+# 3. Reduce main file size on Web Browser
+
+Date: 2022-04-04
+
+## Status
+
+Accepted
+
+## Context
+
+- Reduce `main.dart.js` file size at web browser startup
+
+## Decision
+
+- We use [Lazily loading](https://dart.dev/guides/language/language-tour#lazily-loading-a-library) which could split your code in multiple JavaScript files
+
+## Consequences
+
+- Significantly reduce the size of the generated `main.dart.js` file.
