Unlocking the Power of Large Numbers in Angular with Webpack

Error: [$injector:unpr] Unknown provider: BigNumberProvider

Recently, I embarked on a new project using Webpack + Angular.JS and encountered an issue while trying to incorporate Bignumber.js.

Here's a snippet of my Webpack configuration:

  resolve: {
      root: [path.join(__dirname, 'assets/libs/bower_components'), 'node_modules']
    },
    entry: {
      entry: ['./app/app.js'],
      vendor: [
          'lodash',
          'bignumber.js',
          'angular'
          ....

Since Bignumber.js is a library, I did not include it as a dependency in my main app.js. However, I am currently facing challenges injecting it into my directive:

app.directive('createpayment', [
      '$http',
      ' * ', // I've tried BigNumber, bignumber, binumber.js but none seem to work
             // Unfortunately, the README does not provide any guidance on this issue
      function($http, BigNumber ? , bignumber ? ) {

Answer №1

To achieve this functionality, you can make use of the ProvidePlugin plugin in webpack:

webpack.config.js

...
plugins: [
  new webpack.ProvidePlugin({
    BigNumber: 'bignumber.js',
    lodash: 'lodash',
    $: 'jquery'
  }),
]
...

In order to use the ProvidePlugin, ensure that you have included a resolve declaration in your webpack configuration.
