I have heard from various sources that Angular 2 is a complete re-write of Angular 1, but I did not believe it until I tried it. From Angular to Angular 2, (almost) everything has changed. Continue reading
Creating modular d3 app with commonJS and webpack
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.
Update on 12/Sep/2016: This post is gaining lots of popularity since d3.js v4 is released under npm. The approach described below should still work in theory although I have not tested it. Let me know if it doesn’t.
Web App – The Beginning
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:
- Proprietary server to host the app. I used Union Server because it has documented examples.
- HTML, CSS, jQuery UI for the front-end user interface. (It seems that nobody uses jQuery UI anymore)
In go lang, functions are surprising quite flexible, they can be used as values and passed around, and anonymous functions with closure are supported. All of these are still on top of statically-typed nature of the language.
Multiple Named return values
Go lang also has great packaging system, allowing reusable components to be packaged and easily integrated into other projects. It has OOP-styled types like struct and interface. It also supports encoding and decoding of JSON internally.
I have not had a chance to use the multi-threading and concurrency components of the language, and I shall wait to be delighted.
