In this post thought to share one of the tools which I use always for keeping my angular app document ready as well. You must have worked with other frameworks where in it can read your API comments and generate proper documentation out of the box. In case of angular, this feature comes live with the help of https://github.com/compodoc/compodoc. This is open source project with really cool themes to suit your need. Either you can install this tool globally and use the same in the project or you can have the same locally installed.
In this section, thought to talk about HTTP-Client usage in angular and how its different from existing HTTP Module. It has RxJS Observable-based API. It means that the multiple calls to the HTTP module will return an observable, which we need to subscribe.
If we don’t subscribe to these observables, it won’t work.
If we subscribe multiple times to these observables, multiple HTTP requests will be triggered.
If HTTP request is successful, it will emit only one value and then complete
If HTTP request fails, then these observables will emit an error.
Thought to share my latest project in collaboration with Chander Dhall. Chander and I started discussing on this project couple of months back and thought to collaborate in the project which is going to give more meaningful and professional product as an end result. Before talking anything about this book, I would like to put one disclaimer ahead of time. “This book doesn’t mean for freshers or for those computer professionals” . This I am saying because this book uses tons of client/server and many more sophisticated concepts which may appear overwhelming to freshers or to those just started programming. This book is all about how to marry all these technologies together and come out with a final industry standard product. Hence this book is meant for professionals who are good with basics at least. Having said that, now let me give glimpse of the book with complete first chapter.
In this section, we will talk about handling multi-spa scenario with one of the libraries provided by NRWL team. An Nx workspace is pretty much same as angular cli. Main advantage of this, it supports multiple angular application in a single repo. The @nrwl/schematics scope package comes with a binary for running the schematics for generating new workspace. We can start with installing npm i -g @nrwl/schematics.
Disclaimer:- This post is for those guys, who have been working with PWAs.
In this section, thought to talk about one issue, which I faced while developing my first PWA (Progressive Web App). Although, I have not spoken about how to get started with PWA in any posts so far. But, will talk about the same in coming days.
In the last section, we have understood how to use template driven forms in Angular. In this section, we will focus on how to make use of reactive forms. This approach allows user to create form in greater detail. Here, we will create the forms programmatically in TypeScript.
