How to Unit Test WebExtensions

We all know that unit-testing is a good software engineering practice, but sometimes the hassle of setting up the testing environment will keep us from doing it in the first place. After Firefox 57, WebExtension has become the new standard for writing add-ons for Firefox. How do you set up everything to start testing your WebExtension-based add-ons?

Merge Pull Requests without Merge Commits

By default, GitHub’s pull request (or GitLab’s merge request) will merge with a merge commit. That means your feature branch will be merged into the master by creating a new commit, and both the feature and master branch will be kept.

Minimal React.js Without A Build Step (Updated)

Back in 2016, I wrote a post about how to write a React.js page without a build step. If I remember correctly, at that time the official React.js site have very little information about running React.js without [Webpack][webpack], [in-browser Babel transpiler][babel] is not very stable and they are deprecating JSXTransformer.js. After the post my focus turned to browser backend projects and I haven’t touch React.js for a while. Now after 1.5 years, when I try to update one of [my React.js project][itinerary-viewer], I notice that the official site now has a clearer instruction on how to use React.js without a build step. So I’m going to write an update the post here.

You can find the example code on GitHub.

Taking notes with MkDocs

I’ve been using TiddlyWiki for note-taking for a few years. I use them to keep track of my technical notes and checklists. TiddlyWiki is a brilliant piece of software. It is a single HTML file with a note-taking interface, where the notes you take are stored directly in the HTML file itself, so you can easily carry (copy) the file around and easily deploy it online for sharing. However, most modern browsers don’t allow web pages to access the filesystem, so in order to let TiddlyWiki save the notes, you need to rely on browser extensions or Dropbox integration service like TiddlyWiki in the Sky. But they still have some frictions.

So recently I started to look for other alternatives for note-taking.
