Bug fix: command hints not displayed after completion of create-next-app

[suwakei]

Problem

When you create a new Next.js project using the create-next-app command, you will normally see the following guidance message at the end of the process.

Success! Created my-app at /path/to/my-app
Inside that directory, you can run several commands:

  npm run dev
    Starts the development server.

  npm run build
    Builds the app for production.

  npm start
    Runs the built app in production mode.

We suggest that you begin by typing:

  cd my-app
  npm run dev

However, with this bug, if you create a project without the --example option (i.e., interactively select TypeScript, Tailwind CSS, etc.),
you will not see this guidance message.

Cause

The cause is that a flag (variable) called hasPackageJson,
which determines whether or not to display the guidance message, has not been updated.

1. The variable hasPackageJson is initialized with false.

let hasPackageJson = false

2. --example Processing if option is specified:

• Download the sample from GitHub.
• Check if package.json exists in the sample and set hasPackageJson to true or false.

if (example) {
  // ...
  hasPackageJson = existsSync(packageJsonPath) // Correctly set here
  // ...
}

3. --example Handle if option is not specified:

• Call the function installTemplate to create a project template containing package.json.
• Problem: Although this installTemplate function creates package.json, its caller does not update the hasPackageJson value.

} else {
  // ...
  await installTemplate({
    // ...
  })
  // *** The process of updating hasPackageJson to true is missing here. ***
}

4. Finally, the process displays a guidance message:

if (hasPackageJson) { //If example is not used, this will be false.
  console.log('Inside that directory, you can run several commands:')
  // ...
}

• The guidance message is displayed only if hasPackageJson is true.

In the case where --example was not used, hasPackageJson remained false, resulting in a bug where the final guidance message was not displayed.

Fix

The fix is quite simple: since the installTemplate function always creates package.json,
add a line that sets hasPackageJson to true immediately after the call completes.

      turbopack,
      rspack,
    })
    +++ hasPackageJson = true
  }

  if (disableGit) {

This fix improves the user experience by ensuring that a consistent and friendly completion message is always displayed,
regardless of how the project was created.
