In this article, I'll show you how to include basic GIT data in the Angular application. The data will be dumped to src/assets/version.json file and will consist of:

short hash
long hash
branch name
commit date

Set up the app

Init the test app with default settings:

ng new app --defaults=true

Navigate to the app directory:

cd app

Install the dependencies. I'll be using the git-rev-sync library.

npm i git-rev-sync

Implement the solution

Create a .gitignore file the src/assets directory and add the following content. This will prevent the file from being included in the repository.

version.json

Create the script file dump-git-info.js in the app's main directory. The flow is quite simple:

import the libraries
read git data
write file

// dump-git-info.js

const git = require('git-rev-sync');
const { writeFileSync } = require('fs');

const version = {
  short: git.short(),
  long: git.long(),
  branch: git.branch(),
  date: git.date(),
};

writeFileSync('./src/assets/version.json', JSON.stringify(version));

You can run the script with the following command:

npm i git-rev-sync

Check the file ./src/assets/version.json and you should see output similar to:

{"short":"386e4a5","long":"386e4a55e9e96018465754de172c351c68f7ff1f","branch":"master","date":"2023-04-15T13:45:30.000Z"}

Add the script to package.json:

{
  "scripts": {
    "dump-git-info": "node dump-git-info.js",
...

Also, add prebuild hook to run it automatically:

{
  "scripts": {
    "prebuild": "npm run dump-git-info",
...

From now on, whenever you run npm run build the version.json will be also created and accessible through /assets/version.json url in the browser.

$ npm run build

> app@0.0.0 prebuild
> npm run dump-git-info


> app@0.0.0 dump-git-info
> node dump-git-info.js
