Practice

1. Which command do you use to start creating a new Astro project?

easy

A. astro init

B. npm install astro

C. npm run dev

D. npm create astro@latest

Solution

1. Step 1: Understand how to create a new Astro project

   The official way to start a new Astro project is by running npm create astro@latest, which sets up the project files.

2. Step 2: Differentiate from other commands

   npm install astro installs a package but doesn't create a project; npm run dev runs the project; astro init is not a valid command.

3. Final Answer:

   npm create astro@latest -> Option D

4. Quick Check:

   Create new Astro project = npm create astro@latest [OK]

Hint: Use 'npm create astro@latest' to start a new project [OK]

Common Mistakes:

• Using 'npm install astro' to create a project
• Trying 'astro init' which is invalid
• Running 'npm run dev' before creating the project

2. Which command installs the dependencies inside your Astro project folder?

easy

A. npm run dev

B. npm create astro@latest

C. npm install

D. npm start

Solution

1. Step 1: Identify the command for installing dependencies

   After creating the project, you run npm install inside the project folder to download all needed packages.

2. Step 2: Understand other commands' purposes

   npm create astro@latest creates the project; npm run dev runs the development server; npm start is not standard for Astro.

3. Final Answer:

   npm install -> Option C

4. Quick Check:

   Install dependencies = npm install [OK]

Hint: Run 'npm install' to get all project dependencies [OK]

Common Mistakes:

• Running 'npm create astro@latest' again to install
• Using 'npm start' which is not standard here
• Skipping dependency installation before running dev server

3. What happens when you run npm run dev inside your Astro project folder?

medium

A. It installs all project dependencies.

B. It starts a local development server to preview your site.

C. It builds the project for production.

D. It creates a new Astro project.

Solution

1. Step 1: Understand the purpose of 'npm run dev'

   This command starts a local server that watches your files and shows your site live as you build it.

2. Step 2: Differentiate from other commands

   npm install installs dependencies; creating a project is done by npm create astro@latest; building for production uses npm run build.

3. Final Answer:

   It starts a local development server to preview your site. -> Option B

4. Quick Check:

   npm run dev = start dev server [OK]

Hint: Use 'npm run dev' to preview your site live [OK]

Common Mistakes:

• Confusing 'npm run dev' with installing dependencies
• Thinking it creates a new project
• Assuming it builds production files

4. You ran npm run dev but your site does not show up in the browser. What is the most likely cause?

medium

A. You did not install dependencies with npm install.

B. You forgot to create the project with npm create astro@latest.

C. You ran npm run dev outside the project folder.

D. You need to run npm start instead.

Solution

1. Step 1: Check dependency installation

   If dependencies are missing because npm install was not run, the dev server may fail or not load properly.

2. Step 2: Consider other causes

   Running npm run dev outside the project folder or forgetting to create the project can cause errors, but missing dependencies is the most common cause.

3. Final Answer:

   You did not install dependencies with npm install. -> Option A

4. Quick Check:

   Missing dependencies = run npm install first [OK]

Hint: Always run 'npm install' before 'npm run dev' [OK]

Common Mistakes:

• Skipping 'npm install' after project creation
• Running dev server outside project folder
• Trying 'npm start' which is not standard

5. You want to create a new Astro project, install dependencies, and start the development server in the fewest commands possible. Which sequence is correct?

hard

A. npm create astro@latest -> npm install -> npm run dev

B. npm install -> npm create astro@latest -> npm run dev

C. npm create astro@latest -> npm run dev

D. npm run dev -> npm create astro@latest -> npm install

Solution

1. Step 1: Create the project first

   You must first run npm create astro@latest to generate the project files.

2. Step 2: Install dependencies before running dev server

   After creation, run npm install to get all packages, then npm run dev to start the server.

3. Step 3: Understand why other sequences fail

   Running npm run dev before installing dependencies or creating the project causes errors; installing before creating is illogical.

4. Final Answer:

   npm create astro@latest -> npm install -> npm run dev -> Option A

5. Quick Check:

   Create -> Install -> Dev server = correct order [OK]

Hint: Remember: create project, install dependencies, then run dev [OK]

Common Mistakes:

• Skipping 'npm install' after project creation
• Running dev server before project exists
• Installing before creating the project
