-## Advanced Configuration
-
-### esbuild
-
-As an escape hatch, you may optionally specify a function which will receive the final esbuild options generated by this adapter and returns a modified esbuild configuration. The result of this function will be passed as-is to esbuild. The function can be async.
-
-For example, you may wish to add a plugin:
-
-```js
-adapterCfw({
-	esbuild(options) {
-		return {
-			...options,
-			plugins: []
-		};
-	}
-});
-```
-
-The default options for this version are as follows:
-
-```js
-const options = {
