Custom Plugin

This is a basic guide to getting started creating Veramo plugins. More in-depth tutorials to follow.

Start by using the veramo-plugin-template repo on Github. Click the Use this template button to copy the repo to your account. Clone the repo locally and rename the package name in package.json.

From the plugin directory:

yarn
yarn build
yarn generate-plugin-schema

Run the plugin template

Before customizing your plugin, ensure the project run correctly:

yarn start

In the logs you will be presented development URLS. You should have access to the Open API documentation of this agent.

Verify

To make sure your plugin is working correctly, let's create a new DID using its API:

note

You will need the API key which you can get from the agent.yml file.

Replace the NGROK_URL and API_KEY with your own and run:

curl -X POST "https://<NGROK_URL>/agent/idManagerCreateId" -H "accept: application/json; charset=utf-8" -H "Authorization: Bearer <APIKEY>" -H "Content-Type: application/json" -d "{}"

A new identifier should be printed in your console.

Customization

  1. Rename instances of MyAgentPlugin with your plugin name
  2. Define your plugin interfaces in IMyAgentPlugin.ts
  3. Extend your plugin context by importing other types from Veramo for example if you want to issue credentials from your plugin, import the ICredentialIssuer type.
  4. Replace sample arguments with your own
  5. Every time you update the types of your plugin, make sure you run:
yarn generate-plugin-schema
  1. The file my-agent-plugin.ts holds the implementation of your agent. It uses the interfaces defined in the src/types folder to define each method implementation. Again, review all the JSDOCS and add your plugin implementation.
