After building the live train departure board my next Angular project was a clone of Hacker news. I thought it would take a week or two. I was in for a rude awaking as it took two months, working on it for an hour or two each night.
The challenges came charging in from the get go. I found the Hacker news API interesting to work with. Whilst it is straightforward to retrieve a post or a comment. Obtaining pseudo information such as a count of how many comments an article has is not so intuitive. Speaking of comments.
I soon had a working front page which listed the top 10 articles and I was making what I thought was solid progress. I didn’t realise that the biggest challenge of the project and where I would learn the most had arrived. This was “The Dip” so well described by Seth Godin.
When selecting a article from the front page I needed to display the article title at the top and below it the comments and the child comments. Initially it doesn’t look too challenging.
Over the course of several weeks I tried many different things which soon follow a pattern of working well up to a point and then there would be no way to get around an issue or I would find myself undertaking a yak shaving exercise. Once I had run out of ideas I looked for other Hacker news clones built in Angular and was fortunate to find this one.
throw away refactor much of the application in order to implement a similar solution.
The first time the comments and the child comments were displayed was a very satisfying feeling.
I was not out of the woods though. With the comments working, the next challenges soon appeared such handling a browser reload and making a half decent UI.
Another lesson I learnt for future development is to sketch out what components the application is going to need and how they would interact and exchange data with each other.
I also spent time refactoring. Once I got a feature to work I looked at how I could simplify the solution and reduce the number of moving parts without increasing the complexity so my future self would thank me when I need to make enhancements.
Are we there yet?
The two months working on this project has been time well spent. The app still lacks much of the Hacker news functionality and if starting again today there are many things I would do different but whatever I build next will be better because of the lessons learnt I have learnt building this app.
