How to install a local dev env in one click

This guide will walk you through how to install our learn project GoodBootstrap that will install all our sub projects: GoodServer , ​ GoodContracts, GoodDAPP and GoodGun

Prerequisites

Important: Use node version 14

The most easier way to manage node version is using nvm. Here's example how to set proper node version with it:

nvm install 14.17.6
nvm use 14.17.6
nvm alias default 14.17.6

Install build tools

# linux / macOS
> npm install -g node-gyp
# debian / ubuntu 
> sudo apt-get install build-essential
# macOS
> xcode-select --install

# windows
npm install -g --production windows-build-tools

Install mobile developer tools

IOS

• install / update to the latest xCode

• install CocoaPods:

sudo gem install cocoapods

Android

Follow the guides:

• macOS guide 1 guide 2

• ubuntu expanded guide

Quick start

DApp-only install

Clone the repository and install dependencies

git clone [e-mail]:GoodDollar/GoodDAPP.git
cd GoodDAPP
yarn --frozen-lockfile
cd ios
pod install

Important: always specify --frozen-lockfile yarn flag to keep packages to being updated. Otherwise you could get error during build because the latest versions of some packages aren't compatible for the RN version used.

Environment .env file

Copy .env.development to .env, then append .env file with the following creds:

REACT_APP_ALCHEMY_KEY=
REACT_APP_AMPLITUDE_API_KEY=
REACT_APP_AUTH0_CLIENT_ID=
REACT_APP_AUTH0_DOMAIN=
REACT_APP_AUTH0_SMS_CLIENT_ID=
REACT_APP_FACEBOOK_APP_ID=
REACT_APP_FACE_VERIFICATION_PRIVACY_URL=https://medium.com/gooddollar/gooddollar-identity-pillar-balancing-identity-and-privacy-part-i-face-matching-d6864bcebf54
REACT_APP_GOOGLE_CLIENT_ID=
REACT_APP_TORUS_NETWORK=ropsten
REACT_APP_TORUS_PROXY_CONTRACT=
REACT_APP_WEB3_SITE_URL=https://w3.gooddollar.org
REACT_APP_MARKET_URL=https://www.facebook.com/groups/gooddollarmarketplace
REACT_APP_SENTRY_DSN=

REACT_APP_SERVER_URL=https://good-server.herokuapp.com
REACT_APP_GUN_PUBLIC_URL=https://goodgun-dev.herokuapp.com/gun
REACT_APP_ZOOM_LICENSE_KEY=
REACT_APP_ZOOM_ENCRYPTION_KEY=

You could take missing creds from the Netlify's gooddev.netlify.app instance or ask your team leader for the complete .env file

Running the app

cd GoodDAPP
npm run web # browser
npm run ios # IOS
npm run android # Android

iOS hints

Don't forget to open ios/GoodDollar.xcworkspace (NOT .xcodeproj!) and set up provisional profile and developer account.

Install with the local server instance

Prerequisites

Install MongoDB 4.x:

• guide for macOS: https://docs.mongodb.com/manual/tutorial/install-mongodb-on-os-x/

• guide for Linux: https://docs.mongodb.com/manual/administration/install-on-linux/

Configure mongo to run as a cluster. Add your local computer's hostname or it's IP in the home network to the bindIp list:

# mongod.conf
systemLog:
  destination: file
  path: /usr/local/var/log/mongodb/mongo.log
  logAppend: true
storage:
  dbPath: /usr/local/var/mongodb
net:
  bindIp: 127.0.0.1,Alexs-MacBook-Pro-2.local
replication:
  replSetName: local

GunDB

Clone the repository and install dependencies

git clone [e-mail]:GoodDollar/GoodGun.git
cd GoodGun
npm i

The .env.example file provided is using mongoDB as the storage. Don't use it. For the local development, the direct filesystem should be used. To achieve this, create .env file with the following contents:

GUN_PUBLIC_S3=
GUN_PEERS=
MONGO_URL=
MONGO_QUERY=
MONGO_PORT=27017
MONGO_DB=gun
MONGO_COLLECTION=local

GoodServer

Clone the repository and install dependencies

git clone [e-mail]:GoodDollar/GoodServer.git
cd GoodServer
npm i

Copy .env.dev to .env, then append .env file with the following creds:

