Not performing unit tests
Another typical error that Reacts Native developers makes while creating react native apps is failing to complete unit testing. Most developers overlook this step since they are accustomed to working without written unit tests. Moving on in the development process without a unit test in place, on the other hand, might be a hazardous move.
Addressing faults and difficulties at the last minute or after the product has been released can be a difficult undertaking. When a product with flaws is made available to the public, it produces a poor impression of both the product and the brand. The easiest method to avoid it is to test its functioning and guarantee that all components are fully functional before releasing the product. Unit testing is highly useful in this situation.
Unit tests enable developers to test individual units or components of an application to ensure that they are performing as planned. This is done during the development stage (code phase) to assist developers to save time and money in the long run.
Inside the render function, change the state
Data contains all of the information about the component that will be displayed on the state. It retrieves information from the store and shows it on the screen. React offers a method called set state () that accepts the new object state and compares it to the previous state. After that, add the new state to the old state and circulate the data.
This cycle will last a lifetime. When you directly alter the state, the life cycle is disrupted, and all prior states may be corrupted. The appliance may occasionally behave improperly or crash. When this happens, you’ll lose track of all states and may end yourself writing bespoke code instead of React. As a result, these solutions are possible if you directly alter the state. To avoid this disaster, you’ll construct a child component for the function’s content and send it down as a prop. By implementing the render function, we can make the value mutable.
Abstraction Layer Constraints
To provide the finest functionality, you must add an abstraction layer to the React Native framework, which you may do in the local stage. This layer, in and of itself, brings with it several recurring concerns – and you must take precautions to avoid them
Identifying the bugs you face in the abstraction layer. When you have bugs, it might lead to a slew of problems.
Reliance on third-party libraries and services is high.
Reliance on the execution of bespoke designs
