Local Development

Origin has two development setups. One is the “light” version and consists of only our DApp and a local IPFS server and blockchain. It is intended to be easy to get started with but lacks some of the components of our stack making some of the DApp functionality unavailable.

The more full featured development environment uses Docker Compose to orchestrate several containers and provides access to the full suite of Origin features, include messaging, browser notifications, and attestation services.

About the Origin repository

Origin uses a monorepo setup that is managed by lerna. The --hoist flag of lerna is used to pull common dependencies to the root of the monorepo on installation.

Using NPM & Lerna

  1. Check out the repository from GitHub and make sure you have installed all the necessary dependencies:
git clone https://github.com/OriginProtocol/origin
cd origin && npm install
  1. Configure the DApp with default environment variables:
cp origin-dapp/dev.env origin-dapp/.env
  1. You can then start a light development environment by executing:
npm start
  1. You will then need to connect to your locally running blockchain in MetaMask. Follow these steps:
candy maple cake sugar pudding cream honey rich smooth crumble sweet treat

This is the default seed phrase used by Truffle for development.

⚠️ Be careful not to mix up your test wallet with your real one on the Main Network.

Troubleshooting

Using Docker Compose

The Origin Docker Compose configuration runs the following packages:

- origin-bridge on http://localhost:5000
- origin-dapp on http://localhost:3000
- origin-discovery (event-listener)
- origin-discovery (apollo server on http://localhost:4000)
- origin-ipfs-proxy on http://localhost:9999
- origin-messaging on http://localhost:9012
- origin-notifications on http://localhost:3456)
- origin-js (ipfs server)
- origin-js (ethereum blockchain using ganache on http://localhost:8545)
- postgresql
- elasticsearch on http://localhost:9200

System Requirements

Getting Started

⚠️ If you have previously used docker-compose with Origin, please ensure you clear out old containers by stopping any running containers and executing docker system prune --volumes --all before completing these steps.

  1. Clone the repository:

git clone https://github.com/OriginProtocol/origin cd origin

  1. Optional: Pick which version of the code you want to run. The latest code is on the master branch (which is checked out by default), while the code currently deployed in production is on the stable branch. For example, to use the stable branch, run:
    git checkout --track origin/stable
    
  2. From the root of the repository run docker-compose up. The first time this command runs it will take some time to complete due to the initial building of the containers.

Please note this can take some time. If you see an error in the logs please raise an issue. When the containers are running you can access the DApp at http://localhost:3000.

Usage and commands

Please refer to the docker-compose documentation for usage. Some commands that may be useful are included below.

Start and stop the environment:

docker-compose up
docker-compose down

Spawn a shell (command line) in a container:

docker exec -ti <container_name> /bin/bash
docker exec -ti origin-dapp /bin/bash

Follow log output for all containers:

docker-compose logs -f

Restart a container. In a new terminal window:

docker-compose restart <container_name>

Rebuild containers (takes some time), in case you update dependencies (including npm). In a new terminal window:

docker-compose build --no-cache origin

Troubleshooting

Elasticsearch fails to start with virtual memory error

The development stack includes an Elasticsearch container which may require an increase in the mmap counts for your OS. On Linux this can be achieved by running:

sysctl -w vm.max_map_count=262144

For more information, see this link.

Docker Container exited with code 137

If a container is failing with code 137 it could be that it has encountered Out Of Memory error. To fix this dedicate more memory to Docker see this link.

Port errors

The environment requires a number of ports to be free on your machine (3000, 5000, 5002, 8080, 8081 and 8545). If one of these ports isn’t available spinning up the development environment may fail.

Metamask errors

Sometimes Metamask gets confused on private networks. If you see errors generated by Metamask in your console while developing then clicking SettingsReset Account in Metamask should resolve the issue.
