Command line basics like git init, add, commit, push and pull integrate into editors for seamless versioning. Additional configs enforce code reviews through pull requests.
Install Core Dev Tools
Helpful utilities boost productivity in development. Node comes bundled with a package runner (node), debugger (node debug) and REPL shell for testing.
Linters standardize formatting with .eslintrc configs. Build tools automate compilation of assets through webpack. Mocking libraries prototype APIs while isolating units for testing.
With rock-solid environments, every contributor can focus fully on craft. Customizations promote collaboration and progressive enhancement.
Build on Strong Foundations
Data architecture underpins the entire application. Critical decisions here impact longevity.
Design Database Schemas
Follow normalization best practices when planning schemas to avoid duplication. Conceptual, logical then physical models illustrate relationships between entities.
Connect to MongoDB with Mongoose
MongoDB provides scalable document storage through its Node.js driver. Mongoose abstracts complex operations and enforces schemas for validation:
const mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/shop');
const productSchema = new mongoose.Schema({
name: String,
price: Number
});
const Product = mongoose.model('Product', productSchema);
Connect to SQL Databases with Sequelize
Sequelize establishes connections to relational databases like PostgreSQL through models and queries:
const Sequelize = require('sequelize');
const sequelize = new Sequelize('database', 'user', 'password', {
host: 'localhost',
dialect: 'postgres'
});
const User = sequelize.define('user', {
name: Sequelize.STRING
});
Model Product, User and Order Data
Define schemas flexibly to support new features over time. Associations link relations while maintaining normalization.
By standardizing on ORM abstractions, models remain portable across database backends. Their simplicity focuses attention on domain logic.
Empower Collaboration with APIs
Well-designed interfaces connect frontend experiences to flexible backends.
Define RESTful API Endpoints
Use HTTP verbs on predictable routes to perform CRUD actions. Define resources clearly – /products instead of /getProducts.
Secure APIs with Authentication
Passport strategies authenticate users through tokens. Middleware attaches req.user to access username, profile etc.
:
app.get('/me',
passport.authenticate('jwt', { session: false}),
(req, res) => {
res.json({ user: req.user });
}
);
Validate Requests with Middleware
Guard against injection, XSS etc. Format validators confirm data types and ranges. Parameter validation checks for required fields.
Version and Document Your APIs
API blueprinting tools help clients consume contracts securely. Semantic versioning allows breaking changes only in major releases to avoid errors.
Swagger/OpenAPI definitions self-document endpoints and responses. Guidelines clarify versioning philosophy, auth and error handling for expectations management.
Robust APIs energize reusability across clients through a consistent contract governing collaborative development between frontend and backend teams.
Frontend Development with Pug and Stylesheets
Bring APIs to life through attractive and composable user interfaces.
Set Up Pug Templating
Pug templates extend HTML for cleaner server-side rendering through mixins, flow control and includes. Layouts define shared sections for DRY views.
Add Styling with CSS/SASS
Preprocessors like Sass nurture maintainable styles through nesting, variables and mixins. Mobile-first methodologies future-proof responsiveness.
Integrate APIs with Fetch Requests
Consume APIs through asynchronous GET/POST using the Fetch API:
fetch('/products')
.then(res => res.json())
.then(products => {
products.forEach(product => {
// render products
});
});
Implement React/Vue Components
Component libraries decompose UIs into reusable pieces. Declarative frameworks increase productivity through virtual DOM diffing and dependency management compared to jQuery.
Modularity through single responsibility components and state management with libraries like Redux delivers maintainable and performant shop interfaces. Unit testing isolates logic for quality.
Adopting frontend standards produces templates that scale happily alongside backend changes with synchronicity for collaboration.
Product Management Features
Core functionality brings products to market through engaging catalogs.
Add Products Dynamically
Admin dashboards leverage CRUD components to manage inventories conveniently. Form validation protects data integrity.
Display Products Catalog
Product pages showcase items attractively while obeying homepage layouts. Flexible components allow reusability across categories.

Faceted navigation and full-text search empower discovery. Filter by attributes like brand, price or ratings.
Manage Variations and Inventory
Variant options for size and colors populate dropdowns. Integrations with stock APIs adjust availability automatically based on purchases.
Admins gain insights into best-sellers or low inventory through analytics dashboards. Reports clarify activities to informed decision making.
Adherence to DRY principles through separating concerns future-proofs the catalog schema. Products delight shoppers through compelling presentation optimized for conversion.
Handle User Accounts
Enabling personalized experiences builds loyal customer relationships.
Add User Registration
Registration forms capture needed profile info. Password hashing and salting protect credentials during storage and transmission.
Implement Authentication
Strategies like JWTs authenticate users securely via tokens. Sessions store login/logout activities. Passport middleware ties accounts to req.user.
Secure Private Routes and Data
Ensure only owners can access profiles by validating tokens on private routes. Hide admin/customer data based on roles.
Send Account Emails
Events trigger transactional emails – welcome messages, password resets, order confirmations. Templates provide consistent branding across common journeys.
User profiles consolidate activities and settings. User-centric features deepen understanding through post-purchase engagement. Admins supervise members centrally for support.
Standard practices here establish the foundation for personalized experiences respecting security and privacy through all interaction points.
