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 🙏

特性

  • 封装认证以简化开发.
  • 异常处理
  • 使用 Halo rest api 更方便
  • 使用 TypeScript 编写,更明确的参数和返回值类型,更好的代码提示

管理后台 API 库

安装

使用 npm 方式安装示例如下:

npm install @halo-dev/admin-api --save

使用示例

以下是一个获取后台文章列表的简单示例:

import { AdminApiClient, HaloRestAPIClient } from "@halo-dev/admin-api";
//halo http 请求客户端.
const haloRestApiClient = new HaloRestAPIClient({
  baseUrl: process.env.HALO_BASE_URL,
  auth: { adminToken: "halo admin token" },
});
// 通过 haloRestApiCLient 创建 adminApiClient。
const haloAdminClient = new AdminApiClient(haloRestApiClient);
// 获取文章列表
haloAdminClient.post.list().then((res) => {
  console.log(res);
});

关于如何通过用户名和密码进行自动认证,这里提供了一个示例 example

由于 @halo-dev/admin-api 依赖 @halo-dev/rest-api-client,而其是基于 axios 进行 http 通信的,因此如果你有需要的话,可以使用 axios, 的拦截器对 halo api 的请求与响应进行一些处理。

import axios from "axios";

// Add a request interceptor
axios.interceptors.request.use(
  function (config) {
    // Do something before request is sent
    return config;
  },
  function (error) {
    // Do something with request error
    return Promise.reject(error);
  }
);

// Add a response interceptor
axios.interceptors.response.use(
  function (response) {
    // Any status code that lie within the range of 2xx cause this function to trigger
    // Do something with response data
    return response;
  },
  function (error) {
    // Any status codes that falls outside the range of 2xx cause this function to trigger
    // Do something with response error
    return Promise.reject(error);
  }
);

@halo-dev/content-api 也可以这样使用拦截器。

前台 API 库

使用 npm 安装示例如下:

npm install @halo-dev/content-api --save

使用示例

同样我们使用一个获取博客前台文章列表的示例如下:

import { ContentApiClient, HaloRestAPIClient } from "@halo-dev/content-api";
// 创建 halo http 请求客户端
const haloRestApiClient = new HaloRestAPIClient({
  baseUrl: process.env.HALO_BASE_URL,
  auth: { apiToken: process.env.HALO_API_TOKEN },
});
// 通过 http 客户端创建 halo 前台 api 客户端
const haloContentClient = new ContentApiClient(haloRestApiClient);
// 获取文章列表
haloContentClient.post.list().then((res) => {
  console.log(res);
});

Halo Rest API Http 通信库

安装

你可以使用 npm 安装它,示例如下:

npm install @halo-dev/rest-api-client

使用 requireimport 导入

// CommonJS
const { HaloRestAPIClient } = require("@halo-dev/rest-api-client");
// ES modules
import { HaloRestAPIClient } from "@halo-dev/rest-api-client";

使用示例

const client = new HaloRestAPIClient({
  baseUrl: "https://example.halo.run",
  // Use password authentication
  auth: {
    username: process.env.HALO_USERNAME,
    password: process.env.HALO_PASSWORD,
  },
});

auth 参数为认证方式,支持以下几种认证方式,示例如下:

  1. 使用 API token 认证,它适用于 halo 博客前台 api 认证
auth: {
  apiToken: process.env.HALO_API_TOKEN;
}
  1. 使用 Admin token 认证,它适用于 halo 后台管理 api 认证
auth: {
  adminToken: process.env.HALO_ADMIN_TOKEN;
}
  1. 使用自定义请求头认证方式
auth: {
    type: "customizeAuth",
    authHeader: "Admin-Authorization",
      getToken () {
      return localStorage.getItem ("Access_Token")
    }
}
  1. 使用 OAuth2 Bearer token 的认证方式,最终会在请求头添加 Authorization: bearer some-token
auth: {
  oAuthToken: process.env.HALO_OAUTH_TOKEN;
}

Basic 认证

会在请求头添加例如 Authorization: Basic dXNlci1jbGllbi1zZWNyZXQtODg4OA== 这样的 pair

const client = new HaloRestAPIClient({
  baseUrl: "https://example.halo.run",
  // Use basic authentication
  basicAuth: { username: "user", password: "password" },
});

另外还支持通过提供一个 TokenProvider 来接管 halo 的认证,这样不需要在考虑如何实现登录和 token 过期怎么续期的逻辑,示例如下:

import {
  HaloRestAPIClient,
  LocalStorageTokenStore,
  // FileTokenStore,
  // TokenStore,
  DefaultTokenProvider,
} from "@halo-dev/rest-clint-api";

// Use LocalStorageTokenStore to persistence AccessToken to localStorage (in browser only)
//you can use FileTokenStore if in the Node environment.
// If there is no suitable Token store implemention, you can implement your own token storage strategy through the TokenStore interface.
const localStorageTokenStore = new LocalStorageTokenStore();

//halo api base url.
const baseUrl = process.env.VUE_APP_BASE_URL;

const haloRestApiClient = new HaloRestAPIClient({
  baseUrl: baseUrl,
});

const buildTokenProvider = (credentials) => {
  return new DefaultTokenProvider(
    {
      ...credentials,
    },
    baseUrl,
    localStorageTokenStore
  );
};

const tokenProvider = buildTokenProvider({
  username: "your halo username",
  password: "your password",
});
haloRestApiClient.setTokenProvider(tokenProvider);
//now you can use haloRestApiClient to build your api client

完整的例子可以点 这里

发送 Http 请求

const haloRestApiClient = new HaloRestAPIClient({
  baseUrl: "https://example.halo.run",
  basicAuth: { username: "user", password: "password" },
});
//build http client to perform http request
const client = haloRestApiClient.buildHttpClient();

//api parameters
const parameters = {};
//http get
client.get("https://example.halo.run", parameters);
//http post
client.post("https://example.halo.run", parameters);

Logger 日志库

安装

使用 npm 安装示例如下:

npm install @halo-dev/logger --save

主要概念

@halo-dev/logger 包支持按从最详细到最不详细的顺序指定的以下日志级别:

  • debug
  • info
  • warning
  • error

当以编程方式或通过 HALO_LOG_LEVEL 环境变量设置日志级别时,使用小于或等于您选择的日志级别时写入的任何日志都将被显示。

例如,将日志级别设置为 warning 将导致所有日志级别为 warningerror 的日志被显示。

使用示例

示例 1 - 基本使用

import * as Logger from "@halo-dev/logger";
Logger.setLogLevel ("info");

//operations will now emit info, warning, and error logs

//create a namespaced logger
const logger = Logger.createClientLogger ("posts");
const client = new AdminApiClient (/* params */);
client.post.list ()
  .then (res => {
    /* write an info log */
    logger.info ("Successfully acquired a list of articles", res);
  })
  .catch (e => { /* do work */ });
});

示例 2 - 覆盖原先日志输出方式

import { HaloLogger, setLogLevel } from "@halo-dev/logger";

setLogLevel("warning");

//override logging to output to console.log (default location is stderr)
HaloLogger.log = (...args) => {
  console.log(...args);
};
HaloLogger.log("hello world!");
