rails api REST

shared by 張 旭 on 05 Dec 16 - No Cached
  • designing and implementing a REST API in an intentionally simplistic task management web application, and will cover some best practices to ensure maintainability of the code.
  • each individual request should have no context of the requests that came before it.
  • each request that modifies the database should act on one and only one row of one and only one table
  • ...10 more annotations...
  • The resource endpoints should return representations of the resource as data, usually XML or JSON.
  • POST for create, PUT for update, PATCH for upsert (update and insert).
  • an existing API should never be modified, except for critical bugfixes
  • Rather than changing existing endpoints, expose a new version
  • using unique database ids in the route chain allows users to access short routes, and simplifies resource lookup
  • while exposing internal database ids to the consumer and requiring the consumer to maintain a reference to ids on their end
  • The downfall is longer nested routes
  • require reauthentication on a per-request level
  • Devise.secure_compare helps avoid timing attacks
  • Defensive programming is a software design principle that dictates that a piece of software should be designed to continue functioning in unforeseen circumstances.

Serverless Architectures - 0 views

development architecture system server backend

shared by 張 旭 on 12 Jul 16 - No Cached
  • Serverless was first used to describe applications that significantly or fully depend on 3rd party applications / services (‘in the cloud’) to manage server-side logic and state.
  • ‘rich client’ applications (think single page web apps, or mobile apps) that use the vast ecosystem of cloud accessible databases (like Parse, Firebase), authentication services (Auth0, AWS Cognito), etc.
  • ‘(Mobile) Backend as a Service’
  • ...33 more annotations...
  • Serverless can also mean applications where some amount of server-side logic is still written by the application developer but unlike traditional architectures is run in stateless compute containers that are event-triggered, ephemeral (may only last for one invocation), and fully managed by a 3rd party.
  • ‘Functions as a service
  • AWS Lambda is one of the most popular implementations of FaaS at present,
  • A good example is Auth0 - they started initially with BaaS ‘Authentication as a Service’, but with Auth0 Webtask they are entering the FaaS space.
  • a typical ecommerce app
  • a backend data-processing service
  • with zero administration.
  • FaaS offerings do not require coding to a specific framework or library.
  • Horizontal scaling is completely automatic, elastic, and managed by the provider
  • Functions in FaaS are triggered by event types defined by the provider.
  • a FaaS-supported message broker
  • from a deployment-unit point of view FaaS functions are stateless.
  • allowed the client direct access to a subset of our database
  • deleted the authentication logic in the original application and have replaced it with a third party BaaS service
  • The client is in fact well on its way to becoming a Single Page Application.
  • implement a FaaS function that responds to http requests via an API Gateway
  • port the search code from the Pet Store server to the Pet Store Search function
  • replaced a long lived consumer application with a FaaS function that runs within the event driven context
  • server applications - is a key difference when comparing with other modern architectural trends like containers and PaaS
  • the only code that needs to change when moving to FaaS is the ‘main method / startup’ code, in that it is deleted, and likely the specific code that is the top-level message handler (the ‘message listener interface’ implementation), but this might only be a change in method signature
  • With FaaS you need to write the function ahead of time to assume parallelism
  • Most providers also allow functions to be triggered as a response to inbound http requests, typically in some kind of API gateway
  • you should assume that for any given invocation of a function none of the in-process or host state that you create will be available to any subsequent invocation.
  • FaaS functions are either naturally stateless
  • store state across requests or for further input to handle a request.
  • certain classes of long lived task are not suited to FaaS functions without re-architecture
  • if you were writing a low-latency trading application you probably wouldn’t want to use FaaS systems at this time
  • An API Gateway is an HTTP server where routes / endpoints are defined in configuration and each route is associated with a FaaS function.
  • API Gateway will allow mapping from http request parameters to inputs arguments for the FaaS function
  • API Gateways may also perform authentication, input validation, response code mapping, etc.
  • the Serverless Framework makes working with API Gateway + Lambda significantly easier than using the first principles provided by AWS.
  • Apex - a project to ‘Build, deploy, and manage AWS Lambda functions with ease.'
  • 'Serverless' to mean the union of a couple of other ideas - 'Backend as a Service' and 'Functions as a Service'.

