  • You can apply CSS to your Pen from any stylesheet on the web.
  • Just put a URL to it here and we’ll apply it, in the order you have them, before the CSS in the Pen itself.
  • If the stylesheet you link to has the file extension of a preprocessor, we’ll attempt to process it before applying.
  • You can also link to another Pen here, and we’ll pull the CSS from that Pen and include it.
  • If it’s using a matching preprocessor, we’ll combine the code before preprocessing, so you can use the linked Pen as a true dependency.

How I test redux-saga – codeburst

  • How I test redux-sagaI’m a fan of redux saga (although I’ve been keeping an eye on redux-observable too).
  • I particularly like having all async logic in one place, making it easily testable and having powerful async control flows available where necessary.Because the saga effects only construct a special object that is consumed and executed by the middleware (aka they dont do much!)
  • , it is really easy to test your sagas with no mocking required.Few points of note:The mock result of the api (true or false) is injected into the subsequent next() call after the api call.
  • clone()” to test different control flow branches

GraphQL Authentication with React Native & Apollo [Part 2/2]

GraphQL authentication with React Native & Apollo  #GraphQL #ReactNative #Apollo

  • We’ll use gql to write our graphql query and the graphql higher order component to tap into the Apollo client.We know that our mutation looks something like this (from working with it directly in Launchpad in part 1).
  • Now we need to to be able to pass variables from our user to the mutation.Finally, we want to make this mutation available to the Register component via this.props so that the component agnostic from the Apollo bindings.Now to use it we’ll go to the end of our handleSubmit function…
  • Click “Log Out”, refresh the app, and you’ll see it no longer brings you to profile.Login with Email and PasswordLogging in with email and password is just like sign up, we’re just calling a different mutation.
  • I’ll let the code do the talking.Now to call the login function available on this.props, save the JWT and change screens (on success) or show an error.Showing User InformationThe final thing we’ll do, to demonstrate that things are actually working and it’s not just a big facade, is show the…
  • The server is expecting the JWT to be coming in the authorization header and uses that to find the current user.To pass this token along with the request we’ll use setContext from the apollo-link-context which is another apollo link we’ll use.

This is the second and final part of a series where I cover how to setup authentication with React Native, GraphQL, and MongoDB. Below is part 1 where we setup the server. In this part we’ll be…

ReactJs: Using stores to improve your code – Doyin Olarewaju – Medium

ReactJs: Using stores to improve your code  #reactjs #react #javascript #reactjs

  • ImagesOne of the first steps i take is to create an ImageStore.
  • This helps me keep all images in one place, helps ensure my images are compiled with react and also helps me not worry about relative links to my app root.So some code://say the name of this file is ImageStore located at stores/ImageStoreimport UserImage from FriendImage from default { UserImage, FriendImage}Then to import it in your viewsimport ImageStore from ‘.
  • /stores/ImageStore// excluded some imports for brevity sake………export default class TestClass extends Component {render() img src={ImageStore.UserImage} alt=’User’ / … … }}Thats it.
  • Just add all images you wish to use in your app into the store and import the ImageStore.
  • No relative links required, the image gets compiled into your app and best of all, if the image location needs to change for any reason all you need to do is change in the ImageStore file and it changes everywhere.

I’m a sucker for well written code. When code is badly written, the app kinda gets boring and it becomes a task to work on the codebase. I love stores in js, especially since es6. Simple classes with…

Testing with Mocha – Kevin Wang – Medium

Testing with Mocha  #tdd #react #mocha #javascript #reactjs

  • js file and running “npm test” in the console.var assert = function() { describe(‘#indexOf()’, function() { it(‘should return -1 when the value is not present’, function() { assert.equal(-1, [1,2,3].
  • indexOf(4)); }); });});The test should pass and you should see the below.From the example above though, the function that the test is testing for is written in the same file.
  • toFixed(2) }, sleepApneaIncrease: function(amount){ return (amount * 1.06).
  • toFixed(2) }, heartDiseaseIncrease: function(amount){ return (amount * 1.17).
  • toFixed(2) }, checkCondition: function(amount, condition){ switch (condition) { case “Allergies”: return case “Sleep Apnea”: return case “Heart Disease”: return default: return 0; } }}I store them all in an object so thatI am able to export out and require them when I need to.

My first experience with Mocha is at Flatiron. When we were doing Javascript labs/work we used Mocha to test out the code that we wrote, it made sure that the results are as we expected. This was my…
