Status, a Mobile Client for Ethereum 2.0

#Buidl Status Yourself and Participate in a Better Web

The easiest way

1. Clone the repository

git clone https://github.com/status-im/status-react
cd status-react

2. Install the dependencies

We created a special script that installs everything Status needs. However, this script works only
for macOS and Ubuntu Linux. If you use another Linux distribution, please, install all dependencies manually (you can find the list below).

It’s also better to make sure that you have Node Version Manager installed before running this script.
The reason is simple — NVM provides much more flexibility and allows to have several NPM versions installed.

Just run this to install all dependencies:

make setup

This script prepares and installs the following:

• Homebrew
• Java 8 (from Homebrew on Mac and from ppa:webupd8team/java on Ubuntu)
• Clojure and Leiningen
• Node.js (see note below)
• yarn 1.12.3
• React Native CLI and Watchman
• Android SDK
• Android NDK r10e (under ~/Android/Sdk/)
• Maven
• Cocoapods

Note 1: It can take up to 20 minutes depending on your machine and internet connection speed.

Note 2: If you don’t have nvm, node@10 will be installed from Homebrew.
If you don’t have nvm AND already have node installed on your machine then nothing will happen.

Running development processes

After you installed all the dependencies, you need to run two processes — the build process and React Native packager. Keep both processes running when you develop Status.

1. Build process

Just run one of these commands in the first terminal window:

make startdev-ios-simulator
make startdev-ios-real
make startdev-android-avd
make startdev-android-genymotion
make startdev-android-real

By doing this you will start the compilation of ClojureScript sources and run re-frisk (a tool for debugging).

For additional information check the following:

• clj-rn;
• re-frisk.

2. React Native packager

Do this in the second terminal window:

make react-native

Build and run the application itself

iOS (macOS only)

Just execute

make run-ios

If you wish to specify the simulator, just run make run-ios SIMULATOR="iPhone 7".
You can check your available devices by running xcrun simctl list devices from the console.

You can also start XCode and run the application there. Execute open ios/StatusIm.xcworkspace, select a device/simulator and click Run.

Note: Of course, you need to install XCode first in both cases. Just go to Mac AppStore to do this.

Android

Installation script installs Android NDK, but you still need to install Android SDK manually to build and run Status on Android.

The easiest way to do this is to install Android Studio — it will install almost everything for you.
There is a difficult way for those who don’t want/need Android Studio.

In this case you have to do the following:

• Install Android SDK from you package manager (brew install android-sdk, sudo apt-get install android-sdk, …) or download it manually here;
• Add several env variables to your profile (.bashrc, .zshrc, …) — installer should say what are these variables and their values;
• Run android update sdk --no-ui to update SDKs;
• Run sdkmanager from your machine and install the latest Android SDKs;
• Optional: If you want to use AVD (Android Virtual Device, emulator), please, check this documentation;
• Optional: If you don’t like AVD, you can also use Genymotion;

• Execute:

  make run-android`
  

Errors like android-sdk-16 not found usually mean that you simply need to install missing SDKs. Run sdkmanager for that.

Check the following docs if you still have problems:

• macOS;
• Ubuntu Linux;
• Arch Linux (can also be useful for other Linux distributions).

Optional: Advanced build notes

Node.js

There are several ways of installing Node.js on your machine.
One of the most convenient and easy is by using Node Version Manager (nvm). However, our setup script installs node from Homebrew if nvm is not installed on your machine.

That’s why we suggest installing nvm first if you want to have a more flexible development environment.

If nvm is already installed, make setup simply does the following:

nvm install 10
nvm alias status-im 10
nvm use status-im

Custom Android SDK location

Some developers prefer to use Android SDK integrated in Android Studio. Of course, it doesn’t matter
for the build process — just make sure that ANDROID_SDK_ROOT points to a right location and you have all the SDKs installed.

Locally built status-go dependency

If you need to test a mobile build with a custom locally built status-go dependency, you can build it by following this process:

1. Ensure the STATUS_GO_HOME environment variable is set to the path of your local status-go repo (see Build status-go page for more information on requirements);
2. From the root of the status-react repo, run scripts/bundle-status-go.sh <platform>, where platform can be android or ios;
3. This will generate a build artifact under the status-react repo, and will be considered prioritary in the dependencies until it is deleted (e.g. by running make clean or make prod-build).

NOTE: Desktop builds currently always download and build status-go locally.

Debugging tips

Inspecting app DB inside Clojure REPL

E.g. if you want to check existing accounts in the device, run this function in the REPL:

(get-in @re-frame.db.app-db [:accounts/accounts])

Inspecting current app state in re-frisk web UI

Assuming re-frisk is running in port 4567, you can just navigate to http://localhost:4567/ in a web browser to monitor app state and events.

Troubleshooting

I have issues compiling on Xcode 10

Some developers are experiencing errors compiling for iOS on Xcode 10 on MacOs Mojave:

error: Build input file cannot be found:

'status-react/node_modules/react-native/third-party/double-conversion-1.1.6/src/cached-powers.cc'

To fix similar errors run the following commands:

make clean

cd ios
pod update
cd ..

cd node_modules/react-native/scripts && ./ios-install-third-party.sh && cd ../../../

cd node_modules/react-native/third-party/glog-0.3.4/ && ../../scripts/ios-configure-glog.sh && cd ../../../../

Now you should be able to compile again. The issue reference is here.

I get a compilation error when running clj -R:dev build.clj watch

Some developers see the error Exception in thread "main" java.lang.NoSuchFieldError: VAR, compiling:((..)/status-react/build.clj:1:1) when running the clj -R:dev buid.clj watch command (e.g., via make startdev-android-avd).

This happens when you are running an earlier version of Clojure that is incompatible with cljs.build.api. The solution is to upgrade to the latest version of Clojure. E.g., for macOS

$ brew upgrade clojure
==> Upgrading 1 outdated package:
clojure 1.9.0.302 -> 1.9.0.397
