A webpack loader for parsing json5 files into JavaScript objects.

Getting Started

To begin, you'll need to install json5-loader:

$ npm install json5-loader --save-dev

You can use the loader either:

• by configuring the json5-loader in the module.rules object of the webpack configuration, or
• by directly using the json5-loader! prefix to the require statement.

Suppose we have the following json5 file:

file.json5

{
  env: 'production',
  passwordStrength: 'strong',
}

webpack.config.js

module.exports = {
  module: {
    rules: [
      {
        test: /\.json5$/i,
        loader: 'json5-loader',
        type: 'javascript/auto',
      },
    ],
  },
};

Options

esModule

Type: Boolean Default: true

There are some cases in which using ES modules is beneficial, like in the case of module concatenation and tree shaking.

You can enable a ES module syntax using:

webpack.config.js

module.exports = {
  module: {
    rules: [
      {
        test: /\.json5$/i,
        loader: 'json5-loader',
        options: {
          esModule: false,
        },
        type: 'javascript/auto',
      },
    ],
  },
};

Examples

Usage with require statement loader prefix

file.json5

{
  env: 'production',
  passwordStrength: 'strong',
}

index.js

import appConfig from 'json5-loader!./file.json5';

console.log(appConfig.env); // 'production'

Don't forget to polyfill require if you want to use it in Node.js. See the webpack documentation.
