Vue CLI and Project Setup Essentials Quiz Quiz

Assess your understanding of Vue CLI and essential project setup concepts with this targeted quiz. Explore key topics such as initialization commands, configuration files, dependency management, and build tools relevant to modern Vue.js development.

1. Understanding Vue CLI Initialization

   When starting a new Vue project, which command is typically used to initialize a project scaffold with the Vue CLI?

   1. vue setup my-project
   2. vue create my-project
   3. npm start my-project
   4. vue init my-project

   Explanation: The correct command is 'vue create my-project', which initializes a new Vue project using the CLI and guides you through project setup options. 'vue init my-project' is outdated and not part of the latest CLI workflow. 'vue setup my-project' is not a recognized command. 'npm start my-project' is used to start a project, not to initialize it.

2. Purpose of package.json in a Vue Project

   What is the main role of the 'package.json' file in a Vue CLI-generated project?

   1. It manages project dependencies and scripts.
   2. It contains page templates and HTML structure.
   3. It stores compiled source code.
   4. It defines only styling rules for components.

   Explanation: The 'package.json' file primarily manages dependencies, project metadata, and scripts like build or test commands. It does not contain page templates, which are found in Vue component files. It doesn't store compiled code; that is handled by the build output directory. Styling rules are typically defined in separate CSS or Vue files, not in 'package.json'.

3. Selecting Presets During Project Setup

   During Vue CLI project setup, what does choosing a preset with features like Babel, TypeScript, or Linter determine?

   1. The color scheme of the default user interface.
   2. Which tools and configurations are included in the initial project.
   3. The amount of RAM allocated to the project.
   4. How the application is deployed to a server.

   Explanation: Selecting a preset determines which tools and configurations—such as Babel for transpiling, TypeScript for static typing, or Linter for enforcing code style—are included at project creation. It does not influence RAM allocation or the UI color scheme. Application deployment methods are handled separately from preset selection.

4. Role of the vue.config.js File

   In a Vue CLI project, what is the primary function of the 'vue.config.js' file?

   1. It holds the content for static images and media files.
   2. It stores user authentication credentials.
   3. It installs new dependencies automatically.
   4. It allows customization of the project's webpack and development settings.

   Explanation: The 'vue.config.js' file is used to adjust the default build tool configurations, such as webpack settings or dev server options. It does not handle dependency installation, which is managed by package managers. It should never store authentication information. Media files like images are stored in the public or assets directories, not in this configuration file.

5. Running the Local Development Server

   Which script specified in the 'package.json' file is commonly used to launch the local development server for previewing your Vue application?

   1. deploy
   2. serve
   3. preview
   4. install

   Explanation: The 'serve' script is the standard command to start the local development server using the CLI, enabling you to preview and test your application. 'deploy' is typically used for pushing builds to hosting solutions, not for local preview. 'preview' is not a standard command in this context. 'install' is used for downloading dependencies and does not launch the server.
