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…

Easily Build Forms in React NativeIf you’re building a React Native app it’s almost a guarantee that you’ll have to build at least one form.

A few things you might have to take care of…Creating the necessary components (text inputs, select inputs, checkboxes, switches, etc)Writing/finding validation logicUpdating your components to display any errors (I always forget to do this)Updating your UI whenever you change fieldsNone of these things are difficult, but they can be time consuming. Especially if you’re trying to ship something quickly.In the past I’ve always done all of this myself. But it takes time away from what I really want to be doing.I started looking around for solutions to solve this problem and came across tcomb-form-native. It makes creating forms in React Native easy by simply having to define a model for that form and you’re set! No fussing around with a dozen components.SetupTo get started I’ve put together a Snack that will allow us to do all of our work on the web. It’s an awesome tool.You’ll notice at the top of the file I’ve added import t from ‘tcomb-form-native’; which is the library we’ll be using to build our form. 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…
