Open Browser -> See App

This flow shows choosing between Vue CLI or Vite, running commands to create the project, installing dependencies, starting the server, and viewing the app in the browser.

Execution Sample

Vue

npm create vite@latest my-vue-app -- --template vue
cd my-vue-app
npm install
npm run dev

This code creates a new Vue project using Vite, installs dependencies, and starts the development server.

Execution Table

Step	Command Run	Action	Result	Output
1	npm create vite@latest my-vue-app -- --template vue	Create project folder and files	Project folder 'my-vue-app' created with Vue template	Success message with instructions
2	cd my-vue-app	Change directory	Inside project folder	No output
3	npm install	Install dependencies	Dependencies installed in node_modules	List of installed packages
4	npm run dev	Start dev server	Dev server running on localhost:5173	Server URL and ready message
5	Open browser at localhost:5173	View app	Vue app loads in browser	Default Vue welcome page displayed
6	Exit	Stop server or close terminal	Dev server stops	No output

💡 Dev server stops when user exits or closes terminal

Variable Tracker

Variable	Start	After Step 1	After Step 3	After Step 4	Final
Project Folder	None	my-vue-app created	my-vue-app with node_modules	my-vue-app with running server	my-vue-app with server stopped
Dependencies	None	None	Installed	Installed	Installed
Dev Server	Off	Off	Off	Running	Off

Key Moments - 3 Insights

Why do we run 'npm install' after creating the project?

Because the project files are created but dependencies are not yet downloaded. 'npm install' downloads and sets up all needed packages as shown in execution_table step 3.

What happens if you open the browser before running 'npm run dev'?

The app won't load because the development server is not running yet. The server starts only after step 4, so the browser needs the server running to show the app.

Why do we choose between Vue CLI and Vite at the start?

Vue CLI and Vite are two different tools to create Vue projects. Choosing one decides the commands and setup flow, as shown in the concept_flow diagram.

Visual Quiz - 3 Questions

Look at the execution_table, what is the state of the dev server after step 3?

A Starting

B Running

C Off

D Stopped

💡 Hint

Check the 'Dev Server' variable in variable_tracker after step 3

At which step does the project folder get created?

A Step 1

B Step 2

C Step 3

D Step 4

💡 Hint

Look at the 'Project Folder' variable in variable_tracker and execution_table step 1

If you skip 'npm install', what will happen when you run 'npm run dev'?

A Dev server runs normally

B Error due to missing dependencies

C Project folder is deleted

D Browser opens automatically

💡 Hint

Consider what 'npm install' does in execution_table step 3 and its effect on dependencies

Concept Snapshot

Vue CLI and Vite setup:
1. Choose Vue CLI or Vite to create your project.
2. Run the create command (e.g., 'npm create vite@latest my-vue-app -- --template vue').
3. Change into project folder and run 'npm install' to get dependencies.
4. Start dev server with 'npm run dev'.
5. Open browser at localhost to see your Vue app running.

Full Transcript

This visual execution shows how to set up a Vue project using Vue CLI or Vite. First, you pick which tool to use. Then you run commands to create the project folder and files. After that, you install dependencies with 'npm install'. Next, you start the development server with 'npm run dev'. Finally, you open your browser to see the Vue app running. The variable tracker shows how the project folder, dependencies, and dev server state change step-by-step. Key moments explain why each step is important. The quiz tests your understanding of the setup process.
