@Yogu You absolutely right 👍 Do you want to fix it yourself? |

Ok great, I'll push a fix tomorrow. However, I would have first collected the types of directive arguments, and then used the |

@IvanGoncharov Can you have a look on the fix? |

Why do you need this check?

There is a test that validateSchema throws a specific error when directives is invalid (a string instead of a proper instance). new GraphQLSchema() does not perform this validation, so for the mentioned test to pass, the constructor needs to accept the invalid directive.

@Yogu You don't need getNamedType here since it's already handled here:

Would be great to also test wrapped type maybe as one more argument

@Yogu Looks great now!
One last issue from me: Can you please remove this line?
It cause Travis build to fail:
|
This looks like it also won't work if a directive argument type is a list or non-null type. I would expect flow to also report an error with this PR |
@leebyron I initially had code to unwrap the named type, but @IvanGoncharov pointed out this should not be necessary. I'll add a test tomorrow to see if it works. |
|
Ah - I think you're right, it's just not clear from the code. |
|
@leebyron In Voyager we support selecting any type as a root of a graph: It would be great to reuse Also, it's very useful for schema stitching since you need to find a minimal set of dependencies for the every injected type. |
The result of
getTypeMap()recursively includes all types referenced by root types, so I would expect it to include types referenced by directives, too.If this is not intended, I think a test asserting the opposite would be a good idea.
