has-package-exports

Does the current node version have support for the "exports" field in package.json?

At the time of this writing, node v12.17+ and v13+ has support for the "exports" field in package.json.

This library exports true if the current node version supports it, false if it does not, and null if it's in a browser.

Require or import has-package-exports/conditional to determine if the current environment supports conditional exports (as of this writing, node v12.17+ and v13.7+).

Require or import has-package-exports/pattern to determine if the current environment supports exports patterns (as of this writing, node v12.20+ and v14.13+).

Require or import has-package-exports/pattern-trailers to determine if the current environment supports exports pattern trailers (as of this writing, node v14.19+ and v16.9+).

Tests

Simply clone the repo, npm install, and run npm test
