The Observable standard library (@observablehq/stdlib), a JavaScript library providing utilities for Observable notebooks including DOM element creation, file reading, generators, promises, and rendering of HTML, Markdown, SVG, and LaTeX. It is the runtime support library underlying Observable notebooks and can be used standalone.

Use cases

• render html and markdown from tagged template literals in javascript
• read local and remote files in a notebook environment
• load third-party libraries dynamically with require
• create canvas and svg elements with proper pixel density
• handle promise and generator utilities for reactive notebooks
• dispose resources when a notebook cell is invalidated

When to choose

• you are building or extending Observable notebooks or Framework projects
• you need lightweight DOM, file, and rendering helpers in a browser-based notebook
• you want reactive cell utilities like invalidation and visibility

When to avoid

• you need a full frontend framework or UI component library
• you are building a server-side application without browser DOM
• you want a general-purpose utility belt like lodash
