The library ‘jsonwebtoken’ is a popular way to create and verify a JWT token. That’s how to use it synchronously: import { sign } from 'jsonwebtoken'; const token = sign( { yourData: whateverYouWant }, // your payload yourSecret, { algorithm: 'HS256' } ); If you want to use it asynchronously…

After the Facebook Login you get an access token by Facebook. To turn your access token into consumable data you just need to create a GET request with the following URL: https://graph.facebook.com/me?access_token=<your-fb-token>& fields=id,name,email,picture.width(640).height(640) The important aspect of me after graph.facebook.com is that you just need the token, not the explicit Facebook ID.

A Set object is a collection that allows unique items only. You can use this property by converting your array into a Set and then convert it into an array again. Let’s define a simple utility function: const cleanDuplicates = (arrayWithDuplicates) => { return Array.from(arrayWithDuplicates) } Now use it: let initialArray = [1,1,2,2,3,3,4,4,5,5]; let finalArray = cleanDuplicates(initialArray); // finalArray -> [1,2,3,4,5]

Caching in the react native packager can lead to annoying issues. It is started automatically as you type “react-native run-<platform>”. To avoid starting it with cache, you can open two terminals. In your package.json you have: ... "scripts":{ ...

You don’t always want the debugger turned on because in some cases it makes the whole process very slow. To get real time info from the app you can just use console.warn: console.warn(whatever_you_wanna_show); Essentially, console.warn prints out the yellow horizontal sections you often see in your app. It is not meant to be used this way, but it’s very useful in these cases.
