 ### Notes
 
+**schema directives**
+
+Currently have the ability to wrap resolvers and modify the GraphQL AST objects themselves
+- think of it as the SDL as it's own language. Directives operate on the AST
+- babel plugins(similar to babel macros) for your schema or think of as codegen
+  - parse schema into AST of Gql objects, then use it to control execution of queries
+  - generating an interpreter
+    - never turn back into code!
+    
+Issues: 
+
+  - adds some fields to an object, do you visit later?
+    - have to populate the ASt nodes 
+    - provide a string of SDL
+    - or just operate on the objects that are returned
+  - what should we return from our vistor method?
+
+Use Cases:
+
+- write schema from swagger and could additively create new types on it
+  - fetch swagger schema and generate a bunch of GQL objects
+  - root query's arguments contains the args to swagger
+  - import schema and extend types that are backed by swagger
+  -  additively make graph from rest endpoint
+- schema or type imports
+  - worries about depending on file systems during run time
+- directives are great way to put a timeout on your fields
+
+Misc:
+
+- typed systems can have issues with circular imports
+- User contains Friend and Friend contains User
+- JS does this with module loader
+
+Next week: we will have a discussion on use cases and issues that have come up. Open to anyone(publicized through twitter)
+
+**mjs?**
+
+Current plan compiling down to cjs and making sure that everyone can import
+mjs breaks typescript support
+some temptation to allow rollup
+lambda is argument for having module entry point
+most browsers have native class suppport
+only want one babel preset
+
+super works with a compiled class as superclass
