Quickstart

Links: create your client here ​ / ​ get your api key here

Quick Links: v2 - client auth ​ / ​ v2 - lazer auth ​ / ​ v2 - cli auth ​ / ​ v2 - Discord Verify ​ / ​ v2 - Website login ​ / ​ v1 usage ​ / ​ v2 - prevent throw errors


Client Auth

import { auth } from 'osu-api-extended';


async function main() {
  try {
    await auth.login({
      type: 'v2',
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
      cachedTokenPath: './client.json' // path to the file your auth token will be saved (to prevent osu!api spam)
    });

    const result = await v2.users.details({ user: 'mrekk', mode: 'osu', key: '@' });
    if (result.error != null) {
      console.log(result.error);
      return;
    };


    console.log(result);
  } catch (error) {
    console.log(error);
  };
};

main();

Lazer Auth

Authorization though your account

import { auth } from 'osu-api-extended';


async function main() {
  try {
    await auth.login({
      type: 'v2',
      login: LOGIN,
      password: PASSWORD,
      cachedTokenPath: './lazer.json' // path to the file your auth token will be saved (to prevent osu!api spam)
    });

    const result = await v2.me.details();
    if (result.error != null) {
      console.log(result.error);
      return;
    };


    console.log(result);
  } catch (error) {
    console.log(error);
  };
};

main();

CLI Auth

import { auth } from 'osu-api-extended';


async function main() {
  try {
    await auth.login({
      type: 'cli',
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
      redirect_url: REDIRECT_URL,
      scopes: ['public'],
      cachedTokenPath: './cli.json' // path to the file your auth token will be saved (to prevent osu!api spam)
    });

    const result = await v2.me.details();
    if (result.error != null) {
      console.log(result.error);
      return;
    };


    console.log(result);
  } catch (error) {
    console.log(error);
  };
};

main();

Discord Verify

import { Client } from 'discord.js';
import { auth } from 'osu-api-extended';

const discord_bot = new Client({ intents: [GatewayIntentBits.Guilds, GatewayIntentBits.MessageContent, GatewayIntentBits.GuildMessages] }); // no clue why i need those intents


// send this link to user
discord_bot.on('messageCreate', async message => {
  if (message.author.bot) return;
  if (!message.content.startsWith('!')) return;

  const [command, value1, value2] = message.content.split('!').join('').split(' ');
  logger('command', { _c: 'yellowBright', v: command }, value1, value2);

  if (command == 'verify') {
    const url = const url = auth.build_url({
      client_id: CLIENT_ID,
      redirect_url: REDIRECT_URL,
      scopes: ['identify'],
      state: message.author.id
    });


    message.reply(`Verify via this link: ${url}`);
    return;
  };
});



// somewhere else verify this
function verifyUser(code, state) {
  // it returns user object
  const verify = await auth.authorize({
    code: code,
    client_id: CLIENT_ID,
    client_secret: CLIENT_SECRET,
    redirect_url: REDIRECT_URL
  });


  console.log(verify);
};

Website login

Nitro framework example

import { auth } from 'osu-api-extended';


// /auth page
export default defineEventHandler(event => {
  const build_url = auth.build_url({
    client_id: CLIENT_ID,
    redirect_uri: REDIRECT_URL,
    scopes: ['identify'],
  });


  return sendRedirect(event, build_url);
});


// /callback page
export default defineEventHandler(async event => {
  const { code } = getQuery(event);
  const verify = await auth.authorize({
    code: code.toString(),

    client_id: CLIENT_ID,
    client_secret: CLIENT_SECRET,
    redirect_url: REDIRECT_URL,
  });


  setCookie(event, 'user_id', verify.id.toString());
  setCookie(event, 'user_name', verify.username.toString());

  setCookie(event, 'access_token', verify.access_token);
  setCookie(event, 'refresh_token', verify.refresh_token);


  return sendRedirect(event, '/');
});

V1 usage

import { auth, v1 } from 'osu-api-extended';


async function main() {
  try {
    auth.login({
      type: 'v1',
      api_key: API_KEY,
    });


    const beatmap = await v1.beatmap.diff(3798013);
    console.log(beatmap);
    
  } catch (error) {
    console.log(error);
  };
};

main();

Prevent throw errors

import { auth } from 'osu-api-extended';

auth.settings.throwErrors = false;


async function main() {
  try {
    await auth.login({
      type: 'v2',
      client_id: CLIENT_ID,
      client_secret: CLIENT_SECRET,
    });

    const result = await v2.beatmaps.events.list({ types: ['approve'] });
    if (result.error instanceof Error) {
    // or
    if (result.error != null) {
      console.log(result.error);
