bets.js

Fixed odds bets library.

Installation

npm install bets --save

Usage

var bets = require('bets');

var b = bets();

b.lines()
  .set(1, {oddsNum: 1, oddsDen: 2}) // set line "1"
  .set({1: {...}, 2: {...}}) // set all lines
  .set([{...}, {...}]) // use an array instead
  .get(1) // get line "1"
  .get() // get all lines

b.wagers()
  .set(1, {lineIds: [1], amount: 5}); // set wager "1"
  .set({1: {...}, 2: {...}}); // set all wagers
  .set([{...}, {...}]); // use an array instead

b.wagers().totalRisk(); // get total risk
b.wagers().totalPayout(); // get total payout

b.wagers()
  .at(1) // select wager "1"
  .odds() // get its odds
  .amount(7) // change its amount
  .parts()
    .at(0)
    .lineId(2) // change its line id
    .lineId() // get its line id

b
  .lines()
    .set({...})
    .done() // finish with lines collection
  .wagers()
    .set({...})
    .done(); // finish with wagers collection

// place a parlay bet
b.wagers()
  .at(2)
  .type('parlay')
  .parts()
    .at(0).lineId(1).done()
    .at(1).lineId(2).done()
    .at(2).lineId(3).done()
    .done()
  .amount(20);

// use an object instead
b.wagers().set(2, {
  risk: 20,
  type: 'parlay',
  parts: [
    {lineId: 1},
    {lineId: 2},
    {lineId: 3},
  ]
});

Active/Inactive

Activate/deactivate wagers to alter the total risk/payout:

var b = bets();
b.lines().set(1, {oddsNum: 2, oddsDen: 1});
b.wagers().set(1, {risk: 10, lineIds: [1]});
b.wagers().set(2, {risk: 5, lineIds: [1]});
b.wagers.totalPayout(); // 30
b.wagers().at(2).active(false);
b.wagers.totalPayout(); // 20

Config

You can change property names of the underlying data (risk, oddsNum, oddsDen, lineIds, etc...). For example, changing risk to amount:

var bets = require('bets');
var conf = {wager: {risk: 'amount'}};

var b = bets(conf); // init config
b = bets().config(conf); // or do it later

b.wagers().at(1).risk(5);
b.wagers().get(); // {1: {amount: 5}}

b.wagers().set(1, {amount: 10});
b.wagers().at(1).risk(); // 10

Global

Declare a new global library with the config data of your choice.

var Bets = require('bets');

var bets = Bets
  .global()
  .config({line: {id: 'lineID'}})
  .config({wager: {risk: 'amount'}});
