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

Document is Working in progress. Welcome to fork :)

Minimal form model that supports to validating and dirty-checking based on Mobx.

Most features are copied from Angular forms

npm install -S mobx-form-model

Examples

// Simple Controller
import FormController from 'mobx-form-model';

const ctrl = new FormController('', [
  ({ value }) =>
    value == null || !value.length ? { required: 'value required' } : undefined
]);

ctrl.valid; // false
ctrl.errors.required; // value required

ctrl.update('hello');
ctrl.valid; // true
ctrl.errors; // undefined
ctrl.dirty; // true
// nested controllers
import FormController, {
  FormControllerGroup,
  FormControllerArray
} from 'mobx-form-model';

const form = new FormControllerGroup({
  name: new FormController('Tom'),
  firstStep: new FormControllerGroup({
    gender: new FormController(1),
    birthday: new FormController('1990-01-01')
  }),
  questioins: new FormControllerArray([
    new FormController(),
    new FormController()
  ])
});

Controller vs Group vs Array

Shared

Properties

  • value,当前的值
  • valid, true 表示当前没有错误
  • dirty, 表示值是否变更过。
  • errors, 所有validator执行玩合并后的结果
  • enabled, 表示当前controller是否有效。false表示当前controller不会影响parent controllervaliddirty值。

以上这些属性都是 observable

Methods

  • disable()
  • enable()
  • markAsPristine() 将dirty设置为false,比如表单提交之前先检查dirty,用户没修改表单就无需重复提交,那在表单提交后调用 markAsPristine() 就可以避免重复提交已经提交的表单。

Change Controler's value

| | | | ----------------- | ------------------------------------------------------------ | | update(newValue) | 更新 value 标记 dirty 为 true 校验数据 | | replace(newValue) | 更新 value 标记 dirty 为 true 校验数据 | | reset(newValue) | 更新 value 标记 dirty 为 false 校验数据 |
