esbuild-plugin-userscript

ESbuild plugin suite for building userscripts targeting Tampermonkey, Greasymonkey, Violentmonkey, and other userscript engines. Current stable version is 0.2.6. The package provides three distinct plugins: `userscript-inject-code` for injecting code fragments, `userscript-metadata` for generating metadata headers (e.g., @name, @match, @grant), and `userscript-proxy` to create development proxy scripts that bypass browser cache during development. Unlike general bundler plugins, this package is purpose-built for userscript workflows, supporting both CommonJS and ESM via esbuild. Key differentiators include combined or individual plugin usage, TypeScript-first design, and minimal configuration overhead.
