How to start latest version?

[doopie-art]

Hi,

I was running an old version of the bot that was initiated by calling 'npm start'. I've updated for the OS contract update, but it's not clear to me how to start the bot now.

Thanks,
D

You can now initialize a new npm project to use the sales bot.

1. create a project folder, and navigate to it
2. run npm init -y
3. add "type": "module" to package.json
4. run npm install enft dotenv

Copy the following example file as index.js.

Run node index.js to start the script. (make sure you are using node version >= 18)

Please note that you will need to modify some of the fields. The comments in the example/js/onItemSold.js file will guide you through the process.

If you're not familiar with Node.js, I suggest you learn by either searching on Google or asking ChatGPT for help.

Thanks for the reply.

I have setup as you described, however now I'm getting error that infura.apiKey is not allowed to be empty.
I have configured an Alchemy key in .env from my previous build and I was under the impression only one is required?

// Set up the Auth with the provider api keys (at least one is required)
const auth = new Auth({
    alchemy: {
        apiKey: process.env.ALCHEMY_API_KEY
    },
    infura: {
        apiKey: process.env.INFURA_API_KEY,
        apiKeySecret: process.env.INFURA_API_KEY_SECRET
    }
});

error:

Error: missing argument: "infura.apiKey" is not allowed to be empty (location="[Auth.constructor]", code=MISSING_ARGUMENT, version=1.1.1)

If you only use Alchemy then just delete the infura key and value as below:

// Set up the Auth with the provider api keys (at least one is required)
const auth = new Auth({
    alchemy: {
        apiKey: process.env.ALCHEMY_API_KEY
    }
});

Great, thank you!

I commented out the Infura section, also the twitter section as I don't use this either.
The bot runs now when I configure a single contract address in the .env, however when I try to use multiple I get an invalid param error. How can multiple addresses be monitored?

Thanks again,
D

The startup script also seems to say Discord is disabled even though I have it set to 1 and provide a webhook?

[kenryu42]

Use for loop for multiple listeners:

const contractAddresses = ['0x..', '0x...'];

for (let i = 0; i < contractAddresses.length; i++) {
    enft.onItemSold({
        contractAddress: contractAddresses[i],
	etherscanApiKey: process.env.ETHERSCAN_API_KEY,
	discordWebhook: process.env.DISCORD_WEBHOOK
    })
}

No need set to 1 in .env anymore.

Ensure that the name of your Discord webhook variable in your .env file matches the name used in your script.

For example, your .env must be DISCORD_WEBHOOK=XXXX for above script to work.

Great! Thanks, it looks I'm up and running again now! Much appreciated
