Development

Installing

After cloning the repository, install dependencies with

npm install

Then, build with

Project Structure

src contains all the project code not used for testing. Compiled typescript definitions end up in the project root directory because that's where they need to be in order for them to be accessable when this package is installed with npm.

src/GameDataInterface.ts is what NovaJS expects all file readers to implement. It has a member ids: Promise<NovaIDs>, which resolves to an object that has a list of available ids for each NovaJS data type (such as Ship or SpriteSheet). It also has as a member a NovaDataInterface, which is where the NovaJS data types are aggregated. These data types are defined in src/.

For each data type, NovaDataInterface has a corresponding Gettable, which is an object used for asynchronously requesting instances of that data type. A Gettable<T> is initialized with a function of type (id: string) => Promise<T>, which it uses to fulfill requests made to it via its .get(id: string): Promise<T> method. An implementation of Gettable that caches every requested item is provided, but need not be used, and a different implementation may be used as long as it conforms to the same type.

See NovaParse (typescript branch) for NovaJS's Nova File parser, which implements this interface.
