Checklist 📝

Make sure you follow all these steps when launching this API:

1. Upload this project to a linux virtual machine on the cloud (digital ocean, amazon web services etc..)
2. Replace your contract ABI ./Contract.json
3. Replace your un revealed image on ./unrevealed/image.png
4. Set the variables on the top of scripts/start.js, keep the IS_REVEALED variable set to false to start the server with unrevealed mode
5. Start the server with npm start
6. Put all your images and metadata on ./images/ and ./metadata/ respectively

• Consider using FTP or scp, for example: scp -r user@ssh.example.com:/path/to/remote/source /path/to/local/destination

8. run npm run shuffle
9. run npm run remove_none_traits if needed
10. Upload your images, choose between CGS or IPFS

• IPFS
  • Run npm run upload_images_ipfs
• Google Cloud Services
  • Put your gcs.json keyfile on this project directory
  • Run npm run upload_images_gcs
  • Install the google cloud console and run this to open the files in the browser instead of downloading them by downloading the Google Cloud SDK and running this: gsutil -m setmeta -h "Content-Type: image/png" -h "Content-Disposition: inline;" gs://YOURBUCKETNAME/*. Remember to set YOURBUCKETNAME.

11. Once you want to reveal the Images and Metadata set the IS_REVEALED to true on scripts/start.js, stop and restart the server
