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 🙏

event router

Readme

event-router

event-router 是 api 模仿 koa 的方式,旨在解决进程中路由管理混乱的问题。API 和 Electron 中的 ipcMain 与 ipcRenderer 类似。

安装

npm i @linzb93/event-router

服务端使用

import { createServer } from "@linzb93/event-router";
// 以Electron的ipcMain为例
import { ipcMain } from "electron";
const app = createServer({
  handle(name: string, callback: Function) {
    return ipcMain.handle(name, async (_, dataStr) => {
      return await callback(JSON.parse(dataStr));
    });
  },
});

app.handle("user-get", async (request) => await getListFromDatabase(request));

Route

像 koa 一样,为了方便管理,可以为相同路径前缀的监听器创建一个Route子模块。

import { Route } from "@linzb93/event-router";

const router = Route();
router.handle(
  "user-get",
  async (request) => await getListFromDatabase(request)
);
app.use("api", router);

中间件

中间件可以在路由处理程序之前和之后处理逻辑,支持异步调用。

import { Route } from "@linzb93/event-router";
import dayjs from "dayjs";

app.use(async (ctx, next) => {
  console.log(
    `route: ${ctx.path}, time: ${dayjs().format("YYYY-MM-DD HH:mm:ss")}`
  );
  await next();
  console.log("response sent");
});

错误处理

event-router虽然有内置的全局错误处理,但是也可以自定义全局错误处理,或者单个Route模块下的错误处理。

// 全局错误处理
app.catch((path, error) => {
  console.log(`${path}错误:${error.message}`);
});

渲染进程使用

以 Electron 的 ipcRenderer 为例。

import { createClient } from "@linzb93/event-router";
(async () => {
  const request = createClient({
    invoke(name, data) {
      return window.ipcRenderer.invoke(name, JSON.stringify(data));
    },
  });
  const users = await request("api-user-get", {
    age: 30,
  });
  console.log(users);
})();
