Dropwizard and Angular Apps Example

A simple example of creating Dropwizard Application as Backend and Angular as Frontend. This project is tested with dropwizard 2.x, Java 8, and Angular 12.

Features

• REST Endpoint
• Authentication and Role Based Authorization with JWT. In this example we use identityserver4 demo server. It can be change to any oauth2/jwt server.
• Swagger page to test the API
• Unit Test
• Validation of POJO request with annotation
• Custom Appender for logging
• Accesing HttpServletRequest variable
• Dockerized
• Angular 12 AdminLTE Front End (slightly modified from https://github.com/erdkse/adminlte-3-angular)

Build

• Install nodejs
• Run this to install required NPM and build angular AdminLTE:

cd src/adminlte-3-angular
npm install
ng build --base-href=/angular/

• Use mvn package to build the module into jar file

mvn clean package

• Create configuration file ( see config example in config.yml in the project repo)
• Run the resulting jar:

java -jar dropwizard-example.jar server <config_file_path>

Docker

• Build the package as above in [Build]
• Go to the root directory of the project and run:

docker build -t dropwizard-sample .

• And then run the docker image:

docker run -p 8080:8080 dropwizard-sample

• Go to the browser and try to open swagger in http://localhost:8080/swagger
• Go to the browser and try to open the AdminLTE Angular app in http://localhost:8080/angular/

Configuration

• Please check the config.yml example in the repo
• The configuration example is based on use-case of application authenticating using identityserver4 demo url.

Feedback

For feedback, please raise issues in the issue section of the repository. Periodically, I will update the example with more real-life use case example. Enjoy!!.
