Service of the Streamr Network that listens to events emitted by the Streamr Marketplace smart contract and informs Core API of changes to products.
For redundancy, run multiple instances in parallel attached to different Ethereum nodes.
Project uses npm for package management.
- Start off by selecting correct Node and Npm version
nvm use - Install required dependencies with
make node_modules - To run tests
make test - To run ethereum-watcher locally
make run - To build local Docker image, start Streamr Docker stack and to see logs run
make docker-build start log
In most cases, you will want to run this service as a pre-built Docker image. See https://github.com/streamr-dev/streamr-docker-dev for more information on how to run the Streamr stack.
If you are developing this service in particular, or are otherwise inclined, you can run this service with make run.
The project is automatically tested and built using GitHub Actions. If and when all tests pass, a Docker image is built and pushed to DockerHub by GitHub Actions.
Runs on integrations.streamr.network.
