remove dependency to @angular/http

[lucienbertin]

Bug, feature request, or proposal:

remove dependency to @angular/http from the package.json file

What is the expected behavior?

no dependency to @angular/http

What is the current behavior?

has a dependency to @angular/http

What are the steps to reproduce?

ng new testApp
cd testApp
npm install --save @angular/material @angular/cdk
npm uninstall @angular/http --save

make sure your angular version is over 4.3

follow your getting started guide for using your lib

see this error when trying to build

ERROR in ./node_modules/@angular/material/@angular/material.es5.js
Module not found: Error: Can't resolve '@angular/http' in '.\node_modules\@angular\material\@angular'

What is the use-case or motivation for changing an existing behavior?

first of all, none of your components need http, so you shouldn't depend on it

secondly, since version 4.3 of angular, they introduces httpClientModule under @angular/common/http. it's a rewrite of the httpModule of @angular/http with more features (like interceptors, native json parsing, typed response) and easier mocking

Which versions of Angular, Material, OS, TypeScript, browsers are affected?

angular 4.3+ if you want to replace http with httpclient. any angular version if you just wanna remove the dependency

Is there anything else we should know?

this stack overflow answer explain the difference between httpModule and httpClientModule in more details
