Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

lxns-rhythm-api

v0.1.13

Published

A simple SDK for lxns api.

Readme

lxns-rhythm-api

npm

一个面向 落雪咖啡屋查分器 的 TypeScript SDK,当前支持 maimaichunithm

特性

  • 基于 ky 的轻量 HTTP 客户端。
  • 统一的 public / dev / personal 命名空间。
  • 完善的类型支持,根据是否传入 token 自动推断可用 API 类型。
  • 统一错误类型:LxnsApiError

安装

# npm
npm i lxns-rhythm-api

# pnpm
pnpm add lxns-rhythm-api

# yarn
yarn add lxns-rhythm-api

快速开始

import { LxnsApiClient } from "lxns-rhythm-api";

const client = new LxnsApiClient({
  devAccessToken: "<your-dev-token>",
  personalAccessToken: "<your-personal-token>",
});

// maimai public
const maimaiSong = await client.maimai.public.getSong(114);

// maimai dev
const maimaiPlayer = await client.maimai.dev.getPlayerByQQ(1234567890);

// chunithm public
const chunithmSong = await client.chunithm.public.getSong(1);

// chunithm personal
const me = await client.chunithm.personal.getPlayer();

配置

new LxnsApiClient({
  personalAccessToken?: string;
  devAccessToken?: string;
  baseURL?: string; // 默认: https://maimai.lxns.net/api/v0/
});
  • devAccessToken:启用 *.dev 命名空间。
  • personalAccessToken:启用 *.personal 命名空间。
  • baseURL:默认 https://maimai.lxns.net/api/v0/

资源接口

两个游戏命名空间都提供:

  • getAsset(type, id): Promise<Uint8Array>

示例:

const jacket = await client.maimai.getAsset("jacket", 114);
const icon = await client.chunithm.getAsset("icon", 1);

OAuth 流程

import { LxnsOAuthClient } from "lxns-rhythm-api";

const client = new LxnsOAuthClient({
  clientId: "<your-client-id>",
  redirectURI: "https://example.com/callback",
  clientSecret: "<your-client-secret>", // PKCE 可不传
});

// 1) 生成授权链接,跳转给用户
const authorizeURL = client.createAuthorizeURL({
  scope: ["read_user_profile", "read_player"],
  state: "nonce", // 可选
  codeChallenge: "<code-challenge>", // PKCE 可选
  codeChallengeMethod: "S256",
});

// 2) 回调拿到 code 后换 token
const token = await client.exchangeCodeForToken({
  code: "<auth-code>",
  codeVerifier: "<code-verifier>", // PKCE 模式传这个
});

// 3) 用 access_token 创建授权态客户端
const authorized = client.createAuthorizedClient(token.access_token);

// 4) 调用 OAuth 用户接口和 personal 接口
const profile = await authorized.user.getProfile();
const maimaiPlayer = await authorized.maimai.getPlayer();
const chunithmPlayer = await authorized.chunithm.getPlayer();

// 5) 刷新 token
const nextToken = await client.refreshAccessToken({
  refreshToken: token.refresh_token,
});

错误处理

SDK 会将 API 错误统一抛为 LxnsApiError

import {
  LxnsApiError,
  isAuthError,
  isNotFoundError,
  isRateLimitError,
  isServerError,
} from "lxns-rhythm-api";

try {
  await client.maimai.dev.getPlayer(1234567890);
} catch (error) {
  if (error instanceof LxnsApiError) {
    console.error(error.code, error.status, error.message);
  }

  if (isNotFoundError(error)) {
    // 404
  }
  if (isAuthError(error)) {
    // 401 / 403
  }
  if (isRateLimitError(error)) {
    // 429
  }
  if (isServerError(error)) {
    // >= 500
  }
}

导出

import {
  LxnsApiClient,
  LxnsOAuthClient,
  LxnsApiError,
  isLxnsApiError,
  MaimaiModels,
  ChunithmModels,
} from "lxns-rhythm-api";
