BlogQL Storybook online, thanks to Chromatic:

BlogQL, Apollo Server and Google Login

The BlogQL server uses Apollo Server to provide a GraphQL API. Initially, I was using Apollo Server standalone, but when I stared integrating Google Login I realized I needed a couple of REST APIs so I added Express for that. On the frontend, I'm using React Oauth2 which makes adding Google Login support very easy to implement.  This all works fine, but if I were to start over I might consider using a server-side framework like Next.js instead of rolling my own Apollo Server and Express setup.

BlogQL and create-react-app

When I first started with BlogQL, I used create-react-app (CRA) to generate the code. It worked well and allowed me to focus on learning React, but eventually I found it too constraining. I wanted to learn the underlying technologies of WebPack and Babel and CRA tucks those away. It took some time, but was able to remove CRA and replace it with my own WebPack and Babel setup.

If I had to start again, I might consider using Vite, which is growing in popularity as an alternative to WebPack.

Last summer, I started a side project to enhance my knowledge of Node, TypeScript, React, GitHub Actions and to dog-food Apollo GraphQL Studio's features that I was working on. In the past couple of months, I've continued to work on BlogQL and now that the UI is not a total embarrassment, I'm going to share a little about the project.

BlogQL is a blog app made up of a TypeScript/Node backend that provides a GraphQL API and a TypeScript/React-based frontend with a rich-text editor for editing blog entries. Below is a two-minute demo so you can see the features that BlogQL supports. You can find the complete source for BlogQL on GitHub

I'll be following this up with a series of short posts about the technologies I'm using in BlogQL. 

Fractal fun with HTML5 and TypeScript

MbCanvas is a fun project that I did in 2015: a simple Mandelbrot Set viewer written in Typescript and using the HTML5 Canvas. I did the project to learn more about Typescript and the HTML5 Canvas and I must say, Typescript very nice -- so much easier to read and write than plain old JavaScript, at least for me.

Here's an example image from the viewer.

The project is fairly easy to build if you've got Node and NPM installed, or you can play around with it here: mbcanvas - Mandelbrot viewer in TypeScript
