Quick D2M2J Tutorial: Get Started in Under 10 MinutesD2M2J is a lightweight tool (or concept — adapt to your context) designed to simplify common workflows by offering a minimal, focused set of features. This quick tutorial will get you up and running in under 10 minutes, covering installation, basic configuration, a simple example, and tips for next steps.
What you need (time & prerequisites)
- Time: ~10 minutes
- Prerequisites: Basic familiarity with the command line, a text editor, and (if applicable) the runtime required by D2M2J (e.g., Node.js, Python, Java — adapt to your environment).
1) Install D2M2J (1–2 minutes)
Choose the installation method that matches your environment.
-
If D2M2J is published as an npm package:
npm install -g d2m2j -
If it’s a Python package:
pip install d2m2j -
If provided as a single binary (downloaded):
# on Unix-like systems chmod +x d2m2j && mv d2m2j /usr/local/bin/
After installation, verify:
d2m2j --version 2) Initialize a project (1 minute)
Create a new project directory and initialize D2M2J’s default config.
mkdir my-d2m2j-project cd my-d2m2j-project d2m2j init This creates a config file (e.g., d2m2j.config.json) and a minimal project structure.
3) Configuration overview (2 minutes)
Open the config file in your editor. Typical fields:
- entry — main input file
- output — destination folder or file
- mode — dev or production
- plugins — optional extensions
- options — feature toggles
Example config (JSON):
{ "entry": "src/main.js", "output": "dist/", "mode": "dev", "plugins": [], "options": { "minify": false, "sourcemaps": true } } Key tips:
- Use dev mode while learning for faster feedback.
- Enable sourcemaps for easier debugging.
4) Create a minimal example (2 minutes)
Add a simple source file so you can run a first command.
src/main.js:
console.log("Hello from D2M2J!"); Run the build/execute command:
d2m2j run Expected output: “Hello from D2M2J!” and an output bundle in the dist/ folder.
5) Common commands (30 seconds)
- d2m2j run — execute or serve the project
- d2m2j build — produce production-ready output
- d2m2j watch — rebuild on file changes
- d2m2j test — run tests (if supported)
- d2m2j help — show available commands
6) Troubleshooting (1 minute)
- If command not found: ensure the binary is in your PATH or use npx / python -m.
- Permission errors on Unix: use chmod +x and consider installing in /usr/local/bin.
- Runtime errors: check entry path in config and verify required runtime (Node/Python/Java) versions.
7) Next steps (optional)
- Add plugins for additional features (e.g., minification, formatters).
- Integrate into CI: run build in your pipeline.
- Explore advanced config options: multiple entries, output hashing, environment variables.
That’s it — you should now have a minimal D2M2J project running. If you tell me which runtime or specific D2M2J implementation you’re using (Node/Python/binary), I’ll tailor commands and examples to it.
