I came across HikariCP and I was amazed by the benchmarks and I wanted to try it instead of my default choice C3P0 and to my surprise I struggled to get the configurations right probably because the configurations differ based on what combination of tech stack you are using.

I have setup Spring Boot project with JPA, Web, Security starters (Using [Spring Initializer][1]) to use PostgreSQL as a database with HikariCP as connection pooling.
I have used Gradle as build tool and I would like to share what worked for me for the following assumptions:

1. Spring Boot Starter JPA (Web & Security - optional)
2. Gradle build tool
3. PostgreSQL running and setup with a database (i.e. schema, user, db)

This gist is related to SO post https://stackoverflow.com/questions/26490967/how-do-i-configure-hikaricp-in-my-spring-boot-app-in-my-application-properties-f

Content-Security-Policy, X-Content-Security-Policy, X-WebKit-CSP

O cabeçalho de resposta HTTP Content-Security-Policy permite aos administradores de sites controlar os recursos que o navegador ou agente de usuário (user agent) pode carregar em uma determinada página. Com algumas exceções, as políticas envolvem principalmente especificar as origens do servidor e os endpoints de script. Isso ajuda a proteger contra ataques de XSS.

O cabeçalho de respsota HTTP X-Content-Security-Policy é requerido para implementar o CSP no Internet Explorer 10 e 11.

O cabeçalho de resposta HTTTP X-Webkit-CSP é requerido para implementar o CSP em versões mais antigas do Google Chrome, Safari e outros navegadores baseados na engine WebKit.

Para navegadores modernos, o cabeçalho Content-Security-Policy deve ser usado.

'Include' in Sequelize: The One Confusing Query That You Should Memorize

When querying your database in Sequelize, you'll often want data associated with a particular model which isn't in the model's table directly. This data is usually typically associated through join tables (e.g. a 'hasMany' or 'belongsToMany' association), or a foreign key (e.g. a 'hasOne' or 'belongsTo' association).

When you query, you'll receive just the rows you've looked for. With eager loading, you'll also get any associated data. For some reason, I can never remember the proper way to do eager loading when writing my Sequelize queries. I've seen others struggle with the same thing.

Eager loading is confusing because the 'include' that is uses has unfamiliar fields is set in an array rather than just an object.

So let's go through the one query that's worth memorizing to handle your eager loading.
