A Babel plugin that pre-evaluates JavaScript code at build time, replacing expressions with their computed results. It lets you run Node.js code (like filesystem reads) during compilation and inline the exported value into your bundle.

Use cases

  • inline file contents into a bundle at build time
  • run node code during compilation instead of runtime
  • read the filesystem in browser-targeted code
  • precompute constants at build time
  • evaluate code with babel-plugin-macros

When to avoid

  • your build does not use Babel
  • the evaluated code depends on runtime state
  • you need evaluation in non-JavaScript toolchains like Vite or esbuild without Babel
