what does AWS CodePipeline build provider do?

Question

I am beginner at using AWS .so i want to ask some questions about CodePipeline.

so all i know about CodePipeline ,that i can connect it to github repo to let my app updated automatically ... then when i am doing the steps something called build provider appeared (its optional) .. and when i skip it it says "Your pipeline will not include a build stage"

so why do i have to do a build provider when my project compiled and build successfully locally on my PC ,i know its an optional step ,so can i know what it do exaclty ?

Answer 1

When you are automating your code deployment process you cannot build your code locally as its a manual process.

To Automate the process code-pipeline has a build provider which can build your code as n when required. So, that you don't need to checkout the code locally and build before deploying.
