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 🙏

Readme

umi-plugin-mst

针对 MobXumi 插件,需要 umi 3.0 及以上(>= 3.0.0)版本

提供 dva 之外的另一种选择。

umi-plugin-mst 内置:

可以和 @umijs/plugin-dva, @umijs/plugin-model 一起使用。

models/目录下同时存在三种类型(dva、hooks、mobx)的 model 时,不会冲突。

安装

在 umi 工程根目录下 使用 yarn 安装:

yarn add umi-plugin-mst --dev

使用

示例工程:example

目录规约

一个基础的 umi 项目目录结构:

├── package.json
└── src
+   ├── models
+       └── foo.ts
    ├── pages
        └── index.tsx
    └── app.ts

models/ 目录下有 types.model 时启用 umi-plugin-mst:

/**
 * @file src/models/foo.js
 */
import { types } from 'mobx-state-tree';

const Foo = types
  .model({
    bar: types.optional(types.string, ''),
  })
  .actions((self) => ({
    setBar(text: string) {
      self.bar = text;
    },
    clearBar() {
      self.bar = '';
    },
  }));

export default Foo.create({});

使用 Hooks 连接数据到视图:

/**
 * @file src/pages/index.js
 */
import React from 'react';
import { useMst, observer } from 'umi';

function Index(): JSX.Element {
  const { foo } = useMst();
  return (
    <div>
      record: {JSON.stringify(foo)}
      <input value={foo.bar} onChange={(event) => foo.setBar(event.target.value)} />
      <button onClick={foo.clearBar}>Clear</button>
    </div>
  );
}

export default observer(Index);

使用 Decorator 连接数据到视图:

/**
 * @file src/pages/home.js
 */
import React, { Component } from 'react';
import { Instance } from 'mobx-state-tree';
import { observer, inject } from 'umi';
import foo from '@/models/foo';

type FooInstance = Instance<typeof foo>;

interface IHomeProps {
  foo: FooInstance;
}

@inject('foo')
@observer
export default class Home extends Component<IHomeProps> {
  render(): JSX.Element {
    const foo = this.props.foo;
    return (
      <div>
        record: {JSON.stringify(foo)}
        <input value={foo.bar} onChange={(event) => foo.setBar(event.target.value)} />
        <button onClick={foo.clearBar}>Clear</button>
      </div>
    );
  }
}
