【Rollup】自定义组件 - 文章渲染组件

前言

利用 Rollup 构建一个文章展示抽屉SDK，用来记录前端自定义SDK的过程

工程实践

初始化

创建项目

mkdir packageName 
npm init -y

Typescript功能初始化

npm install typescript -D

npx tsc -init

创建 rollup.config.js

import typescript from 'rollup-plugin-typescript2';
import less from 'rollup-plugin-less';
import clear from 'rollup-plugin-clear';
export default {
  input: ['./src/index.ts'],
  output: [
    {
      file: './lib/umd/index.js',
      name: 'DumboUI',
      format: 'umd',
      sourcemap: true,
    },
    {
      file: './lib/esm/index.js',
      format: 'es',
      sourcemap: true,
    },
  ],
  plugins: [
    typescript(), // 会自动读取 文件tsconfig.json配置
    less({ output: './lib/index.less' }),
    clear({
      targets: ['lib'],
    }),
  ],
  external: ['react', 'react-dom'],
};

添加插件依赖包

npm install rollup-plugin-typescript2 rollup-plugin-less rollup-plugin-clear -D

package.json 添加dev脚本

 "scripts": {
    "dev": "rollup -c rollup.config.js -w"
 }

业务开发

安装 React 必需依赖包

npm install react react-dom
npm install @types/react @types/react-dom  -D

编写组件代码

参考文章最后业务代码

本地开发调试

sdk项目包执行

sudo npm link

业务项目执行

npm link @levenx/grouper

执行打包命令

npm run build

发布npm包

Npm登陆

npm login

设置好username, password,email

Npm发布

npm publish

SDK使用步骤

引入 sdk 依赖

这个包已经成功上传，感兴趣的可以尝试使用下

npm install @levenx/grouper

sdk使用

import Grouper from '@dumbo/grouper';

const docs = new Grouper();
// 展示
docs.render({title:'title',content:'content'})

业务代码

入口 index.tsx

import React from 'react';
import ReactDOM from 'react-dom';
import Preview from '@/components/preview';

export interface GrouperDocConfig {
    root?: HTMLElement;
    title?: string;
    content?: string;
}

export default class GrouperDoc {

    config;

    root;

    constructor(config: GrouperDocConfig) {
        this.config = config;
    }

    destory() {
        ReactDOM.unmountComponentAtNode(this.root);
    }

    render(config: GrouperDocConfig) {
        const { title, content, root } = config;
        let div = root;
        if (!root) {
            div = document.createElement('div');
            document.body.appendChild(div);
        }
        this.root = div;
        const App = <Preview onClose={this.destory.bind(this)} title={title} content={content} />;
        ReactDOM.render(App, div)
    }

}

// components/preview/index.tsx

import React, { useState, useEffect, useMemo } from 'react';
import classnames from 'classnames';
import { marked } from 'marked';
import './index.less';

interface PreviewProps {
    onClose: () => void;
    title: string;
    content: string;
}

export default function Preview(props: PreviewProps) {
    const { onClose, title, content } = props;
    const [visible, setVisible] = useState(false);

    useEffect(() => {
        setTimeout(() => {
            setVisible(true);
        }, 0);
    }, [])

    const article = useMemo(() => {
        return marked(content)
    }, [content]);

    return (
        <div className={classnames("grouper-preview", { "grouper-preview--visible": visible })}>
            <div className="grouper-preview__title">

                    }, 300);
                }}>x</span>
            </div>
