Initial recipe borrowed from nft-mix.
This won't run out of the box. The contracts must be compiled first:
$ brownie compile
The test run requires WEB3_INFURA_PROJECT_ID and PRIVATE_KEY env vars to execute.
Make a copy of the .env-template file as .env:
$ cp .env-template .env
Store your credentials in the .env file:
# .env
export WEB3_INFURA_PROJECT_ID="your project's ID string"
export PRIVATE_KEY="your wallet's private key (don't let anyone else see this)"
The brownie-config.yaml file includes an entry that looks for the .env file for credentials. If it doesn't happen automatically for some reason, source the .env file manually:
$ source .env
Once properly set-up, run main.py to test it out:
$ ./main.py

I've pinned a couple of different metadata files to be tested out:
- https://ipfs.io/ipfs/QmPwpUKU1KAxbuTCNBCLfE6N4EPWvyY7g2oBCjfLvtHvof?filename=picture.json (this is already the default)
- https://ipfs.io/ipfs/QmPhJ3LYLc7u3AGzbNEvPaa9TWAVuPkUtv7GCNmoRjUVgJ?filename=tree.json (an image of a binary tree)
Originally, this subsection contained instructions on how to "ignore" changes to the .env file, referenced from here. Unfortunately, this gets in the way of checking out different branches.
The recommended way as per Git's official documentation (link) is to just not use that feature for untracking config files.
Perform the following actions only if you've followed the instruction that was listed here before.
Undo the --skip-worktree flag:
$ git update-index --no-skip-worktree .env
Make a backup of the exiting .env file if you already have credentials stored there:
$ cp .env .env-bak
Pull from the repo:
$ git pull
That should've removed your local .env file.
Restore your credentials if you had it backed up:
$ mv .env-bak .env
See docs/README.md.
