rollup-plugin-jscc

Rollup plugin for conditional compilation and compile-time variable replacement using jscc. Current stable version is 2.0.0, released 2020-08-28, with a maintenance cadence (last major release). Key differentiators: runs before transpilers as a file loader (or optionally as transformer), supports TypeScript definitions, sourcemaps, and uses full JavaScript expressions for conditional blocks. Unlike other preprocessors, it is language agnostic and tightly integrated with Rollup v2+, requiring Node >=10.12.0.