  • Active Resource is built on a standard JSON or XML format for requesting and submitting resources over HTTP
  • When a request is made to a remote resource, a REST JSON request is generated, transmitted, and the result received and serialized into a usable Ruby object.
  • ...2 more annotations...
  • REST uses HTTP, but unlike “typical” web applications, it makes use of all the verbs available in the HTTP specification
  • Relationships between resources can be declared using the standard association syntax that should be familiar to anyone who uses activerecord

  • in AngularJS, we have a separate model layer that we can manage in any way we want, completely independently from the view.
  • keep your concerns separate
  • do DOM manipulation and augment your view with directives
  • ...34 more annotations...
  • DI means that you can declare components very freely and then from any other component, just ask for an instance of it and it will be granted
  • do test-driven development iteratively in AngularJS!
  • only do DOM manipulation in a directive
  • with ngClass we can dynamically update the class;
  • ngBind allows two-way data binding;
  • ngShow and ngHide programmatically show or hide an element;
  • The less DOM manipulation, the easier directives are to test, the easier they are to style, the easier they are to change in the future, and the more re-usable and distributable they are.
  • still wrong.
  • Before doing DOM manipulation anywhere in your application, ask yourself if you really need to.
  • a few things wrong with this
  • jQuery was never necessary
  • use angular.element and our component will still work when dropped into a project that doesn't have jQuery.
  • just use angular.element
  • the element that is passed to the link function would already be a jQuery element!
  • directives aren't just collections of jQuery-like functions
  • Directives are actually extensions of HTML
  • If HTML doesn't do something you need it to do, you write a directive to do it for you, and then use it just as if it was part of HTML.
  • think how the team would accomplish it to fit right in with ngClick, ngClass, et al.
  • Don't even use jQuery. Don't even include it.
  • ry to think about how to do it within the confines the AngularJS.
  • In jQuery, selectors are used to find DOM elements and then bind/register event handlers to them.
  • Views are (declarative) HTML that contain AngularJS directives
  • Directives set up the event handlers behind the scenes for us and give us dynamic databinding.
  • Views are tied to models (via scopes). Views are a projection of the model
  • In AngularJS, think about models, rather than jQuery-selected DOM elements that hold your data.
  • AngularJS uses controllers and directives (each of which can have their own controller, and/or compile and linking functions) to remove behavior from the view/structure (HTML). Angular also has services and filters to help separate/organize your application.
  • Think about your models
  • Think about how you want to present your models -- your views.
  • using the necessary directives to get dynamic databinding.
  • Attach a controller to each view (using ng-view and routing, or ng-controller)
  • Make controllers as thin as possible.
  • You can do a lot with jQuery without knowing about how JavaScript prototypal inheritance works.
  • jQuery is a library
  • AngularJS is a beautiful client-side framework

ruby environment development shell

shared by 張 旭 on 12 Jun 15 - No Cached
  • If you want to be able to effectively manage web apps in development and in production, you have to understand environment variables.
  • Every program you run on your server has at least one process. That process gets its own set of environment variables.
  • Once it has them, nothing outside of that process can change them.
  • ...9 more annotations...
  • Every program you run on your server gets its own set of environment variables at the moment you launch it.
  • Environment variables die with their process
  • Every process has a parent. That’s because every program has to be started by some other program.
  • Child processes inherit env vars from their parent
  • By default a child will get copies of every environment variable that its parent has. But the parent has control over this.
  • Changes to the environment don’t sync between running processes
  • shells do provide their own “local” shell variable systems
  • Environment variables are NOT the same as shell variables
  • use the export command to convert the local variable into an environment variable.
