  • Jenkins can speed up repetitive tasks that robots are much better performing and Docker simplifies spinning up VM’s for your application in a very simple and repeatable way.
  • What I’m going to cover here is how to setup your Jenkins server in a Docker container and how to fix some of the limits of the Jenkins official image.
  • While it is nice of Jenkins to offer an official docker image, you’ll quickly run into a few issues if you are doing anything even slightly other than compiling plain Java.
  • For instance, Maven, the popular dependency management tool for Java, is not included in the Docker container.
  • You’ve learned to create a Jenkins Docker-container that’s ready to run jobs for Java, Ruby and NodeJS projects.

Deploy a Restaurant Menu App in 3 Steps – Hacker Noon

  • This restaurant menu app was built using Nuxt, Vue.js and Vuex with content powered by Cosmic JS.
  • Cosmic JS is an API-first Content Management Platform that allows developers to build apps in any programming language while giving content editors a familiar content editor to manage dynamic content from the cloud.
  • Install the Restaurant Menu App – Cosmic JS gives you the ability to filter between programming languages such as Node.js, Vue.js, React, AngularJS and more.
  • Confirm Deploy Location and Branch – Deploy Branch Confirmation ModalNow that your app is deployed to the Cosmic JS App Server, you’re free to completely manage your Restaurant Menu App and all of its content from one place.
  • Carson Gibbons is the Co-Founder CMO of Cosmic JS, an API-first Cloud-based Content Management Platform that decouples content from code, allowing devs to build slick apps and websites in any programming language they want.

In this blog I will demonstrate deploying a Restaurant Menu App in 3 steps. This restaurant menu app was built using Nuxt, Vue.js and Vuex with content powered by Cosmic JS. It connects to the Cosmic…

Redux vs MobX: Which Is Best for Your Project?

Redux vs MobX: Which Is Best for Your Project?

☞ 

#Reactjs #javascript

  • I’ve migrated this CRUD Redux project to MobX to use as an example in this article.
  • The code for the projects mentioned in this article can be found on GitHub: – – If you enjoy this post, you might also like to sign up for SitePoint Premium and watch our course on working with forms using React and Redux.
  • If you prefer writing object-oriented code, you’ll be pleased to know you can use OOP to implement state management logic with MobX.
  • Believe it or not, the logic defined in both versions do the same tasks, which are: – – In Redux, we’ve used 33 lines of code.
  • A major benefit of the MobX version is that you can reuse the base code in almost all the domain store classes with little or no modification.

For a lot of JavaScript developers, the biggest complaint with Redux is the amount of boilerplate code needed to implement features

How to Use New React Context Api detailed � – codeburst

  • How to Use New React Context Api Context Api is available in the react16.3 so let’s build a counter using Context api.
  • Context Api helps us to pass down the data to the components without use of props at every component.In our counter app we only pass down one level.So Let’s install a react app using create-react-app – npm install -g newContext – cd newContext – npm start //to start dev serverNow…
  • app.js(using props)Now we are replacing it with context API Instead of using props in the Counter component.
  • First, we need to import NumberContext from our context.js file – app.js(uses context api)In line 39 above code tells first we are providing value to our component by wrapping our Counter component with the NumberContext.Provider.
  • The completed app looks like below image – That’s all in react documentation says Context is designed to share data that can be considered “globalâ€� for a tree of React components.

Now we are replacing it with context API Instead of using props in the Counter component.
First, we need to import NumberContext from our context.js file In line 39 above code tells first we are…

How To Open Source Parts Of Your Private Project With Bit

  • Using Bit, you can isolate these sets of files (we call code components) from your project and share them with the open source community, while keeping their source project private and intact.
  • js – │ └── index.js – └── utils – └── noop.jsBefore Bit, we would have to create a new GitHub project for this component, remove hello-world from your private project and make all its dependancies (packages as well as other files from the project) available for the new project.
  • With Bit, you can keep this component as part of your private project and still make it available to the community to discover, use and collaborate on.
  • Open source parts of your project to the communityTo make sure your components are truly executable outside of the project’s context, Bit will build an isolated component environment and apply all configured extensions to test, compile or perform any other defined task.
  • You can also use bit import to bring the component’s source code into other projects, develop them and merge changes between different projects.

How to make parts of your private projects open source and make their components available to the community without having to split your repositories or create new projects on GitHub. Learn more.

React Router 4: A Practical Introduction

React Router 4: A Practical Introduction  #reactjs

  • In previous versions of React Router such as v3, route protection code looks like this: – – The component had a prop that accepts a method that allows entry or refusal to a URL location based on a user’s authentication status.
  • In this example, the Auth Service will simply be an object like so: – – Now, let’s build the like so: – – The code above simply illustrates that if the authentication status of the user is true, then a component would be rendered else the user would be redirected…
  • is a higher order component from React Router that allows re-rendering of its component every time the route changes with the same props.
  • Add code to your like so: – – In the code above, we imported a new component, from React Router.
  • Now, all we need to do is map over the routes array as shown in the code below: – – In the code above, whenever the route’s path matches the URL location, the leftbar component will be rendered.

React Router 4 uses declarative approach to routing. In this tutorial, you’ll learn how to use React Router 4 in your web projects via practical examples.

React Tutorial: A Comprehensive Guide to learning React.js in 2018

  • These components are defined either in pure JavaScript or they can be defined in what the React team calls “JSX”.
  • The reason the React team went with this approach is because, since the virtual DOM is a JavaScript representation of the actual DOM, React can keep track of the difference between the current virtual DOM(computed after some data changes), with the previous virtual DOM (computed befores some data changes).
  • In more layman’s terms, because manipulating the actual DOM is slow, React is able to minimize manipulations to the actual DOM by keeping track of a virtual DOM and only updating the real DOM when necessary and with only the necessary changes.
  • The process looks something like this, – – Some user event which changes the state of your app → Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
  • Signal to notify our app some data has changed→ Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
