Stop juggling terminals and fighting file permissions. With MMM-DevContainer you can develop MagicMirror in VS Code using either Docker Compose or Dev Containers — your choice.

Why it’s better:

One workspace for everything: modules, config and css all in one place. No more multiple windows or scattered folders.
Works with Docker Compose and/or VS Code Dev Containers: pick the workflow that fits your setup.
No file-rights hassle: edit and save directly from VS Code without sudo/chmod pain (unlike editing inside a running MM Docker container - if you’ve ever tried that).
Reproducible, clean environment: consistent installs, easy onboarding, and less “it works on my machine.”
Great DX: built-in terminals, IntelliSense, debugging, and Git — all inside the container.
npm install runs automatically on first start, so you can get coding faster.
Get started: https://github.com/HeikoGr/MMM-DevContainer

Quick start

• Clone the repo:
  git clone --depth=1 https://github.com/HeikoGr/MMM-DevContainer.git
cd MMM-DevContainer
• Add your module:
  Create your module inside modules/YourModule (or add it as a Git submodule).
• Keep MagicMirror core, your modules, and config together in this single workspace.
• Choose your workflow from below:

Option A — Docker Compose
docker compose up --build
Open the app in your browser (e.g., http://localhost:8080)
Stop when done: docker compose down

Option B — VS Code Dev Container
Install VS Code + the “Dev Containers” extension.
Open the MMM-DevContainer folder in VS Code.
Reopen in Container when prompted (or use Command Palette: “Dev Containers: Reopen in Container”).

Notes:
At the moment it’s only testet on linux (or windows with ssh on linux…)
Dependencies: npm install runs automatically on first start (via the devcontainer/compose setup). If your module needs extra dependencies, you can still run npm install inside the container terminal.
All source folders are mounted into the container; edits happen from VS Code without permission issues.
Suggestions and feedback welcome!
