Giveth Dapp for crowdfunding and managing donations on the ethereum blockchain.

DApp - Donation Application for charitable giving without losing ownership

Welcome to the code for Giveth's DApp. This is an open source effort to realize the potential of ethereum smart contracts. More specifically, the Giveth DApp provides an alternative to traditional donation.

Getting Started

In the following sections you will learn all you need to know to run the DApp locally and to start contributing. All the steps are also described in this amazing Video Tutorial Walkthrough by Oz.

Prerequisities

• You need to use Node > v8, however, v10 does not work correctly yet.
• You need to use npm > v5.4, or yarn > v1.6 to correctly install the dependencies.

Install

1. Click Star on this repo near the top-right corner of this web page (if you want to).
2. Join us on Riot if you haven't already.
3. Fork this repo by clicking Fork button in top-right corner of this web page. Continue to follow instruction steps from your own giveth-dapp repo.
4. Clone your own "giveth-dapp" repo. Copy the link from the "Clone or download" button near the top right of this repo's home page.
5. The rest of these steps must be done from your machine's command line. See the OSX and Linux or Windows section to continue.

OSX and Linux

1. From the desired directory you wish to copy the "giveth-dapp" folder with source files to.

   git clone {paste your own repo link here}
   

   NOTE: Please use develop branch for contributing.

   git clone -b develop {paste your own repo link here}
   

2. Change directories to giveth-dapp:

   cd giveth-dapp
   

3. Make sure you have NodeJS (v8.4.0 or higher) and npm (5.4.1 or higher) installed.
4. Install dependencies from within giveth-dapp directory:

   npm install
   

5. That is it, you are now ready to run the giveth-dapp! Head to the Run DApp section for further instructions.

Windows

1. Make sure you have the LTS version of 64-bit NodeJS (v8.9.1)
2. Run the node-v8.9.1-x64.msi installer and then continue through the installation as normal. Be sure to have the "Enable in PATH" option enabled before installing.
3. Open the command line in administrator mode by right clicking on the cmd.exe application and selecting "Run as administrator"
4. In the administrator command prompt, change to the directory where you want to store this repository.

   cd C:\some\directory\for\repositories
   

5. Update npm to the latest version (in order to make sure the next step has the latest dependencies to install) with:

   npm install npm@latest -g
   

6. You must install the NodeJS/NPM dependcies for Windows before you are able to continue. This command will take a few minutes to install all of the necessary dependencies for building NodeJS applications on Windows.

   npm install -g windows-build-tools
   

7. Install dependencies from within giveth-dapp directory:

   npm install
   

8. For some reason the npm node-sass package does not install correctly in windows when using the 'npm install' command, so you must rebuild the node-sass package with:

   npm rebuild node-sass
   

9. The web3 package does not install correctly when using the 'npm install' command, so you must install it separately in order for this dapp to run. Use the following to install web3:

   npm install web3
   

10. That is it, you are now ready to run the giveth-dapp! Head to the Run dapp section for further instructions.

Run

1. The Giveth dapp will need to connect to a feathers-giveth server. Follow the feathers-giveth readme instructions to install and run server before proceeding further. Alternatively, you could change the configuration to connect to the develop environment, see the Configuration section.

2. Start the dapp.

   npm start
   

3. Once the dapp is up in your browser, click "Sign In" from the main menu.

4. For testing locally, choose any of the wallet files found in the giveth-dapp/keystores/ folder using the wallet password: password. DO NOT USE THESE ON ANY MAINNET EVMs.

5. Using the test token To use the test token you need to import the keystore.json you use for your account to MetaMask. After importing, click on 'Add token' > 'Custom token' and enter the MiniMe Token address that can be found when deploying the contracts (should be 0xe78A0F7E598Cc8b0Bb87894B0F60dD2a88d6a8Ab by default but make sure to check) The token balance should show up automatically and the token symbol is MMT. However, in the dApp the token symbol is referred to as ANT, b/c the dapp needs to be able to fetch a conversion rate.

NOTE: When resetting feathers or redeploying the contracts, you need to remove the keystore from metamask and follow this procedure again.

Build

npm run build

NOTE: due to some web3 libraries that are not transpiled from es6, we have to use our giveth-react-scripts fork of react-scripts .

Configuration

The DApp has several node environment variables which can be used to alter the DApp behaviour without changing the code. You can set them through .env or .env.local files in the DApp folder.

Variable name	Default Value	Description
PORT	3010	Port on which the DApp runs
REACT_APP_ENVIRONMENT	'localhost'	To which feathers environment should the DApp connect. By default it connects to localhost feathers. Allowed values are: localhost, develop, release, alpha, mainnet. See Deployment Environments.
REACT_APP_DECIMALS	8	How many decimal should be shown for cryptocurrency values. Note that the calculations are still done with 18 decimals.
REACT_APP_FEATHERJS_CONNECTION_URL	Differs per REACT_APP_ENVIRONMENT	Overwrites the environment injected feathers connection URL.
REACT_APP_NODE_CONNECTION_URL	Differs per REACT_APP_ENVIRONMENT	Overwrites the EVM node connection URL for making EVM transactions.
REACT_APP_LIQUIDPLEDGING_ADDRESS	Differs per REACT_APP_ENVIRONMENT	Overwrites the Liquid Pledging contract address.
REACT_APP_DAC_FACTORY_ADDRESS	Differs per REACT_APP_ENVIRONMENT	Overwrites the DACs contract address.
REACT_APP_CAMPAIGN_FACTORY_ADDRESS	Differs per REACT_APP_ENVIRONMENT	Overwrites the Campaign Factory contract address.
REACT_APP_MILESTONE_FACTORY_ADDRESS	Differs per REACT_APP_ENVIRONMENT	Overwrites the MilestoneFactory contract address.
REACT_APP_TOKEN_ADDRESSES	Differs per REACT_APP_ENVIRONMENT	Overwrites the bridged token addresses. This is a JSON object string w/ token name : token address.
REACT_APP_BLOCKEXPLORER	Differs per REACT_APP_ENVIRONMENT	Overwrites the block explorer base URL. The DApp assumes such blockexplorer api is \<BLOCKEXPLORER\>/tx/\<TRANSACTION_HASH\>
REACT_APP_DEFAULT_GASPRICE	10	Overwrites the default gasPrice that is used if ethgasstation service is down. The value is in gwei.

