client.verifyKey().then((isValid) =>
  print(isValid ? 'Your API key is valid.' : 'Your API key is invalid.')

Implementations

Client

The Akismet client comes in two flavors: a first one based on dart:io for server/console applications, and a second one based on dart:html for client/browser applications.

Their usage is the same, but the HTML client is limited by security restrictions in a browser context. Unfortunately, the Akismet service does not support CORS headers. So, the HTML client can't be used directly with the official service.

Server

To be able to use the HTML client, we must rely on a proxy server adding CORS headers to service responses.

This is why a server implementation is provided with this package. To facilitate its usage, a command line interface is available in the bin folder.

From a command prompt, run the cli.dart script:

$ dart bin/cli.dart --help

Starts an Akismet.dart server.

Usage:
    cli.dart [options]

Options:
-a, --address     The address to which to listen.
                  (defaults to "0.0.0.0")

-p, --port        The port on which to listen.
                  (defaults to "3000")

-r, --redirect    The URL to redirect when a request is not handled.
-h, --help        Print this usage information.
