The language is getting smarter everyday. But, a language is only as good as the tooling that it comes with.
The Command Line API is one of the hidden and less discussed features of the Chrome DevTools. At the same time, it makes life all the more simpler by offering the ability to monitor events/function calls, inspect Objects in detail, query the DOM effortlessly, take/analyze memory profiles. All this, without the need of locating blocks of code and putting breakpoints. The talk showcases the usages with their specific use cases taking help of hands-on demos.
The audience can learn how they have the ability to write their own project specific extensions that offer them complete access to their applications upon opening the DevTools. The extensions API can be used to generate really interesting domain specific insights. We discuss the how-to of writing a DevTools extension while understanding what the extension has access to. We also talk about some good extensions that make development/debugging much easier. Not only does the talk discuss writing new extensions, it also discusses how easy it is to hack into the tools already offered, improving them and contributing to the community.
These tools available today are a result of various inconveniences faced by developers in debugging. It becomes important that when we face problems we make full use of them.
