How to start with Rails API Design and implementation? -

i new rails api implementation. there blog/site/book/tutorial can start off implementing rails api implementation.

something want remember, apart other answer, api series of endpoints - allowing send requests endpoints & receive responses.

what you'll typically find gems & other information api in rails namespaced controller -

in reference railscast on this, you'll find code:

#app/controllers/api/v1/products_controller.rb module api   module v1     class productscontroller < applicationcontroller       class product < ::product         # note: not take consideration create/update actions changing released_on         def as_json(options = {})           super.merge(released_on: released_at.to_date)         end       end        respond_to :json        def index         respond_with product.all       end        def show         respond_with product.find(params[:id])       end        def create         respond_with product.create(params[:product])       end        def update         respond_with product.update(params[:id], params[:product])       end        def destroy         respond_with product.destroy(params[:id])       end     end   end end 

as rails series of modules & classes, api way create module store api controller class inside.

the supporting routes include (as per railscast):

 #config/routes.rb  namespace :api, defaults: {format: 'json'}     scope module: :v1, constraints: apiconstraints.new(version: 1)       resources :products, :other, :controllers     end   end 

as can see, routes literally allow send json requests scoped api controller. endpoints therefore become:

#api/v1/products #api/v1/other #api/v1/controllers
