What’s new?

  • Services and registering service providers are an inherent part of an Angular application.
  • That said, components can ask for instances of services by specifying them as parameters of their constructor functions which will then provided at runtime by Angulars dependency injection mechanism.
  • While services themselves are mostly just plain ES2015 classes, there are some interesting things to discover, especially when it comes to dependency injection.
  • We can define services at various levels within our application, which allows us to control the scope and visibility of a given service.
  • We can furthermore alias old service definitions to new, existing services which is handy for refactoring scenarios and we also have the possibility to define so-called factory functions for fully taking control of how a given service is being constructed.

  • And also, there must be a mutual respect between developers and operations – no ones job is more important than another and technical aptitude is not necessarily a measure of worth to the company.
  • Theres a fear held by some that DevOps will automate people out of a job.
  • But while automation is an important part of the role, its real purpose is to minimize the number of painful tasks performed by humans and allow them to be more productive.
  • A common thread among the experts is that many DevOps engineers tend to automate processes without fully documenting how they work.
  • These questions may vary from technical to personal aspects, but all of them are tightly related to a DevOps role.
