Instagram Clone React Native Tutorial 2021 👨‍💻 I'll show you how you can do this in the simplest way and terms possible. By the end of this series you'll have learned how the big companies do it and will be able to do the same, you not only will be able to do this app, but you'll be able to put what you learn into your very own projects! In this series, we use React Native with Expo to quickly deploy the project. We use firebase for all our microservice needs like the auth system, database, storage, amongst others. firebase, redux, react native, javascript, expo. In this series, we'll use all of them and you'll learn them by doing an iconic app. Welcome to this Simcoder project and make an Instagram Clone!

const uid = snapshot..query.C.path.segments[1]; For me the path was different from the one in the tutorial, so try this it might help

cerovcecblaze commented 3 years ago

A potential solution is to use:

const uid = snapshot.docs[0].ref.path.split('/')[1];

and put that line^ and the rest of the code in that function in a try catch block. The line above will throw an error if there is no documents (posts), so for users where this throws an error, just catch, and do nothing since its pointless to get the posts of a user with no posts.

I think you should console.log(snapshot) for yourself and try to find the segments data based on the console.log, the snapshot data might be different because firebase might update their way to display the snapshot. For my part i was able to retrieve the data from snapshot..query.C.path.segments[1];

I'm facing the same issue when fetching userlikes (((snapshot.ZE.path.segments[3];))))), any solutions???

This worked for me when fetching user posts, any solution for user likes instead of snapshot.ZE.path.segments[3] ???

What does _C_ mean? (I tried googling before posting).
