- Redux for Transactional Apps – – Building a consistent transactional app across multiple platforms can be tricky.
- Learn more about how Netflix is utilizing Redux and a robust backend service jointly, for our signup app.
- The app isolates the UI from state in order to maximizing reusability and scalability.
- 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…

- Did a little bit of coding.Monday: Since I was off for Labor Day, I decided to devote the day to really getting a lot done on my refactor project.
- I learned A LOT about what you can and can not do in React!
- Worked out the integration of using Google Sheets as a backend to update my info section.
- That turned out to be a lot more difficult than I thought, but I think it will be beneficial in the end.
- I also got the audio player working the way I want.Right now, all I have to do is add the content for the thank you and tech built with sections of the info page.

- Configure Fresco in React NativeRecently while carrying out some Android performance profiling on a new React Native feature at Hudl, I noticed some potential memory issues when loading and displaying a large amount of images.
- Under the hood the React Native Image/ component uses another Facebook library for Android called Fresco which caches images automatically (amongst other things).
- When I dug deeper I could see that the default configuration that React Native sets for Fresco will have a cache size of about 1/4 of your apps upper allocated memory limit (which will be higher for powerful devices like my Pixel and lower for low-end ones like that HTC Wildfire your Dad is still using).
- The question I was asking myself was how do I configure Fresco in a React Native app?
- Turns out this is quite easy (once I dug through the React Native Java code and worked out how) so let me show you…In your android folder of your React Native project open MainApplication.java and update the getPackages() method like so…You’ll notice I’m creating a new Fresco configuration and passing in a custom Supplier to which looks something like this…I’ve kept my custom cache configuration pretty much the same as the default because I like that it caters for low-end devices but feel free to use any configuration you want.

- This feature is built right into Chrome and it lets developers inspect pages and edit or remove elements right from within the browser.
- Facebook’s team created the React.js library which abstracts a layer for frontend developers to reuse certain UI elements.
- And now, with React Developer Tools you can inspect these element hierarchies and edit them right on the page.
- You can also study the different states and the paths of object trees including which elements are above & below other elements.
- In the sidebar, you can browse through props and states which let you study the behavior of other elements in that same tree.
Every web developer should already know about the amazing Chrome Developer Tools. This feature is built right into Chrome and it lets developers inspect pages

- Folks from the Chakra team showed off support for time travel debugging in Node at the NodeSummit .
- The node process is then started with a -TTReplay flag that replays the actions.
- In the VSCode ReactNative debugger, we replace Chrome with a Node process that VSCode can attach to, as a debugger.
- Putting these together, I was able to enable time travel debugging for ReactNative using VSCode and Chakra core – is a demo.
- In a previous blog post , I had also explained how I was using a node process to enable VSCode debug ReactNative apps.
