missions-api

An event listener for contracts deployed on binance smart chain to store the events information in the database

Requirements

• Docker 20.10.6+
• Compose 3.3+
• Go 1.15+
• Postgresql 12.6

Running the service

For development purposes

1. Modify config.yaml file with your needs:

   • Provide a database url where the information will be stored in the form as provided here

       db:
          url: "postgresql://[userspec@][hostspec][/dbname][?paramspec]"

   • Provide contract address instead of 0x0..0

       contract:
          address: "0x0000000000000000000000000000000000000000"

   • Provide block number to start with

       blockchain_info:
                  from_block_num: 8325019

   • If you are using local blockchain (e.g Ganache), provide other endpoint

       rpc:
          endpoint: "http://127.0.0.1:8545" # or localhost

2. Open project using IDE (e.g GoLand from JetBrains), open IDE terminal, run

   go mod init
   go mod vendor

3. At bsc-checker-events/assets/main.go run two migration related scripts:

   //go:generate packr2 clean
   //go:generate packr2

4. Entry point is bsc-checker-events/main.go

5. Modify run configuration as follows:

   • KV_VIPER_FILE=config.yaml (environment variable)

6. Run service twice with the following command arguments:

   migrate up
   run service

For deployment purposes

1. Navigate to the cloned repository

2. Do the step 1 from development build, except modify config at configs/spaceship-staking.yaml, changing contract address and database url (for the contract deployed on the Binance Smart Chain leave the endpoint as it is

3. Build container image:

   docker compose build

4. Run using docker-compose

   docker-compose down -v
   docker-compose up -d

API

To change port, configure

listener:
  addr: :8888

where 8888 is a port to listen on.

Endpoints

/missions # get all missions
/missions/{mission-id} # get mission by it's id
/explorers/{explorer-address} # get missions joined by explorer address
