framejs.io

Create, modify, and share interactive browser apps and visualizations from JavaScript via framejs.io. The app is encoded into a shareable URL that runs instantly — no build, server, or account. Use when the user wants a chart, graph, plot, dashboard, animation, simulation, creative coding sketch, data visualization, or small interactive web tool; when they reference a framejs.io short URL (/j/<sha256>) to modify; or when they want to visualize a local data file (CSV, JSON, image, etc.).

How this repo's visual style (the editor AND the docs) is derived from framejs.app's design system, and the exact steps to re-merge it when framejs.app changes. Load whenever restyling the editor or docs, updating palette/fonts/tokens, syncing the "blueprint" look from the framejs-nhost sibling repo, or editing editor/src/styles/blueprint.css, theme.ts, or docs/.vitepress/theme/blueprint.css.

Maps the framejs.io / framejs.app origin split between this repo and its sibling framejs-nhost repo, plus each one's local dev address. Load whenever working with cross-app URLs, FRAMEJS_APP_ORIGIN/FRAMEJS_IO_ORIGIN env vars, or debugging requests between the rendering runtime and the account layer.
