I'm building a standardized dev environment for multiple repos

Great goal — a standardized dev environment can save a lot of time across repos.

A good setup usually answers these questions:

1. How do developers get a consistent environment?

   • Docker / Dev Containers
   • Nix / direnv
   • ASDF / mise for language/tool versions
   • Virtualenv / Poetry / pnpm / etc. per stack

2. How do you standardize the workflow?

   • One command to bootstrap: make setup or task init
   • One command to test: make test
   • One command to run: make dev
   • Consistent lint/format hooks

3. How do you manage per-repo differences?

   • Common base template + repo-specific overrides
   • Shared scripts/templates in a central tooling repo
   • Optional config file in each repo, e.g. .devcontainer/devcontainer.json, tool-versions, mise.toml, etc.

4. How do you keep it maintainable?

   • Version the environment definition
   • Pin tool versions
   • Automate updates
   • Document the supported commands and prerequisites

If you want, I can help you design this in one of these ways:

• Docker-based standardized dev env
• Dev Containers for VS Code / Cursor
• Nix-based reproducible environment
• Language-tool version manager approach
• A hybrid pattern for multiple repos

If you tell me:

• your main languages/frameworks,
• whether this is for local dev, CI, or both,
• and whether you want Docker,

I can propose a concrete architecture and file layout.
