Development server in Laravel - Step-by-Step Execution

Concept Flow - Development server

Run 'php artisan serve'

↓

Server starts on localhost:8000

↓

Browser sends HTTP request

↓

Laravel routes request

↓

Controller processes request

↓

Response sent back to browser

↓

Browser displays page

↓

Developer edits code

↓

Refresh browser to see changes

This flow shows how running Laravel's development server handles browser requests and updates during development.

Execution Sample

Laravel

php artisan serve
// Server starts at http://localhost:8000
// Browser requests http://localhost:8000
// Laravel processes and responds
// Developer refreshes browser to see updates

Starts Laravel's built-in server, handles requests, and shows how changes appear after refreshing.

Execution Table

Step	Action	Input/Request	Server Response	Browser Output
1	Run command	'php artisan serve'	Server starts at http://localhost:8000	No output yet
2	Browser request	GET http://localhost:8000	Laravel routes request to controller	Loading page
3	Controller processes	Request data	Generates HTML response	Page HTML received
4	Send response	HTML content	Response sent to browser	Page displayed
5	Developer edits code	Changes in files	No immediate server restart needed	No change yet
6	Browser refresh	Reload http://localhost:8000	Laravel processes updated code	Updated page displayed
7	Exit	Stop server	Server stops running	No server connection

💡 Server stops when developer ends the 'php artisan serve' command.

Variable Tracker

Variable	Start	After Step 2	After Step 4	After Step 6	Final
Server Status	Stopped	Running	Running	Running	Stopped
Browser Page	Blank	Loading	Displayed	Updated Displayed	Closed
Code Changes	None	None	None	Made	Made

Key Moments - 2 Insights

Why don't code changes immediately show in the browser without refreshing?

Because the development server serves the current code only when a request is made. The browser must refresh to send a new request and get updated content, as shown in steps 5 and 6 of the execution_table.

Does the Laravel development server restart automatically when code changes?

No, the server keeps running without restarting. It serves updated code on the next browser request, as seen in step 6 where the browser refresh triggers updated content.

Visual Quiz - 3 Questions

Look at the execution_table, what is the server status after step 2?

A Stopped

B Running

C Restarting

D Error

💡 Hint

Check the 'Server Status' row in variable_tracker after Step 2.

At which step does the browser display the updated page after code changes?

A Step 4

B Step 5

C Step 6

D Step 7

💡 Hint

Look at the 'Browser Page' variable in variable_tracker and the execution_table rows for browser output.

If the developer stops the server, what happens to the browser output?

A Browser shows no server connection

B Browser automatically refreshes

C Page continues to display normally

D Server restarts automatically

💡 Hint

Refer to the exit_note and the last row of execution_table.

Concept Snapshot

Laravel Development Server:
- Run 'php artisan serve' to start server at localhost:8000
- Browser sends requests, Laravel routes and responds
- Code changes require browser refresh to show updates
- Server runs continuously until stopped manually
- No auto-restart on code changes; refresh triggers new response

Full Transcript

The Laravel development server starts when you run 'php artisan serve'. It listens on localhost port 8000. When you open your browser and visit this address, the server receives the request, Laravel routes it to the right controller, and sends back the HTML page. The browser shows this page. If you change your code, the server does not restart automatically. You must refresh the browser to send a new request and see your changes. When you stop the server command, the server stops and the browser can no longer connect.
