When building applications, you typically need some way to show the build version somewhere in your app. This can be tricky when using a closed-ecosystem tool like the Angular CLI. So how do we do it then??
Lets write a script that will get the Git hash and the version from the package.json. This looks something like this:
Lets hook this script up to run on postinstall of our application. So navigate to your package.json and add this line to the scripts:
{
scripts: {
"postinstall": "node version.js"
}
}Now anytime we run npm i our app version will get updated for us.
This script will create a file in our environments folder called version.ts. It will look something like this:
We can now import that file in any component like:
Presto! Now we have our versions showing up in our app. That example just shows the semver but with the git script we have we can add the git hash too!
