Package Exports

rollup-plugin-json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (rollup-plugin-json) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

rollup-plugin-json

Convert .json files to ES6 modules:

// import a single property from a JSON file,
// discarding the rest
import { version } from './package.json';
console.log( `running version ${version}` );

// import the whole file as an object
import pkg from './package.json';
console.log( `running version ${pkg.version}` );

Installation

npm install --save-dev rollup-plugin-json

Usage

// rollup.config.js
import json from 'rollup-plugin-json';

export default {
  input: 'src/main.js',
  output: {
    file: 'dist/bundle.js',
    format: 'iife'
  },

  plugins: [
    json({
      // All JSON files will be parsed by default,
      // but you can also specifically include/exclude files
      include: 'node_modules/**',
      exclude: [ 'node_modules/foo/**', 'node_modules/bar/**' ],

      // for tree-shaking, properties will be declared as
      // variables, using either `var` or `const`
      preferConst: true, // Default: false

      // specify indentation for the generated default export —
      // defaults to '\t'
      indent: '  ',

      // ignores indent and generates the smallest code
      compact: true, // Default: false

      // generate a named export for every property of the JSON object
      namedExports: true // Default: true
    })
  ]
};
