SEND TRANSACTION WORKER

ABOUT

This worker will build a queue based on the routing key and type of message exchange to consume the message sent from Send Transactions controller.

After consuming the message, sign the transactions (using the vault key mentioned in the message) and send the transactions to Tezos block chain. Then it updates the corresponding job status to PUBLISHED and updates the operation hash (which is retrieved after sending the transactions).

Before running

Check if postgres database, rabbitMq and vault server are running. If not, you could start the services by using docker-compose.

docker-compose up -d postgres rabbitmq vault

Run with docker

docker-compose up send-transactions-worker

Run locally

Install dependencies and build the project

NOTES: This step could be skipped if it already ran.

npm i
npm run build

Install bunyan and nodemon

NOTES: This is optional. Bunyan helps to format the logs, so it is easier to read and nodemon helps auto recompile the code while you are in dev mode.

npm i -g bunyan nodemon

Run the project

npm run send-transactions-worker | bunyan

Run in dev mode

npm run send-transactions-worker:dev | bunyan
