Laravel App Runs on Local Server

This flow shows the steps to install Laravel using Composer, from checking Composer to running the Laravel app locally.

Execution Sample

Laravel

composer create-project laravel/laravel myapp
cd myapp
php artisan serve

This code installs Laravel in a folder named 'myapp', moves into it, and starts the local server.

Execution Table

Step	Command	Action	Result
1	composer create-project laravel/laravel myapp	Composer downloads Laravel files	Laravel project folder 'myapp' created with all files
2	cd myapp	Change directory to project folder	Current folder is now 'myapp'
3	php artisan serve	Start Laravel development server	Server runs at http://127.0.0.1:8000
4	Access http://127.0.0.1:8000 in browser	Browser loads Laravel welcome page	Laravel app is running and visible
5	Exit	Stop server or close terminal	Laravel app stops running

💡 Laravel app runs until server is stopped or terminal closed

Variable Tracker

Variable	Start	After Step 1	After Step 2	After Step 3	Final
Current Folder	User home or terminal start	User home or terminal start	'myapp' folder	'myapp' folder	'myapp' folder
Laravel Files	None	Downloaded in 'myapp'	Available in 'myapp'	Available in 'myapp'	Available in 'myapp'
Server Status	Stopped	Stopped	Stopped	Running at 127.0.0.1:8000	Stopped after exit

Key Moments - 3 Insights

Why do we need to check if Composer is installed before running the create-project command?

Composer is the tool that downloads Laravel files. If it's not installed, the command will fail. See Step 1 in execution_table where Composer downloads files.

What happens if you run 'php artisan serve' outside the Laravel project folder?

The command won't find the Laravel files and will give an error. Step 2 shows changing into the project folder before running the server in Step 3.

Why do we use 'composer create-project' instead of just downloading Laravel manually?

Composer handles downloading all Laravel files and dependencies automatically, ensuring the project is set up correctly as shown in Step 1.

Visual Quiz - 3 Questions

Look at the execution_table, what is the result after running 'composer create-project laravel/laravel myapp'?

A Laravel project folder 'myapp' created with all files

B Server runs at http://127.0.0.1:8000

C Current folder is now 'myapp'

D Laravel app stops running

💡 Hint

Check Step 1 in the execution_table for the result of the create-project command

At which step does the Laravel development server start running?

A Step 1

B Step 3

C Step 2

D Step 4

💡 Hint

Look at the 'Action' and 'Result' columns in execution_table for when the server starts

If you forget to change directory into 'myapp' before running 'php artisan serve', what will happen?

A Laravel app will run normally

B Composer will download Laravel files again

C The server command will fail because Laravel files are not found

D The terminal will automatically change directory

💡 Hint

Refer to key_moments about running 'php artisan serve' outside the project folder

Full Transcript

To install Laravel using Composer, first open your terminal and check if Composer is installed. If not, install Composer. Then run the command 'composer create-project laravel/laravel myapp' to download Laravel files into a folder named 'myapp'. Next, change your directory to 'myapp' using 'cd myapp'. Start the Laravel development server by running 'php artisan serve'. This will launch the app locally at http://127.0.0.1:8000. You can open this address in your browser to see the Laravel welcome page. The server will keep running until you stop it or close the terminal.
