I am new to react native and expo.
This is the module i am looking at: https://github.com/leesiongchan/react-native-esc-pos
I want to build an app that can print using bluetooth thermal printer. I am not sure if i should build it using react native or expo. Please advise me.
Thank you.
Expo has its own limitations and there are even some bugs there too, Its good for quick development as the documentation suggests the same that it is good to get you started with development within minutes without much hustle. In my opinion, React Native CLI is most of the time the best option even if you are new to react native development. Because of the following reasons
You will learn a lot as you will get your hands dirty in core react native app development.
You won't have to deal with expo limitations
You won't have to be dependent on expo tools
Any Library which requires linking or contains native modules will not work with the expo.
The library you mentioned uses many native modules and usually these type of libraries are not supported and that is the reason why they've built their own APIs and Native Components you can read this,
the developer has not mentioned Expo support anywhere on the docs but still You can open an issue on GitHub and ask the developer if it supports EXPO platform or not, or maybe instead of asking you can try the library yourself and you will find out if its working or not,

I'm building a React Native App for a Chinese Company. I'm using Expo.
I really would love to use Google Maps, but it is not allowed there...
The best solution I found was to use Baidu Map,
I searched for SDKs and found some of them in GitHub.
I decided to use this one: https://github.com/qiuxiang/react-native-baidumap-sdk
which provides great documentation.
Although, I'm having some trouble implementing it to the app. I think that they don't support expo.
Does anyone here ever have a similar problem?
Or used another map...
Would really save my life!
This library uses native (Android & iOS) SDKs and provides a React Native API on top of them. Expo does not yet support custom native modules, which means you'll have to eject from it to use this package (or any other that uses BaiduMap or other native code).
I'm guessing they probably have a web based JS SDK instead which you could try to integrate into your app via a <WebView /> instead?
It is a question to professional developers at react-native. My react-native application needs augmented reality in it to develop complex games. I tried using viro-react, if you know this package. Developers of viro-react gave up on the package:
Not supported on IOS anymore
Documentation for some components is missing or poor
Are here people who is successfully using AR in their apps? Can you please tell me how you are doing it (different package or native components)? If it is native components, can you please tell me in a nut shell how to use native components with AR?
Thank you
Viro is actually a company that no longer exists, so don't hold your breath waiting for them. You can try using this example that works on both Android and iOS if you really want to use viro.
From my experience, there is no great solution to building AR apps in react native. You can also build the AR part of your app in Unity and import it into your app using this package.
Might be a duplicate, didn't find one tho.
I started a new application with the react-native-cli.
I want to use expo for development purpose:
Running on devices through Expo.
Publishing through Expo.
Is such a thing possible?
Copy pasting your 2 questions in Google and the first result...
1.
https://docs.expo.io/versions/latest/guides/testing-on-devices/
2.
https://docs.expo.io/versions/latest/workflow/publishing/
any questions left???
No, its not possible, in the docs its explicitly mentioned you can choose either the expo path or bare react native path. And if you choose expo you can eject from it to pure react native but cant go vice versa because the expo wrapper cant be implemented on the bare app.
so you have to again build an app with expo-cli to use expo publishing facilities etc.
but if you want to use expo modules in bare react native app you can do by using react-native-unimodules .
rn-unimodules
hope it helps. feel free for doubts
If anyone is ever looking for the answer it is stated here:
https://docs.expo.io/versions/v35.0.0/introduction/managed-vs-bare/#bare-workflow
It clearly states that in "bare" workflow you cant use the build services of Expo.
I'm considering building mobile apps in React Native using Expo and I noticed under FAQ that existing React Native projects can be converted to Expo.
What exactly are we converting? I really like staying as pure and clean as possible without too many abstraction layers in the middle which can obscure my ability to understand what's really happening for things to work in the app.
I'd appreciate a bit more clarification about what's really happening in the conversion process and what Expo is adding to the existing project.
This topic is covered in the Expo XDE readme.
However, we didn't get it working and decided to port our code into the default Expo app (Edit: after hitting a lot of issues porting our app to Expo, we decided to revert to vanilla RN).
There are at least a few required steps missing from the documentation:
Create exp.json file
Update React and React Native libraries to the versions required by Exponent
"react": "16.0.0-alpha.6",
"react-native": "https://github.com/expo/react-native/archive/sdk-16.0.0.tar.gz",
We summarized on our blog why we gave up on Expo in its current form.
I just started using React Native a few days ago and want to build my next iOS/Android app with it. However, I had a question (and I apologize in advance if this question is very basic).
If I am integrating my iOS and Android apps built with React Native, with an external service (like Salesforce for example), how do I go about using the native mobile SDKs they provide for iOS and Android? As in, what do I do to integrate those SDKs into my React Native app? Those SDKs are using native Objective-C and Java code, so how would I be able to use the JS code for React Native? I believe my understanding about this is skewed.
I looked at this link which goes into it, but it seemed very confusing and I had a bit of a hard time grasping the concept (again, I am very new to this - I've done a lot of web development, hence turning my attention to React Native, but I've done no mobile development whatsoever).
If someone could please explain how that works, and point me in the right direction where I can read and learn more, I would sincerely appreciate that!
Thank you!

Update:
There are react native packages build by open react native community if you couldn't find anything to access native iOS or android functionality you will have to write react native wrapper yourself using react native "Native Modules"
