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.

Exploring the React Context API with Provider and Consumer

  • It explains how to use React’s new context API for passing props down the component tree.
  • Basically, React’s context API takes the clutter away of passing mandatory props, that are needed by every component, down your whole component tree.
  • Therefore you could use React’s context API to give every component access to the colored theme.
  • As you can imagine, following this way every component that needs to be styled according to the colored theme could get the necessary information from React’s context API by using the Consumer component now.
  • This Provider component uses React’s context API to pass down the state implicitly.

React’s Context API is a powerful feature for passing props down the component tree without the need to tell components in between about them. React’s context creates a Provider and Consumer component that enable us to use this powerful feature …

Introduction to ReactJS


#javascript #reactjs #webdev #womenintech

  • ReactJS focuses only on the rendering of View (part of MVC), as it does not implement the entire MVC pattern, but tightly focuses on the development of components (views) which are displayed on the user-interface so that it is more efficient in developing dynamic and interactive user-interfaces and its components….
  • Traditionally, when we used to change the data (model in MVC) at server-side, we used to reload the entire page (at client-side) to implement or reflect the updates from the server, which make processing very slow and creates bad user-experiences.
  • But ReactJS has solved these issues as it works at the client-side and takes care of the updates from the server by just changing those particular components or parts of interfaces which are changed, and it does not reload the entire page.
  • DOM (Document Object Model) is the user-interface or HTML document which is rendered or displayed on the screen, and if we have to rerender the entire DOM every time to reflect the changes that come from the server, it would be very expensive and take many CPU-cycles and processor time….
  • To overcome these issues, ReactJS creates Virtual DOMs in memory and whenever any data is changed at the server, ReactJS rewrites the Virtual DOM, and then it performs “diff” operations between all Virtual DOMs… one which was created initially and the other which is created after the change of data….

ReactJS is a JavaScript library used to develop dynamic user-interfaces or the components of user-interfaces like search bars, sliders, and widgets in web applications. ReactJS focuses only on the…

Evolving Patterns in React

  • A good way of bypassing this is to use props destructuring together with JSX spread , as you can see here: – – So now, you can change the props needed for and be sure that those props are not referenced in multiple components.
  • If you are using Redux, you will recognize that the function is a HOC — takes your component and adds a bunch of props to it.
  • Let’s implement a basic HOC that can add props to existing components.
  • Each HOC will introduce an additional React Component in your DOM/vDOM structure.
  • Render props can be used in situations where you need some reusable logic inside the component and you don’t want to wrap your component in a HOC.

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.

React Native Paper: Material Design for React Native –

  • Open a Terminal in your project’s folder and run, – – After installation, you’ll need to link your root component in from .
  • It’s a good idea to wrap the component which is passed to .
  • The component provides the theme to all the components in the framework.
  • It also acts as a portal to components which need to be rendered at the top level.
  • You can provide a custom theme to customize the colors, fonts etc. with the component.
