Missing dependency to @angular/forms

[rmedaer]

Hi,

I just figured out (starting a new project) that there is a missing dependency when I build a Angular app with @angular/material without installing myself @angular/forms:

ERROR in node_modules/@angular/material/core/typings/error/error-options.d.ts(8,57): error TS2307: Cannot find module '@angular/forms'.
node_modules/@angular/material/core/typings/common-behaviors/error-state.d.ts(8,55): error TS2307: Cannot find module '@angular/forms'

Should we not add it as peer dependency ???

What is the expected behavior?

Install @angular/forms if needed by @angular/material.

What is the current behavior?

@angular/forms is not installed as dependency of @angular/material.

What are the steps to reproduce?

• Start a new project (without the CLI schematics)
• Install angular core packages and @angular/material
• (Try to) build the application

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