xyz.jetdrone:hot-reload
Advanced tools
This is a experimental vertx-web handler for hot reload. This handler is used in the webpack-vertx-plugin but it is not necessary to, you can also use it independently.
This module provides 2 handlers in one:
hot-reload script + backend based either in SSE or poolingThe script can listen for updates either as a SSE stream or using pooling. It defaults to SSE as it is supported on modern web browsers but for legacy it can be configured to perform HTTP pooling.
A static handler will be returned using this factory. If there is a
file named .hot-reload on the current working directory then the static
handler is configured to not cache both the filesystem and the http responses.
In your application router you should add the following code:
final Router router = Router.router(vertx);
// development hot reload
router.get().handler(HotReload.create());
...
// Serve the static resources
router.route().handler(StaticHandler.create());
When there isn't a file named .hot-reload in the current working directory the handler will
be a NO-OP handler and the last will return a unmodified StaticHandler.
In your html application you should have:
<!DOCTYPE html>
<html>
<body>
<script src="/hot-reload/script"></script>
</body>
</html>
When you start your application you should have the control file in the current working directory e.g.:
touch .hot-reload
java -jar target/fatjar.jar
Navigate to your HTML page where you loaded the script, and after that update the contents of the reload control file e.g.:
echo "update!" >> .hot-reload
You will notice that a reload is triggered on the browser.
