Types for Typescript usage.

[cberthou]

Hello,

I writted custom types for typescript use of your module, but I'm not completely sure if they are ok. If anyone could check that, that would be nice.

This was made for external module definition. It should be defined as a namespace and exports and imports should be moved outside the namepace, but this works fine as an external definition.

declare module "memorystore" {
  import * as express from "express";
  import * as expressSession from "express-session";

  type memorystore = (session: SessionGenerator) => MemoryStoreConstructable;

  type SessionGenerator = (
    options?: expressSession.SessionOptions
  ) => express.RequestHandler;

  interface MemoryStoreConstructable {
    new (config?: MemoryStoreOptions): MemoryStore;
  }

  class MemoryStore extends expressSession.MemoryStore {
    public touch: (
      sid: string,
      session: Express.Session,
      callback: (err: any) => any
    ) => void;
  }

  interface MemoryStoreOptions {
    checkPeriod?: number;
    max?: number;
    ttl?: (
      options: any,
      session: Express.Session,
      sessionID: string
    ) => number | number;
    dispose?: (key: string, value: any) => void;
    stale?: boolean;
    serializer?: Serializer;
  }

  interface Serializer {
    stringify: (object: any) => string;
    parse: (value: string) => any;
  }

  const fun: memorystore;
  export = fun;
}

You need to ask this on stackoverflow

yeah, it'd be better ask there

Created a pull request for this: #17

Oh wait, sorry, #16 is already open to add types! Will close mine.

@roccomuso any chance of merging that one? I can confirm that the types are working.
