This project use to learn how to create simple webapp with Vert.x 3.0.
You can run it directly in your IDE by creating a run configuration that uses the main class io.vertx.core.Starter
and passes in the arguments run app.web.Server.
The build.gradle uses the Gradle shadowJar plugin to assemble the application and all it's dependencies into a single "fat" jar.
To build the "fat jar"
1. Make sure you have MySQLServer and execute database scripts (see : src/main/resources/sql/scripts.sql)
2. Verify app config and change if needed (see : src/main/resources/config.json)
3. ./gradlew shadowJar
To run the fat jar:
java -jar build/libs/vertx-web-1.0.0-SNAPSHOT-fat.jar
(You can take that jar and run it anywhere there is a Java 8+ JDK. It contains all the dependencies it needs so you don't need to install Vert.x on the target machine).
Now point your browser at http://localhost:8080
Writing code in verticles allow you to scale it more easily, e.g. let's say you have 8 cores on your server and you want to utilise them all, you can deploy 8 instances as follows:
java -jar build/libs/vertx-web-1.0.0-SNAPSHOT-fat.jar -instances 8
You can also enable clustering and ha at the command line, e.g.
java -jar build/libs/vertx-web-1.0.0-SNAPSHOT-fat.jar -cluster
java -jar build/libs/vertx-web-1.0.0-SNAPSHOT-fat.jar -ha
Please see the docs for a full list of Vert.x command line options.
#Things I want todo
- CRUD
- Validation, right now there's no input validation
- Upload File sample
- Websocket sample, eg: provide chatting box for logged in user
