@swc/helpers provides runtime functions that are essential for supporting various JavaScript and TypeScript features when using the SWC compiler. These helpers ensure compatibility across different environments by providing polyfills and utility functions necessary for features like classes, async/await, decorators, and more. By including these helpers, developers can leverage modern language constructs while maintaining broader runtime compatibility without the need for large, general-purpose polyfill libraries. This package minimizes bundle size and improves application performance.
@swc/helpers releases are sporadic. There were no releases between March 2019 and September 2020. Releases peaked in April 2021 and August 2023 with 7 and 12 versions respectively. In 2025, only one release occurred in April. There have been no releases in the last four months (May-August) and so far September 2025.
