NAME

    API::Client

ABSTRACT

    HTTP API Thin-Client Abstraction

SYNOPSIS

      package main;
    
      use API::Client;
    
      my $client = API::Client->new(url => 'https://httpbin.org');
    
      # $client->resource('post');
    
      # $client->update(json => {...});

DESCRIPTION

    This package provides an abstraction and method for rapidly developing
    HTTP API clients. While this module can be used to interact with APIs
    directly, API::Client was designed to be consumed (subclassed) by
    higher-level purpose-specific API clients.

THIN CLIENT

    The thin API client library is advantageous as it has complete API
    coverage and can easily adapt to changes in the API with minimal
    effort. As a thin-client superclass, this module does not map specific
    HTTP requests to specific routines, nor does it provide parameter
    validation, pagination, or other conventions found in typical API
    client implementations; Instead, it simply provides a simple and
    consistent mechanism for dynamically generating HTTP requests.
    Additionally, this module has support for debugging and retrying API
    calls as well as throwing exceptions when 4xx and 5xx server response
    codes are returned.

INTEGRATES

    This package integrates behaviors from:

    Data::Object::Role::Buildable

    Data::Object::Role::Stashable

    Data::Object::Role::Throwable

LIBRARIES

    This package uses type constraints from:

    Types::Standard

SCENARIOS

    This package supports the following scenarios:

 building

      # given: synopsis
    
      my $resource = $client->resource('get');
    
      # GET /get
      my $get = $client->resource('get')->dispatch;
    
      # HEAD /head
      my $head = $client->resource('head')->dispatch(
        method => 'head'
      );
    
      # PATCH /patch
      my $patch = $client->resource('patch')->dispatch(
        method => 'patch'
      );
    
      [$get, $head, $patch]

    Building up an HTTP request is extremely easy, simply call the
    "resource" to create a new object instance representing the API
    endpoint you wish to issue a request against.

 chaining

      # given: synopsis
    
      # https://httpbin.org/users
      my $users = $client->resource('users');
    
      # https://httpbin.org/users/c09e91a
      my $user = $client->resource('users', 'c09e91a');
    
      # https://httpbin.org/users/c09e91a
      my $new_user = $users->resource('c09e91a');

      }
    
      package main;
    
      my $hookbin = Hookbin->new;

    This package was designed to be subclassed and provides hooks into the
    client building and request dispatching processes. Specifically, there
    are three useful hooks (i.e. methods, which if present are used to
    build up the client object and requests), which are, the auth hook,
    which should return a Tuple[Str, Str] which is used to configure the
    basic auth header, the base hook which should return a Tuple[Str] which
    is used to configure the base URL, and the headers hook, which should
    return a ArrayRef[Tuple[Str, Str]] which are used to configure the HTTP
    request headers.

 transacting

      # given: synopsis
    
      my $tx1 = $client->resource('patch')->patch(
        json => {active => 1}
      );
    
      # is equivalent to
    
      my $tx2 = $client->resource('patch')->dispatch(
        method => 'patch',
        json => {active => 1}
      );
    
      [$tx1, $tx2]

    An HTTP request is only issued when the "dispatch" method is called,
    directly or indirectly. Those calls return a Mojo::Transaction object
    which provides access to the request and response objects.

 updating

      # given: synopsis
    
      my $tx1 = $client->resource('put')->update(
        json => {active => 1}
      );
    
      # is equivalent to
    
      my $tx2 = $client->resource('put')->dispatch(
        method => 'put',
        json => {active => 1}
      );
    
      [$tx1, $tx2]

    This example illustrates how you might update a new API resource.
