Fetching an API (Simple GET Request) with Loading Spinner in React Native App

Hi everyone!
Today I am going to show you how to make a GET request to an API from a React Native app. I will also show you how to use useEffect to ensure the API is only called on the React component mounting. While the API call is loading we will display an ActivityIndicator on screen to indicate loading and improve user experience.

// ABOUT ME
My name is Chelsea and I started studying software engineering in 2010. I have been working commercially full time since 2014 and have been in various positions from graduate developer to tech lead to solution architect.
I'm a full stack developer with a lot of experience in C# and Javascript but my passion is for mobile development; specifically native iOS development and cross platform using React Native.
I always have many things on the go and am always trying out a new side hustle and failing at it; perhaps you can learn from my mistakes!

Thank you! If you want to see how to make different types of api requests eg put, post and delete… I have recently uploaded a video covering these!

[@lylemccalmont4771]

Thank you for this @MissCoding - excellent tutorial for simple API connectivity. I get the same error "undefined is not an object (evaluating 'response["bpi"]') If I remove the line return Bitcoin (GBP): {response["bpi"]["GBP"].rate}; and readd it it works first time but then fails every time after. Any idea what the issue is @MissCoding?

[@kashif2309]

I'm getting an error saying "undefined is not an object (evaluating 'response["bpi"]')

[@anilokcuoglu]

i get the same error can you handled this ?

[@christopherquarshie8258]

Same error any solution?

[@mehdimv4808]

​@@christopherquarshie8258 First cut the "return Bitcoin (USD): {response["bpi"]["USD"].rate};return Bitcoin (USD): {response["bpi"]["USD"].rate};" and save so the app runs successfully one time, then paste it and save again and it works for some reason!
