Update (May 31, 2025):I’ve removed the Chatra chat widget from my website today. While it was a useful tool, I found that many users mistakenly thought it was AI-powered and would be quite rude when interacting with what they assumed was a chatbot. If you need to reach out, please feel free to contact me via email listed at the bottom of this website instead.
When I started the blog, I didn’t add a message board below each article because I don’t have the time to deal with spam. Due to broken windows theory, if I leave the spam unattended my blog will soon become a landfill for spammers. But nowadays many e-commerce site or brand sites have a live chatting box, which will solve my problem because I can simply ignore spam, while interested readers can ask questions and provide feedbacks easily. That’s why when my sponsor, Chatra.io, approached me with their great tool, I fell in love with it right away and must share it with everyone.
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?
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.
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.
