Teste Tecnico: Desenvolvimento de uma Aplicação de Chat em Tempo Real com PHP e Laravel (ou qualquer outra lang)

Introdução

Neste desafio, você será responsável por desenvolver uma aplicação de chat em tempo real utilizando PHP e o framework Laravel. A aplicação deve oferecer funcionalidades básicas similares às encontradas em plataformas de chat como o Discord. O foco principal é a criação de um backend robusto e escalável, utilizando as abstrações e boas práticas do Laravel.

JWT Auth + Refresh Tokens in Rails

This is just some code I recently used in my development application in order to add token-based authentication for my api-only rails app. The api-client was to be consumed by a mobile application, so I needed an authentication solution that would keep the user logged in indefinetly and the only way to do this was either using refresh tokens or sliding sessions.

I also needed a way to both blacklist and whitelist tokens based on a unique identifier (jti)

Before trying it out DIY, I considered using:

The default Postgresql installation on Mac OS X using homebrew includes a single extension - plpgsql (PL/pgSQL procedural language) but there are a number of them available in the lib directory (/usr/local/Cellar/postgresql/9.2.1/lib on my machine)

To install an extension into the database, the easiest way I found was to open a database console using the 'rails db' command and then create it directly. I have seen mention of doing this in a Rails migration but this did not work for me.

Note that an extension is installed in a specific database, rather than being added to all databases.

The command to list the installed extensions is '\dx'

$ rails db
psql (9.2.1)
