The command "pnpm add -D ${module_name}" is used to add a module as a development dependency to a project using the package manager called "pnpm".

Here's a breakdown of each part of the command:

• "pnpm": This is the command used to interact with the pnpm package manager.
• "add": This keyword tells pnpm that we want to add a new package to the project.
• "-D": This flag or option specifies that we want to add the module as a development dependency rather than a regular dependency. This means that the module will only be used during development and won't be required for the production deployment of the project. The "-D" flag stands for "dev" or "development".
• "${module_name}": This is a placeholder that should be replaced with the actual name of the module you want to add. For example, if you want to add a module called "lodash", you would replace "${module_name}" with "lodash".

So, when you run the command "pnpm add -D lodash", for instance, you are instructing pnpm to add the "lodash" module as a development dependency to your project.
