Introducing form-for. #ReactJS Forms Made Easy

  • Binding componentsAs you can see on the code above, each field has a type set to it; some even have a couple extra properties.Now, we need to tell form-for what components to render.
  • I created a package for bootstrap components that makes your life veeery easy.
  • Building the formNow, let’s put together the User, the bootstrap components and the Form and Field tags.4.
  • The code is very straight forward, just like the one you saw above.And if you want more sandbox examples, I have two others in my profile: MobXFormFor goes really well with MobX.
  • If you don’t like comment too, lemme know how you think it could be

I’ve been coding for a few years and played with a few technologies. In this path, I’ve become a big fan of a Rails gem called simple_form. I’m also a fan of React. With these two in mind, I decided…

A React Navbar Component by Dan on CodePen

A simple, responsive #Navbar using #ReactJS:  #Coding

  • I’m going to give it a name of NavComponent because that just makes way too much sense, and inside the render function, toss in an empty (for now) set of tags to wrap around everything else that will go in there:

    And underneath all that I’m going to render the component inside the tags in my index.html:

    Ok, so we have a basic component that renders an empty nav.

  • This will give my a “hamburger” icon (courtesy of Font Awesome) for smaller screens that need a drop down menu.
  • Since our drop-down menu is contained in the “narrowLinks” className, we’re going to target that in our function:

    And then tell our function to toggle the drop-down based on its current CSS display value:

    And to make the new function work, we need to give our and tags inside “navNarrow” an onClick:

    That just about wraps it up.

  • I obviously don’t want to see both sets of links all the time, and since we’re using mobile-first design, we’re going to set our “navWide” links to hidden:

    And we’re also going to stick our hamburger icon and drop-down links on the left side of the screen, just for funsies:

    So by setting our icon to float: left, that’s taken care of.

  • And finally a media query to switch between our mobile drop-down menu and our larger screen mode with just a row of our links:

    For a working example, click here.

I use React a lot, and I use navbars a lot, so this was just an obvious one for me. This is nothing extravagant. I’m not using React Router in this example, just some tags. But it is responsive, so that’s fun.

The Creative Network Session 5 — GraphQL schema V1 – Fullstack Network – Medium

The Creative Network Session 5 — GraphQL schema V1  #react #graphql #reactjs

  • The Creative Network Session 5 — GraphQL schema V1Previous sessionsIntroduction sessionSetting up reduxHome Page with ReactSetting up GraphQLLast night we continued to work on the first version of our GraphQL schema.
  • Video here:We started setting up the tools of GraphQL such as Apollo in session 4.
  • This session our goal was to having a working schema enough to query data from our React component from Home Page, which looks like this:As you can see from the image, every Card looking object is suppose to be a single post, containing name, description, tags and other pieces of information.
  • We decided to name this a Topic in our schema, and we can query the GraphQL for all or single Topic object with its related data.Code is relative simple, and we ended up having a schema looking like thistype Topic { id: String title: String description: String thumbnail: String tags: [Tag]}type Tag { id: String name: String}type Query { allTopics: [Topic]}schema { query: Query}This would allow us to query our server side with queries such as this:{ allTopics { id title description thumbnail tags { id name } }}And result would look like thisNow that we have a working version of the GraphQL schema for the home page, we realize that it would be difficult to continue building the schema, because we are not sure what kind of content and data structure the client side would need.
  • So we decided now is a good time to go back to our React client.We are also planning to deploy the server side code to Heroku so everyone can play around, stay tuned!

React and third-party libraries

#ReactJS and third-party libraries:

  • It uses the Tags component that displays an unordered list based on the passed tags prop.
  • Component { render() { return (
      { this.props.tags.map((tag, i) =>

    • { tag }
    • ) }

    ); } }; // App.jsx class App extends React.

  • The very first thing that we have to do is to force a single-render of the Tags component.
  • class Tags extends React.
  • Every time when we click the button we update the state and trigger rerendering of Tags component.

React in patterns project. For other interesting patterns check out the repo.The example jQuery plugin for my example. It transforms an unordered list to input field for managing tags: plugin code. It works like that:. class. It uses the component that displays an unordered list based on the passed prop. When React renders the list on the screen we know that we have a tag so we can hook it to the jQuery plugin.Force a single-render component. That’s because when React adds the elements in the actual DOM we want to pass the control of them to jQuery. If we skip this both React and jQuery will work on same DOM elements without knowing for each other. To achieve a single-render we have to use the lifecycle method like so: here we are saying that our component will never rerender. If defined is used by React to understand whether to trigger or not. That’s ideal for our case because we want to place the markup on the page using React but we don’t want to rely on it after that.Initializing the pluginAPI for accessing actual DOM nodes. We have to use the attribute on a node and later reach that node via . is the proper lifecycle method for initializing the plugin. That’s because we get it called when React mounts the result of the method. lead to React rendering the with two items and then transforms it to a working tag editing widget.Controlling the plugin using React field. Such action will be triggered by the React component and needs to use the jQuery API. We have to find a way to communicate data to component but still keep the single-render approach. class and a button which if clicked will pass a string to component. component. However, because of we update nothing. The only one change is that we get a value of the prop which may be captured via another lifecycle method – : is a pure jQuery code. is a nice place for calling methods of the third-party library. component:Conclusion / blog of Krasimir Tsonev – front and back-end developer who writes for web technologies
