Berkenalan dengan Expo : Salah Satu Sahabat Developer React Native

Status : Draft 

Catatan penting, Expo mungkin tidak cocok dengan kebutuhan Anda, pastikan untuk membaca Why not Expo? [3] terlebih dahulu.

Utilitas ini sangat memudahkan, jika ingin membuat standalone app untuk dipublish di Playstore atau AppStore, bisa membaca [2].

Jika dalam mengikuti instalasi exp di [2] , menggunakan npm :

npm install -g exp

mengalami error, seperti ini misalnya :

> @expo/traveling-fastlane-linux@1.0.15 preinstall /usr/local/lib/node_modules/exp/node_modules/@expo/traveling-fastlane-linux
> node platform.js

/usr/local/bin/exp -> /usr/local/lib/node_modules/exp/bin/exp.js

> spawn-sync@1.0.15 postinstall /usr/local/lib/node_modules/exp/node_modules/spawn-sync
> node postinstall


> @expo/ngrok@2.3.0 postinstall /usr/local/lib/node_modules/exp/node_modules/@expo/ngrok
> node ./postinstall.js

coba lakukan instalasi menggunakan yarn :

sudo yarn global  add exp
