isomor-babel

library2.0.2jsnpmunverified

Babel integration for isomor, a framework that abstracts frontend-backend communication by allowing direct function calls from UI code. v2.0.2 (stable, maintained), ships TypeScript types, requires Node >=11. Unlike REST or GraphQL, isomor uses Babel transpilation to automatically separate client and server code within a single project directory. This package provides the Babel plugin that transforms imports and generates the necessary layers. Key differentiator: eliminates API boilerplate by keeping frontend and backend code together, with TypeScript support.
