INJECTION WORKER

ABOUT

This worker will consume the messages from the Injection Queue, which contains the messages sent from Injection controller.

After consuming the message, pre-apply the transactions and inject the transactions to Tezos block chain. Then it updates the corresponding job status to PUBLISHED and updates the operation hash (which is retrieved after injecting 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 injection-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 formatting 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 injection-worker | bunyan

Run in dev mode

npm run injection-worker:dev | bunyan
