# Grano DID Resolver

Grano DID Resolver is a program that returns values according to the [DID specification](https://www.w3.org/TR/did-core/) defined by the [W3C](https://www.w3.org/). It depends on [Sequelize](https://github.com/sequelize/sequelize) and all values refer to the off-chain database.

## How to Use

0. Create Mariadb and export data from [grano-did-contract](https://github.com/intellltech/grano-did-contract) using [grano-did-exporter](https://github.com/intellltech/grano-did-exporter)

1. Set DB configuration in `.env`

```env

DATABASE=grano

USERNAME=root

PASSWORD=password

DIALECT=mariadb

HOST=localhost

PORT=3306

```

2. Call Resolver

```index.js

const { Resolver } = require('did-resolver')

const { getResolver, DatabaseClient } = require('@intellltech/grano-did-resolver')

const main = async () => {

  const dbClient = new DatabaseClient()

  const granoDidResolver = getResolver(dbClient)

  const didResolver = new Resolver(granoDidResolver)

  const didDocument = await didResolver.resolve('did:grn:grano14fsulwpdj9wmjchsjzuze0k37qvw7n7am3reev', {})

  console.dir(didDocument, { depth: 3 })

}

main()

```

## Sample Response
