Deploying Laravel Applications with the Vapor CLI

Overview of Serverless Deployments

Deploying a modern web application requires more than just moving files to a server. In a serverless ecosystem like Laravel Vapor, deployment involves orchestrating AWS resources, asset compilation, and environment configuration. By using a serverless approach, developers move away from managing hardware and toward a model where the infrastructure scales automatically based on demand. This lesson focuses on the mechanics of pushing your local code to a live staging environment using the Vapor CLI.

Prerequisites

Before running your first deployment, ensure you have the following in place:

• An active Laravel Vapor account linked to an AWS account.
• The Vapor CLI installed globally via Composer.
• A project already initialized with a vapor.yml configuration file.

Key Libraries & Tools

• Laravel Vapor: A serverless deployment platform built specifically for Laravel.
• Vapor CLI: The command-line interface used to interact with your Laravel Vapor dashboard and trigger deployments.
• AWS: The underlying cloud provider that hosts the Lambda functions, databases, and assets.

Code Walkthrough: The Deployment Command

Executing a deployment is straightforward but initiates a complex chain of events. Open your terminal in the root of your project and run:

vapor deploy staging

When you execute this command, the Vapor CLI performs several critical tasks:

1. Asset Preparation: It gathers your CSS and JS assets, often running build scripts to ensure they are production-ready.
2. Compression: The tool packages your entire application into a compressed format suitable for AWS Lambda.
3. Infrastructure Sync: Vapor communicates with AWS to ensure all necessary tags, permissions, and environment variables match your local vapor.yml settings.

You can track this progress in real-time through the terminal or via the Laravel Vapor web dashboard, which provides a visual timeline of each step's duration and status.

Syntax Notes

The vapor deploy command follows a simple pattern: vapor deploy [environment]. By default, Laravel Vapor creates staging and production environments. However, you can create custom environments for specific developers or features. If you have a branch for a specific feature, you might run vapor deploy feature-x to isolate those changes.

Practical Examples: Vanity Domains

Every environment created in Laravel Vapor receives a unique "vanity domain." These are auto-generated URLs (e.g., random-string.vwp.app) that allow you to preview the application immediately after the deployment finishes. This is invaluable for QA testing before pointing a custom production domain to the build.

Tips & Gotchas

• Cold Starts: Initial deployments often take longer because Laravel Vapor must provision new cloud resources for the first time.
• Environment Parity: Always ensure your local .env values required for production are mirrored in the Laravel Vapor dashboard or vapor.yml file to prevent runtime errors after a successful push.
