This app is here to allow for people to accept online payments via Stripe.
Vue has it's own env and so does go. That's not that fun. Make sure that you put your stripe testing key in both .env and ./payment-vue/.env. When the vue app gets built for prod, make sure you reference the stripe key from the Go env file. To do this, make sure you have a file named .env.production in the vue app folder, and that the key VUE_APP_STRIPE_PUB_KEY is set to this: {{ .StripePublicKey }}
If you want to run the node dev server, make sure you visit the app at the sub folder address. On my machine, that's this: http://localhost:8080/static/
