Generating eventsearch backbone with jhipster generator tutorial


Let’s start to create backbone of our application in jhipster. In this part we will focus on setup environment and have a fun with jhipster console generator.

Setup part

At the beginning we need to configure some libraries. I hope you have your java JDK, basic groovy and node js installed.

npm install -g yo

Installation of yeoman – scaffolding tool which help us generate whole structure.

npm install -g bower

Installation of bower – package manager, which will download all libs, such as jquery.

npm install -g grunt-cli

Javascript task runner, you can use it for exampe for minification css.

npm install -g generator-jhipster

And jHipster generator is on your desk.

 

Prepare database for application

We need to install Postgres database with pgAdmin. After installation we want to create new user, new database and grant user access to the database.

create database evsdb;
CREATE DATABASE
Query returned successfully in 3 secs.

create user evsuser with password 'pwdevs';
CREATE ROLE
Query returned successfully in 499 msec.

grant all privileges on database evsdb to evsuser;
GRANT
Query returned successfully in 708 msec.

 

Run jHipster generator

You will have 15 questions how should look like your application. You need to choose type of application (eg. standard monolithic), app name, namespace name, type of authentication, caching, type of angular (I’ve choosed 1.x angular because I’ve been using it a long time ago and for this app will be enought) and lot’s more. Please take a look at console sceenshot from jhipster generator below (please open it as image in new tab).

I’ve also installed some additional modules to check what it is. Probably they are useless for now, but maybe some day I will use them or clean it up 😉

 

? (1/15) Which *type* of application would you like to create? Monolithic application (recommended for simple projects)
? (2/15) What is the base name of your application? eventsearch
? (3/15) Would you like to install other generators from the JHipster Marketplace? Yes
? Which other modules would you like to use? (generator-jhipster-bootstrap-material-design-3.5.1) Add Material design to your JHipster application [Thibaut Mottet], (generator-jhipster-spring-social-connectors-0.0.1) Add Spring social connector to your JHips
ter application [Thibaut Mottet], (generator-jhipster-elasticsearch-reindexer-0.3.0) Generate a service for reindexing all database rows for each of your entities [Gerald Humphries], (generator-jhipster-material-0.0.0) A Jhipster based generator to create An
gular material + spring boot application [Deepu KS], (generator-jhipster-fortune-0.0.2) Sample JHipster module, generates a "fortune cookie" page in your JHipster application [Julien Dubois], (generator-jhipster-google-analytics-0.0.1) Install Google analyti
cs on your JHipster app [Thibaut Mottet], (generator-jhipster-google-maps-0.0.1) Install Google maps sample on your JHipster app [Thibaut Mottet]
? (4/15) What is your default Java package name? com.pdb.eventsearch
? (5/15) Which *type* of authentication would you like to use? JWT authentication (stateless, with a token)
? (6/15) Which *type* of database would you like to use? SQL (H2, MySQL, MariaDB, PostgreSQL, Oracle, MSSQL)
? (7/15) Which *production* database would you like to use? PostgreSQL
? (8/15) Which *development* database would you like to use? PostgreSQL
? (9/15) Do you want to use Hibernate 2nd level cache? Yes, with ehcache (local cache, for a single node)
? (10/15) Would you like to use Maven or Gradle for building the backend? Gradle
? (11/15) Which other technologies would you like to use? Social login (Google, Facebook, Twitter), Search engine using Elasticsearch, WebSockets using Spring Websocket
? (12/15) Which *Framework* would you like to use for the client? AngularJS 1.x
? (13/15) Would you like to use the LibSass stylesheet preprocessor for your CSS? No
? (14/15) Would you like to enable internationalization support? Yes
? Please choose the native language of the application? English
? Please choose additional languages to install Polish
? (15/15) Besides JUnit and Karma, which testing frameworks would you like to use?
(*) Gatling
(*) Cucumber
>(*) Protractor

Now we need to prepare all files in frontend to works fine using:

npm install && bower install

And change database credential in application-dev.yml file:

datasource:
    type: com.zaxxer.hikari.HikariDataSource
    url: jdbc:postgresql://paweldobrzanski.pl:5432/evsdb
    username: evsuser
    password: pwdevs

And it’s working!!!

Rigth now we have simple application with

  • ability to login and register,
  • internationalization is being enabled
  • looks cool with bootstrap – material design…oh what?
  • has a lot of stuff in admin mode 🙂

One more thing: material design. We need to generete it!

yo jhipster-bootstrap-material-design

 

In next tutorial we will be generating application model, see you next week!
