pkg.macro ·

Fetch properties of your project's package.json at compile time.

pkg.macro allows you to turn pkg(["name", "version"]) into { name: "your-package", version: "1.0.0" } as a build time constant.

installation

yarn add --dev pkg.macro

Make sure you also have [Babel][babel] and [babel-plugin-macros][babel-plugin-macros] installed:

yarn add --dev @babel/cli @babel/core babel-plugin-macros

... and configured with Babel:

module.exports = {
  presets: [],
  plugins: ["babel-plugin-macros"]
}

usage

import pkg from "pkg.macro"
 
const props = pkg([
  "name",
  "version",
  "scripts.test",
  ["dependencies", "some-package"]
])

The above is transformed to:

const props = {
  name: "your-package",
  version: "1.0.0",
  scripts: {
    test: "test-script"
  },
  dependencies: {
    "some-package": "1.0.0"
  }
}
