+I was writing a small Dart web server today, and got tired of constantly restarting it manually: <kbd>ctrl</kbd>-<kbd>\`</kbd>, <kbd>ctrl</kbd>-<kbd>c</kbd>, <kbd>up arrow</kbd>, <kbd>enter</kbd>. I mean, it's not a huge amount of work, but it adds up - and it's easy to miss a step (or all of them).
+
+After searching and getting into the weeds of [how to do hot reload in Dart](https://www.reddit.com/r/dartlang/comments/66fiop/using_dart_vms_hot_reload_feature_to_build_an/) (which is what Flutter uses), I came across this [Reddit comment](https://www.reddit.com/r/dartlang/comments/mcsgrb/comment/gs5lqkn/) that shows a much simpler solution:
+```
+nodemon -x "dart run bin/server.dart" -e dart
+```
+
+In here:
+
+* `nodemon` is the [application](https://github.com/remy/nodemon) that does the monitoring and executing.  Originally written for node, it works with any executable now.
+* `-x "dart run bin/server.dart"` tells it to execute `dart run bin/server.dart`. Modify that last bit to point to your main Dart file.
+* `-e dart` then tells it to monitor `.dart` files for changes. If it detects a change, it kills the current process and starts a new one.
+
+Simple, but it works - so highly recommended.
