Installation

This page covers three things: the install command, the two external assets, and browser requirements. For what the package is and where it fits, see Overview.

pnpm add manim-live

The package is pure ESM (exports contains only import) and needs a bundler that resolves node_modules — vite, webpack, and rspack all work. manim-web is installed with the package (it sits in dependencies) but is not bundled into this package's output: it is left for the consumer's bundler to resolve, which helps tree-shaking and caching.

The package contains logic only

The files allowlist is dist, style.css, README.md, LICENSE. The static assets required at runtime are not distributed with the package — see the two sections below.

External assets

Pyodide

About 13 MB for the core, plus about 7 MB for the bundled numpy and sympy. Pointed to by pyodideIndexURL of createManimRenderer; if omitted, the official CDN is used. For offline or self-hosted setups, pass your own address and note two things:

• The Pyodide core and the on-demand third-party packages (pandas, matplotlib, and friends) read the same address, and are SRI-verified against the sha256 in pyodide-lock.json — whichever file is missing from that address, the corresponding import simply cannot be fetched. The complete self-hosting recipe is in Third-Party Packages.
• Pyodide is licensed under MPL-2.0: when served from the CDN this package is not the distributor; when self-hosted you must include its LICENSE and note where the source lives.

KaTeX

MathTex renders to KaTeX HTML and needs the styles to display correctly; the CSS and fonts are pointed to by katexBaseURL. If omitted, the DOM is left untouched — if your code uses no formula text, you can skip this entirely.

Browser requirements

A modern browser with WebAssembly and WebGL support: Pyodide runs WASM and manim-web renders with three.js. DOM-less environments (Node) use the manim-live/node entry, which supports the dry-run precheck only; see Node Precheck.

For the readiness of the four condition groups — capabilities, runtime, KaTeX, package fetching — and its subscribable changes, see Environment Status.