Example of .env.local file that makes the DApp run on port 8080, connects to the develop environment and uses custom blockexplorer:

PORT=8080
REACT_APP_ENVIRONMENT='develop'
REACT_APP_BLOCKEXPLORER='www.awesomeopensourceexplorer.io'

The rest of the configuration can be found in configuration.js

Analytics

Google analytics and Hotjar can be enabled per environment:

    analytics: {
      ga_UA: 'UA-12345678-1',     // Your Google Analytics tracking code
      useGoogleAnalytics: true,   // Whether to enable GA
      useHotjar: false            // Whether to enable Hotjar
    }

The following events are tracked with Google Analytics:

• pageviews
• signup
• signin
• creation of DACs/Campaigns/Milestones
• editing of DACs/Campaigns/Milestones
• making donations
• actions on milestones

DO NO USE ANY OTHER THAN DEVELOP ENVIRONMENT FOR DEVELOPING AND TESTING.

Query Strings

The milestone creation/proposal view now supports query string arguments! The following arguments are available:

Argument	Expected Values	Type
title	The title of the milestone	string
description	The description of the milestone	string
recipientAddress	The address of the recipient	string
reviewerAddress	The address of the reviewer	string
selectedFiatType	A valid fiat type (i.e. USD)	string
date	A valid milestone date string	string
token	A valid token symbol (i.e. DAI)	string
tokenAddress	A valid token address	string
maxAmount	A valid max amount of ETH or token	number
fiatAmount	A valid max amount of fiat (dependant on selectedFiatType)	number
isCapped	Determines whether the milestone should be capped	0 or 1 (boolean)
requireReviewer	Determines whether the milestone should require a reviewer	0 or 1 (boolean)

Contributing

The DApp is fully open-source software, and we would love to have your helping hand! See CONTRIBUTING.md for more information on what we're looking for and how to get started. You can then look for issues labeled good first issue or help wanted. We regularly reward contributions with ether using the Reward DAO.

If you are not a developer, you can still help us by testing new releases periodically. See the Release Process section.

If you want to better understand how does the development process works, please refer to our wiki pages, especially to the Product Definition, Product Roadmap and Development Process & Quality Assurance.

Local Development

At first you would like to run the DApp locally. When running testrpc locally in deterministic mode, you can use any of the keystores in the giveth-dapp/keystores as your wallet. This will provide you access to the testrpc accounts for local development. Each keystore uses the same password: password. DO NOT USE THESE ON ANY MAINNET EVMs

The keystores are seeded with 10.000 ANT tokens for testing donations. To get started with testing donations, make sure to add your account's keystore to MetaMask and swith MetaMask to Ganache. The donation modal should then show the appropriate balance when donating in ANT tokens.

NOTE: If you get a nonce error in MetaMask or if the dapp fails to load with your metamask unlocked, it could be b/c metamask is confused. You should go to "settings" -> "Reset Account" in MetaMask in order to reset the nonce & cached account data.

Development and PR Testing

1. The Giveth Dapp is auto deployed from the develop branch and is live on Rinkeby develop.giveth.io. All pull requests are autodeployed and the PR preview will be generated upon submission. To learn how to access PR previews see Development Process & Quality Assurance on our wiki.
2. In order to use the dapp you will need to create account. If this is your first time, click "sign up" to create an account. If you already have a valid keychain file, use it to sign in.
3. You will need test ether on the Rinkeby network. Go to the "wallet" page to see your new address (0x..). Copy that address and use the faucet to get some: https://faucet.rinkeby.io/

Deployment Environments

At Giveth, we are using the gitflow branching model to deploy to 4 different environments.

Name	Blockchain	Branch Deployed	Auto Deploy	Use
mainnet	Ethereum Main Network	master	no	Main network deployment for now abandoned due to high transaction costs until sustainable solution is found.
alpha	Rinkeby Test Network	master	no	Environment used as a production version until scalability is resolved.
release	Rinkeby Test Network	release	yes	Environment for release candidate quality control testing by non-devs.
develop	Rinkeby Test Network	develop	yes	Development environment for integrating new features. Feature and pull request branches are also automatically deployed to this environment.

You can change the environment to which the DApp connects through the node environment variables. See the Configuration section for more details.

Release Process

The development uses the Gitflow process with 2 weeks long sprints. This means there is new release to be tested every fortnight. We invite contributors to help us test the DApp in the release environment before we merge it to the master branch and deploy to production environments. If you are interested, write to the DApp Development channel on Riot. You can read more about the release planning on our wiki.
