Node JS Client to contribute ping times to the Validators.app Ping Thing.
git clone https://github.com/Block-Logic/ping-thing-client.git
cd ping-thing-client/
Try yarn install. If that doesn't work, use:
yarn add @solana/web3.js
yarn add dotenv
yarn add xhr2
I use .env to hold sensitive data that I don't want to appear in the GitHub repo. Copy .env.sample to .env and replace the values inside the file with your data. The .env file needs your private wallet keypair in base58 format. There is a simple Ruby script that will convert a keypair.json file into base58. See keypair_to_base58.rb
Before you can post pings to validators.app, you will need an API key. You can sign up at https://www.validators.app/users/sign_up and grab a free API key from your dashboard. Note: Your login handle will be displayed on the public Ping Thing page.
After retrieving your API key, copy & paste it into the VA_API_KEY attribute of your .env file.
In the .env file, try VERBOSE_LOG=true to see log output the first time you run the script. After saving your .env file, try running the script with node ping-thing-client.mjs and watch the output. I use VERBOSE_LOG=false in production to minimize log noise.
You can start the script & push it to the background with node ping-thing-client.mjs >> ping-thing.log 2>&1 &.
Look for an example service file in this repo soon.
If you are running the Ping Thing client on your validator node, you need to enable private RPC for access from your localhost. You also need to enable --enable-rpc-transaction-history to get the TX slot after confirmation.
