Head to https://www.originprotocol.com/developers to learn more about what we're building and how to get involved.
origin-js is a library of javascript code and Ethereum smart contracts which allow anyone to create decentralized marketplaces, including for fractional usage. It is an open source project created by Origin Protocol.
origin-js is showcased in our Demo DApp currently running on the Rinkeby testnet.
npm install origin --save
or
yarn add origin
A browser-compatible plain javascript file origin.js is available in the Releases section. A hosted version can be directly included in your html as:
<script src="https://code.originprotocol.com/origin-js/origin-v0.6.1.js"></script>npm build will generate this file and save it to dist/origin.js.
git clone https://github.com/OriginProtocol/origin-js.git && cd origin-js
If you would like to submit pull requests, you should instead fork this repo and then clone your fork. Note pull requests should always be made to the develop branch, which always has the latest commits.
npm run install:dev
install:dev is shortcut for npm install && npm link. Linking means that changes to origin-js code are immediately available to local DApps without an npm install.
npm start
Code changes will trigger a live rebuild.
To interact with your local origin-js and local blockahin, see the instructions in our Demo DApp.
Our full test suite can be run with:
npm run test
Note: you should not have the server running at this time, as these tests start their own local blockchain instance.
Our Solidity tests (which use Truffle) are located at contracts/test.
npm run test:contracts
Note: you should not have the server running at this time, as these tests start their own local blockchain instance.
A subset of our tests can be run from the browser. These tests are automatically served at http://localhost:8081 when you run npm start. These tests are automatically rerun when source or test code is changed.
Run a subset of these tests using the grep query string parameter, for example: http://localhost:8081/?grep=IpfsService
If you have Python 3 installed, you may see this error when installing dependencies:
gyp ERR! stack Error: Python executable "/Users/aiham/.pyenv/shims/python" is v3.6.4, which is not supported by gyp.
Resolve this by configuring npm to use Python 2 (where python2.7 is a binary accessible from your $PATH):
npm config set python python2.7
