Overview

This class is the core and low level API for the Parse SDK REST interface that is used by the other components. It can manage multiple sessions, which means you can have multiple client instances pointing to different Parse Applications at the same time. It handles sending raw requests as well as providing Request/Response objects for all API handlers. The connection engine is Faraday, which means it is open to add any additional middleware for features you'd like to implement.

Constructor Details

#initialize(opts = {}) ⇒ Client

Create a new client connected to the Parse Server REST API endpoint.

Parameters:

  • opts (Hash) (defaults to: {}) —

    a set of connection options to configure the client.

Options Hash (opts):

  • :server_url (String) —

    The server url of your Parse Server if you are not using the hosted Parse service. By default it will use ENV if available, otherwise fallback to Protocol::SERVER_URL.

  • :app_id (String) —

    The Parse application id. Defaults to ENV.

  • :api_key (String) —

    Your Parse REST API Key. Defaults to ENV.

  • :master_key (String) —

    The Parse application master key (optional). If this key is set, it will be sent on every request sent by the client and your models. Defaults to ENV.

  • :logging (Boolean, Symbol) —

    Controls request/response logging.

    • true - Enable logging at :info level
    • :debug - Enable verbose logging with headers and body content
    • :warn - Only log errors and warnings
    • false or nil - Disable logging (default) This configures both the new Middleware::Logging middleware and the legacy Middleware::BodyBuilder logging.
  • :logger (Logger) —

    A custom logger instance for request/response logging. Defaults to Logger.new(STDOUT) if not specified.

  • :adapter (Object) —

    The connection adapter. By default it uses :net_http_persistent for connection pooling. Set connection_pooling: false to use the standard Faraday.default_adapter (Net/HTTP) instead.

  • :connection_pooling (Boolean, Hash) —

    Controls HTTP connection pooling. Defaults to true, using the :net_http_persistent adapter for improved performance through connection reuse. Set to false to disable pooling and create a new connection for each request. This option is ignored if :adapter is explicitly specified. Pass a Hash to enable pooling with custom configuration:

    • :pool_size [Integer] - Number of connections per thread (default: 1)
    • :idle_timeout [Integer] - Seconds before closing idle connections (default: 5)
    • :keep_alive [Integer] - HTTP Keep-Alive timeout in seconds @example Custom connection pooling Parse.setup( connection_pooling: { pool_size: 5, idle_timeout: 60, keep_alive: 60 } )
  • :cache (Moneta::Transformer, Moneta::Expires, Parse::Cache::Redis, String) —

    A caching adapter of type Moneta::Transformer or Moneta::Expires that will be used by the caching middleware Middleware::Caching. You can also pass a redis:// URL string (an internal Moneta-Redis store will be built for you) or a Parse::Cache::Redis wrapper, which adds a connection pool and automatic namespace forwarding. Caching queries and object fetches can help improve the performance of your application, even if it is for a few seconds. Only successful GET object fetches and non-empty result queries will be cached by default. You may set the default expiration time with the expires option. At any point in time you may clear the cache by calling the #clear_cache! method on the client connection. See Moneta.

  • :expires (Integer) —

    Sets the default cache expiration time (in seconds) for successful non-empty GET requests when using the caching middleware. The default value is 3 seconds. If :expires is set to 0, caching will be disabled. You can always clear the current state of the cache using the clear_cache! method on your Parse::Client instance.

  • :cache_namespace (String) —

    Optional prefix applied to every cache key. Useful when two Parse apps share one Redis instance and would otherwise collide on identical paths (e.g. mk:/classes/Song/abc). Keys become <namespace>:<existing-prefix>:<url>, so a SCAN <namespace>:* evicts a whole app cleanly. Defaults to no namespace for backward compatibility — explicit only, never auto-derived from app_id.

  • :faraday (Hash) —

    You may pass a hash of options that will be passed to the Faraday constructor.