MONGO_DB_URI=mongodb://localhost:27017,<additional hostname/ip from mongod.conf>:27017/gooddollar?replicaSet=local
GUNDB_PEERS=http://localhost:8765/gun
GUNDB_PASS=password
ZOOM_SERVER_BASEURL=https://api.facetec.com/api/v3/biometrics
ZOOM_LICENSE_KEY=
ALCHEMY_API=
INFURA_API=
MAUTIC_BASIC_TOKEN=
MAUTIC_TOKEN=
MNEMONIC=
SECURE_KEY=
TWILIO_AUTH_ID=
TWILIO_AUTH_TOKEN=
TWILIO_VERIFY_ID=

You could take missing creds from the Heroku's good-server instance or ask your team leader for the complete .env file

GoodDAPP

Install and configure application the same way as described in the "DApp-only install" section of this document. To use local instances of the GoodServer and GunDB, edit the following env variables:

REACT_APP_SERVER_URL=http://localhost:3003
REACT_APP_GUN_PUBLIC_URL=http://localhost:8765/gun

Running

The most preferrable way to run the whole app (gun + server + dapp) locally is to use separate Terminal's tabs.

Gun

cd GoodGun
npx pm2 start --only gun-local
npx pm2 logs # enables logs output

Don't forget to unload Gun after your work is done:

npx pm2 stop all

GoodServer

cd GoodServer
npm run dev

GoodDAPP

cd GoodDAPP
npm run web

Mobile devices/emulators hints

There are issues when you want to run the app on iOS or Android with local server. It won't connect to the local GoodServer/GoodGUN instances.

The simplest way to solve this - to run the app with gooddev/goodqa server (see "DApp-only install" section of this document).

If you need the exactly local server, you have to use services to expose it to some public domain. Something like Serveo or its analogue. More detailed solution is explained at the end of this document.

Complete guide

Prerequisites

Additionally to the preparations listed at the beginning of this doc, you also have to:

Install truffle + ganache-cli

npm install -g truffle ganache-cli

Install python 2.7.*

Clone and install

Clone the repository and install dependencies

git clone https://github.com/GoodDollar/GoodBootstrap.git
cd GoodBootstrap
npm i

This will create a git folder for dapp, server and contracts projects in the ./packages folder

make sure master branch is checked out.

if not run: npm run master-submodules

Set environment variables

Environment .env files

Default environment variables are set up in .env.dev you can overwrite these variables by setting up .env which should include all required variables

Preferably copy .env.dev to .env in all projects. .env.dev contains reasonable defaults for using with pm2. Go over env.example to for more info.

.env.dev only works when using pm2, otherwise use .env

Update missing env

in folder packages/server edit .env.dev

MONGO_DB_URI=<your local mongo>

Start Project

#linux
npm start

This will start the local blockchain, will wait 60 seconds for contracts to finish compile and deploy and then start the server+dapp that will be linked (npm link) to use the local version of the contracts package (that's why we need to wait for them to be deployed)

Start dev env

Usually when developing you'll want to change the env variables of the dapp+server which isnt very friendly with pm2 so you might consider starting the project as follows instead of the above

#on linux
npx pm2 start --only good-blockchain,good-gun

#alternatively on windows
cd packages/gun
npm start

#alternatively on windows
cd ../packages/contracts
npm start

#wait until contracts have been deployed (npx pm2 logs)

cd packages/server
npm run dev:local

#maybe on a new shell
cd packages/dapp
npm run web:local

Using a different blockchain network

• contracts: add network in truffle-config.js and modify $NETWORK in .env

• dapp: add network in src/config/config.js and modify $NETWORK in .env

• server: add network in src/server/networks.js and modify $NETWORK in .env

Please note that both server and dapp must use the same blockchain network and the same @goodcontracts version.

If you are running a local blockchain make sure you start server+dapp after contracts finish deploying

GoodServer

Server side of the project is responsible to some actions that cannot be decentralized as creating a user, topping the wallet and sending confirmation emails.

Default environment variables are set up in .env.dev you can overload this variables by setting up .env which should include all required variables

DAPP Unit Testing

# Web
$ npm run test:web

# Update Snapshots
$ npm run test:web -- -u

# Web watch mode
$ npm run test:web-watch

# Coverage - web
$ npm run coverage

Mobile Development Environment

If you want to connect with a mobile you'd need to make sure your services run with SSL (since webcrypto requires ssl).

The easiest option is to use serveo.net by:

#If you use a local blockchain, change the .env variable
REACT_APP_WEB3_RPC=https://<yourchainsubdomain>.serveo.net
#Goodserver url
REACT_APP_SERVER_URL=https://<serversubdomain.serveo.net

#then run
ssh -R <dappsubdomain>:80:localhost:3000 -R <serversubdomain>:80:localhost:3003 -R <chainsubdomain>:80:localhost:9545 serveo.net
