								# @rollup/plugin-json
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								🍣 A Rollup plugin which Converts .json files to ES6 modules.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								## Requirements
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								This plugin requires an [LTS](https://github.com/nodejs/Release) Node version (v8.0.0+) and Rollup v1.20.0+.
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								## Install
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								Using npm:
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								```console
							 | 
						||
| 
								 | 
							
								npm install @rollup/plugin-json --save-dev
							 | 
						||
| 
								 | 
							
								```
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								## Usage
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								Create a `rollup.config.js` [configuration file](https://www.rollupjs.org/guide/en/#configuration-files) and import the plugin:
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								```js
							 | 
						||
| 
								 | 
							
								import json from '@rollup/plugin-json';
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								export default {
							 | 
						||
| 
								 | 
							
								  input: 'src/index.js',
							 | 
						||
| 
								 | 
							
								  output: {
							 | 
						||
| 
								 | 
							
								    dir: 'output',
							 | 
						||
| 
								 | 
							
								    format: 'cjs'
							 | 
						||
| 
								 | 
							
								  },
							 | 
						||
| 
								 | 
							
								  plugins: [json()]
							 | 
						||
| 
								 | 
							
								};
							 | 
						||
| 
								 | 
							
								```
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								Then call `rollup` either via the [CLI](https://www.rollupjs.org/guide/en/#command-line-reference) or the [API](https://www.rollupjs.org/guide/en/#javascript-api).
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								With an accompanying file `src/index.js`, the local `package.json` file would now be importable as seen below:
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 | 
							
								```js
							 | 
						||
| 
								 | 
							
								// src/index.js
							 | 
						||
| 
								 | 
							
								import pkg from './package.json';
							 | 
						||
| 
								 | 
							
								console.log(`running version ${pkg.version}`);
							 | 
						||
| 
								 | 
							
								```
							 | 
						||
| 
								 | 
							
								
							 | 
						||
| 
								 |

							 | 
						||
| 
								 | 
							
								A [minimatch pattern](https://github.com/isaacs/minimatch), or array of patterns, which specifies the files in the build the plugin should _ignore_. By default no files are ignored.

							 | 
						||
|

							 |

| 
								 |
