## Introduction

[Mission Statement](./MISSION.md)

[Internal documentation](./docs#documentation)

## Developing Compatible Dapps

If you're a web dapp developer, we've got two types of guides for you:

### New Dapp Developers

- We recommend this [Learning Solidity](https://karl.tech/learning-solidity-part-1-deploy-a-contract/) tutorial series by Karl Floersch.
- We wrote a (slightly outdated now) gentle introduction on [Developing Dapps with Truffle and MetaMask](https://medium.com/metamask/developing-ethereum-dapps-with-truffle-and-metamask-aa8ad7e363ba).

### Current Dapp Developers

- If you have a Dapp, and you want to ensure compatibility, [here is our guide on building MetaMask-compatible Dapps](https://github.com/MetaMask/faq/blob/master/DEVELOPERS.md)

## Building locally

 - Install [Node.js](https://nodejs.org/en/) version 8.11.3 and npm version 6.1.0
 - Install dependencies:
   - If you are using nvm (recommended) running `nvm use` will automatically choose the right node version for you.
 - Install gulp globally with `npm install -g gulp-cli`.
 - Build the project to the `./dist/` folder with `gulp build`.
 - Optionally, to rebuild on file changes, run `gulp dev`.
 - To package .zip files for distribution, run `gulp zip`, or run the full build & zip with `gulp dist`.

 Uncompressed builds can be found in `/dist`, compressed builds can be found in `/builds` once they're built.

### Running Tests

Requires `mocha` installed. Run `npm install -g mocha`.

Then just run `npm test`.

You can also test with a continuously watching process, via `npm run watch`.

You can run the linter by itself with `gulp lint`.

## Architecture

[![Architecture Diagram](./docs/architecture.png)][1]

## Development

```bash
npm install
npm start
```

## Build for Publishing

```bash
npm run dist
```

#### Writing Browser Tests

To write tests that will be run in the browser using QUnit, add your test files to `test/integration/lib`.

Began adding browser-native encryptor module Added new Qunit build process that will browserify the contents of `test/integration/lib` into the QUnit browser, allowing much more modular testing, including unit testing of our modules in our target browsers. Made a basic unit test file of this form for the new encryptor module, which fails miserably because I've only just begun to work with it. I've started with this blog post as a starting point, and will be adjusting it to our needs from there: http://qnimate.com/passphrase-based-encryption-using-web-cryptography-api/ 2016-10-13 05:03:14 +02:00			`#### Writing Browser Tests`
