Is this still open? In case, I would like to help :) However, since it would be my first contribution, can you give me some more guidance?

@nicdard yup and that would be great!

1. Create a basic wrapped MappedTypeNode in this directory: https://github.com/dsherret/ts-morph/tree/latest/packages/ts-morph/src/compiler/ast/type (base should be TypedNode... see here for the typescript AST node: https://github.com/dsherret/ts-morph/blob/1dc592141432f8e0541b7b6211f7edf8ad205e5a/packages/common/lib/typescript.d.ts#L947)
2. Update https://github.com/dsherret/ts-morph/blob/latest/packages/ts-morph/src/factories/kindToWrapperMappings.ts to have the mapping from ts.SyntaxKind.MappedType to MappedTypeNode.
3. Run yarn code-generate in packages/ts-morph. This will generate a lot of the code for you.
4. Start adding helper methods and write tests for these methods similar to how the other nodes are done.

Maybe just start with methods for navigation then after if you would like you can do methods for manipulating the text.
