Welcome to Clean-Stack: Your Comprehensive Guide to Modern API Development

In today’s fast-evolving technological landscape, a clean and efficient codebase is paramount. Introducing clean-stack, a robust framework designed to simplify and streamline your software development process. This article will walk you through the various APIs offered by clean-stack, complete with practical code snippets and an application example.

Getting Started with Clean-Stack

Clean-stack is a versatile toolset aimed at making API development a breeze. Let’s dive into some of its core functionalities.

Authentication

Secure your API endpoints with clean-stack’s authentication module:

const { authenticate, authorize } = require('clean-stack/auth');

app.post('/login', authenticate('local'), (req, res) => {
  res.json({ msg: "Logged in successfully" });
});

app.get('/protected', authorize('jwt'), (req, res) => {
  res.json({ msg: "Access granted" });
});

Data Validation

Ensure the integrity of your application data with built-in validation:

const { validate } = require('clean-stack/validate');

const userSchema = {
  name: { type: String, required: true },
  email: { type: String, required: true, match: /.+@.+\..+/ }
};

app.post('/register', validate(userSchema), (req, res) => {
  // Assuming user registration logic here
  res.json({ msg: "User registered successfully" });
});

Error Handling

Handle application errors efficiently:

const { errorHandler } = require('clean-stack/error');

app.use(errorHandler());

// Example of throwing an error
app.get('/error', (req, res, next) => {
  const err = new Error("Something went wrong");
  next(err);
});

Sample Application Using Clean-Stack

Let’s culminate our understanding with a sample application that utilizes the above APIs:

const express = require('express');
const { authenticate, authorize, validate, errorHandler } = require('clean-stack');

const app = express();
app.use(express.json());

const userSchema = {
  name: { type: String, required: true },
  email: { type: String, required: true, match: /.+@.+\..+/ }
};

app.post('/register', validate(userSchema), (req, res) => {
  // Register user logic
  res.json({ msg: "User registered successfully" });
});

app.post('/login', authenticate('local'), (req, res) => {
  res.json({ msg: "Logged in successfully" });
});

app.get('/protected', authorize('jwt'), (req, res) => {
  res.json({ msg: "Access granted" });
});

app.use(errorHandler());

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

There you have it! A full-fledged application exemplifying the robust capabilities of clean-stack. Happy coding!
