Node.js script

Definition

A Node.js script is a JavaScript or TypeScript program that runs in Node.js rather than in a web browser. These scripts often work with files, databases, APIs, command-line input, or project tooling.

Why it matters

Node.js scripts are common in modern web projects because the same language used for app code can also automate project tasks. They are often used for imports, seed data, reports, and maintenance work.

Example in VCA

In VCA, learners may run Node.js scripts with tools such as tsx to seed a Prisma database or convert lesson content.

Another Real World Example

A team might use a Node.js script to read a CSV file and create database records during a content migration.

Common mistakes

• Forgetting that Node.js scripts can access production services if the environment points there.
• Mixing browser-only APIs with Node.js code.
• Not closing database connections after the script finishes.
• Running a script before dependencies are installed.
• Ignoring TypeScript errors in maintenance scripts.