  • :live_query_url (String) —

    The WebSocket URL for Parse LiveQuery server (e.g., "wss://your-parse-server.com"). If not specified, falls back to ENV. LiveQuery enables real-time subscriptions to changes in Parse objects. @example Enable LiveQuery Parse.setup( server_url: "https://your-server.com/parse&quot;, application_id: "YOUR_APP_ID", api_key: "YOUR_API_KEY", live_query_url: "wss://your-server.com" )

  • :live_query (Hash) —

    Advanced LiveQuery configuration options. Pass a hash with custom settings for the LiveQuery client.

    • :url [String] - WebSocket URL (alternative to :live_query_url)
    • :auto_reconnect [Boolean] - Auto-reconnect on disconnect (default: true)

Raises:

  • Parse::Error::ConnectionError if the client was not properly configured with required keys or url.

  • ArgumentError if the cache instance passed to the :cache option is not of Moneta::Transformer or Moneta::Expires

.setup(opts = {}) { ... } ⇒ Client

Setup the a new client with the appropriate Parse app keys, middleware and options.

Examples:

Parse.setup app_id: "YOUR_APP_ID",
            api_key: "YOUR_REST_API_KEY",
            master_key: "YOUR_MASTER_KEY", # optional
            server_url: 'https://localhost:1337/parse' #default

Parameters:

  • opts (Hash) (defaults to: {}) —

    a set of connection options to configure the client.

Options Hash (opts):

  • :server_url (String) —

    The server url of your Parse Server if you are not using the hosted Parse service. By default it will use ENV if available, otherwise fallback to Protocol::SERVER_URL.

  • :app_id (String) —

    The Parse application id. Defaults to ENV.

  • :api_key (String) —

    Your Parse REST API Key. Defaults to ENV.

  • :master_key (String) —

    The Parse application master key (optional). If this key is set, it will be sent on every request sent by the client and your models. Defaults to ENV.

  • :logging (Boolean, Symbol) —

    Controls request/response logging.

    • true - Enable logging at :info level
    • :debug - Enable verbose logging with headers and body content
    • :warn - Only log errors and warnings
    • false or nil - Disable logging (default) This configures both the new Middleware::Logging middleware and the legacy Middleware::BodyBuilder logging.
  • :logger (Logger) —

    A custom logger instance for request/response logging. Defaults to Logger.new(STDOUT) if not specified.

  • :adapter (Object) —

    The connection adapter. By default it uses :net_http_persistent for connection pooling. Set connection_pooling: false to use the standard Faraday.default_adapter (Net/HTTP) instead.

  • :connection_pooling (Boolean, Hash) —

    Controls HTTP connection pooling. Defaults to true, using the :net_http_persistent adapter for improved performance through connection reuse. Set to false to disable pooling and create a new connection for each request. This option is ignored if :adapter is explicitly specified. Pass a Hash to enable pooling with custom configuration:

    • :pool_size [Integer] - Number of connections per thread (default: 1)
    • :idle_timeout [Integer] - Seconds before closing idle connections (default: 5)
    • :keep_alive [Integer] - HTTP Keep-Alive timeout in seconds @example Custom connection pooling Parse.setup( connection_pooling: { pool_size: 5, idle_timeout: 60, keep_alive: 60 } )
  • :cache (Moneta::Transformer, Moneta::Expires, Parse::Cache::Redis, String) —

    A caching adapter of type Moneta::Transformer or Moneta::Expires that will be used by the caching middleware Middleware::Caching. You can also pass a redis:// URL string (an internal Moneta-Redis store will be built for you) or a Parse::Cache::Redis wrapper, which adds a connection pool and automatic namespace forwarding. Caching queries and object fetches can help improve the performance of your application, even if it is for a few seconds. Only successful GET object fetches and non-empty result queries will be cached by default. You may set the default expiration time with the expires option. At any point in time you may clear the cache by calling the #clear_cache! method on the client connection. See Moneta.

  • :expires (Integer) —

    Sets the default cache expiration time (in seconds) for successful non-empty GET requests when using the caching middleware. The default value is 3 seconds. If :expires is set to 0, caching will be disabled. You can always clear the current state of the cache using the clear_cache! method on your Parse::Client instance.

