Just as you would any environment variable from node

const tableName = process.env.TABLE_NAME;

require('process') isn't necessary. Just process.env.TABLE_NAME will work as process.env is set globally in node. – Usman Mutawakil Jan 30 '18 at 03:59

I am just adding to the original answer to clarify the scope.To fetch any environment variable whether is defined by API or manually, you can use process.env.VAR_NAME

E.g.

You can fetch the above using

let env = process.env.ENV_NAME

To read about it , you can refer the doc at AWS Doc
