JSON Strip Loader

JSON loader for Webpack, with support for keys stripping, useful in isomorphic builds for storing secrets in JSON files.

The main use case for this loader comes when using a JSON settings file containing some secret keys, that you want to use on the server but don't want to make public on the client.

Let's say your settings.json looks like this:

{
  environment: 'production',
  secret: 'password',
  AWS: {
    secret: 'password'
  }
}

Now you can use json-strip-loader as a drop-in replacement for json-loader on your server webpack configuration:

  use: 'json-strip-loader'

And you can strip out the secrets on your client webpack configuration:

  use: 'json-strip-loader?key=secret'

Install

$ npm install --save json-strip-loader

Webpack Configuration

module.exports = {
  module: {
    rules: [{
      test: /\.json$/,
      use: 'json-strip-loader', // Simply load the file
      use: 'json-strip-loader?key=secret', // Remove the keys names `secret` from the files
      use: 'json-strip-loader?key=secret&deep=false', // Remove `secret` only from the root level
      use: 'json-strip-loader?keys[]=secret,keys[]=server' // Remove the keys names `secret` and `server` from the files
    }]
  }
}

CLI

webpack --module-bind 'json=json-strip-loader'

Inline

import file from 'json-strip-loader!file.json';
