Next.js Codebase Analysis <> create-next-app <> index.ts explained — Part 1.4

In the previous article, we logged the program variable and saw some json. In this article, let’s understand how to access an option value passed, specifically program.resetPreferences

Let’s modify the log to print program.resetPreferences

Access options passed in CLI:

1. Add the following as your first line in run():

console.log("program.resetPreferences:", program.resetPreferences);

1. Build the create-next-app

npm run build

1. Run the following command

npx create-my-app --reset-preferences

You pass –reset-preferences option to the cli

Conclusion:

So, to find out if any of the options you configured using Commander are passed in the CLI, you can access the flag using camelCase.

Example:

program.useNpm
program.usePnpm
program.resetPreferences
