Node js project to post to twitter when HRC20 token transactions exceeds a specific transaction value

  1. Go to https://dev.to/codesphere/using-the-twitter-api-with-nodejs-4p3c for tutorial if you want to follow it.

  2. Go to https://developer.twitter.com/en/apply-for-access and create a developer account. This should be from the account where you want to tweet from.

  3. Request elevated rights on your account.

  4. Create a new project and also elevate the rights on the oAuth v1 API to read and write. You need to give a callback URL, I simply gave my static website as I won't be using oAuth in that way.

  5. Generate access token and secret.

  6. Extract zip file and run "npm install" from the root directory of the unzipped folder. The following dependencies will be installed:

  • "node-fetch": "^2.6.7"
  • "twitter-api-v2": "^1.12.0"

  1. Replace the values in the config.js for the following fields:

    • appKey - Retrieved from twitter developer account
    • appSecret - Retrieved from twitter developer account
    • accessToken - Retrieved from twitter developer account
    • accessSecret - Retrieved from twitter developer account
    • hrc20Name - Update HRC20's Token Symbol. You can retrieve token information at https://explorer.htmlcoin.com/tokens/search. Example - Codex
    • hrc20Symbol - Update HRC20's Token Symbol. You can retrieve token information at https://explorer.htmlcoin.com/tokens/search. Example - CDEX
    • messageIcons - Add icons that will be randomized for each tweet. Add more from https://getemoji.com/ .
    • minimumTxnAmount - Update minimum transaction value to trigger alert.

  2. Run node hrc20TokenGetLatestTxns.js from the root directory of the unzipped folder.
