@truffle/db

Truffle DB is a complete, flexible system for the querying and mutation of Truffle’s smart contract records. Following the data model available here, Truffle DB persists smart contract information that is typically found in a project's artifacts, and allows for querying this data using GraphQL.

Truffle artifacts are currently stored as JSON files in a project’s build/contracts/ directory. These documents are currently the canonical source of information about a project’s smart contracts. While useful, artifacts can be limited for certain advanced use cases.

For example, the artifacts format expects contracts with unique names. This means that currently a developer is unable to keep two contracts in their project that have the same name. Truffle DB solves this problem with a name record-keeping system that can keep track of multiple contracts in this situation.

Built With

Truffle DB is built with:

• TypeScript
• GraphQL
• Apollo
• PouchDB

Configuration to enable Truffle DB

Add the following to your truffle-config.js file in order to enable Truffle DB

db: {
  enabled: true
}

Note: Enabling Truffle DB does not affect artifacts, but will produce a new .db directory when you compile or migrate your project.

It will soon be possible to load and access Truffle DB data via truffle compile and truffle migrate. Stay tuned!

Usage

const { connect } = require("@truffle/db")
