Overview

Jpzip is the Ruby SDK for the jpzip postal-code dataset (jpzip.nadai.dev). The SDK fetches normalized JSON from the CDN, keeps a per-prefix in-memory LRU, and optionally backs that with a user-supplied persistent cache.

Class Method Details

.configure(**opts) ⇒ Object

Override the singleton with a configured Client. Useful when the app wants to share an L2 cache through the module-level helpers.

# File 'lib/jpzip.rb', line 50

def configure(**opts)
  @default_client = Client.new(**opts)
end

.lookup(zipcode) ⇒ Object

Convenience shortcuts delegating to a process-wide default Client. The singleton uses L1 only — for L2 caches construct your own Client.

# File 'lib/jpzip.rb', line 23

def lookup(zipcode)
  default_client.lookup(zipcode)
end

.lookup_all ⇒ Object

end

.meta ⇒ Object

.reset_default_client! ⇒ Object

Replace the singleton — mainly for tests.

.valid_zipcode?(str) ⇒ Boolean

Returns true iff str is a syntactically valid 7-digit zipcode (no network call).

Returns:

  • (Boolean)
