At what stage of development is the connection to the project made?

Connecting to a project in Node.js usually occurs during the environment setup and project initialization. This includes:

• Initializing the project with npm init or yarn init.
• Installing necessary dependencies via a package manager.
• Importing or including modules and libraries in source files.

Thus, connecting to the project happens at the initial stage of development when you prepare the environment and structure for further work with the code.
