+### webpack
+
+If you're using webpack with `target: node` (e.g. for testing), you can avoid warnings about the dynamic `require` by adding the following to your configuration ([more info](andris9/encoding#16)):
+
+```js
+{
+  module: {
+    exprContextRegExp: /$^/,
+    exprContextCritical: false
+  }
+}
+```
