Component and Service developement is done by making an Angular project where you write your component or service in typescript
On github there is a NG1 to TiNG example that has a "master" branch that just has the NG1 example and the "ting" branch has the TiNG example with some documentation what is what and how to convert.
The specification what a component or service has (properties that can be set, api's that can be called, or events (handlers) that a component can trigger) are defined in a spec
What types can be used for the properties on the model of the component or service are described here, those properties can have tags to give them a bit more configuration how they are used in developer or at runtime
