Key Moments - 3 Insights

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

Because the project folder is created with configuration files but no packages installed yet. 'npm install' downloads all needed packages as shown in step 6 of the execution_table.

What happens if you try to run 'npm run dev' before 'npm install'?

The dev server will fail to start because dependencies are missing. Step 7 depends on step 6 completing successfully.

Why do we need to navigate into the project folder before installing?

Because 'npm install' must run inside the project folder to install dependencies for that specific project, as shown in step 5 and 6.

Full Transcript

To create a new Vue project, first open your terminal. Run the command 'npm create vue@latest' to start the project setup wizard. You will be asked to enter a project name and select features. After the project folder is created, navigate into it using 'cd project-name'. Then run 'npm install' to download all necessary packages. Finally, start the development server with 'npm run dev'. Open your browser at the provided URL to see the Vue app running. This process sets up a ready-to-develop Vue project.
