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 methods to map properties to columns and
define the base SQL query (see example below).
Pass the callable returned by the route handling functions to your Slim or other PSR-7 compatible framework.
<?phpuseDevTheorem\Phaster\{Entities, Prop, QueryOptions};
class Users extends Entities
{
// Return the table to insert/update/delete/select from.// If not implemented, the class name will be used as the table name.protectedfunctiongetTableName(): string
{
return'users';
}
// Return an array which maps properties to writable column names. Returns an// empty array by default, so no properties will be writable if not implemented.protectedfunctiongetMap(): array
{
return [
'username' => 'uname',
'firstName' => 'fname',
'lastName' => 'lname',
'isDisabled' => 'disabled',
'role' => [
'id' => 'role_id',
],
];
}
// Return a list of `Prop` objects, which map properties to readable columns and/or values,// and enable setting a type to cast the column value to, or defining a virtual property// which depends on other columns. See the Prop constructor for the full list of parameters// that can be set. Returns an empty array by default.protectedfunctiongetSelectProps(): array
{
return [
newProp('id', col: 'u.user_id'),
newProp('username', col: 'u.uname'),
newProp('firstName', col: 'u.fname'),
newProp('lastName', col: 'u.lname'),
newProp('isDisabled', col: 'u.disabled', type: 'bool'),
newProp('role.id', col: 'u.role_id'),
newProp('role.name', col: 'r.role_name'),
];
}
// Return a SELECT SQL query (without a WHERE clause) in order to join other tables when// selecting data. If not implemented, mapped columns will be selected from the table// returned by getTableName().protectedfunctiongetBaseQuery(QueryOptions$options): string
{
return"SELECT {$options->getColumns()} FROM users u INNER JOIN roles r ON r.role_id = u.role_id";
}
// Set the default column/direction for sorting selected results. If not implemented,// results will be sorted by the id property in ascending order by default.protectedfunctiongetDefaultSort(): array
{
return ['username' => 'asc'];
}
}If it is necessary to bind parameters in the base query, use getBaseSelect() instead:
useDevTheorem\PeachySQL\QueryBuilder\SqlParams;
// ...protectedfunctiongetBaseSelect(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";
returnnewSqlParams($sql, [321]);
}
// ...<?phpuseMy\DatabaseFactory;
useDevTheorem\Phaster\{Entities, EntitiesFactory};
class MyEntitiesFactory implements EntitiesFactory
{
publicfunctioncreateEntities($class): Entities
{
returnnew$class(DatabaseFactory::getDb());
}
}<?phpuseDevTheorem\Phaster\RouteHandler;
$phaster = newRouteHandler(newMyEntitiesFactory());
