can I have one build script for multiple packages?

[csenio]

Hey everyone,
I'm new to monorepos and was wondering if I could have one build config at the root of my project that builds each of my packages.

My project structure looks like this

|-packages
    |-button
        |-package.json
        |-src
           |-index.js
           |-button.svelte
    |-select
        |-package.json
        |-src
           |-index.js
           |-select.svelte
etc...

Previously, each of these packages had its own rollup.config.js and build script. I would prefer to have a single rollup.config.js and build script somewhere in the root of the project (that still gives each package its own dist folder). Is that possible with turborepo?

Not particularly a turbo specific problem, but you could create a root level config (or a package) for your base build config and extend that config in each package. (this is probably what I would do)

Alternatively you could create a separate build-tools package that builds a utility to programmatically run your build for the given package folder. So you could run something like this for each package:

"scripts": {
 "build": "custom-build --<any-custom-options>"
}

With this approach turbo would require you to list this a dev-dependency for each package so it knows to build that package first before everything else.
