Quick Start

import { LPDBClient } from '@npldev/lpdb-ts-client'

const client = new LPDBClient({
  apiKey: 'your-api-key',
})

// Query players from Dota 2
const response = await client
  .endpoint('/player')
  .wiki('dota2')
  .conditions('[[nationality::France]]')
  .limit(10)
  .execute()

console.log(response.result)

Usage Examples

Get upcoming matches with stream URLs

const matches = await client
  .endpoint('/match')
  .wiki('counterstrike')
  .conditions('[[finished::0]]')
  .streamurls('true')
  .limit(5)
  .execute()

Get team information

const teams = await client
  .endpoint('/team')
  .wiki('leagueoflegends')
  .query('name, region, createdate')
  .order('createdate DESC')
  .limit(20)
  .execute()

Conditions Builder

Build complex query conditions with a fluent API:

import { ConditionsBuilder, Operator } from '@npldev/lpdb-ts-client'

const conditions = ConditionsBuilder.create('date', Operator.GREATER_THAN, '2024-01-01')
  .and('date', Operator.LESS_THAN, '2024-12-31')
  .andGroup(
    ConditionsBuilder.create('liquipediatier', Operator.EQUALS, '1').or(
      'liquipediatier',
      Operator.EQUALS,
      '2'
    )
  )
  .toString()

const tournaments = await client
  .endpoint('/tournament')
  .wiki('dota2')
  .conditions(conditions)
  .execute()

Error handling

import { LPDBClient, LPDBError } from '@npldev/lpdb-ts-client'

try {
  const response = await client.endpoint('/player').wiki('valorant').execute()
} catch (error) {
  if (error instanceof LPDBError) {
    console.error(`API Error (${error.status}):`, error.message)
  }
}
