Development instructions

Code Design

The project is based on

• Electron + NodeJS (the required version of NodeJS >= v12.)

• Typescript

• React + Redux

• Rust for some modules

Setup Environments

Install System Libs

You need libudev, libusb-1.0-0, libusb-1.0-0-dev installed on Linux

On Ubuntu:

sudo apt-get install libudev-dev libusb-1.0-0 libusb-1.0-0-dev

Install NPM packages

Install development tools

npm install -g node-gyp lerna yarn

For windows run also:

npm install -g npm windows-build-tools@4.0.0

Install dependencies:

yarn install

Run for development

Build sources

lerna run build

Optionally you can build desktop app with automatic rebuild on change. Please note that it rebuilds only main Desktop module, and you have responsibility to rebuild other modules manually when changed.

Continuous rebuild of Desktop (optional):

npm --prefix packages/desktop  run build:all:dev

Start Electron application:

lerna run start:electron

or

npm --prefix packages/desktop run start:electron

Troubleshooting

Cleanup

If you’re facing some weird problem it makes sense to make a full cleanup and then rebuild everything from scratch.

To erase NPM modules (may be needed when you build under different NodeJS version):

yarn run clean:node_modules

Erase compiled Javascript (it’s also done automatically on build):

yarn workspaces run clean

Emerald Vault module error

Electron may show error, like:

[emerald-vault-native] was compiled against a different Node.js version using NODE_MODULE_VERSION 64. This version of Node.js requires NODE_MODULE_VERSION 69. Please try re-compiling or re-installing the module (for instance, using npm rebuild or npm install)

At this case you’ll need to recompile Emerald Vault for your platform and version of Electron. You will need to have Rust compiler and LLVM installed, please follow instructions on:

• https://rustup.rs/

• http://releases.llvm.org/download.html

After installing Rust and LLVM run following to recompile the module:

export RUSTFLAGS=-C target-feature=+crt-static
npm run build:neon

Logs

Electron and Emerald logs persisted in:

• OSX: ~/Library/Logs/EmeraldWallet/log.log

• Linux: ~/.config/EmeraldWallet/log.log

Building distributions in development

You can run a distribution build in your development environment.Assuming you’ve already compiled ./src/ and ./electron/, you’ll be able to run:

yarn build:dist

This command will build for your current system. Note that there are configurations for several systems (OSX, Linux, Windows) specified in the "build" field of package.json, but the dist command will by default only build for the system it’s on.

Note	If you’re developing on OSX and have a developer signing identity on your machine, you can optionally disable that with CSC_IDENTITY_AUTO_DISCOVERY=false.

OSX is also able to build for Linux. Add -ml to that raw command to build for both OSX and Linux at the same time.

Troubleshooting

Some preliminary things to try in case you run into issues:

Clear out any persisted settings or userdata from previous trials

• OSX: ~/Library/Application Support/EmeraldWallet

• Linux: ~/.config/EmeraldWallet

• Windows: %APPDATA%\EmeraldWallet

Run tests

yarn test:watch

or for single run:

yarn test
