How specify dependency in my plugin

[Doppy]

I need to use "SparkPost" in my plugin and I need to define the dependency in my plugin.json to be installed automatically. Anyone can help me?

@Doppy add it to your plugins package.json

"dependencies": {
    "sparkpost": "1.3.6"
 }

Alternatively, just install it with the --save flag and it will pin the current version in your package.json

npm install --save sparkpost
