Do you want to turn your ManimCE code into an interactive web animation? This is your library!

• MathJax LaTeX rendering: As we're using a web browser, we can't use system's LaTeX. Instead, we use a really faster implementation called MathJax, that delivers math equations for the web. Notice that there's no Tex, so you can do MathTex(f"\\text{{{tex_code}}}") to render LaTeX text instead of Tex(tex_code).
• Text rendering without Pango (under development): As Pango needs a system, we can't render text with Pango, but we'll use JavaScript libraries to handle that stuff (you don't need any JS, just internal working). This is still under development, so if you try to call Text("Hello, world!"), this will raise an error, because Text isn't still ready!
• Interactive animations and integration with JavaScript: You can now create interactive animations that can be controlled by the user. This is done by using JavaScript to handle events and Manim Web to create the animations.

Wait, this is not a system library, so you don't need to install it! In fact, you must start with an HTML file that includes Pyodide and loads Manim Web with micropip.install("manim-web"). An example is at the demo section below.

You have an example at https://mathityt.github.io/manim-web-demo/. The source code is at https://github.com/MathItYT/manim-web-demo.

You can use Manim Web like you use ManimCE, but with some differences. Some objects and methods are not available, like Text mobject.

from manim import *


class MyScene(Scene):
    def construct(self):
        # Create a square
        square = Square()
        # Add the square to the scene
        self.add(square)
        # Wait for 1 second
        self.wait(1)
        # Rotate the square
        self.play(square.animate.rotate(PI / 4))
        # Wait for 1 second
        self.wait(1)

• No Pango text rendering: As mentioned above, Pango is not available in the web, so text rendering is not available yet. But Text will be available soon!

Thanks to the Manim Community developers and 3Blue1Brown for developing a great animation engine!
