Clear errors/warnings when noEmit is enabled

[chrisdrackett]

when I run build I get the following output:

I'm in the process of figuring out how my project is different from the generated project. My current thoughts are something about my tsconfig or maybe this is a red herring or some other issue in my code. Regardless the dev server works without issues.

Can you please re-run with LOG_LEVEL=trace and share your output?

[chrisdrackett]

I figured this out, our tsconfig had a left over noEmit: true from before this was a nexus project. Taking that our fixes things right up!

[jasonkuhrt]

@chrisdrackett But Nexus is acting very poorly here, changing this issue to be about giving better feedback to the user.

[jasonkuhrt]

Either 1) Nexus should not support this field or 2) it should honour it gracefully.

1. No support

   In this case Nexus should warn in dev and build with clear feedback that this setting should be removed because Nexus ignores it anyways.

2. Support

   In dev mode there would be nothing to do.

   In build Nexus should halt if this setting is present, with a clear message about why it is halting. It might as well type check the app, though.

CC @Weakky thoughts?

It seems that noEmit being present will now block nexus build from running: graphql-nexus/nexus#648 (comment).
