Head to https://www.originprotocol.com/developers to learn more about what we're building and how to get involved.
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
--hoist flag of
lerna is used to pull common dependencies to the root of the monorepo on installation.
Using NPM & Lerna
- 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
- Configure the DApp with default environment variables:
cp origin-dapp/dev.env origin-dapp/.env
- You can then start a light development environment by executing:
- You will then need to connect to your locally running blockchain in MetaMask. Follow these steps:
Log out of MetaMask.
Restore from seed phrase
Enter the following seed phrase (Mnemonic):
candy maple cake sugar pudding cream honey rich smooth crumble sweet treat
This is the default seed phrase used by Truffle for development.
Click where it says "Ethereum Main Network" and select "Localhost 8545". Click the back arrow to return to your account.
You should see your first test account now has 100 ETH and the address
0x627306090abaB3A6e1400e9345bC60c78a8BEf57. Additional generated accounts will also have this amount.
- If IPFS fails to start with error "UnhandledPromiseRejectionWarning: Error: Lock file is already being hold", clean up the IPFS local data:
rm -rf ~/.jsipfs/
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
- Docker version 18 or greater:
- Docker Compose For Mac and Windows docker-compose should be part of desktop Docker installs:
- Unix-based system (OSX or Linux) needed to run the bash scripts
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.
- Clone the repository:
git clone https://github.com/OriginProtocol/origin
- 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
- 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
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
Configure environment variables in
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.
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.
Sometimes Metamask gets confused on private networks. If you see errors generated by Metamask in your console while developing then clicking
Reset Account in Metamask should resolve the issue.
