Ethlance V.2 (Newlance)

CircleCI

Ethlance Version 2 is Currently in Development and is subject to change before final release

Development

Prerequisites

Run make check to determine whether you are missing any prerequisites

Setup Backend

Backend development requires:

  • instance of a figwheel server build

  • an attached node server to the figwheel server

  • a solidity contract compiler (lein-solc)

  • an local IPFS daemon with properly configured CORS privileges (ipfs)

  • a test net (ganache-cli)

Quickstart Server

Terminal 1 (cljs repl):

make fig-dev-server

Terminal 2 (node server):

# Wait for fig-dev-server prompt: 'Prompt will show when Figwheel connects to your application'
make dev-server

Terminal 3 (testnet):

make testnet

Terminal 4 (truffle):

make deploy

Terminal 5 (ipfs):

make ipfs

Terminal 1 (server repl):

(start)
        ;; By default, this will deploy the smart contracts, generate users
        ;; and scenarios, and synchronize the results within the SQLite database.

(help)  ;; To review additional commands

Quickstart Browser

Terminal 1 (cljs repl):

make fig-dev-ui

Terminal 2 (LESS Compiler):

make build-css watch-css

Open Browser to http://localhost:6500

Initial Setup

Note: All instructions start in the root of the project directory

If this is a first time setup, or you accidentally ran make clean-all, you are required to re-install additional node dependencies with:

Tested with GCC 6 & GCC 7, does not appear to work with GCC 8

make deps

If you're having issues with your environment, you can run this command:

make clean-all deps

Additional Troubleshooting

  • Make sure you are using NodeJS LTS Version. (Latest LTS Version is v10.16.3 as of this posting)

  • GCC 8+ do not work with some of the district libraries. This might change in the future. Please use GCC Version 6, or GCC Version 7.

Figwheel Server and Node Server Instance

Note: All instructions start in the root of the project directory

Open two terminals. In the first terminal, type:

$ make fig-dev-server

After a short while, the build will prompt for a connection.

In the second terminal, type:

$ make dev-server

The the figwheel server should establish a connection with the node development server, and a CLJS repl should be available in the first terminal.

Testnet Server

Our local development environment requires a testnet in order to run smart contracts. Ethlance Development uses ganache-cli with a default configuration.

$ make testnet # Run in a separate terminal

IPFS Server

IPFS is an essential technology in ensuring that large blobs of data can be stored in a decentralized manner. After installing the ipfs commandline tool, you need to start up a daemon for development

ipfs daemon

Note: Might require additional configuration for CORS

ipfs config --json Gateway.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "GET", "POST", "OPTIONS"]'
ipfs config --json Gateway.HTTPHeaders.Access-Control-Allow-Origin '["*"]'
ipfs config --json Gateway.HTTPHeaders.Access-Control-Allow-Headers '["X-Requested-With"]'
ipfs config --json Gateway.Writable true

Smart Contract Deployment, User / Scenario Generation, Syncing

If all of the previous sections are completed, we can perform a smart contract deployment on the testnet through the fig-dev-server CLJS-REPL.

While in the Figwheel Server CLJS REPL, type:

(start) ;; Reloaded Lifecycle

You should see activity in the ganache-cli testnet server.

Deployment

Ethlance product can be prepared for deployment by running:

$ make build

This compiles everything and places it in the ./dist folder

After building, the production build can be run:

$ make run

Testing One-touch

To run all of the tests in a standalone test runner, you must first build the solidity contracts, run an instance of the testnet server, and an instance of the IPFS daemon. The test runner can be run via:

make clean deploy test

Contributing

Anyone is welcome to contribute to the ethlance project, here are some brief guidelines:

  • Make sure to squash your commits
  • Reference issue numbers in your pull request
  • Rebase your changes on upstream (git remote add upstream https://github.com/madvas/ethlance.git) master before pushing (git pull --rebase upstream master)
  • Make changes in a separate well-named branch in your forked repo like improve-readme
