:warning: Disclaimer: this project is under active development. Use at your own risks.
## Installation
#### Requirements
Project has been tested under [NodeJS ](https://nodejs.org ) v9.3.0, with [Yarn ](https://yarnpkg.com ) v1.3.0 and [Python ](https://www.python.org/ ) v2.7.10 (used by [node-gyp ](https://github.com/nodejs/node-gyp ) to build native addons). You will also need a C++ compiler.
#### Setup
1. Install dependencies
```bash
# app dependencies
yarn
# npm packages flow definitions
yarn flow-typed
```
2. Create `.env` file
```bash
# ENV VARIABLES
# -------------
# Where errors will be tracked
SENTRY_URL=http://...
# OPTIONAL ENV VARIABLES
# ----------------------
# Developer tools position (used only in dev)
# can be one of: right, bottom, undocked, detach
DEV_TOOLS_MODE=bottom
# Filter debug output
DEBUG=lwd*,-lwd:syncb
```
#### Development commands
```bash
# Launch the app
yarn start
# Launch the storybook
yarn storybook
# Code quality checks
yarn lint # launch eslint
yarn prettier # launch prettier
yarn flow # launch flow
yarn test # launch unit tests
```
#### Building from source
```bash
# Build & package the whole app
# Creates a .dmg for Mac, .exe installer for Windows, or .AppImage for Linux
# Output files will be created in dist/ folder
yarn dist
```
**Note:** Use `yarn dist:dir` to speed up the process: it will skip the packaging step. Handy for debugging builds. You can also use `BUNDLE_ANALYZER=1 yarn dist:dir` to generate [webpack-bundle-analyzer ](https://github.com/webpack-contrib/webpack-bundle-analyzer ) report.
