- Now here are the two ways the animation could be put in place.Use the Animated API and handle all the movements ( which in this case are simple to be fair ) between the two modes in a relatively complicated way by having one view move off screen when the…
- Use the LayoutAnimation API to essentially configure how changes in the layout are to be handled.Now here is my thought process, the Animated API is pretty strong but it involves writing a lot of code for something that is very simple.
- The API works for both iOS and Android but to make it work on Android you have to add the following lines to your file.This can go anywhere in your file.This needs to go in the constructor.Now some things to keep in mind, LayoutAnimation handles the way layout changes are handled…
- Now I decided to stick with linear but the fact that views didnt hide fast enough was a minor ( not for me ) annoyance, but luckily LayoutAnimation also supports custom animation configurations.The config for LayoutAnimations require a duration for the animation and optionally you can also give custom configs…
- The type property indicates the animation type to be used and property is used to indicate what is to be animated.Animation types can be of the property can beNow I was happy with just animating the opacity of the views when deleting and updating but I gave the delete a…
So first things first this article is simply my opinions on React Native’s LayoutAnimation API, it is not a guide on how to use the API but simply a description of the all that I have learnt about…

- I am currently working as a freelance full-stack developer.
- Parket is a state management library; a well-known example would be Redux.
- Parket lets you create models with a state, actions, and views; these can later be used by instantiating them and can be nested inside each other.
- As you can see here, Parket doesn’t care what your action does or instead what it is; it just listens to state changes.
- It’s always nice to see new approach to state management.
State management is one of those topics that divides opinions. So far we’ve seen a couple of option…

- So, in order to reuse some domain logic like a Payment feature you will need to enter in every function folder and move the respective files and tests to a separeted folder to create a lib.
- Problems solved… In parts…I think that the views(visual components/dumb components) are not part of the domain because the views are just a way to decorate some data to display to the user.
- It’s the best part to use and reuse components.Then, I extracted the views from all domains folder and created a components folder in src directory.
- Therefore, after some reflection, I decided to create a folder called modules and put all the logical domain inside.Another point that I think that is important to care about is the screens folder.
- The answer to this is because the components folder is for reusable visual components(dumb components) as opposed to screens which are very coupled with the current application.The utils folder is used to keep some logic that can be extracted from the code but is not about the application domain, e.g. string/array operations.If you have a differente point of view, let me know.
In this post, I will share with you how I organize my React & Redux projects and talk about some decisions that I made while working in some projects in the last two years. This structure groups each…

- Your views and components should rely on props and callbacks.
- The idea is simple:Screens and Views are not the same.
- FavoritesScreen uses that callback to tell the view to navigate to another screen.
- Keep your callbacks chained togetherEvery time one of your views exposes a callback which may be declared in another part of the app (for example, mapStateToProps), first invoke the actual callback passed on props.
- This enables you to, for example, Navigate to a screen and also fetch some information to feed the next view.Following the previous example, if FavoritesScreen told FavoritesView to navigate to the FavoriteScreen when selecting a Favorite, Redux would honor that, but also invoke some Redux actions.As you may see, every realm knows how to handle its stuff: Screens know how to navigate, Connected Views know how to handle redux actions and Views are dumb, stateless and rely on their props.5.
I’ve been working with React Native for quite a while now, both professionally and personally, and actually enjoy it. In this article I will describe some patterns I use. Keep in mind that whatever…

- It complements React’s composable view components by utilizing a unidirectional data flow.Flux has 4 major / React ComponentsThe unidirectional data flow allows Flux to shy away from the what we’re more familiar with — the MVC structure.MVC Structure and FlowWhen a user interacts with a React View, it kicks off an action through the dispatcher, to the stores that hold the data, which then updates all of the views that are affected.Flux Structure and Data FlowThe unidirectional pattern means that data flows in a single direction.
- The action, dispatcher, store, and view are independent nodes with distinct inputs and outputs.
- The actions are simple objects containing new data and an identifying type property.Sometimes, the views may cause a new action to be sent through the system depending on the UI.Actions are provided to the dispatcher through action creators originating from the views, through user interaction.
- The dispatcher, acting as a central hub, will then take those actions and invoke callbacks registered by the stores and send the actions to the stores.
- These views will listen for that change event through event handlers will call their own setState() method to then re-render themselves and all of their descendants in the component tree.Flux, with Harry PotterSeverus Snape is patrolling the halls of Hogwarts to make sure no students are out of bed.
When I first started researching Flux, it was described as an application architecture. I thought, “Great, I know architecture, this should make sense.” Little did I know, architecture in the tech…