  • :cache_namespace (String) —

    Optional prefix applied to every cache key. Useful when two Parse apps share one Redis instance and would otherwise collide on identical paths (e.g. mk:/classes/Song/abc). Keys become <namespace>:<existing-prefix>:<url>, so a SCAN <namespace>:* evicts a whole app cleanly. Defaults to no namespace for backward compatibility — explicit only, never auto-derived from app_id.

  • :faraday (Hash) —

    You may pass a hash of options that will be passed to the Faraday constructor.

  • :live_query_url (String) —

    The WebSocket URL for Parse LiveQuery server (e.g., "wss://your-parse-server.com"). If not specified, falls back to ENV. LiveQuery enables real-time subscriptions to changes in Parse objects. @example Enable LiveQuery Parse.setup( server_url: "https://your-server.com/parse&quot;, application_id: "YOUR_APP_ID", api_key: "YOUR_API_KEY", live_query_url: "wss://your-server.com" )

  • :live_query (Hash) —

    Advanced LiveQuery configuration options. Pass a hash with custom settings for the LiveQuery client.

    • :url [String] - WebSocket URL (alternative to :live_query_url)
    • :auto_reconnect [Boolean] - Auto-reconnect on disconnect (default: true)

Yields:

  • the block for additional configuration with Faraday middleware.

Returns:

  • (Client) —

    a new instance of Client

    a hash that will be JSON encoded for the body of this request.

  • uri (String) —

    the uri path for this request.

  • headers (Hash) (defaults to: {}) —

end

#request(method, uri = nil, body: nil, query: nil, headers: nil, opts: {}) ⇒ Parse::Response

Send a REST API request to the server. This is the low-level API used for all requests to the Parse server with the provided options. Every request sent to Parse through the client goes through the configured set of middleware that can be modified by applying different headers or specific options. This method supports retrying requests a few times when a ServiceUnavailableError is raised.

Parameters:

  • method (Symbol) —

    The method type of the HTTP request (ex. :get, :post).

    • This parameter can also be a Request object.
  • uri (String) (defaults to: nil) —

    the url path. It should not be an absolute url.

  • body (Hash) (defaults to: nil) —

    the body of the request.

  • query (Hash) (defaults to: nil) —

    the set of url query parameters to use in a GET request.

  • headers (Hash) (defaults to: nil) —

    additional headers to apply to this request.

  • opts (Hash) (defaults to: {}) —

    a set of options to pass through the middleware stack.

    • :cache [Integer] the number of seconds to cache this specific request. If set to false, caching will be disabled completely all together, which means even if a cached response exists, it will not be used.
    • :use_master_key [Boolean] whether this request should send the master key, if it was configured with Parse.setup. By default, if a master key was configured, all outgoing requests will contain it in the request header. Default true.
    • :session_token [String] The session token to send in this request. This disables sending the master key in the request, and sends this request with the credentials provided by the session_token.
    • :retry [Integer] The number of retrties to perform if the service is unavailable. Set to false to disable the retry mechanism. When performing request retries, the client will sleep for a number of seconds (RETRY_DELAY) between requests. The default value is DEFAULT_RETRIES.

Returns:

Raises:

  • Parse::Error::AuthenticationError when HTTP response status is 401 or 403

  • Parse::Error::TimeoutError when HTTP response status is 400 or 408, and the Parse code is 143 or Response::ERROR_TIMEOUT.

  • Parse::Error::ConnectionError when HTTP response status is 404 is not an object not found error.

    • This will also be raised if after retrying a request a number of times has finally failed.

  • Parse::Error::ProtocolError when HTTP response status is 405 or 406

  • Parse::Error::ServiceUnavailableError when HTTP response status is 500 or 503.

  • Parse::Error::ServerError when the Parse response code is less than 100

  • Parse::Error::RequestLimitExceededError when the Parse response code is Response::ERROR_EXCEEDED_BURST_LIMIT.

    • This usually means you have exceeded the burst limit on requests, which will mean you will be throttled for the next 60 seconds.

  • Parse::Error::InvalidSessionTokenError when the Parse response code is 209.

    • This means the session token that was sent in the request seems to be invalid.
