publish-pinata.js

/*
  This library will pin the app to Pinata. It expects a CID
  as input, which is the output of publish-filecoin.js.

  Filecoin should be though of as cold-storage for data. It's very slow to
  retrieve. Pinata can be though of as RAM. It keeps content at the ready and
  fast to deliver. They are complimentary services.

  In order to run this script, you must obtain an API key from pinata.cloud.
  That key should be saved to an environment variable named PINATA_JWT.
