Testing a React project with Karma and Webpack

Test a #ReactJS project with Karma and Webpack:

  • The plugins section specifies that Karma should run the karma-webpack, karma-jasmine and karma-chrome-launcher plugins.
  • karma-chrome-launcher – opens up an instance of Chrome when we run the tests.
  • The command line interface for Karma needs to be installed globally.
  • javascript , karma , react , webpack
  • karma-jasmine – the Jasmine provider so that Karma can understand the results of our tests.

Presentational and Container Components — Medium

Presentational and container components: What's the difference? #ReactJS

  • Both presentational and container components can contain other presentational or container components just fine.
  • ** In an earlier version of this article I claimed that presentational components should only contain other presentational components.
  • When you notice that some components don’t use the props they receive but merely forward them down and you have to rewire all those intermediate components any time the children need more data, it’s a good time to introduce some container components.
  • Functional components are simpler to define but they lack certain features currently available only to class components.
  • Presentational components can be stateful, and containers can be stateless too.

React In-Depth: Component Evolution and Composition...  #reactjs #javascript #webdev

  • In other situations, Component intentions will change over the lifespan of the application.
  • Lets take a quick moment and discuss the process of application architecture.
  • As our applications scale, development time can be dramatically reduced through this process.
  • The other challenge with application architecture is trying to understand our needs.
  • Trying to find the right balance is the hardest part of application architecture.

Component reuse and composability are some of the core tenants of React development. As our applications scale, development time can be dramatically reduced through this process. Yet, creating reusable Components takes planning and understanding to support multiple use cases.

Why GraphQL is the future — Building Apollo — Medium

Why GraphQL is the future – and what it means for you:  #ReactJS

  • Where REST has only an ad-hoc approach, GraphQL has a clean layer of abstraction
  • Companies turn to GraphQL because they realize that REST can’t help them solve these problems, but GraphQL can.
  • Using Facebook means using GraphQL.
  • Their REST API has gotten so complicated that it’s a significant drag on product development.
  • Facebook has been using GraphQL since 2012 – well before it was open-sourced in July of last year.
