如何将 myst-parser 用于 SharePoint Web 部件？

Question

我尝试将 myst-parser 作为 SharePoint WebPart 的外部 JavaScript 库包含在内，如下

https://learn.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/guidance/use-existing-javascript-libraries#reference-existing-libraries-as-external-resources

  "externals": {
    "myst-parser": {
      "path": "https://cdn.jsdelivr.net/npm/[email protected]/dist/myst.min.js",
      "globalName": "myst-parser"
    }
  },

在我的网络部件中：

import * as myst from 'myst-parser';
const html = myst.mystParse('# Hello to the world!')

我能够为 Web 部件提供服务器。然而，它显示

如何在sharepoint web部件中使用unified.js？

Answer 1

我不得不降级 Unified 版本并调整 gulpfile.js 以包含自定义 Webpack 配置。

package.json的内容：

{
  "name": "component-webpart",
  "version": "0.0.1",
  "private": true,
  "engines": {
    "node": ">=16.13.0 <17.0.0 || >=18.17.1 <19.0.0"
  },

    "test": "gulp test"
  },

    "@microsoft/sp-module-interfaces": "1.18.2",
    "@rushstack/eslint-config": "2.5.1",
    "@types/marked": "^6.0.0",

    "gulp": "4.0.2",
    "typescript": "5.3.3",
    "webpack": "5.89.0"
  }
}

gulpfile.js 的内容：

'use strict';

const build = require('@microsoft/sp-build-web');


build.addSuppression(`Warning - [sass] The local CSS class 'ms-Grid' is not camelCase and will not be type-safe.`);

var getTasks = build.rig.getTasks;
build.rig.getTasks = function () {
  var result = getTasks.call(build.rig);

  result.set('serve', result.get('serve-deprecated'));

  return result;
};


build.configureWebpack.mergeConfig({
  additionalConfiguration: (generatedConfiguration) => {
    generatedConfiguration.module.rules.push(
      {
        resolve: {
          alias: {   
            'myst-parser': 'myst-parser/dist',                      
            'myst-common': 'myst-common/dist',
            'myst-directives': 'myst-directives/dist',
            'myst-frontmatter': 'myst-frontmatter/dist',
            'myst-roles': 'myst-roles/dist',
            'myst-spec': 'myst-spec/dist',
            'myst-spec-ext': 'myst-spec-ext/dist',
            'myst-to-html': 'myst-to-html/dist',
            'myst-transforms': 'myst-transforms/dist',
            'markdown-it-amsmath': 'markdown-it-amsmath/dist',           
            'markdown-it-dollarmath': 'markdown-it-dollarmath/dist',           
            'markdown-it-myst': 'markdown-it-myst/dist',
            'markdown-it-myst-extras': 'markdown-it-myst-extras/dist',   
          },
        },
      }
    );

    return generatedConfiguration;
  }
});

build.initialize(require('gulp'));

使用示例：

import {unified} from 'unified';
import { mystParser } from 'myst-parser';
import { State, transform, mystToHast, formatHtml  } from 'myst-to-html';
import rehypeStringify from 'rehype-stringify';

//...

let htmlString = '!! Could not render markdown content with MyST !!:\n' + markdownContent;

  try{
    const pipe = unified()
    .use(mystParser)
    .use(transform, new State())     
    .use(mystToHast)
    .use(formatHtml)
    .use(rehypeStringify);

    const result = pipe.processSync(markdownContentWithLinks);
    htmlString = result.value;   
  } catch(error){
    console.log('Could not render markdown content with MyST!', error);
  }    

  return (   
    <div 
      className={styles.component}
      title={extraSearchTerms}       
      data-source={url} 
    >   
    <div
     dangerouslySetInnerHTML={{__html:htmlString}}
    >
    </div>      
    </div>      
  );
