As a website operator proficient in the Anqi CMS content management system and with a keen perception of user needs, I am delighted to elaborate on how the Anqi CMS Markdown editor supports the display of mathematical formulas and flowcharts.AnQi CMS is committed to providing users with an efficient and flexible content management experience, fully aware of the importance of precise expression of mathematical formulas and clear display of flowcharts in specific fields (such as academic, technical blogs, or project management).Although these features are not inherently built into the Anqie CMS rendering engine, the system supports integration with third-party libraries through an open architecture and flexible template mechanism, thereby perfectly displaying these advanced content.

Support for mathematical formulas and flowcharts in Anqi CMS Markdown editor

The AnQi CMS Markdown editor enhances the flexibility of content creation, allowing users to write content in a concise Markdown syntax, while also utilizing its extensibility to display complex mathematical expressions and intuitive flowcharts.This ability is achieved by skillfully integrating external JavaScript libraries, which parse specific tags in the Markdown content at page load and render them as high-quality visual elements.

Step 1: Enable Markdown editor

To make use of the advanced features of the Markdown editor, you first need to perform a simple configuration in the Anqi CMS backend.This ensures that when you create or edit a document, you can use Markdown syntax to organize and format content.

You need to access the "Global SettingsIn this page, find and enable the "Markdown Editor" feature.After completing this setting, all new or edited documents will default to using the Markdown editor, laying the foundation for you to insert mathematical formulas and flowcharts later.

Display mathematical formula

In many technical and academic documents, mathematical formulas are indispensable expressions.AnQi CMS integrates the powerful MathJax mathematical display engine to ensure that your formulas are presented on the web page in high quality and easy-to-read manner.MathJax supports LaTeX, MathML, and AsciiMath among various markup languages. Typically, users will use LaTeX syntax to write formulas in Markdown content.

In order for the web page to correctly parse and display these mathematical formulas, you need to include the MathJax CDN resource in the website template. This is usually done in the public header template of the website (for examplebase.html）Complete within. You just need to<head>Add the following JavaScript reference at the end of the tag:

<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>

This code will asynchronously load the MathJax core script. Once loaded, MathJax will automatically scan the page content to find specific tags containing mathematical formulas (for example, inline formulas are usually marked with$...$wrap, used independently in formula$$...$$or\[...\]Wrap it and render it in SVG, MathML, or HTML-CSS format, ensuring clear display on various browsers and devices.

Display flowchart

Flowcharts are an effective tool for visualizing complex processes and logical relationships.Aiqi CMS integrates with Mermaid.js, allowing you to create and render flowcharts directly in Markdown content.Mermaid.js is a JavaScript-based chart drawing tool that uses a concise text syntax to describe various charts, including flowcharts, sequence diagrams, and Gantt charts, etc.

Similar to mathematical formulas, to enable the display of flowcharts, you also need to add the public header template of the website (for examplebase.htmlIn the CDN resource of Mermaid.js is introduced in.<head>Add the following JavaScript code at the end of the tag:

<script type="module">
    import mermaid from 'https://cdn.jsdelivr.net/npm/mermaid@10/dist/mermaid.esm.min.mjs';
    mermaid.initialize({ startOnLoad: true });
</script>

This code imports the Mermaid library via ES module and invokesmermaid.initialize({ startOnLoad: true })The method indicates that Mermaid automatically searches and renders the chart code blocks in the Markdown content after the page is loaded. In the Markdown editor, you usually specify in a code block.mermaidLanguage type to write a flowchart or other Mermaid-supported chart syntax, for example:

```mermaid
graph TD;
    A-->B;
    A-->C;
    B-->D;
    C-->D;

`

By following these steps, when you insert mathematical formulas or flowcharts with MathJax and Mermaid syntax into the Markdown editor, the Anqi CMS page will be rendered in real-time by these third-party libraries after loading on the front end, ultimately presenting professional and interactive visual content to your readers.This greatly enriches the content presentation of Anqi CMS, meeting the diverse content creation needs of users.

Frequently Asked Questions (FAQ)

Question: Can I use other mathematical formula or rendering libraries for flowcharts?

Answer: The template system of Anqi CMS is highly flexible.Although the document recommends MathJax and Mermaid, theoretically, as long as you are familiar with the integration methods of JavaScript libraries and can ensure their compatibility with existing templates and content, you can replace them with other similar rendering libraries.base.htmlEnsure that the template files contain the libraries and that these libraries can correctly parse the formula or chart syntax used in the Markdown editor.

Ask: My mathematical formula or flowchart is still not displaying correctly after configuring according to the steps, how should I troubleshoot?

Answer: If you encounter rendering issues, you can check the following aspects: First, check if the Markdown editor is enabled correctly in the 'Content Settings' of the Anqi CMS backend. Second, confirmbase.htmlIs the CDN link in the file complete and correct, and not blocked by other scripts?You can use the browser's developer tools (F12) to check the console for error messages, or verify that the network request has successfully loaded the MathJax and Mermaid resources. Please confirm that the mathematical formula and flowchart syntax you are using in the Markdown editor is consistent with MathJax (usually LaTeX syntax) and Mermaid requirements.Any minor grammatical error can cause rendering to fail.

Ask: What impact will enabling the rendering function for mathematical formulas and flowcharts on the website have on website performance?

Answer: Introducing JavaScript libraries like MathJax and Mermaid indeed increases the page loading time and client rendering burden, thereby affecting the website performance.Because they need to download and execute scripts on the client side to parse and render content.However, since these libraries are usually loaded through CDNs, browser caching and parallel downloads can be used to optimize speed. If you are very concerned about performance, consider the following optimization measures: Load the corresponding JS library only on pages that contain this special content; use lazy loading techniques, render content only when it enters the viewport; or, if the content is static and does not change frequently, consider pre-rendering these formulas and charts into images or SVG on the server side to reduce client-side computation.
