Runtime · Node.js
Needed before npm install or npm run dev can work.
Node.js is the runtime behind the package commands used by many modern web projects. In practice, it is what lets a Virex repo install dependencies, start a local dev server, and run a production build check.
Why it matters in the Virex flow
If a Virex repo includes a package.json with scripts, Node is usually part of the continuation path. Without it, a user can open the repo but not actually run the project locally.
When you need it
- When the repo includes install, dev, build, or lint scripts.
- When you want to run the generated project locally.
- When you need to verify the app before deployment.
What it does for you
- Lets you install project dependencies.
- Lets you run the local application.
- Lets you validate that the generated repo still builds cleanly.
What to do first
Each tool makes more sense when you know the first practical move instead of only reading a definition.
First practical action
Install Node.js before trying npm install or npm run dev. npm ships with Node, so you usually do not install npm separately.
Where this sits in the workflow
Node sits underneath the local run path. It is one of the earliest practical requirements for web repos that need install or dev commands.
Typical sequence after generation
Use this as the practical place to put the tool into context after a repo already exists.
Typical sequence
- Install Node.js on your machine.
- Open the repo and check the scripts in package.json.
- Run npm install, then npm run dev or npm run build when appropriate.

Use the docs path that matches your current level so the rest of the setup order stays understandable.
Start with the real repo, the first tool order, and the exact local steps you need to see the project running.
Use Virex as a structured baseline and continuation system instead of a one-shot prompt tool.
Treat Virex as a repo accelerator that still leaves the deeper engineering workflow in your hands.
Important context
Some future repos may continue in other runtime patterns too, but Node remains one of the main practical defaults for current web-oriented continuation.
