TypeScript definitions for katex
@types/katex provides TypeScript type definitions for the KaTeX library, which is used for rendering mathematical expressions in web applications.
Render Mathematical Expressions
This feature allows you to render mathematical expressions to HTML using KaTeX. The `renderToString` method converts a LaTeX string into an HTML string.
import katex from 'katex';
const mathExpression = 'c = \pm\sqrt{a^2 + b^2}';
const html = katex.renderToString(mathExpression, {
throwOnError: false
});
console.log(html);
Error Handling
This feature demonstrates how to handle errors when rendering mathematical expressions. By setting `throwOnError` to true, KaTeX will throw an error if the LaTeX string is invalid.
import katex from 'katex';
try {
const html = katex.renderToString('c = \pm\sqrt{a^2 + b^2}', {
throwOnError: true
});
console.log(html);
} catch (error) {
console.error('Error rendering math expression:', error);
}
Custom Rendering Options
This feature shows how to use custom rendering options. The `displayMode` option renders the expression in display mode, and the `output` option specifies the output format (HTML in this case).
import katex from 'katex';
const mathExpression = 'E = mc^2';
const html = katex.renderToString(mathExpression, {
displayMode: true,
output: 'html'
});
console.log(html);
MathJax is another popular library for rendering mathematical expressions in web applications. Unlike KaTeX, MathJax supports a wider range of LaTeX commands and can render both MathML and AsciiMath. However, MathJax is generally slower than KaTeX.
AsciiMath is a simpler alternative to KaTeX and MathJax, designed for rendering mathematical expressions written in AsciiMath notation. It is easier to use but less powerful and flexible compared to KaTeX.
MathLive is a library for creating interactive math editors. It supports rendering LaTeX expressions and provides a rich set of features for editing and interacting with mathematical content. MathLive is more focused on interactivity compared to KaTeX.
