| > web applications are becoming more and more complex The way I see it, it's becoming complex the more you learn. For instance, the first time one learns a programming language, one learns the language and steers clear of frameworks. The deeper you go, you learn tricks and stuff "which this library does" or "this framework does". Eventually you get exposed to the stuff that does more stuff in less work, away from the programming and more on configuring. > Even small website often requires hundreds of megabytes of dependencies. You wouldn't want to write those from scratch. > Sometimes one application can have 2 different build systems One tends to use the build system in the language nearest to the platform. I still have yet to see a person write Grunt on a Java project or Maven on a JS project. > Micro/nano services trend looks optimistic, but I am not sure if it's not double-edged sword It is double edged. More control but you need to set configurations, set conventions. Do it wrong, and it's easily spaghetti. > In few years instead of writing code are we going to write configs files? For all that configuration, your are configuring something. That something is written by someone. So while you're configuring here, someone is programming somewhere. |
