Airnode is a fully-serverless oracle node that is designed specifically for API providers to operate their own oracles. See the docs for deployment and usage instructions.

Structure

This is a monorepo managed using Lerna. It houses the following packages:

adapter: The module that makes an API call, processes the response and returns a single value

admin: A package/CLI tool to interact with the Airnode contracts across chains

airnode-abi: Encoding and decoding utilities for Airnode according to the Airnode ABI specifications

deployer: Tools to automate Airnode deployment

examples: A public list of examples showcasing the features of Airnode

node: Airnode itself

ois: Types for Oracle Integration Specification (OIS)

operation: Development and testing utilities for the core parts of Airnode

protocol: Contracts that implement Airnode RRP (request–response protocol)

validator: A package that can be used to validate and convert airnode specification files

Instructions

To install dependencies, run this at the repository root:

yarn run bootstrap

To build all the packages, run this at the repository root:

yarn run build

Airnode packages are cross platform, available as npm packages or docker containers. You should also be able to clone, build and use the packages on any platform. However we do not guarantee that the development only features (e.g. test or examples) will work out of the box.

We heavily recommend using UNIX based systems for development. If you are using Windows, consider WSL.

Changelog

We use changesets to manage the changelog for us. What that means for contributors is that you need to add a changeset by running yarn changeset which contains what packages should be bumped, their associated semver bump types and some markdown which will be inserted into changelogs.

Tip: Add export EDITOR="code --wait" to .bashrc to make it possible to write changelog description in VS Code (you can adapt the configuration for other editor similarly).
