Git-blame-line

Executes git blame asynchronously for a given <filepath>:<linenumber> string, and returns the information in JSON format.

Usage

You don't need to remember git syntax to get blame info for single line now. Instead of writing this:

git blame -L 19,+1 --line-porcelain src/index.ts

You can execute this from command line:

blame-line src/index.ts:19

And the output would be in the shape as:

{
  "author": "Berkan Unal",
  "authorMail": "[e-mail]",
  "authorTime": "2020-11-15T17:35:01.000Z",
  "authorTz": "+0300",
  "committer": "Berkan Unal",
  "committerMail": "[e-mail]",
  "committerTime": "2020-11-15T17:35:01.000Z",
  "committerTz": "+0300",
  "summary": "Remove babel webpack, add eslint, lint project",
  "previous": "816634e51cf31c2d7bd18b7a8b082aff539e1bcd src/index.ts",
  "filename": "src/index.ts",
  "sourceCode": "export async function blameLine(filepathWithLine: string): Promise<BlameInfo> {"
}

Installing for using inside a node project

yarn add git-blame-line

or

npm install git-blame-line

Then import in the project and use it easily like this ¹:

const { blameLine } = require("git-blame-line");
 
async function example() {
  const info = await blameLine("path/to/file:123");
  console.log(info);
}
 
example();

¹ You don't have to use requirejs syntax
