Introduction to git-last-commit

In the world of version control, understanding the details of the last commit is crucial for development efficiency. The git-last-commit API allows developers to extract vital information about the most recent commit in a Git repository. This guide covers various useful APIs provided by git-last-commit with practical code snippets and an app example to demonstrate its usage.

API Examples

Latest Commit Hash

Fetch the most recent commit hash:

  
    const getLastCommit = require('git-last-commit');
    
    getLastCommit((err, commit) => {
      console.log(commit.hash);
    });
  

Latest Commit Message

Retrieve the message of the latest commit:

  
    getLastCommit((err, commit) => {
      console.log(commit.subject);
    });
  

Latest Commit Author

Access the author of the most recent commit:

  
    getLastCommit((err, commit) => {
      console.log(commit.committer.name);
    });
  

Latest Commit Date

Obtain the date of the latest commit:

  
    getLastCommit((err, commit) => {
      console.log(commit.committer.date);
    });
  

App Example

Here’s a simple Node.js application that uses git-last-commit to display the latest commit details:

  
    const getLastCommit = require('git-last-commit');
    const express = require('express');
    const app = express();
    
    app.get('/latest-commit', (req, res) => {
      getLastCommit((err, commit) => {
        if (err) {
          return res.status(500).send(err);
        }
        res.json(commit);
      });
    });
    
    const PORT = process.env.PORT || 3000;
    app.listen(PORT, () => {
      console.log(`Server is running on port ${PORT}`);
    });
  

With this application, you can easily view the details of the latest commit by accessing the /latest-commit endpoint.

By leveraging these APIs, developers can better manage and understand their Git repositories, leading to increased productivity and more efficient workflows.
