Graph Modules by Distributed Lab

This repository contains utility modules for implementing subgraphs for The Graph protocol. The modules can be imported and used to help develop extended subgraphs logic for numerous tasks.

The project is in the early stage of development and many new modules will be added soon. Here is what is available right now:

• array-helper module to ease work with arrays
• hash-table module to bound two arrays (like key-value struct) efficiently
• history-searcher module to search previous history entity with id pattern idBase + blockNumber
• type-utils module to easily determine if a given value is an instance of ByteArray, Bytes, or Address

Overview

Installation

$ npm install @solarity/graph-lib

The latest stable version is always in the master branch.
