import-module-string

import-module-string

Use import('data:') to execute arbitrary JavaScript strings. A simpler alternative to node-retrieve-globals that works in more runtimes.

Features

• Multi-runtime: tested with Node (18+), Deno (limited), Chromium, Firefox, and WebKit.
• Defers to export when used, otherwise implicitly export all globals (via var, let, const, function, Array or Object destructuring assignment, import specifiers, etc)
• Emulates import.meta.url when filePath option is supplied
• addRequire option adds support for require() (in Node)
• Extremely limited dependency footprint (acorn for JS parsing only)
• Allows providing an external data object to pass in data (must be JSON.stringify friendly)

Limitations

• import (in Browser) targets must be mapped via an Import Map in HTML.
• import (in Node) targets are limited to built-in modules only.
• Context data passed to script must be JSON.stringify-friendly (more serialization options may be added later).
• Script content size maximums: Chrome 512MB, Safari 2048MB, Firefox 512MB, Firefox prior to v137 32MB
