d-reader-backend

NestJS backend for dReader dapp on Solana

⚠️ Prerequisites

Note generate a new Helius API key via Helius Dashboard

To test webhooks we recommend creating a reverse proxy to your local machine on which your localhost webserver is running. We suggest using ngrok, which you can set up by following these instructions

Note ask DevOps engineer to generate new IAM user credentials for you

⚙️ Setup

Warning make sure your node version matches the one specified in .nvmrc

Install dependencies and copy the .env.example content into .env:

yarn add & cp .env.example .env

Next run the command for generating env variables and replace placeholder values from .env as per instructions in the terminal. Fill in any remaining variables by following notes from the .env section:

yarn generate-env

Then run migrations and seed the database:

yarn migrate:dev

yarn seed

Once steps above completed, run the following command to start the project in watch mode:

yarn start:dev

Open http://localhost:3005 with your browser to see the result. API documentation is available on the /api route

🫡 Commands

For airdropping Sol to a specified wallet use the following command

yarn airdrop-sol

To authorize your treasury wallet (sign a message and generate a JWT token):

yarn authorize-wallet

🌱 .env

• JWT_ACCESS_SECRET and JWT_REFRESH_SECRET are randomly generated 42 char strings
• SOLANA_CLUSTER can be either mainnet-beta, testnet or devnet. Rule of thumb is to use devnet on localhost development, and mainnet-beta for production applications
• AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY are necessary for app to work as intended since app relies on AWS S3 for file storage. These credentials can be obtained upon IAM user creation (contact sysadmin to create IAM user for you)
• AWS_BUCKET_NAME should be delivered by sysadmin alongside AWS credentials
• TREASURY_PRIVATE_KEY is the AES encrypted private key of a wallet used as a Treasury. All royalties will be collected there and all our payments will be done with it.
• TREASURY_SECRET is the secret key used for AES encryption/decryption of the Treasury wallet's private key, preferably 64 byte long
• MAIL_SERVICE and other mail related variables are unnecessary unless working on email-related features. Make sure to download NodemailerApp for local development. For production setup follow the nodemailer-gmail-smtp guide
• HELIUS_API_KEY can be obtained via Helius Dashboard
• DISCORD_WEBHOOK_URL can be obtained on discord by creating a channel and going to "settings -> integrations"
