Yourub

Yourub is a gem for searching YouTube videos using the YouTube Data API v3.

Installation

Add this line to your application's Gemfile:

gem 'yourub'

And then execute:

$ bundle

Or install it yourself as:

$ gem install yourub

Usage

Get a developer key as explained here After that, you have 2 ways to use the client. If you want to use it in your rails app, create a app/config/yourub.yml file as follow:

yourub_defaults: &yourub_defaults
  developer_key: 'YoUrDevEl0PerKey'
  application_name: "yourub"
  application_version: "0.2"
  log_level: WARN

development:
  <<: *yourub_defaults

production:
  <<: *yourub_defaults

test:
  <<: *yourub_defaults

If you want to use it from the console, or in another program, you can simply pass an hash containing the needed options. Change 'yourub' with the name of your application.

options = { developer_key: 'mySecretKey',
             application_name: 'yourub',
             application_version: 2.0,
             log_level: 3 }

client = Yourub::Client.new(options)

Examples

search always requires a non-empty :query. Optional filters narrow results.

Search by text only:

client.search(query: "aliens") do |v|
  puts v
end

Recent sports-related videos in Germany (category is matched by name, see below):

client.search(query: "highlights", country: "DE", category: "sports", order: "date") do |v|
  puts v
end

Available parameters

:query — Required. Non-empty string (after stripping whitespace).

:country — Optional. One or more ISO 3166-1 alpha-2 codes, e.g. "US" or "IT,DE". Codes are validated against Yourub::CountryCodes::ISO_3166_1_ALPHA2 (also exposed as Yourub::Validator::COUNTRIES / client.countries).

:category — Optional. If the name of a category is set, Yourub resolves a category_id from the name: it calls list_video_categories, (cached on the client), finds the first item whose title contains your string (case-insensitive). If the name does not match any category, ArgumentError lists id: title lines of the available categories.

:count_filter — Optional hash, e.g. { views: ">= 100" } or { views: "== 600" } (applied after fetching full video resources).

:max_results — Optional integer from 1 to 50.

:order — Optional. One of: date, rating, relevance, title, videoCount, viewCount. Default relevance.

Methods

search — Runs a YouTube search and yields each video hash that passes optional filters. Requires :query and typically a block.

client.search(query: "space missions") { |v| puts v["id"] }

get — Fetches one video’s metadata (snippet + statistics).

client.get("G2b0OIkTraI")

list_video_categories

Calls YouTube videoCategories.list using only regionCode (via region_code:). The API does not use category IDs in this helper; you pass an ISO 3166-1 alpha-2 region when you want that country’s category list.

region_code: Optional. If omitted or blank, the request is sent without regionCode, which matches the documented default catalog (United States).

hl: Optional. Sets the hl query parameter so snippet titles in the response use the requested locale (e.g. Spanish labels for Spain).

Caching: Responses are cached per client instance, keyed by region_code and hl, because category metadata changes rarely. Repeat calls with the same arguments return the same in-memory result without another HTTP request.

Return value: A Google::Apis::YoutubeV3::VideoCategoryListResponse (from google-apis-youtube_v3). Use #items to iterate categories (each has #id and #snippet).

client = Yourub::Client.new(options)

# Default catalog (documented as US when region is not specified)
us_like = client.list_video_categories

# Explicit region
de_categories = client.list_video_categories(region_code: "DE")

# Region + localized labels
es_labels = client.list_video_categories(region_code: "ES", hl: "es")

flush_video_categories_cache!

Clears all cached list_video_categories results for this client. Call this if you need to force a fresh fetch (e.g. after a long-lived process or for tests).

client.flush_video_categories_cache!
