More talk on Clojure! Diego will give us more details to using Clojure. It should prove interesting!

Note, this meeting will be on a Wednesday and in Natomas.

Brian

Social Meetup at Kupros. See you there. It appears that many of us have been using Thinkpads running GNU/Linux. Bring which gadget you have and hang out and socialize.

We will be at Bel Air Market at Arden. Please see the locations link to see the location.

Have you ever wanted to learn Lisp?

Clojure is a modern Lisp running on the Java Virtual Machine to build Web servers.

In this talk, we’ll learn a little bit about Lisp and its history and variants, understand how to operate Lisp systems, install Clojure, start a Compojure project, and build a simple Lisp-based web server in Compojure that will output a factorial function.

We will be at Kupros for this meeting. This will be a social hangout. Bring whatever gadget or your favorite project or questions (maybe we can answer), and socialize.

We will explore integrating a React application into Liferay per David Nebingers blog post, From React App to React Client Extension in 5 Easy Steps.

We will be at the Bel Aire Something Extra Gather Room again on Arden.

More hands on demo with Spring Boot and React.

Full Stack Development with React

We will continue to walk through various aspects of the Full Stack Development with Spring Boot 3 and React: Build modern web applications using the power of Java, React, and TypeScript, Fourth Edition using Fedora 40.

Last session, we implemented various CRUD operations. We will continue the process. We will continue with CRUD (Create, Read, Update, Delete) operations, yet perhaps add the security components to the REST layer and other aspects!

Examples

The 4th editon uses Gradle, React/Vue, and Typescript!

We will be at the Bel Aire Something Extra Gather Room again on Arden.

The room has a large screen TV with HDMI in, so we will have some sort of hands on demo.

Full Stack Development with React

Just when you thought you had everything going with the older way of doing things, there is the 4th Edition!

We will be back at Bel Aire in their meeting room.

Full Stack Development with React

We will walk through various aspects of the Full Stack Development with Spring Boot and React using Fedora 40.

Examples

Tools in use

1. Fedora 40
2. Eclipse
3. VS Code
4. MariaDB sudo dnf install mariadb-server
5. Postman
6. nvm
7. Mysql JDBC driver
8. Fedora Java Alternatives

Create the database and the user

create database cardb character set utf8;

GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER,
CREATE TEMPORARY TABLES ON cardb.*
TO 'brian'@'localhost' IDENTIFIED BY 'Rockit2';

Spring resource to connect to mysql

spring.datasource.url=jdbc:mariadb://localhost:3306/cardb 
spring.datasource.username=brian
spring.datasource.password=Rockit2
spring.datasource.driver-class-name=org.mariadb.jdbc.Driver
spring.jpa.generate-ddl=true 
spring.jpa.hibernate.ddl-auto=create-drop

spring.jpa.show-sql=true
spring.jackson.serialization.FAIL_ON_EMPTY_BEANS=false
spring.data.rest.basePath=/api

Fix eclipse crashing. Add this to .bashrc

export WEBKIT_DISABLE_COMPOSITING_MODE=1

Verify nvm configuration for the shell.

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Start database

sudo service mariadb start

Check that user can connect to MariaDB

mysql -u brian -p cardb

Import Chapter 5 example code and modify SecurityConfig.java per book [Hinkula,238]. We will not have security settings for this demonstration.

http.csrf().disable().cors().and()
    .authorizeRequests().anyRequest().permitAll();

Update application.properties

Start CarDatabaseApplication.java.

Verify REST interface for cars with PostMan

Check npm conifuguration. Create carfront skeleton and install library dependencies [Hinkula,239].

npx create-react-app carfront
cd carfront
npm install @mui/material @emotion/react @emotion/styled

Add the components folder to carfront project [Hinkula,245]. Create Carlist.js and add content.

Verify that the Spring Boot backend is running CardatabaseApplication. Start the React application from the terminal npm start.
