The Commit Graph package is a React component suite designed to visualize commit graphs in an interactive and informative way. It showcases commit history within a repository with support for infinite scroll loading.

CommitGraph is utilized by platforms like DoltHub to visualize database commit log histories.

• Interactive Commit Graph Visualization: Render commit history as an interactive graph, offering a clear and detailed view of repository activities.
• Infinite Scroll Support: CommitGraph.WithInfiniteScroll enhances user experience for large commit histories by dynamically loading new content as users scroll.
• Customizable Styles: Extensive styling options for the commit log graph, including node colors, spacing, and more, to seamlessly match your project's design.

npm install commit-graph

For a basic implementation without infinite scroll:

import React from "react";
import { CommitGraph } from "commit-graph";

const MyComponent = () => {
  const commits = [
    // Commits data according to the new Commit type
  ];
  const branchHeads = [
    // Branch heads data according to the new Branch type
  ];

  return (
    <CommitGraph
      commits={commits}
      branchHeads={branchHeads}
      graphStyle={{
        commitSpacing: 50,
        branchSpacing: 20,
        branchColors: ["#FF0000", "#00FF00", "#0000FF"],
        nodeRadius: 2,
      }}
    />
  );
};

export default MyComponent;

For implementations requiring infinite scroll to handle large commit histories:

import React from "react";
import { CommitGraph } from "commit-graph";

const MyComponent = () => {
  // Your commit and branch head data, loadMore function, and hasMore flag
  return (
    <CommitGraph.WithInfiniteScroll
      commits={/* Your commits data */}
      branchHeads={/* Your branch heads data */}
      loadMore={/* Your loadMore function */}
      hasMore={/* hasMore flag */}
    />
  );
};

export default MyComponent;

• commits (array): An array of Commit objects representing the commit history.
• branchHeads (array): An array of Branch objects representing the branch heads in the commit-graph.

• loadMore (function): Function to load more commits upon reaching the scroll end.
• hasMore (boolean): Indicates whether more commits are available to load.

These type definitions should be used to structure the data passed to the commits and branchHeads props of both CommitGraph and CommitGraph.WithInfiniteScroll components, ensuring proper visualization of commit history and branch information.

The Commit type represents individual commits in the commit history. Each Commit object should conform to the following structure:

type ParentCommit = {
  sha: string;
};

export type Commit = {
  sha: string;
  commit: {
    author: {
      name: string; // The name of the commit author
      date: string | number | Date; // The date of the commit
      email?: string; // The email of the commit author (optional)
    };
    message: string; // The commit message
  };
  parents: ParentCommit[]; // An array of parent commits
  html_url?: string; // The URL to view the commit (optional)
};

This type definition includes the commit's SHA, author information, commit message, an array of parent commits, and an optional URL to the commit.

The Branch type defines the structure for branches in the repository, each associated with a particular commit:

export type Branch = {
  name: string; // The name of the branch
  commit: {
    sha: string; // The SHA of the latest commit on the branch
  };
  link?: string; // A URL to the branch on GitHub (optional)
};

Each Branch object should include the branch's name, the SHA of the latest commit on the branch, and an optional link to the branch.

An optional object specifying the styling options for the commit-graph. The graphStyle object should have the following properties:

• commitSpacing (number): The vertical spacing between commits.
• branchSpacing (number): The horizontal spacing between branches.
• branchColors (array of strings): An array of colors to be used for different branches. Default: ['#FF0000', '#00FF00', '#0000FF'].
• nodeRadius (number): The radius of the commit node circles.
