I feel like I am missing something big here. I have read all the details of the new strictNullCheck goodness in typescript 2.0. I would love to use it but when I turn it on in my projects it finds issues with the supporting libraries I am using and their associated type definitions.
I can change my code to have sound type definitions but I don't have an easy way to update all the other libraries I use. Does this effectively mean that I can't use strictNullCheck until/unless the libraries I am using update to be strict null safe?

Setting the option strictNullInputTypes to false disables strict null checks within Angular templates.
To enable StrictNullChecks open tsconfg. sys and add "strictNullChecks": true under the compilerOptions . With this set to true , you'll get a type error if you try to use null or undefined wherever Typescript expects a concrete type.
In Typescript to enforce strict null checks in tsconfig. json file, we need to enable “strictNullChecks” to true. When “strictNullChecks” is false, the language generally ignores variables of type null and undefined. If null and undefined is used in places where a definite value is expected, it raises an error.
After looking around for quite a while I finally found that by using the compiler option skipDefaultLibCheck you can get most of what I needed here.
