Componenta HTTP Emitter
=======================

[](#componenta-http-emitter)

PSR-7 response emitter for Componenta HTTP applications. It sends status, headers, and body content to PHP output.

Use this package at the outer HTTP entry point after the PSR-15 pipeline has produced a `ResponseInterface`.

Boundary
--------

[](#boundary)

This package only emits an already built response. It does not build responses, create server requests, or run middleware. Use `componenta/http-responder` for response creation and `componenta/app-http` for the HTTP runtime pipeline.

Installation
------------

[](#installation)

```
composer require componenta/http-emitter
```

`Componenta\Http\EmitterConfigProvider` is exposed through Composer metadata.

Public API
----------

[](#public-api)

`EmitterInterface::emit(ResponseInterface $response): void` emits a response. `Emitter` is the default implementation.

```
use Componenta\Http\EmitterInterface;

/** @var EmitterInterface $emitter */
$emitter->emit($response);
```

`Emitter` accepts an optional chunk size:

```
$emitter = new Componenta\Http\Emitter(chunkSize: 16_384);
```

`EmitStrategy` controls body emission:

CaseMeaning`Full`Emit the full response body.`Partial`Emit a range response body.`NoBody`Emit headers without a body.`EmitterException` is thrown for emitter-level failures.

Runtime Behavior
----------------

[](#runtime-behavior)

Before emitting, `Emitter` checks that headers have not already been sent and clears active output buffers. Then it chooses a strategy from the response status and headers:

StrategyWhen it is used`NoBody`Informational statuses, `204`, `304`, `416`, or unsatisfiable `Content-Range`.`Partial`Status `206` with a `Content-Range` header.`Full`All other responses.For full responses, the emitter adds `Content-Length` when the stream size is known and the header is missing. For seekable streams with known size it also adds `Accept-Ranges: bytes`. Bodies are streamed in chunks and stop early if the client disconnects.

For partial responses, a valid `Content-Range` controls the emitted byte range when the body stream is seekable. If the range cannot be parsed or the stream is not seekable, the emitter falls back to emitting the full body that is present in the response.

Configuration
-------------

[](#configuration)

The config provider registers `Emitter` and aliases `EmitterInterface` to it. Applications normally receive the emitter from the container.

Related Packages
----------------

[](#related-packages)

- [`componenta/app-http`](../app-http/README.md) uses the emitter in the HTTP runtime.
- [`componenta/http-responder`](../http-responder/README.md) builds PSR-7 responses.
