What you will learn

  • Explain framework boundaries and isolate local component evidence.
  • Validate and authorize before effects and render data deliberately.

  1. Request lifecycle and the service container

    Follow a request through framework boundaries and make dependencies explicit. Use isolated framework components while distinguishing them from a fully booted Laravel application.

  2. Routes, parameters, and generated URLs

    Define route contracts by method, path, parameters, and name. Distinguish matching from authorization and generate links without scattering hard-coded paths across the application.

  3. Controllers, HTTP input, and response ownership

    Keep controllers focused on translating a request into an authorized use case and a coherent response. Make domain dependencies testable without loading real routes or services.

  4. Blade, view data, and safe output

    Render validated data through explicit view contracts. Distinguish escaped Blade echoes from trusted raw HTML and keep templates separate from queries and authorization decisions.

  5. Validation, middleware, and CSRF boundaries

    Reject malformed input and cross-site request forgery without confusing either with authorization. Follow validated data, middleware context, and session token comparison in isolated component examples.

  6. Migrations, Eloquent models, and safe query foundations

    Connect schema rules, model attributes, and parameterized queries using an owned in-memory SQLite fixture. Distinguish migration intent, model convenience, validation, and durable constraints.
