# Overview

The View package is Quantum's page-level rendering layer.

Use it when you need more than a raw template render: layouts, shared view parameters, asset registration, page caching, and safe default escaping all live here.

## What the package provides

* `Quantum\View\View` for full-page and partial rendering
* `Quantum\View\Factories\ViewFactory` for resolving the shared view instance
* helper functions such as `view()`, `partial()`, and `view_param()`
* `RawParam` for explicitly unescaped values

## When to use it

Use the View package when your request should render a page inside a layout:

```php
view()->setLayout('layouts/main', [
    'css' => [
        '/css/app.css',
    ],
]);

$html = view()->render('pages/home', [
    'title' => 'Dashboard',
    'user' => $user,
]);
```

Use `renderPartial()` when you only need a fragment and do not want layout, asset, debugger, or cache behavior.

## Default rendering behavior

Before a value reaches the renderer, the package HTML-escapes every string parameter recursively.

That applies to:

* direct string params
* arrays containing strings
* object properties containing strings

If you need trusted HTML to pass through unchanged, wrap that value in `RawParam` or create it with `raw_param()`.

## Important constraints

* Full `render()` requires a layout. If no layout is set, it throws a `ViewException`.
* The factory returns a shared `View` instance, so params, layout state, and layout asset definitions continue across helper calls in the same container lifecycle.
* `getContent()` returns the body from the most recent full `render()`. Partial renders keep that previous full-render content in place.
* The package delegates template lookup and adapter selection to the Renderer package.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://quantumphp.gitbook.io/docs/packages/view/overview.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
