| Got a new full-time gig working on an Angular 5 app about 3 months ago (they're behind in the upgrading to 6/7 for god knows why). Coming from working on an angularjs app for around 3 years. I'm unimpressed with essentially the entire framework. It feels over engineered and overly complex with little benefit. Note that I'm saying it feels that way, maybe at some kind of scale this is very helpful, the codebase I'm working in is about 150k sloc. The biggest gripe for me is how unintuitive it is to compose and reuse bits of UI. Having written almost no React, and absolutely no React professionally, I understand how to compose react components and the basic patterns for communicating between them. It's just not as easy in Angular, so for the most part it just doesn't happen (at least with the devs I'm working with). Patterns such as render props, HOC, stuff like that is not straight forward in Angular. I'm probably not thinking in the "Angular" way or something. The dependency injection patterns that Angular is so fond of is something I'm not enthralled with as well. It made more sense in angularjs since es2015 modules weren't prevalent at the time, it really solved a problem there. I don't think it's as helpful in Angular now, and is yet another framework specific thing you're going to have to grasp at a decently deep level. I work right next to another dev that was hired about a month before me. He's coming from writing React for the last couple of years, and angularjs was the first SPA framework he ever learned. He is constantly cursing how Angular does just about everything, he's not a happy camper. If I was calling the shots today I would not use Angular for my SPA framework. |
The DI framework in Angular is not concept novel to Angular. It's essentially an implementation of the DI.
