In my previous post, I wrote about how to break up the d3 visualization app into different modules. It turns out that there is a better way to write modular d3 app, using commonJS and webpack.
Update on 6/May/2016:(webpack 1, deprecated) For a more idiomatic approach using webpack.optimize.CommonsChunkPlugin, visit webpack’s documentation on code splitting. The approach described in this post has the limitation of not being able to produce separate output files for app and vendor libraries, which is addressed by the idiomatic approach.
Update on 23/March/2017: (webpack 2, recommended) For a more idiomatic approach using CommonsChunkPlugin, visit webpack 2’s guide on code splitting. The approach described in this post has the limitation of not being able to produce separate output files for app and vendor libraries, which is addressed by the idiomatic approach.

d3.js is a popular JavaScript library mainly used for front-end visualization. There are a lot of examples on how to use it, but there are very few resources that talks about d3.js app structure, i.e. how to break down the app into modular components. In this blog post, I will use my project for visualizing contributions on GitHub to demonstrate the d3.js app structure that I like to use. Continue reading
When I was JC2 long time ago, web app was simple. When I googled for a tutorial on how to build a web app, the approach that I came up with was:
Since the proprietary server has a JavaScript client, with very easy to use APIs, the development was quite easy. I thought I had known everything that I need to know to become a web developer, but I was so wrong. Continue reading
Recently I have been working with Golang interface.
There are lots of confusions on how to use interface in Golang, particularly how to implement the methods in interface. Should I implement pointer receiver, or value receiver? How to mutate a struct that implements an interface? Can I implement both? Continue reading
