warning

Notice: You should install the pnpm package manager globally on your machine by using the npm package manager. You can install pnpm by running the following command: npm install -g pnpm@8.14.1. Using Corepack to install pnpm that will have some conflicts with the project dependencies that are using yarn package manager to install and build.

This project has been tested and optimized for Node.js version v20.12.2 and pnpm version 8.14.1. Please note that using a Node.js version later than v20.12.2 may result incorrect functionality and potential bugs. It is strongly recommended to use these specific versions for running and testing the project. Deviating from these versions may result in unforeseen compatibility issues or unexpected behavior.

Create a new project

Let's start by creating a new project

Install Veramo packages

The VCkit is built on top of the Veramo agent framework. The VCkit is a set of Veramo plugins that are configured to work together to provide a complete VC issuance and verification capability. That's why we need to install all the veramo core plugins first. To do it, run this command.

npm install @veramo/core @veramo/credential-w3c @veramo/credential-ld @veramo/did-resolver @veramo/did-manager @veramo/key-manager @veramo/did-provider-key @veramo/did-provider-pkh @veramo/did-provider-jwk @veramo/did-provider-ethr @veramo/did-provider-web @veramo/kms-local did-resolver @veramo/kms-web3 @veramo/data-store

Install other packages

Install some custom resolver by running this command.

npm install did-resolver ethr-did-resolver web-did-resolver

We also need to install sqlite3 with typeorm to store some data.

npm install sqlite3 typeorm
