mcubed-lineup-insight-data

Description

This node module will retrieve fantasy sports data. In particular, this will aggregate data such as starting players, projected points, and recent performances for daily fantasy sports sites like DraftKings, FanDuel, and Yahoo.

mcubed-lineup-insight-data vs. mcubed-lineup-insight-server

mcubed-lineup-insight-server is a node module that relies on mcubed-lineup-insight-data for all of its data. The data module is used for retrieving the fantasy sports data from third-parties. The server module is used for aggregating the data for all the current contests and merging the data from the different third-parties into the contests.

Command Line Interface

This node module can be run from the command line using mcubed-lineup-insight-data -d PlayerInsight -c DraftKings -s NFL. The arguments for the command line interface are:

• -d / --data - Optional. Specifies the type of data to retrieve. This option is case-insensitive and should be on of the DataTypes. If this argument is omitted, then PlayerInsight is used as the default value.
• -c / --contestType - Required. Specifies the contest type to retrieve the data for. This option is case-insensitive and should be one of the ContestTypes.
• -s / --sport - Required for PlayerInsight and TeamInsight. Specifies the sport to retrieve the data for. This option is case-insensitive and should be one of the supported Sports.
• --contestID - Required for PlayerCard. Specifies the contest ID to get the player card for.
• --playerID - Required for PlayerCard. Specifies the player ID to get the player card for.

When run from the command line:

• The contest list request will produce an array of Contests written as a JSON formatted string to the standard output.
• The player card request will produce a PlayerCard object written as a JSON formatted string to the standard output.
• The player insight request will produce an array of Players written as a JSON formatted string to the standard output.
• The team insight request will produce an array of TeamInsights written as a JSON formatted string to the standard output.

Node Module Dependency

This node module can be used as a dependency of another node module. Run npm install mcubed-lineup-insight-data --save to add it as a dependency to your node module. An example usage of the module:

import insightData, * as interfaces from "mcubed-lineup-insight-data";

insightData.getPlayerInsight(interfaces.ContestType.DraftKings, interfaces.Sport.NFL).then((players) => {
    players.forEach((player) => {
        console.log(player.name);
    });
});

Error Handling

Whether using this module via the Command Line Interface or as a Node Module Dependency, the error handling will be the same. All errors thrown from this module will reject the promise that is returned from the InsightData class. The errors will always be of type Error. When running from the Command Line Interface, only the message property from the Error object will be written as a JSON formatted string to the standard error output. An example output of an error on the command line would look like:

{"message":"Could not retrieve data"}

API

InsightData

An instance of this class is returned when requiring mcubed-lineup-insight-data from within a node module.

• getContestList(contestType: ContestType, sport: Sport): Promise<Contest[]> - Returns a list of contests that are currently active for the DFS site. The contestType parameter is optional and should be a valid ContestType value. If no contestType is specified, then all contest types are returned. The sport parameter is optional and should be a valid Sport value. If no sport is specified, then all sports are returned. The return value is a promise that yields an array of Contests.
• getPlayerCard(contestType: ContestType, contestID: string, playerID: string): Promise<PlayerCard> - Returns an object containing specific information about a single player for a contest. The contestType parameter is required and should be a valid ContestType value. The contestID parameter is required and should be an ID from a contest object from the getContestList function. The playerID parameter is required and should be an ID from a player object nested within a contest object from the getContestList function. The return value is a promise that yields a PlayerCard.
• getPlayerInsight(contestType: ContestType, sport: Sport): Promise<Player[]> - Returns the data for a specified contest type and sport combination. The contestType parameter is required and should be a valid ContestType value. The sport parameter is required and should be a valid Sport value. The return value is a promise that yields an array of Players.
• getTeamInsight(contestType: ContestType, sport: Sport): Promise<TeamInsight[]> - Returns the team-specific data for a specified contest type and sport combination. The contestType parameter is required and should be a valid ContestType value. The sport parameter is required and should be a valid Sport value. The return value is a promise that yields an array of TeamInsights.

Player

Instances of this class are returned from calling the getPlayerInsight function from the InsightData object or serialized to JSON when using the command line interface.

• ID?: string - Optionally specifies a unique identifier for the player.
• injury?: PlayerInjury - Optionally specifies Injury information for the player.
• isStarter?: boolean - Optionally specifies if the player is in the starting lineup.
• mlbSpecific?: PlayerMLBSpecific - Optionally specifies the PlayerMLBSpecific identifying more information about the player. This data will only exists for players participating in MLB contests.

For instance, a RB may be eligible for the "RB" and the "RB/WR/TE" positions. This eligibility will be more reliable than the eligiblePlayerPositions from a Contest's ContestPosition. This occurs when DFS sites run unordinary contests such as tier-based RB positions where there is a RB Tier 1 and a RB Tier 2 position available. For both of these positions, the ContestPosition will return "RB" as an eligiblePlayerPosition. However, a player is likely only truly eligible for one of the two tiers. If a RB is only available for the RB Tier 1 position, this positionEligibility array will only contain "RB Tier 1".
• salary: number - Specifies how much the player costs for the contest.
• stats?: PlayerStats[] - Optionally specifies an array of PlayerStats associated with the player.
