Swarm Comment System Library

A library for writing and reading comments from the Swarm network.

Installation

To install the library, use npm or yarn:

npm i @solarpunkltd/comment-system

Usage

Writing a Comment

To write a comment to the Swarm network, use the writeComment or writeCommentToIndex functions:

import { writeComment, writeCommentToIndex } from "@solarpunkltd/comment-system";

const comment = {
  message: {
    text: "This is a comment",
    messageId: "unique-message-id",
  },
  timestamp: Date.now(),
  username: "user123",
};

const options = {
  stamp: "your-stamp-id",
  signer: "your-private-key",
  beeApiUrl: "https://your-bee-node-url",
  approvedFeedAddress: "your-feed-address",
};

writeComment(comment, options)
  .then(result => {
    console.log("Comment written:", result);
  })
  .catch(error => {
    console.error("Error writing comment:", error);
  });

const index = 123;
writeCommentToIndex(comment, index, options)
  .then(result => {
    console.log(`Comment written to index ${index}:`, result);
  })
  .catch(error => {
    console.error(`Error writing comment to index ${index}`, error);
  });

Function writeComment writes a comment to the next feed index. It needs to look up the latest feed index before writing. Function writeCommentToIndex writes a comment to the desired specific index.

Reading Comments

To read comments from the Swarm network, use the readComments, readCommentsInRange or readSingleComment functions:

import { readComments, readCommentsInRange, readSingleComment } from "swarm-comment-system";

const options = {
  identifier: "your-identifier",
  beeApiUrl: "https://your-bee-node-url",
  approvedFeedAddress: "your-feed-address",
};

readComments(options)
  .then(comments => {
    console.log("Comments read:", comments);
  })
  .catch(error => {
    console.error("Error reading comments:", error);
  });

const start = 0;
const end = 10;
readCommentsInRange(start,end,options)
  .then(comments => {
    console.log(`Comments read from range ${start} to ${end}:`, comments);
  })
  .catch(error => {
    console.error(`Error reading comments from range ${start} to ${end}:`, error);
  });

const index = 3;
readSingleComment(index, options)
  .then(comments => {
    console.log(`Comment read at index ${index}:`, comments);
  })
  .catch(error => {
    console.error(`Error reading comment at index ${index}:`, error);
  });

Function readComments reads comments from index 0 until the latest found index, in succession. Function readCommentsInRange reads comments from the desired index range, parlelly. Function readSingleComment reads one single comment at the given index, if not provided it looks up and reads the latest comment.

Limitations

Writing to a feed index that is already taken does not result in an error, therefore reading back the comment at the expected index is necessary as a verification of success.
