Phaster is a PSR-7 compatible library for easily making CRUD API endpoints. It enables mapping API fields to columns in the database or from a select query, and implementing custom validation or row modification logic. Built on top of PeachySQL.
composer require devtheorem/phaster
Create a class extending Entities and implement the getMap() method. By default, the table
name will be inferred from the class name, and all mapped columns in this table will be selected.
To join other tables and alter output values, implement the getBaseQuery() and getSelectProps() methods.
Pass the callable returned by the route handling functions to your Slim or other PSR-7 compatible framework.
<?php
use DevTheorem\Phaster\{Entities, Prop, QueryOptions};
class Users extends Entities
{
protected function getMap(): array
{
// map properties to columns in Users table
return [
'username' => 'uname',
'firstName' => 'fname',
'lastName' => 'lname',
'isDisabled' => 'disabled',
'role' => [
'id' => 'role_id',
],
];
}
protected function getSelectProps(): array
{
// map additional properties for selecting/filtering and set output options
return [
new Prop('id', col: 'u.user_id'),
new Prop('isDisabled', col: 'u.disabled', type: 'bool'),
new Prop('role.id', col: 'u.role_id'),
new Prop('role.name', col: 'r.role_name'),
];
}
protected function getBaseQuery(QueryOptions $options): string
{
return "SELECT {$options->getColumns()}
FROM Users u
INNER JOIN Roles r ON r.role_id = u.role_id";
}
protected function getDefaultSort(): array
{
return ['username' => 'asc'];
}
}If it is necessary to bind parameters in the base query, use getBaseSelect instead:
use DevTheorem\PeachySQL\QueryBuilder\SqlParams;
// ...
protected function getBaseSelect(QueryOptions $options): SqlParams
{
$sql = "WITH num_orders AS (
SELECT user_id, COUNT(*) as orders
FROM Orders
WHERE category_id = ?
GROUP BY user_id
)
SELECT {$options->getColumns()}
FROM Users u
INNER JOIN num_orders n ON n.user_id = u.user_id";
return new SqlParams($sql, [321]);
}
// ...<?php
use My\DatabaseFactory;
use DevTheorem\Phaster\{Entities, EntitiesFactory};
class MyEntitiesFactory implements EntitiesFactory
{
public function createEntities($class): Entities
{
return new $class(DatabaseFactory::getDb());
}
}<?php
use DevTheorem\Phaster\RouteHandler;
$phaster = new RouteHandler(new MyEntitiesFactory());
$app->get('/users', $phaster->search(Users::class));
$app->get('/users/{id}', $phaster->getById(Users::class));
$app->post('/users', $phaster->insert(Users::class));
$app->put('/users/{id}', $phaster->update(Users::class));
$app->patch('/users/{id}', $phaster->patch(Users::class));
$app->delete('/users/{id}', $phaster->delete(Users::class));GET https://example.com/api/users?q[firstName]=Ted&q[isDisabled]=0&fields=id,username,role
