babel-plugin-pkg

Resolves _PKG_VERSION to version from package.json - also works with any other field!

This plugin attempts to dynamically replace expressions starting with process.env.REPLACE_PKG_.

Installation

npm install --save-dev babel-plugin-pkg@^2.1.0

yarn add --dev babel-plugin-pkg@^2.1.0

npm install --save-dev @jaid/babel-plugin-pkg@^2.1.0

Reference fields from your package.json in your source files.

package.json

{
  "name": "readable-ms",
  "version": "1.2.3"
}

src/index.js

console.log(`This is ${process.env.REPLACE_PKG_NAME} v${process.env.REPLACE_PKG_VERSION}`)

This will be transpiled to: dist/index.js

console.log("This is readable-ms v1.2.3")

Add to your Babel configuration.

.babelrc.js

module.exports = {
  plugins: [
    "pkg"
  ]
}
