toy stock market client

A common API for interacting with the HTTP interface of toy-stock-market.

Works on both a browser and node.js, given you provide it implementations of the fetch API, EventSource and EventEmitter.

Used by toy-stock-market-ui (browser) and toy-stock-market-bot (node.js).

API

the default exported symbol is a function expecting an object defining:

• fetch
• EventEmitter
• EventSource
• prefix

this in turn returns the TSM client API, which consists of:

{
  // TRADER AUTH
  isLoggedIn = (): ?string
  register = (user: string, pass: string, money: number): Promise<string>
  login = (user: string, pass: string): Promise<string>
  logout = (): Promise<void>

  // TRADER GETTERS
  trader = (): Promise<TraderWoPass>

  // TRADER ACTIONS
  bid = (stockName: string, price: number, quantity: number): Promise<void>
  ask = (stockName: string, price: number, quantity: number): Promise<void>

  // OPEN ENDPOINTS
  stocks = (): Promise<Array<string>>
  stockLOB = (stockName: string): Promise<StockLOB>
  transactions = (): Promise<Array<Transaction>>
  stats = (): Promise<Stats>

  // STREAM EVENTS
  stockEventEmitter:EventEmitter
}
