Domain entities are called entries within the Streams platform. Please familiarize yourself with streams before getting started with entries.

Defining Entries

Flat File Storage

You can define entry data using the default flat-file database within the streams/{stream}/ directory where stream is the stream handle to which the entry belongs.

Like streams, entry filenames serve as an id called a handle, which you can use to reference the entry the same as you would its numeric ID. JSON is the default data format, though other data formats are available through source configuration.

// streams/contacts/ryan_thompson.json
    "name": "Ryan Thompson",
    "email": "[email protected]",
    "company": "fundamental_llc"

Basic Usage

Expanding Fields

You can use the expand function to return expanded field values.

foreach (Streams::entries('family')->where('relation', 'brother')->get() as $sibling) {
    // The raw value.

     // An email link.

Entry Repositories

Repositories are responsible for encapsulating storage and querying logic.

Entry repositories are accessed via the Streams facade:

foreach (Streams::repository('contacts')->all() as $entry) {
    $entry->name; // The name value.

You can also retrieve specific entries by their handle:

$entry = Streams::repository('contacts')->find('ryan_thompson');

Updating Entries

Updating entries is easy. You can, of course, directly modify the flat-file data. But let's take a look at a couple of other methods.

Entry Repositories

Like the operations above, you can use the Stream facade to save and delete entries.

$entry->name = "Mr Ryan Thompson";


Storage Methods

You can use a few storage methods directly on the entry instance itself.

$entry->name = "Mr Ryan Thompson";

$entry->save(); // Returns bool.
$entry->delete(); // Returns bool.

Entry Objects

Working with entry objects is the same regardless of the source of the stream entries. With this, you can quickly scaffold projects using flat-file storage, then easily migrate stream schema into a database and manage entries there with zero code changes.

Configuring Abstracts

Entry abstracts are configured on the domain model.

Expanding Entry Values

Each field type provides it's own expanded data type besides the primary accessor and mutator casting. Please refer to individual [field type documentation] to learn more about their expanded values.

Use the expand method and specify the handle of the field to expand the value of:

$entry = Streams::repository('contacts')->find('ryan_thompson');

$entry->expand('email')->mailto($entry->name); // Mailto link with custom link text.
