Ethereum blockchain orchestration, testing, CLI, and Dapp scaffolding.

install

easiest: use docker (it handles the environment and RPC node for you):

docker run -ti --rm --name clevis -p 3000:3000 -p 8545:8545 \
  -v ~/your-dapp-directory:/dapp austingriffith/clevis:latest

OR install/link for the source:

git clone https://github.com/austintgriffith/clevis.git
cd clevis
npm install
sudo npm link

OR try an npm install:

sudo npm install --unsafe-perm -g clevis@latest

If you aren't using docker make sure you install ganache-cli and mocha:

npm install -g ganache-cli
npm install -g mocha

docker options

attach to already running clevis container

external RPC

docker run -ti --rm --name clevis --env network="http://10.0.0.107:8545" \
  -p 3000:3000 -p 8545:8545 -v ~/your-dapp-directory:/dapp austingriffith/clevis

Automatic Rinkeby Geth Node

docker run -ti --rm --name clevis --env network="rinkeby" \
  -p 3000:3000 -p 8545:8545 -v ~/your-dapp-directory:/dapp austingriffith/clevis

Automatic Ropsten Geth Node

docker run -ti --rm --name clevis --env network="ropsten" \
  -p 3000:3000 -p 8545:8545 -v ~/your-dapp-directory:/dapp austingriffith/clevis

Automatic Mainnet Geth Node

docker run -ti --rm --name clevis --env network="mainnet." \
  -p 3000:3000 -p 8545:8545 -v ~/your-dapp-directory:/dapp austingriffith/clevis

Docker build from Clevis Repo

git clone https://github.com/austintgriffith/clevis.git
cd clevis
docker build ./docker -t clevis
docker run -ti --rm --name clevis -p 3000:3000 -p 8545:8545 -v ~/your-dapp-directory:/dapp clevis

Using Infura

If you want to use Infura to deploy, you need to make the following changes:

In your clevis.json config file, change:

USE_INFURA: true

Create a .env file and add your private key under mnemonic:

mnemonic=32h42hj34mysuperprivakeyasdasd2h34hjk234

troubleshooting

Right now the web3 dependencies are not very well supported and installs can fail on certain machines.

I would recommend using Docker and the container model because it handles the environment and geth node for you.

WARNING if you get this error: gyp ERR! stack Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/clevis/node_modules/scrypt/build'

rm -rf .node-gyp
sudo npm install --unsafe-perm -g clevis@latest

Sometimes you might get a "Cannot find module 'web3' error"

clevis test version
(node:32368) UnhandledPromiseRejectionWarning: Error: Cannot find module 'web3'

(node:32368) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

The fix for this is to go to wherever you have clevis cloned and run an npm link again: (and maybe an npm i)

cd ~/clevis
npm link

Another error I run into from time to time due to Create React App with 'npm run build':

.../node_modules/mini-css-extract-plugin/dist/index.js:20
  util: { createHash }
          ^

TypeError: Cannot destructure property `createHash` of 'undefined' or 'null'.

To fix it you just need to install webpack locally in your project with:

npm install --save webpack

---

Another error I've hit is this one:

There might be a problem with the project dependency tree.
It is likely not a bug in Create React App, but something you need to fix locally.

The react-scripts package provided by Create React App requires a dependency:

  "babel-eslint": "9.0.0"

Don't try to install it manually: your package manager does it automatically.
However, a different version of babel-eslint was detected higher up in the tree:

to fix this, add a .env file with "SKIP_PREFLIGHT_CHECK=true" in it:

echo "SKIP_PREFLIGHT_CHECK=true" >> .env
