This is an open source project that can be found at https://github.com/fantasy-football-league/sleeper-api-client.

NOTE: This package is in active development. Breaking changes can be made at any time.

import { Request, Response } from 'express';
import Sleeper from 'sleeper-api-client';

const sleeper = new Sleeper({
  leagueId: '<your-league-id-here>',
  draftId: '<your-draft-id-here>',
});

// Example using Express and Typescript
const getDraftById = async (req: Request, res: Response) => {
  // By default sleeper.getDrafts() will use the `draftId` from the options object
  // It can be overriden: `sleeper.getDrafts('<any-other-draft-id-here>')`
  const { status, data } = await sleeper.getDrafts();
  return res.status(status).json(data);
};

As of version 0.1.2 your leagueId and draftId can be included in an optional options object when instantiating a new Sleeper class.

All responses will return an object containing the status and data returned from the Sleeper API. Example responses below:

// Successful reponse
{
  status: 200,
  data: { ... },
}

// Error
{
  status: 400,
  data: {
    error: 'Bad Request',
    message: '...',
  }
}
