Redux Devtools for Dummies  #react #development #testing #redux #javascript #reactjs

  • In my opinion, this is the most robust and easiest to set up.npm install –save redux-devtools-extensionimport { composeWithDevTools } from ‘redux-devtools-extension’; into the store file.Finally compose your store with the imported module:import { composeWithDevTools } from store = createStore(reducer, composeWithDevTools( // other store enhancers if any));I recommend using this option over the others because it helps avoid issues with isomorphic applications.
  • Check out the additional features you can add and remove to the console hereHere is how one would add in those customized features:import { composeWithDevTools } from composeEnhancers = composeWithDevTools({ // Specify custom devTools options});const store = createStore(reducer, /* preloadedState, */ composeEnhancers( // other store enhancers if any));Also, if you do not have enhancers/middleware in your application, there is a more straight forward approach:import { devToolsEnhancer } from store = createStore(reducer, /* preloadedState, */ devToolsEnhancer( // Specify custom devTools options));Notice that we are using devToolsEnhancer here rather than composerWithDevTools.
  • If you installed everything correctly in your store initialization, it will show you something like this:If there is an error in your set-up, including exceptions thrown from your code, you will see this:Let’s break down whats happening in each section of the dev tools.Left-Side Console ToolsThe left hand column of the dash is showing in real time the actions that are firing on the current page (as defined by the action creator types).
  • The skip will cross out the action and show you your app without that action.Right-Side Console ToolsThe four tabs at the top right are in my opinion the most helpful of the tools.DiffThe right side of the console has multiple options to see the state of the application and the relation of each action to the state.When an action is selected in the left hand side of the console, the Diff option will show only what that individual action changed in the state tree.ActionClicking on the Action tab will show the individual action type and any data it is carrying along to the reducers.In the example above, this action has a type features/FETCH_SUCCESS and also carries data, the requested features to the reducer.
  • Including all of the combined reducers and their corresponding data branches.The Raw tab shows the action creator in a code view.StateThe state tab shows the entire state tree at the time of the action selected in the left hand side of the console.TestBack to the upper tabs, there is a test option.

Do you take one look at the docs and just give up? Did you know that you can completely control the currently running application’s actions/state through these tools? The first step is the easiest to…

ReactJS Authentication Tutorial, Part 2

ReactJS Authentication Tutorial, Part 2  #web_dev #front_end #cli #reactjs #Programming

  • The component is pulling data from an API, so it needs a way of holding that data.
  • In the constructor, we define the initial state as seen in the code below:

    In the method, we call the method we exported from the helper file and set state as seen below:

    Now, we took advantage of one of the ReactJS lifecycle hooks, .

  • So, we invoked the method in the hook as seen below:

    All we are trying to do is tell ReactJS to load the data from the API immediately when the component gets rendered.

  • Finally, we rendered the component with the ReactJS method.
  • This renders the root component in the div, which is the starting point of our ReactJS application.

We continue our series on creating an authenticated ReactJS application by looking at how to setup our front-end with the help of Facebook’s CLI tool.

Waterkant 2017: Modern WebDevelopment with ReactJS

Join @kaoDev to lear @reactjs at #waterkant17 #pureskills

  • Build your own chat app with modern JavaScript in your browser.
  • The focus is on ReactJS, a JavaScript library

    by facebook to render user interfaces in the browser.

  • To allow an easy start you can use a cloud workplace with a completely

    set up development environment.

  • If you have experiences with git and

    NodeJS you can checkout the project from GitHub and work locally, too.

  • Next to your Notebook you should bring a little bit of general software development experience, but no experience with react is needed.

  • A command line tool to help you extract react-toolbox style modules to static files so you can integrate it in nearly any stack.
  • It will help you extracting the CSS modules into static files you can import in your application, making react-toolbox very easy to adopt.
  • As is a command line utility, you can use it from the command line passing options inline like:

    But we really encourage you to use either or a custom configuration file so it’s more clear to visualize your configuration.

  • All of these options have the same name if you use them in your , a custom file or directly through the command line.
  • Some of them are aliased to be used from the command line but passing configuration variables is only allowed from a package of custom json file configuration.
