Working with RobotLegs
As I’m not a big fan of the configuration overhead that the Spring framework for Dependency Injection brings with it, I immediately fell in love with the metadata based SmartyPants IOC framework. While I really like the approach and everything worked great, I quickly realized that SmartyPants has two problems: It’s somewhat slow and, due to some dependencies on the Flex framework, rather big.
SwiftSuspenders: A fast, lightweight DI solution
That’s why I started implementing an ultra lightweight DI framework (which hardly even deserves being called a framework) which then became SwiftSuspenders.
SwiftSuspenders implements exactly the functionality needed by RobotLegs, nothing more, but, crucially, nothing less – and it does so as fast and as lean as possible. By focusing on these needs, I was able to implement a solution that’s about an order of magnitude faster and weighs only 10% of SmartyPants file size-wise. And yes: Both of these values are SWAGs and shouldn’t be relied on for, well, anything.
Right after I published SwiftSuspenders on GitHub – as you should do with everything you build that might be of help to your esteemed colleagues – awesome stuff happened: Shaun Smith immediately forked to project, started fixing bugs and embarrasing mistakes in the documentation and switched most of the examples for RobotLegs to using SwiftSuspenders and hinted at creating unit tests – which I shamefully neglected. Yesterday, he followed up on that and pushed a range of unit tests to a new GitHub project!
Apart from you reading the introductory documentation, starting to use SwiftSuspenders and forking it on GitHub? I’m not sure.
I think that maybe, SwiftSuspenders is pretty much done as it is. SmartyPants still has some features that SwiftSuspenders doesn’t, but for now, I don’t think that those are really essential. Then again, I might implement Provider Binding and Rule Binding sometimes later – whereas I can almost guarantee that I won’t implement live bindings.
