Cornelius

Cornelius provides a consistent interface for grabbing data from a number of Major League Baseball endpoints.

All of the data Cornelius returns is property of MLB Advanced Media, and subject to their usage terms.

Getting Started

Install Cornelius with npm install or yarn add:

yarn add cornelius

Import Cornelius into your project:

const connie = require('cornelius');

Usage

Cornelius' functionality is broken down into two core methods, player and team. Each method will return data determined by the action provided.

// Using the 'transactions' action, get all
// player transactions for the current month
connie.player('transactions')
  .then(data => console.log(data))
  .catch(error => console.log(error));

You can be more specific about the data you want, by providing an options object to Cornelius.

For example, the transactions action takes a start_date and end_date in YYYYMMDD format, to limit results to a specific period.

// Passing an options object, get all transactions between
// 1st May 2017, and 10th May 2017
connie.player('transactions', {start_date: '20170501', end_date: '20170510'})
  .then(data => console.log(data))
  .catch(error => console.log(error));

Option property names are deliberately generic, since they may be shared across different actions/methods.

Player Actions

'search'

• query String required - Search query e.g. 'Yoenis Cespedes'
• active Boolean true - Active or historic players flag

Search for a player by a given query.

'details'

• id String required - A player ID e.g. '493316'

role determines what to get stats for; 'hitting', 'pitching' or 'fielding'.

type determines the context of the stats; 'team', 'league' or 'career'.

team stats will break down stats across multiple teams if a player has moved team mid-season. league stats will do the same, splitting stats per league. career stats collates all of a player's stats regardless of team or league.
