I only really needed ExpeditiousEngine, here are typings:

declare module 'expeditious' {
  export abstract class ExpeditiousEngine {
    public getNamespaceFromKey(key: string): string;
    public getKeyWithoutNamespace(key: string): string;
    public set(key: string, val: string, expire: number, callback: Function): void;
    public get(key: string, callback: Function): void;
    public del(key: string, callback: Function): void;
    public ttl(key: string, callback: Function): void
    public flush(ns: string, callback: Function): void;
  }
}

Also you might want to look into starting to use classes.

@SimonSchick great, appreciate this. Would you be willing to make a Pull Request with this?

[SimonSchick]

Not really, I'm kinda busy but still wanted to contribute this piece of code to you.

Are you sure? You have it 80% complete short of modifying package.json and pushing to a fork then clicking the PR button. I'll close this and add the typings in a few days if you don't open a PR 👍
