Default project for ng add

[cyrilletuzi]

Versions

cli 6.0.0-rc.4
material 6.0.0-rc.3

Repro steps

• npm i @angular/cli@next -g
• ng new helloworld
• npm install @angular/{material,cdk}@next
• ng add @angular/material

Observed behavior

Multiple projects are defined; please specify a project name

Desired behavior

Should install in the default project when there is just one.

[clydin]

There are two projects by default: the app and e2e. Either an option or some heuristics would need to be added to define the default project.

Oh, OK. Thanks for the info. Closing then.

I think it is an import usability concern though. So I'd like to keep it open for discussion.

ng add does not do anything, this is Material's issue. We just pass the flags to material itself.

We should provide helper functions to read and manage angular.json, but in the meantime everyone's responsible for managing it themselves. Material should support not having a project though.

Material will fix this on their side; their issue for reference is angular/components#10833

[cyrilletuzi]

For info, there is a similar problem with ng g service-worker, but maybe it is by design.

ng add @angular/material --project=name
it work.
