Clojurians Log v2

I'm amazed how much better RN dev has come in the last two years.

It definitely has improved 🙂 My first project with CLJS + RN was back in 2016. I would say the Expo “bare” workflow is quite nice nowadays. That’s the main difference for me.

I’m using the following library like so:

https://github.com/zhangtaii/react-native-google-place-picker

(:require ["react-native-google-place-picker" :default RNGooglePlacePicker])

(defn add-address [navigation]
  (.show RNGooglePlacePicker
         (fn [response]
           (prn "response is " response)
           )))

But I’m getting the following error:

How to fix this?

basically doing (js/console.log RNGooglePlacePicker) prints null. What am I doing wrong?

try

(:require ["react-native-google-place-picker" :as lib])

@raspasov with :as it prints

{"default": null}

Since the documentation says do:

import RNGooglePlacePicker from 'react-native-google-place-picker';

Hmm… Not sure, I am not familiar with shadow-cljs but I doubt it’s a problem from shadow per se. Things to try: • Did you link everything properly? • Always need to rebuild from xcode when adding a new library that requires native code • Clean your xcode caches, rebuild again • Restart your shadow/etc ClojureScript server processes

{"default": null}

Also, always restart yarn/npm when adding a new lib.

I am not 100% certain in the necessity of all steps, but I struggled for a few weeks initially with RN to get everything working around libs, so I do all of the above without questioning it much when adding a new lib.

@raspasov the documentation says react-native link for automatic link

Do I have to do a manual link?

Usually not.

If you’re on a recent React Native version.

that’s right I am on a recent version

react-native: 0.63.4

That should be ok then, if it reports all linked properly when you added the lib initially.

yes I rebuilt from xcode

Have you tried without the “” react-native-google-place-picker ?

I believe “” are only needed if the lib starts with @

yes I tried without the apostrophes but still getting null

how to clean xcode cache?

I clean it using Menu Bar -> Product -> Clean Build Folder

I also restarted shadow-cljs server process

@ps please read the doc section specifically about the default exports. https://shadow-cljs.github.io/docs/UsersGuide.html#_about_default_exports

you do have the correct translation using :default but unfortunately that doesn't automatically mean that it is correct. so definitely try :as as well

beyond that shadow-cljs does not process any dependencies for RN projects. so maybe you need to restart the metro stuff and reset its indexes
