  • Typed actions are implemented using action type enum and corresponding action classes with type property and optional typed payloadTyped stateIt is very useful to define a type of the state object which is managed by the reducer.
  • Typing return value of our reducer is in fact the main ingredient for enabling great Typescript support discussed in this article – Example of a todos.reducer.ts file with all necessary type declarations for proper type-checking and code-completion supportCreating new state using Object.assign()To make our reducer useful we have to provide…
  • Returning of a new object has additional benefit of making implementation immutable which helps with the performance of our app, especially with change detection.Lets focus on the FILTER action which updates a value of the filter property in our state.
  • After all, were using Typescript and we are interested in the benefits it has to offer – Objects with additional properties which are not specified in the type of the reducer state will unfortunately NOT produce type errorsWe can make this work by using Typescript generics and specifying a type…

  • Wilberg claims that Google implemented clear and irrefutable policies meant to exclude white and Asian men in an attempt to increase the companys overall diversity.
  • Wilbergs lawsuit targets Google and 25 unnamed Google employees who allegedly enforced discriminatory hiring rules, quoting a number of emails and other documents.
  • Google allegedly purged non-diverse employee applications – – Wilberg alleges that several employees complained to Google about the companys hiring policies, but were either ignored, transferred, or demoted.
  • But two former Google employees sued the company early this year for allegedly discriminating against white men, in a far more nebulous and wide-ranging complaint.
  • Conversely, Google is also facing lawsuits alleging that it underpaid women, fired an employee for pro-diversity web posts, and created a bro culture that encouraged sexual harassment.

  • For those who still dont have a preference, in this article we show how to make a simple Hello World app with some of the existing alternatives: Vanilla JavaScript, AngularJS, Angular 2+, React, Vue.js and Knockout.js.
  • Vanilla JavaScriptSince Onsen UI components behave like native DOM elements (Custom Elements) its really simple to deal with them with pure JavaScript or jQuery.
  • Onsen UI Hello WorldVanilla JavaScriptIn Onsen UI, the right place to initialize a page is in its init event.
  • Onsen UI Hello WorldReactMore examples with React Components for Onsen UI here.
  • Some of them are complex frameworks that need a lot of bootstrap code but become very handy when the app gets bigger and need a robust way of organizing data and views.

  • Types of AngularmodulesThere are 3 main types of NgModules you can do: – modules of pages;modules of global services;modules of reusable UI components.Youll at least do modules of pages (otherwise your app is just empty).
  • These modules contain 3 things: – /shared: services and interfaces,/pages: routed components,/components: pure presentation components.Shared services forpagesTo display a page, you need data first.
  • ReusabilityModules of global services are reusable through different projects if you take care to have no specific dependency in them (no UI or app specific code), and if you separate each features in different modules (do not put every service in just one big global module).
  • SummaryExample of a module of global services: – Modules of reusable componentsModules of reusable components are modules of UI components you would like to reuse in different projects.
  • SummaryExample of a module of reusable UI components: – ConclusionIf you follow those steps: – youll have a consistent architecture: in small or big apps, with or without lazy-loading,your modules of global services and your modules of reusable components are ready to be packaged as libraries, reusable in other projects,youll…
