silex-mongodb-provider

Silex MongoDB Service Provider - integrates Mongo PHP Library with Silex 2.x

Requirements

• PHP 5.6+ || 7.0+
• php-mongodb (ext-mongodb)
• Silex 2.x

Installation

Configuration & Usage

Connection uri defaults to mongodb://localhost:27017. For additional resources about configuration/setup options and library usage, take a look at the Resources section.

Zero Configuration

Container setup

NOTE!

I omit use Corllete\SilexMongoDB\Provider\MongoDBServiceProvider; line in all of the examples below for a sake of simplicity.

Usage

Provide some options

Container setup

Usage

Multiple Connections

Container setup

WARNING!

You have to apply rawurlencode() username and password when used directly in the uri string

Usage

Explicit set default connection via connection name reference

Container setup

Usage

Explicit set default connection - connection label

Container setup

Usage

Assemble uri

Container setup

Few things to keep in mind here:

• host and port are required in this configuration scenario, no defaults fallback
• if you provide username, password is required
• database is optional in all cases

Container namespace

By default, this service provider is registered in mongodb.* and mongodbs.* container namespace. While reserved by the core parameters and core services namespace is something everyone must live with, I don't feel occupying namespace (e.g. mongodb) from thrid party service providers is a good practice. Exactly this bad feeling made me implement feature (that I personally call) service provider namespace. The logic behind it is extremely simple - you provide single and multi namespace values (following the logic of core DoctrineServiceProvider which takes db and dbs namespaces) to the service provider constructor as respectively first and second argument.

It's a 'behind the scenes' feature, you may or may not use it but most important - you have a choice.

Example - occupy db and dbs namespaces - given there is no registered DoctrineServiceProvider, no space for RDBMS!

Usage

Example - override only single connection namespace to db

Usage

MongoDB Client service factory

If you, for any reason (unknown to me!) decide you need to manually create \MongoDB\Client instance, you may use the registered with MongoDBServiceProvider factory callable.

Factory callable accepts one argument - array of connection configuration options, as they are passed via mongodb.options to the service provider. If no configuration options are passed, $app['mongodb.default_options'] will be used (and you may override it!).

Configuration options, service parameters and services reference

Configuration options

The following describes the options passed to the register() container method (see examples section).

Single connection options

mongodb is the single connection configuration namespace, it may be overridden (see Namespace section). If this happens, you have to substitute it in the examples below.

• mongodb.default_options (array) - options used for zero configuration (or the factory service) in same format as mongodb.options. You may override it directly in your bootstrap code to change default behaviour. The default value of this option:

• mongodb.options (array) - same format as mongodb.default_options, set your single connection options - more details about uri format, uri and driver options in MongoDB PHP library \MongoDB\Client documentation and Official MongoDB conection uri documentation.

Multi connection options

mongodbs is the multi connection configuration namespace, it may be overridden (see Namespace section). If this happens, you have to substitute it in the examples below.

• mongodbs.options (array) - array of mongodb.options in format LABEL => mongodb.options. More details in the examples section.
• mongodbs.default (string) - connection label, defined in mongodbs.options to be set as default (thus retrieved with $app['mongodb']).

Services

Retrievable in your code via $app['SERVICE_NAME'];

• mongodb (\MongoDB\Client) - default mongodb client. The name of this service depends on the single connection configuration namespace.
• mongodbs (Pimple\Container) - contains all mongodb clients registered with the service provider. Retrieve them by label. The name of this service depends on the multi connection configuration namespace.

Internal

• mongodb.factory (callable) - \MongoDB\Client factory service. The name of this service depends on the single connection configuration namespace.
• mongodb.options.init (callable) - used internally to one-time prepare the configuration array. The name of this service depends on the single connection configuration namespace.

Parameters

Retrieve or override in your code via $app['PARAMETER_NAME'];

• mongodb.default_options (array) - set to override zero configuration setup & mongodb client factory default behaviour. More details in Configuration options section. The name of this parameter depends on the single connection configuration namespace.

Tests

Run phpunit test after composer install

You may also print the coverage

Gotchas

• s is important! Be sure not to mess up mongodb.options and mongodbs.options
• It seems your service provider configuration is not found? In most cases you did the following - you have changed the service provider namespace, but you have provided the default namespace configuration options (e.g. mongodb.options instead yourNamespace.options)
• If you see \LogicException after you call the mongodb client in your code, check your service provider configuration - most probably you have provided both mongodb.options and mongodbs.options configuration parameters (which is clearly illegal).
• You have set 'default' connection in multi connection setup, but it is NOT the default one! Well, hardly, but you may double check if you are using both methods of setting default connection - connection labeled 'default' and mongodbs.default = connection_name. Connection label has higher precedence, so in the previous scenario, 'default' labeled connection will be the one returned by $app['mongodb'] and $app['mongodbs']['default']
