How to Quickly Get Started with a New Laravel Project: Key Areas to Explore

When you inherit a new Laravel project, you may feel unsure where to begin, especially if you are not a seasoned programmer. This article outlines the most important sections of a Laravel codebase to help you get up to speed quickly.

1. Documentation

Documentation can be a lifesaver for a new project. If the project includes a README, wiki, Confluence page, or Google Docs, review it thoroughly, but verify that it is up‑to‑date and complete. If documentation is missing, take the opportunity to create or improve it for the benefit of your team and future developers.

2. composer.json

Composer is the PHP package manager that Laravel has used since version 4. Almost every Laravel project contains a composer.json and a composer.lock at the root. The lock file records the exact versions of all dependencies, while the JSON file lists the required packages.

3. Routes

Routes are the entry points for application functionality. Each route maps a URL to a controller or closure that handles the request. By examining a route and following it to its controller, you can discover the related modules and understand how the feature works. Repeating this process for new routes gradually reveals the overall architecture.

Service providers are the “magic” of Laravel; they bootstrap the framework and its core services. You can find all providers in the app/providers directory, where custom code such as view composers, macros, and configuration tweaks usually resides.

4. Testing

The test suite in the codebase shows how the application is expected to behave and can provide clues about edge‑case handling. However, tests may be missing, outdated, or incomplete, just like documentation.

Writing or improving tests is an excellent way to learn the project, increase code quality, discover bugs, remove dead code, and add coverage for important classes.

5. Useful Tools

For Laravel developers, the Laravel Debugbar by Barry vd. Heuvel is a powerful debugging and profiling tool. It displays routes, controller actions, database queries, execution times, exceptions, and more, making it indispensable for day‑to‑day development.
