1. What is in the stack?
We use Symfony, a PHP framework using for website app development for front end and back end development.
2. How to run this app in your local?
First of all, you do need a OpenAI Key 🔒 to utilise the API. 👉 How to apply for a OpenAI Key?
Secondly, run this app up:
Here are the steps to follow:
- Step 1: Install PHP 8.2
- Step 2: Install Composer, which is used to install PHP packages.
- Step 3: Install Symfony CLI
// macOS wget https://get.symfony.com/cli/installer -O - | bash

php bin/console secrets:set OPEN_AI_KEY
Please type the secret value:
>
[OK] Secret "OPEN_AI_KEY" encrypted in "config/secrets/dev/"; you can commit it.
# To view the secrets that you just set
php bin/console secrets:list --reveal
