bitcoin-message.com — Leave your mark on cryptocurrency world! Save your message in Bitcoin blockchain. Forever! 🚀

With Bitcoin you can not only pay for things, but also store data in its blockchain which will be saved forever on thousand of blockchain-nodes across the world. So why not use it for something fun? 😉

Dev things I wanted to achieve in that project:

• try to use blockchain technologies for something fun
• use React for frontend (despite the fact that I prefer Angular 2/4+ and @ngrx)
• try Firebase for backend (and some frontend parts)
• try MobX for state management (as I found it looks really cool OOP-wise, near the same as services in Angular+RxJS)
• write serverless app (I mean: with backend, but without classic server)
• write beautiful backend implementation
• write beautiful frontend implementation (of course!)
• try to use async/await more widely

Prerequisites

Node 6+

Install

cd ./functions

yarn

cd ../

yarn

Run locally

You need to set next Firebase Environment Variables:

firebase functions:config:set blockchain.network="btc or tbtc or bch or tbch"

firebase functions:config:set blockchain.wallet_wif="your wallet WIF here"

firebase functions:config:set blockchain.fee_satoshis_per_byte=20

firebase functions:config:set donations.imap_user="your email"

firebase functions:config:set donations.imap_password="email password"

firebase functions:config:set donations.imap_host="IMAP of mail provider"

firebase functions:config:set donations.imap_mailbox_name="mailbox name if different from INBOX"

firebase functions:config:set donations.min_donation_amount=1.20

firebase functions:config:set donations.min_donation_currency="USD"

Then export it to .runtimeconfig.json for it can be used locally:

firebase functions:config:get > ./functions/.runtimeconfig.json

Then execute yarn server
