## Webpack Configs
|
||||
|
||||
With WebPack 5, you have to be explicit about the usage of Node.js types and
|
||||
modules that were simply replaced with re-implementations for browsers in
|
||||
Webpack 4.
|
||||
|
||||
Configs for 0.28 and later:
|
||||
|
||||
```js
|
||||
module.exports = [
|
||||
{
|
||||
...,
|
||||
resolve: {
|
||||
fallback: {
|
||||
buffer: false,
|
||||
crypto: false,
|
||||
events: false,
|
||||
path: false,
|
||||
stream: false,
|
||||
string_decoder: false,
|
||||
},
|
||||
},
|
||||
},
|
||||
];
|
||||
```

||||

module.exports = [

resolve: {
|
||||
fallback: {
|
||||
buffer: false,
|
||||
crypto: false,
|
||||
events: false,
|
||||
path: false,
|
||||
stream: require.resolve("stream-browserify"),
|
||||
string_decoder: false,
|
||||
},
|
||||
},
|
||||
},
|
||||
];
|
||||
```
|
||||
|
||||
Also, in both cases you need the Buffer plugin:
|
||||
|
||||
```ts
|
||||
module.exports = [
|
||||
{
|
||||
...,
|
||||
plugins: [
|
||||
...,
|
||||
new webpack.ProvidePlugin({
|
||||
Buffer: ["buffer", "Buffer"],
|
||||
}),
|
||||
],
|
||||
...
|
||||
},
|
||||
];
|
