ESBuild plugin for JSY syntax transpilation to standard JavaScript. Current version 0.0.2 is experimental with no regular release cadence. JSY is a custom JavaScript superset that compiles to standard JS. This plugin allows using JSY files directly in ESBuild builds. Key differentiators: minimal configuration, integrates JSY transpilation into ESBuild pipeline. Alternatives include using JSY CLI separately.
