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 🙏

一站式中后台表单解决方案

官网

https://xrender.fun/form-render

FormRender 1.0 是下一代的 React.js 表单解决方案。项目从内核级别进行了重写,为了能切实承接日益复杂的表单场景需求。我们的目标是以强大的扩展能力对表单场景 100%的覆盖支持,同时保持开发者能快速上手,并以表单编辑器、插件、自定义组件等一系列周边产品带来极致的开发体验。在开发 1.0 的道路上,我们做了一系列的取舍,详见0.x - 1.0 迁移文档

安装

FormRender 依赖 ant design,单独使用不要忘记同时安装 antd

npm i form-render --save

使用

最简使用 demo:

import React from 'react';
import { Button } from 'antd';
import FormRender, { connectForm } from 'form-render';

const schema = {
  type: 'object',
  properties: {
    input1: {
      title: '简单输入框',
      type: 'string',
      required: true,
    },
    select1: {
      title: '单选',
      type: 'string',
      enum: ['a', 'b', 'c'],
      enumNames: ['早', '中', '晚'],
    },
  },
};

class Demo extends React.Component {
  render() {
    const { form } = this.props;
    return (
      <div>
        <FormRender form={form} schema={schema} />
        <Button type="primary" onClick={form.submit}>
          提交
        </Button>
      </div>
    );
  }
}

export default connectForm(Demo);

对于函数组件,FormRender 提供了 useForm hooks, 书写更为灵活

import React from 'react';
import { Button } from 'antd';
import FormRender, { useForm } from 'form-render';

const schema = {
  type: 'object',
  properties: {
    input1: {
      title: '简单输入框',
      type: 'string',
      required: true,
    },
    select1: {
      title: '单选',
      type: 'string',
      enum: ['a', 'b', 'c'],
      enumNames: ['早', '中', '晚'],
    },
  },
};

const Demo = () => {
  const form = useForm();
  return (
    <div>
      <FormRender form={form} schema={schema} />
      <Button type="primary" onClick={form.submit}>
        提交
      </Button>
    </div>
  );
};

export default Demo;

从 demo 中我们不难发现 FormRender 的一些设计:

  1. 以 schema 来描述表单展示,提交方式与 antd v4 的方式类似
  2. schema 以国际标准的 JSON schema 为基础,同时能够方便使用任何 antd 的 props
  3. 通过 bind 字段,我们允许数据的双向绑定,数据展示和真实提交的数据可以根据开发需求不同(例如从服务端接口拿到不规则数据时,也能直接使用)
  4. 可以通过displayType,labelWidth等字段轻易修改展示

组件 Props

import Form, { useForm, connectForm } from 'form-render';

<Form /> (常用 props)

| 参数 | 描述 | 类型 | 是否必填 | 默认值 | | ------------ | ------------------------------------------------------------------------------ | ----------------------------------------------- | ----------------- | -------- | -------- | | schema | 描述表单的 schema,详见 | object | 是 | | | form | useForm创建的表单实例,与 Form 一对一绑定 | FormInstance | 是 | | | onFinish | 提交后的回调,执行 form.submit() 后触发 | (formData, errorFields: Error[]) => void | 否 | () => {} | | beforeFinish | 在 onFinish 前触发,一般用于外部校验逻辑的回填,入参是个对象,便于扩展 | ({ data, errors, schema, ...rest }) => Error[] | Promise<Error[]> | 否 | () => {} | | displayType | 表单元素与 label 同行 or 分两行展示, inline 则整个展示自然顺排 | string('column' / 'row' / 'inline') | 否 | 'column' | | widgets | 自定义组件,当内置组件无法满足时使用 | object | 否 | {} | | watch | 类似于 vue 的 watch 的用法,详见表单监听 & 回调 | object | 否 | {} |

注 1:

<Form /> (不常用 props)

| 参数 | 描述 | 类型 | 默认值 | | ---------------- | ---------------------------------------------------------------- | ------------------- | ------ | | column | 一行展示多少列 | number | 1 | | mapping | schema 与组件的映射关系表,当内置的表不满足时使用 | object | {} | | debug | 开启 debug 模式,时时显示表单内部状态 | boolean | false | | debugCss | 用于 css 问题的调整,显示 css 布局提示线 | boolean | false | | locale | 展示语言,目前只支持中文、英文 | string('cn'/'en') | 'cn' | | configProvider | antd 的 configProvider,配置透传 | object | - | | debounceInput | 是否开启输入时使用快照模式。仅建议在表单巨大且表达式非常多时开启 | boolean | false | | validateMessages | 修改默认的校验提示信息。详见下 | object | {} |

validateMessages

Form 为验证提供了默认的错误提示信息,你可以通过配置 validateMessages 属性,修改对应的提示模板。一种常见的使用方式,是配置国际化提示信息:

const validateMessages = {
  required: '${title}是必选字段',
  // ...
};

<Form validateMessages={validateMessages} />;

目前可以用的转义字段为 ${title}/${min}/${max}/${len}/${pattern}, 如果有更多需求请提 issue

useForm / connectForm

useForm / connectForm 用于创建表单实例,所有对表单的外部操作和回调函数全挂在其生产的实例上,例如表单提交是 form.submit。注意 useForm 是 hooks,而 connectForm 是高阶组件,所以前者只能在函数组件使用,后者可用于 class 组件。两者无其他区别。使用时需要创建实例,并通过 props 挂钩到与其对应的表单上:

import Form, { useForm } from 'form-render';

const Demo = () => {
  const form = useForm();
  return <Form form={form} schema={...} />;
};
import Form, { connectForm } from 'form-render';

const Demo = ({ form }) => {
  return <Form form={form} schema={...} />;
};

export default connectForm(Demo);

form 方法

| 参数 | 描述 | 类型 | | ---------------- | --------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------- | ----------------- | | submit | 触发提交流程,一般在提交按钮上使用 | () => void | | resetFields | 清空表单(也会清空一些内置状态,例如校验) | ({formData?: any, submitData?: any, errorFields?: Error[], touchedKeys?: any[], allTouched?: boolean}) => void | | errorFields | 表单校验错误的数组 | array,[{name, error: []}] | | setErrorFields | 外部手动修改 errorFields 校验信息,用于外部校验回填 | (error: Error | Error[]) => void | | setValues | 外部手动修改 formData,用于已填写的表单的数据回填 | (formData: any) => void | | onItemChange | 外部修改指定单个 field 的数据 | (path: string, value: any) => void | | getValues | 获取表单内部维护的数据 formData | () => void | | schema | 表单的 schema | object | | touchedKeys | 已经触碰过的 field 的数据路径 | string[] | | removeErrorField | 外部手动删除某一个 path 下所有的校验信息 | (path: string) => void | | formData | 表单内部维护的数据,建议使用 getValues/setValues | object |
