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

--

so bottom line api more determining data wish send (and receive) how set system

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod...
