NAME

Twitter::API::Migration - Migration support Net::Twitter/::Lite users

VERSION

version 0.0107

DESCRIPTION

Twitter::API is a rewrite of Net::Twitter. It's leaner, lighter, faster—fewer dependencies, less baggage.

Migrating from Net::Twitter

Twitter::API requires a minimum perl version of 5.14.1. Make sure you have that.

If you're using Net::Twitter in a very standard way, the switch is easy.

my $client = Net::Twitter->new(
	traits => [ qw/API::RESTv1_1 OAuth RetryOnError/ ],
	consumer_key        => $key,
	consumer_secret     => $secret,
	access_token        => $token,
	access_token_secret => $token_secret,
);

Becomes:

my $client = Twitter::API->new_with_traits(
	traits => [ qw/ApiMethods RetryOnError/ ],
	consumer_key        => $key,
	consumer_secret     => $secret,
	access_token        => $token,
	access_token_secret => $token_secret,
);

Differences: =for :list * replace new with new_with_traits * replace trait API::RESTv1_1 with ApiMethods * drop trait OAuth, Twitter::API's core includeds it

Traits

Twitter::API supports the following traits: =for :list * ApiMethods * AppAuth * DecodeHtmlEntities * NormalizeBooleans * RetryOnError * Enchilada

ApiMethods is a direct replacement for Net::Twitter's API::RESTv1_1 trait.

Net::Twitter's InflateObjects trait will be released as a separate distribution to minimize Twitter::API's dependencies.

If you are using the Net::Twitter's WrapResults trait, Twitter::API provides a better way to access the what it provides. In list context, API calls return both the API call results and a Twitter::API::Context object that provides the same accessors and attributes WrapResult provided, including the result accessor.

So, if you had:

my $r = $client->home_timeline;
$r->result;
$r->rate_limit_remaining;

You can change that to:

my ( $result, $context ) = $client->home_timeline;
$result;
$context->rate_limit_remaining;

Or for the smallest change to your code:

my ( undef, $r ) = $client->home_timeline;
$r->result; i            # same as before
$r->rate_limit_remaning; # same as before

However, there is migration support for WrapResult. Call the constructor with option <wrap_result = 1>> and Twitter::API will return the context object, only, for API calls. This should give you the same behavior you had with WrapResult while you modify your code. Twitter::API will warn when this option is used. You may disale warnings with $ENV{TWITTER_API_NO_MIGRATION_WARNINGS} = 1.

If you are using any other Net::Twitter traits, please contact the author of Twitter::API. Additional traits may be added to Twitter::API or released as separate distributions.

If you are using <decode_html_entities = 1>> in Net::Twitter, drop that option and add trait DecodeHtmlEntities. Traits AppAuth and RetryOnError provide the same functionality in Twitter::API as their Net::Twitter counterparts. So, no changes required, there, if you're using them. (Although there is a change to one of AppAuth's methods. See the "OAuth changes" discussion.)

NormalizeBooleans is something you'll probably want. See the NormalizeBooleans documentation.

Enchilda just bundles ApiMethods, NormalizeBooleans, RetryOnError, and DecodeHtmlEntities.

Other constructor options

  • ssl - Drop it; it is no longer necessary. By default, all connections use SSL.

If you are setting useragent_lass and/or useragent_args to customize the user agent, just construct your own pass it to new with <user_agent = $custom_user_agent>>.

If you are using ua to set a custom user agent, the attribute name has changed to usre_agent. So, pass it to new with <user_agent = $custom_user_agent>>.

By default, Twitter::API uses HTTP::Thin as its user agent. You should be able to you any user agent you like, as long as it has a request method that takes an HTTP::Request and returns an HTTP::Response.

If you used clientname, clientver, clienturl, or useragent, see "agent" in Twitter::API and "default_headers" in Twitter::API. If all you're after is a custome User-Agent header, just pass <agent = $user_agent_string>>. It will be used for both User-Agent header and the X-Twitter-Client header on requests. If you want to include your own application version and url, pass <default_headers = \%my_request_headers>>.

OAuth changes

Net::Twitter saved request and access tokens in the client instance as part of the 3-legged OAuth handshake. That was a poor design decision. Twitter::API returns request and access tokens to the caller. It is the caller's responsibility to store are cache them appropriately. Hovever, tansitional support is provided, with client instance storage, so your code can run, unmodified while you make the transition.

The following methods exist only for migration from Net::Twitter and will be removed in a future release. A warning is issued on each call to these methods. To disable the warnings, set $ENV{TWITTER_API_NO_MIGRATION_WARNINGS} = 1.

Documentation for those methods: =for list: * "oauth_request_token" in Twitter::API * "oauth_authentication_url" in Twitter::API * "oauth_authorization_url" in Twitter::API * "oath_access_token" in Twitter::API

If you are using the AppAuth trait, replace request_access_token calls with oauth2_token calls. Method oauth2_token does not set the access_token attribute. Method request_access_token is provided for tranitional support, only. It warns like the OAuth mehods discussed above, and it sets the access_token attribute so existing code should work as expected during migration. It will be removed in a future release.

Migrating from Net::Twitter::Lite

The discussion, above applies for Net::Twitter::Lite with a few exceptions.

Net::Twitter::Lite does not use traits. Change your contructor call from:

my $client = Net::Twitter::Lite::WithAPIv1_1->new(%args);

To:

my $client = Twitter::API->new_with_traits(
    traits => [ qw/ApiMethods/ ],
    %args,
);

If you're using the option wrap_result, see the discussion above about the Net::Twitter WrapResult trait. There is migration support for wrap_result. It will be removed in a future release.
