Project Setup Essentials
A well-structured project is the foundation of a solid SaaS — easier to read, maintain, and scale. This lesson sets up your environment and organizes your files.
Your Development Workspace
Your development environment is where you write, test, and run code: a code editor like VS Code, a terminal, and the runtime for your language.
Setting Up Node.js & npm
Node.js runs JavaScript outside the browser — a popular backend choice. It ships with npm, the package manager for installing and sharing libraries.
Starting Your Project with npm
Start a project with npm init in your project directory. It asks a few questions and creates a package.json — add -y to accept the defaults.
/*
In your terminal, run these commands:
1. mkdir my-saas-app
2. cd my-saas-app
3. npm init -y
The '-y' flag answers 'yes' to all prompts
and creates a default package.json file.
*/The `package.json` File
package.json is the heart of a Node project: name, version, entry point, custom scripts, and the dependencies your app needs to run.
Organizing Your Project
A consistent directory structure keeps a project legible. A common top level: src/ for code, public/ for assets, config/, tests/, and docs/.
Backend Structure: `src/`
Inside src/, separate concerns: controllers handle requests, services hold business logic, models map data, and routes define endpoints.
Your App's Entry Point
The entry point — set by main in package.json, often src/index.js — is where execution begins. This snippet just boots a simple app.
// This is your application's starting point.
function initializeApp() {
console.log("SaaS application is starting up...");
// In a real app, you'd connect to a database,
// set up your server, load configurations, etc.
console.log("Initialization complete.");
}
// Call the main initialization function.
initializeApp();Managing Configuration
Keep config out of code. Use environment variables (a .env file) for secrets and per-environment settings — and never commit sensitive keys to version control.
