Question:

In a generic sense (aka, not within any particular tool or framework, not the behavior of the tool or framework that you work in)...

If you had an HTML file that looked like this:

<!doctype html>
<script type="module">
  export default "jsvalue"

High-level file system organization for company-wide monorepo

The following are some high level options for organizing a company-wide monorepo.

This is assuming use of a multi-package system like Yarn, Bolt, or Lerna.

Option 1: Flat

Keep all of the packages at the top level so that you don't have to navigate deep into folders to find the package you are looking for. It's always one cd package-name away. It does mean that you have to name folders carefully so that related ones get grouped together.

View example.md
  • /my-website/
    • package.json
    • /src/
      • /pages/
        • index.html
        • about.html
      • /assets/
        • site.css
        • site.js
        • service-worker.js
You can’t perform that action at this time.
