TinyGID

Tiny class to build Global ID (gid://) strings from scalar values.

Usage

gem install tiny_gid or for Bundler: gem "tiny_gid", :require => "gid"

Setting an app name is required. If Rails is installed Rails.application.name is used.

require "gid"

gid.app = "shopify"

gid::Product(123)        # "gid://shopify/Product/123"
gid::ProductVariant(123) # "gid://shopify/ProductVariant/123"
gid::InventoryLevel(123, :inventory_item_id => 456) # "gid://shopify/InventoryLevel/123?inventory_item_id=456"

# Use something besides gid.app for the duration of the block:
gid.app("something-amaaaazing") do
  gid::User(1)  # "gid://something-amaaaazing/User/1"
  gid::Post(99) # "gid://something-amaaaazing/User/99"
end

This will also import the GID class:

gid = GID.new("shopify")
gid::Product(123)        # "gid://shopify/Product/123"

# You don't have to use :: of course ;)
gid.Product(123) # "gid://shopify/Product/123"

If you don't want the (pesky?) gid method you can require: tiny_gid/gid which gives you GID only.

If GID creates a conflict in the top-level namespace use TinyGID:

require "tiny_gid"

TinyGID.app = "shopify"
TinyGID::Product(123) # "gid://shopify/Product/123"

TinyGID.app("something-amaaaazing") do |gid|
  gid::User(1) # "gid://something-amaaaazing/User/1"
end

gid = TinyGID.new("shopify")
gid.Product(123)

Parsing

app, model, id = gid.parse("gid://shopify/Product/123")
app, model, id, params = gid.parse("gid://shopify/Product/123?foo=bar")

params is a Hash

If you just want the scalar ID:

id = gid.to_sc("gid://shopify/Product/123") # "123"
id = gid.to_sc("gid://shopify/Product/123?foo=bar") # "123"

Why Not Use GlobalID‽

GlobalID is nice but it primarily deals with IDs backed by an instance of a class, e.g. Rails model, whereas TinyGID is for scalars.

GlobalID does indeed have version that can be used with scalars but it's a bit verbose and not good for developer productivity:

URI::GID.build(:app => "foo", :model_name => "User", :model_id => "123", :params => { :foo => "bar" })

Don't yah think?

ID Encoding/Escaping

Using application/x-www-form-urlencoded encoding to match GlobalID. Should probably support URL encoding too.

To put that in 21st century speak: spaces will be replaced with + not %20.

Signed Global IDs

No support. Use GlobalID :)
