mathjax editor for react

Note: The full documentation is available at https://github.com/Orcish-Y/react-mathjax-editor

  This library provides a user-friendly React component for visualizing mathematical formulas. Users can build the desired mathematical formulas by clicking and interacting with an intuitive input panel, and these formulas will be displayed in real-time on the interface. Additionally, by adjusting schema (configuration) parameters, you can customize the formula symbols in the input panel, making this component better suited to your project. Whether it's mathematical, chemical, or other scientific symbols, this component can provide you with a flexible and convenient formula input experience. Installing and using this component is very simple, without complex configuration or knowledge of mathjax. Simply follow the provided guidelines, and you can easily integrate this powerful mathematical formula input component into your React project.

pnpm add react-mathjax-editor

🔨 Usage

Mathjax Editor

import React, { useState } from 'react';
import { MathJaxEditor } from 'react-mathjax-editor';

export default () => {
  const [value, setValue] = useState<string>();
  return <MathJaxEditor value={value} onChange={setValue} />;
};

Use with forms

import { Button, Form } from 'antd';
import React from 'react';
import { MathJaxEditor } from 'react-mathjax-editor';

export default  () => {
  return (
    <Form onFinish={(value) => console.log('do something')}>
      <Form.Item label="MachJax" name="machJax" rules={[{ required: true }]}>
        <MathJaxEditor  />
      </Form.Item>
      <Form.Item>
        <Button type="primary" htmlType="submit">
          Submit
        </Button>
      </Form.Item>
    </Form>
  )

Mathjax Panel

import React, { useState } from 'react';
import { MathJax, MathJaxContext, MathJaxPanel } from 'react-mathjax-editor';

export default () => {
  const [value, setValue] = useState<string>();
  return <MathJaxPanel value={value} onChange={setValue} />;
};

Rendering formula

import React from 'react';
import { MathJax, MathJaxContext } from 'react-mathjax-editor';

export default () => {
  const methJaxString = `\\left( \\sum_{k=1}^n a_k b_k \\right)^{\\!\\!2}\\leq
\\left( \\sum_{k=1}^n a_k^2 \\right) \\left( \\sum_{k=1}^n b_k^2 \\right) `;

  return (
    <MathJaxContext>
      <MathJax inline dynamic>
        {`$$ ${methJaxString} $$`}
      </MathJax>
    </MathJaxContext>
  )
