Yahoo Fantasy Query Builders for Go

Installation

go get github.com/famendola1/yfquery

Yahoo Endpoints

The Yahoo offical documentation for their Fantasy Sports API is not comprehensive and incomplete, despite being the offical. For a more complete overview of the supported endpoints, see the README.

Before You Start

The functionality of this package require the use of a *http.Client that is configured for the Yahoo Fantasy API endpoint. You can use the github.com/famendola1/yauth package to configure a *http.Client to use.

Query Builders

The query buiilders were designed to be able to easily generate queries for all the Yahoo Fantasy API endpoints. The builders expose functions that add pieces and parameters to the query. They also expose the following functions:

• ToString: Builds the string for the query that the builder represents.
• Get: Sends a GET request to the Yahoo Fantasy API for the endpoint that the query represents. A successful query will return a FantasyContent struct.
• Post: Sends a POST request to the Yahoo Fantasy API for the endpoint that the query represents. A successful query will return a FantasyContent struct.
• Put: Sends a PUT request to the Yahoo Fantasy API for the endpoint that the query represents. A successful query will return a FantasyContent struct.
• Delete: Sends a DELETE request to the Yahoo Fantasy API for the endpoint that the query represents. A successful query will return a FantasyContent struct.
• Reset: Clears all query parameters and the payload of the query. If Reset is called on a chained query builder (i.e. Transactions in League().Key("key").Transactions()), only the data on the chained query builder is cleared.

WARNING: The query builders do not validate that the queries they build are valid Yahoo endpoints.
