5 | | -## Why use this component? |
6 | | - |
7 | | -Let the code in Markdown run in real time, why is there such a need? |
8 | | - |
9 | | -In our front-end team, technical-related documents are written in Markdown. There are often a lot of sample code in the documentation. We hope that when you read the documentation, you can run the sample code to see the rendering interface. |
10 | | - |
11 | | -## What are the requirements? |
12 | | - |
13 | | -- Let the code in Markdown run and preview. |
14 | | -- The code can be edited online. |
15 | | -- Does not affect the layout of the entire document stream. |
16 | | -- Support React, support code highlighting. |
17 | | -- Babel can be configured. |
18 | | - |
19 | | -After understanding the requirements, I wrote a React component to satisfy these functions, [`react-code-view`](https://github.com/simonguo/react-code-view) , first look at the preview: |
| 3 | +Let the React code in Markdown be rendered to the page, and support online editing. |

23 | | -Preview: https://simonguo.github.io/react-code-view/ |
24 | | - |
25 | | -## Principle of implementation |
26 | | - |
27 | | -- Parse the Markdown document with `markdown-loader` and `html-loader`. |
28 | | -- Take the code out of the regular expression and give it to `codemirror` |
29 | | -- Compile the code in `codemirror` through babel and render it to the specified container via `ReactDOM.render` . |

31 | 7 | ## Install |
32 | 8 |
|
33 | 9 | ``` |
34 | 10 | npm install react-code-view |
35 | 11 | ``` |
36 | 12 |
|
37 | | -### Configure webpack . |
38 | | - |
39 | | -Support for `markdown-loader` needs to be added in webpack. Need to install: |
40 | | - |
41 | | -``` |
42 | | -npm install html-loader --save-dev |
43 | | -npm install [email protected] --save-dev |
44 | | -npm install [email protected] --save-dev |
45 | | -``` |
46 | | - |
47 | | -`webpack.config.js` |
| 13 | +### Configure Webpack |
48 | 14 |
|
49 | 15 | ```js |
| 16 | +// webpack.config.js |
| 17 | +export default { |
| 18 | + module: { |
| 19 | + rules: [ |
| 20 | + { |
| 21 | + test: /\.md$/, |
| 22 | + loader: 'react-code-view/webpack-md-loader' |
| 23 | + } |
| 24 | + ] |
| 25 | + } |
| 26 | +}; |
| 27 | +``` |
50 | 28 |
|
51 | | -const markdownRenderer = require('react-markdown-reader').renderer; |
| 29 | +#### Options |
52 | 30 |
|
53 | | -... |
| 31 | +```json |
54 | 32 | { |
55 | | - test: /\.md$/, |
56 | | - use: [{ |
57 | | - loader: 'html-loader' |
58 | | - }, { |
59 | | - loader: 'markdown-loader', |
60 | | - options: { |
61 | | - renderer: markdownRenderer(/**languages:Array<string>**/) |
62 | | - } |
63 | | - }] |
| 33 | + "parseLanguages": [ |
| 34 | + // Supported languages for highlight.js |
| 35 | + // default: "javascript", "bash", "xml", "css", "markdown", "less", "typescript" |
| 36 | + // See https://github.com/highlightjs/highlight.js/blob/main/SUPPORTED_LANGUAGES.md |
| 37 | + ], |
| 38 | + "htmlOptions": { |
| 39 | + // HTML Loader options |
| 40 | + // See https://github.com/webpack-contrib/html-loader#options |
| 41 | + }, |
| 42 | + "markedOptions": { |
| 43 | + // Pass options to marked |
| 44 | + // See https://marked.js.org/using_advanced#options |
| 45 | + } |
64 | 46 | } |
65 | 47 | ``` |
66 | 48 |
|
67 | | -languages 默认值：`["javascript", "bash", "xml", "css", "markdown", "less"]`; |
68 | | - |
69 | | -### Add Babel |
| 49 | +**webpack.config.js** |
70 | 50 |
|
71 | | -The sample code usually uses `ES2015+`, `React`, etc., and needs to compile the code in real time, so introduce `Babel` in `HTML`: |
| 51 | +```js |
72 | 52 |
|
73 | | -```html |
74 | | -<script |
75 | | - type="text/javascript" |
76 | | - src="//cdn.staticfile.org/babel-standalone/6.24.0/babel.min.js" |
77 | | -></script> |
| 53 | +export default { |
| 54 | + module: { |
| 55 | + rules: [ |
| 56 | + { |
| 57 | + test: /\.md$/, |
| 58 | + use:[ |
| 59 | + loader: 'react-code-view/webpack-md-loader', |
| 60 | + options:{ |
| 61 | + parseLanguages: ['typescript','rust'] |
| 62 | + } |
| 63 | + ] |
| 64 | + } |
| 65 | + ] |
| 66 | + } |
| 67 | +}; |
78 | 68 | ``` |
79 | 69 |
|
80 | | -> If `cdn.staticfile.org` is not well accessed in your area, you can change other CDN. |
