1- Configure repository

Clone the repository

git clone https://github.com/TomasS-R/chatbotWhatsAppApiBusiness.git

Once we have cloned or downloaded the repository to our local environment we install everything contained in the package.json file with:

npm install

This will install all the corresponding dependencies so that it works without any problem.

Configure the .env file

The repository contains the file ExampleEnv.txt what we must do is to change the name to this:

ExampleEnv.txt

to the name

.env

This way fly.io will read this file correctly when configuring the environment variables.
