Easily Build Forms in React Native – React Native Development – Medium

How to Easily Build Forms in React Native:

  • It makes creating forms in React Native easy by simply having to define a model for that form and you’re set!
  • Snack will automatically pull that in for us.Tip: I find that scanning the QR code from the Expo app on my device gives the best development experience.If you prefer to do this outside of Snack make sure you install tcomb-form-native via npm or yarn.What We’re BuildingWe’ll be building a sign up…
  • First we need to get the Form component (line 6) then we need to render the form and pass our model to it as the type (line 19).
  • We create an object, add a key named “fields” (since we’re modifying the fields), add a key to this object that aligns with the key in our model (“terms”), and then inside that object we set the new label.Code is easier to understand.Then pass those options to the Form componentLet’s…
  • Just about everything in the default form is customizable.As you can see tcomb-form-native makes building forms quick and easy but also gives you the flexibility you need to create forms the give users the necessary info and fit with the rest of your app (unless I’m designing of course).

If you’re building a React Native app it’s almost a guarantee that you’ll have to build at least one form. The reality is you’ll probably build quite a few (sign in, sign up, edit profile, etc.) Yeah…

cans: A framework for building #ReactJS #MobX application:  #JavaScript

  • cans: A framework for building React MobX applicationI’ve used MobX for a long time.
  • Every UI component can write as a function of state ((state) = UI), which let you test the UI more easy, just pass different state and expect the return value.Using MobX and React means you get all of it.
  • And then my framework cans came out.What is canscans is a framework for building React MobX application.
  • Note that you can also pass a high order function that return a observable.app.model({ namespace: ‘counter’, observable: app = observable({ /** … **/ })})In this case, you are able to access the app instance, in order to access other models or plugins.viewThe way to react the React component is using mobx-react.
  • The different part is it will be bind in app.plugins, and return not only observable in observable key:ConclusionThe main idea of cans is always to organize your stores.

I’ve used MobX for a long time. It is awesome when I just want a simple state manager for my React application. I always think about how to organize my React MobX application. Because MobX is too…

React is cool, deal with it – Medium

#React is cool, deal with it  #reactjs

  • We’re talking about three different files to fetch and display in a table in contrast to simply develop a “PropertyList” component and all related logic there.
  • If you were developing following MVC pattern you would first implement a Model which would represent the property and implement any related activity of API communication in that layer, add a route to a controller which would fetch the model and pass it to the view.
  • React is hard to learn, we’re all used to seeing javascript and html in different files, we’re all used to MVC and it lacks much functionality so you need to add some different things to handle routing, api calls, jsx support, etc..
  • Everybody knows how crazy javascript world has been lately releasing new tools faster than you can learn them, there’s one tool, React that markets itself as the V in MVC ( or at least it used to ) that slowly started to take over front-end development still i read about many people complaining with wrong arguments about why they don’t like it so i decided to talk about what is it that is so great about react.
  • With react you don’t write HTML, they implemented JSX which is a processor that lets you add xml style tags in javascript so instead of having a separate file for your scripts you write both the logic and the content in a single file.
