esbuild-plugin-virtual

An esbuild plugin for loading virtual modules from memory, inspired by @rollup/plugin-virtual. Version 0.1.0 is designed for esbuild's plugin system, enabling in-memory module resolution during bundling. Releases are stable but infrequent. Key differentiators: simple API (object map of module names to content), works with both Node and Deno, virtual modules are resolved with a 'virtual:' prefix internally. Compared to file-based alternatives, it eliminates filesystem I/O for tests or dynamic content. Currently ships TypeScript definitions, but lacks advanced features like virtual directories or lazy loading.
