Styling React for Reuse

  • We’ve all excitedly installed a third-party component that beautifully fit our functional needs, only to sacrifice design, and waste hours covering our code in !
  • Between state-based components, class naming conventions, and the inline versus stylesheet wars, it’s difficult to wrap your head around your own components, let alone releasing them for reuse.
  • In this session, we’ll take all that information and distill it into an easy to digest discussion for those who are looking to standardize their own components, or release their first components for public use.
  • My goal is to help the community, at large, think about CSS in their OSS components in an extensible way.

In this session, we’ll take all that information and distill it into an easy to digest discussion for those who are looking to standardize their own components, or release their first components for public use.

Setting up a React project from scratch – codeburst

  • In your terminal type these command.In the above snippet firstly we are creating a directory named reactProject and then inside it, we are running the command npm init to start a new node project.You will be prompted to input information about your project.
  • if you wish to add information about your project go ahead.Now our node project is up and running.Our next step will be installing react react-domWe are going to use webpack for bundling our code into one js file.
  • As you already know we have to configure the webpack to make use of our babel loader to transpile and output our bundle.js file.in your project root dir create a folder named webpackWe created a folder named webpack and inside it created an empty file webpack.dev.config.js.in your webpack.dev.config.js import webpack…
  • Inside your project root dir create an index.html file.In our index.html we have a mount point div id=”app”/div and we also added the source to our bundle.js file.Next step will be building our index.js file which will be the entry point for our webpack configuration.
  • Inside your app directory create a folder named containers and inside that App.jsOpen your App.js file inside it add this code.We create a simple component which will display This is my new react app when rendered.let’s check our app in the browser to see if it works or not.but before…

Setting up a React project from scratch can be a daunting task for beginners. Lots of npm modules to install, lots of configuration and other tasks. There are lots of react project seeds we can use…

I wish I knew these before diving into React – OpsGenie Engineering

  • By default, setState triggers a re-renderThe default behavior of React is to re-render on every state change, and most of the time it is okay to rely on this.
  • However, re-rendering unnecessarily wastes cycles which is not a good practice.Each component has a method called shouldComponentUpdate and it is called everytime you change state or pass new props from the parent component.
  • We can simply divide lifecycle into three parts:Mounting: an instance of the component is being created and inserted into the DOM.Updating: component is being re-rendered, can be caused by changes of props or state.Unmounting: component is being removed from the DOM.It is very important to understand how these methods work….
  • Compare this.props with nextProps and if there is a significant change, act on it.Two important notes here:React may call componentWillReceiveProps even if the props have not changed, so comparing this.props and nextProps is is invoked before a mounted component receives new props, this means React doesn’t call componentWillReceiveProps with initial…
  • Use React Developer ToolsReact Developer Tools lets you inspect the React component hierarchy, components’ props and state.

At OpsGenie, we had a deep dive into React for our Badges project. I learned many new things & made many mistakes. These are the things that really helped me.

Maximizing Debuggability with Redux – LogRocket

Maximizing Debuggability with Redux  #javascript #react #logging #debugging #redux #reactjs

  • By using front end logging tools like LogRocket, developers can easily understand and fix tricky bugs in production by reviewing the actions and state changes leading up to a bug.While this information is immediately useful in any Redux app, there is a lot more we can achieve by architecting an app with logging in mind.
  • When debugging issues, we can dig into this state object to see information on in-flight requests, queryCount (if we’re polling on a query), and timings.Storing this information in Redux is critical, since it puts full context on all network activity in the Redux logs.Rolling your own data fetching “framework”If you’d prefer a simpler approach, you can roll your own data fetching “framework” by simply dispatching explicit actions when querying and receiving data from the network.For example, lets say we’re building a blogging app.
  • This would then update state appropriately to:postsQuery: { url: ‘api.blog.com/posts’, isPending: true, data: […],}This example is far from thorough, but the idea is that by being explicit with Redux actions for each part of the request lifecycle, it becomes easy to debug any potential race condition or network error.Handling other sources of non-determinismIn addition to network fetching, there are lots of other sources of non-determinism that can cause bugs.
  • For example:myWebSocket.onmessage = function (event) { store.dispatch({ type: ‘BLOG_POST_UPDATE_RECEIVED’, payload: event, } store.dispatch({ type: ‘BLOG_POST_UPDATE_RECEIVED’, payload: event, }That way, when looking at the Redux logs for an error or user-reported issue, we can see all the data that was received over the websocket and, crucially, relate it in time to other redux actions and network requests.Local StorageOften, an app needs to read from local storage when it first starts up.
  • Once you get the library set up, you’ll see a new key in your Redux store called routing with information on the current router state.In addition, react-router-redux dispatches actions like @@router/LOCATION_CHANGE when its state changes.Also of note is that using react-router-redux lets you rewind router state when time-traveling in redux-devtools, since its state its state is derived from the state in Redux.A note about local vs Redux stateI don’t want to get into the debate on local vs Redux state here, but production Redux logging does change the calculus of this decision in some cases.

In my last blog post, Redux Logging in Production, I discussed one of the most important benefits of using Redux — debuggability. By using front end logging tools like LogRocket, developers can…

The Easiest Way to Learn React Native – Handlebar Labs – Medium

“The Easiest Way to Learn React Native” by @spencer_carli #javascript #react #reactnative

  • The Easiest Way to Learn React NativeI’ve spent a lot of time working with React Native.
  • I started using it very shortly after it was open sourced and have used it daily since that time — growing with the platform, experiencing different upgrading pains, transitioning between different navigators, and so on…I’ve also spent a lot of time putting together tutorials about React Native (40+ blog posts, 15+ videos) and talking to people getting started with it (hundreds of incredible emails).
  • There are a ton of great learning resources out there already but they can be scattered between dozens of blog posts, in a less than ideal format (some people like text, some like video, etc.), and some people just aren’t ready to invest hours upon hours researching yet.With all of this information I wanted to try my hand at putting together the easiest way to start learning React Native.
  • A time friendly, budget friendly, single source of information to get you that essential 20% of knowledge.That’s what Create Your First React Native App is.
  • Or think of it this way, if you value your time at $30 per hour and it saves you even an hour of your time, the course will have paid for itself.I’m excited to share this with you and I hope that it will make using React Native more accessible to more people!Sign Up for Create Your First React Native AppQuestions?

  • But right now I can not afford to work on my spare time as much as the project currently requires it.
  • I have been a part of this project since its early prototype days, and was able to spend quite some time working on it, including joining 3 code sprints fully focusing on it.
  • The time I have to offer is not much, about 20-30 hours per month, but it could allow me to concentrate on the boring parts of the rewrite such as polishing the visual looks of the components as well as those details that are a bit hard to provide in spare time.
  • So I’m looking for sponsors that would allow me to relocate some of my freelancing time towards finishing the UI rewrite .
  • The project will have immediate benefits like improved performance, correctly working media-queries and higher robustness of the UI due to the use of iframe for site content.

Neos CMS team is currently in the middle of UI rewrite on top of React. This project will have immediate benefits like improved performance, correctly working media-queries and higher robustness of the UI due to the use of iframe for site content. But main aim for it is to support ambitious plans of our project (such as structured editing of content) that would require a modern foundation.
