Force webpack to use a lib e.g: buffer

[abdallahkadour]

How I can do that in config.webpack.js:
When I try

webpack.chainWebpack((config) => {
    config.plugins = [
      new webpack.ProvidePlugin({
        Buffer: ['buffer', 'Buffer']
      })
    ]

I got an error saying ProvidePlugin is not a constructor

For anyone else reading: make sure that you install the buffer node module, for one thing.

npm install --save buffer

I'm not actually sure whether both of these blocks are needed, but this worked in my case.

config.resolve.set('fallback', {
    Buffer: require.resolve('buffer'),
});

config
.plugin('BufferPlugin')
.use(require.resolve('webpack/lib/ProvidePlugin'), [
    { Buffer: ['buffer', 'Buffer'] },
]);
