README

Chainlink Core is the API backend that Chainlink client contracts on Ethereum make requests to. The backend utilizes Solidity contract ABIs to generate types for interacting with Ethereum contracts.

Features

• Headless API implementation
• CLI tool providing conveniance commands for node configuration, administration, and CRUD object operations (e.g. Jobs, Runs, and even the VRF)

Installation

See the root README for instructions on how to build the full Chainlink node.

Directory Structure

This directory contains the majority of the code for the backend of Chainlink.

Static assets are pulled in using Go's embed package and included in the final binary.

Common Commands

Install:

By default go install will install this directory under the name core. You can instead, build it, and place it in your path as chainlink:

go build -o $GOPATH/bin/chainlink .

Test:

# A higher parallel number can speed up tests at the expense of more RAM.
go test -p 1 ./...

This excludes more extensive integration tests which require a bit more setup, head over to [./integration-tests] (../integration-tests/README.md) for more details on running those.

The golang testsuite is almost entirely parallelizable, and so running the default go test ./... will commonly peg your processor. Limit parallelization with the -p 2 or whatever best fits your computer: go test -p 4 ./....
