Why build your forms with Redux Form – DailyJS – Medium

  • Why build your forms with Redux FormWhen I usually create forms for my React/Redux applications I tend to keep the value of the inputs on the application state, with little to no editing, (because my forms are usually simple), I never stopped to realize what that means.
  • It also receives an event handler that will update the state when the user interacts with it.It means that when the user types the letter “J” on the input, what is visible is not the same “J”, it may be an identical “J” that comes from the state, or whatever…
  • It keeps track of all common application form state such as:The fields that are in the form;The values of each field;The focused field;If the field values are valid;The fields that the user have interacted with;If the form is being submitted;If is happening any asynchronous validation.Let’s take a look at a…
  • It will also hand us the handleSubmit function, which will take care of the submission behavior.The Field component takes our input component as its props and acts as a container, bringing the application state to the input component and binding the event handlers to update the state in store.Look at…
  • Look that the default value of the input is defined when the high-order component reduxForm is called and comes to the input within the prop input and not from the react’s prop defaultValue, this way we guarantee that our form values are all represented in the application state.In summary, having…

Step by step guide for writing awesome React components

  • Now imagine the most verbose way to write it.class SlothImage extends React.Component { render() { return img src=’sloth.gif’ alt=’Pretty face’ }}export default SlothImageThis code is completely correct and performant but can it be shorter?
  • This component has no use of lifecycle methods.const SlothImage = props = { return img src=’sloth.gif’ alt=’Pretty face’}export default SlothImageTwo lines have been spared by converting the class component to the functional component.
  • /*The props should now be built like this:{ src: ‘sloth.gif’, alt: ‘Pretty face’,}*/export default props = img {…props}The dots are called a spread operator (❧).
  • My personal taste for writing more complex components is as follows:export default ({ separateNext: underline, rightComponent, onRightComponentClick, …rest: imgProps}) = { return ( Row underline SlothImage {…imgProps} / /Row )}If I could pick one rule in writing React components it would be exceeding the 80 characters mark (❧) in a…
  • The sign of overcomplication is the usage of “enum” like props or having too many props.TextInput required width=’col-6′ height=’xlarge’ bgColor=’#a4a4a4′ type=’primary’ suffix=’dollar’ 1337/TextInputEvery component should have a single responsibility (❧) and a reasonable amount of flexibility.

Going through the process of learning and using React and Redux I came to a following conclusion – they are not hard to grasp but are fairly difficult to master. Both are pretty minimal when it comes…

Using Bootstrap With create-react-app

  • From your project folder, enter the following: – – Now the Bootstrap files will be located in your folder.
  • This is where we will put our bootstrap source files.
  • You will need to have the installed globally, so from your command line enter: – – You will also need grunt and other libraries install locally into your project, so enter the following from your project folder – – In order to import your bootstrap files, you need to create…
  • From our command line inside of our project folder we can now enter to compile our LESS files one time, or we can enter to watch the source files and compile on any changes.
  • Once you have built your application using Bootstrap, you can at the end go through and edit the source files so that 1) you only import the Bootstrap components which you are using and 2) make sure all the components look exactly the way you want them to.

These days, starting a web application is very easy. Using create-react-app along with Bootstrap will give you everything you need.

Mike Grabowski: Compared to its alternatives, React is what makes React Native shine

.@grabbou: Compared to its alternatives, #ReactJS is what makes React Native shine

  • We have special weekly meetings of every open source project team which makes it easy to join any time.
  • We plan to make it public at some point, so that it’s not only transparent for folks what we are up to, but also easy to join and help us deliver for better tomorrow.Does the focus on modern technology stack help Callstack acquire more clients?It is just one of the…
  • What they are looking for is to solve specific problems that they have, and right now, the best answer to this problem is: Use React Native.What’s the best use case for choosing React Native over fully native applications?If you have an app that’s already written in React and looking into…
  • There are hundreds of other, perfectly legitimate use cases, to go with React Native.Have you experienced React license issues bothering your clients?No.What do you think is the future web and mobile development?That really depends on vendors.
  • I am paying attention to the way Kotlin evolves on other platforms as well as Flutter, that unlike React Native, uses its own rendering engine and compiles ahead of time.Are you excited about speaking at React Day Berlin?Yeah, totally!

Because Mike is going to speak about animation in React Native at React Day Berlin on December 2, we asked him a couple of questions about his experience with the technology and his current position…

Realtime GraphQL UI Updates in React with Apollo. ― Scotch

Realtime GraphQL UI updates in React with Apollo  #ReactJS #GraphQL

  • // ChannelsListWithData = graphql(channelsListQuery, { options: { pollInterval: 5000 a new channel from another client now updates our list of channels after 5 seconds, not the best way of doing it but a step in making the application realtime.
  • store.writeQuery({ query: channelsListQuery, data }); – } – }) – … – As soon as the mutation completes, we read the current result for the channelsListQuery out of the store, append the new channel to it, and tell Apollo Client to write it back to the store.
  • To add WebSocket support to our existing interface, we will construct a GraphQL Subscription client and merge it with our existing network interface to create a new interface that performs normal GraphQL queries over HTTP and subscription queries over WebSockets.
  • … – We edit the following part to disable const ChannelsListWithData = graphql(channelsListQuery, { options: { pollInterval: 5000 }})(ChannelsList); – … – Edit the above to: const ChannelsListWithData = to add a new channel now in our app does not reflect the changes until we refresh the page and that…
  • jsx – … – import { SubscriptionClient, addGraphQLSubscriptions } from networkInterface = createNetworkInterface({ – uri: wsClient = new { – reconnect: true – }); – – // Extend the network interface with the WebSocket – const = addGraphQLSubscriptions( – networkInterface, – wsClient – ); – To enable subscriptions throughout our…

This is the fourth and final part of a 4-part series of articles explaining the implementation of GraphQL on an Express Server and similarly in a React client using Apollo. In this article we look at how to maintain realtime UI updates after implementing different GraphQL updates that result in either creation, update or deletion of data on the server side. For part 1, 2 and 3, refer to the links:
