1.Introduction
A Full Stack Native Programmer specializes in building native applications across platforms, working with front-end UI frameworks, back-end services, databases, and APIs.- Key Technologies:
- Front-End (Native UI): Swift (iOS), Kotlin (Android), React Native, Flutter.
- Back-End: Node.js, Python (Django, Flask), Java (Spring Boot), C# (.NET).
- Database: MySQL, PostgreSQL, Firebase, MongoDB.
- DevOps & Deployment: Docker, AWS, CI/CD, Google Play Store, Apple App Store.
import SwiftUI
struct ContentView: View {
var body: some View {
Text("Hello, iOS!")
.padding()
}
}
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
}
}
import React from "react";
import { View, Text } from "react-native";
export default function App() {
return (
<View>
<Text>Hello, React Native!</Text>
</View>
);
}
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(title: Text("Flutter App")),
body: Center(child: Text("Hello, Flutter!")),
),
);
}
}
2.Back-End Development (Node.js, Python, Java, C#)
Node.js & Express.js API
const express = require("express");
const app = express();
app.get("/", (req, res) => {
res.send("Hello, Backend!");
});
app.listen(3000, () => console.log("Server running on port 3000"));
from flask import Flask
app = Flask(__name__)
@app.route("/")
def home():
return "Hello, Flask!"
if __name__ == "__main__":
app.run(debug=True)
@RestController
public class HelloController {
@GetMapping("/")
public String hello() {
return "Hello, Spring Boot!";
}
}
using Microsoft.AspNetCore.Mvc;
[Route("/")]
public class HomeController : Controller
{
public string Index() => "Hello, .NET Core!";
}
3.Database Management (SQL & NoSQL) ️
SQL Database Example (MySQL/PostgreSQL)
CREATE TABLE users (
id SERIAL PRIMARY KEY,
name VARCHAR(100),
email VARCHAR(100) UNIQUE
);
const mongoose = require("mongoose");
mongoose.connect("mongodb://localhost:27017/mydb", { useNewUrlParser: true });
const UserSchema = new mongoose.Schema({ name: String, age: Number });
const User = mongoose.model("User", UserSchema);
User.create({ name: "Alice", age: 25 });
import firebase from "firebase/app";
import "firebase/database";
const db = firebase.database();
db.ref("users/1").set({ name: "Alice", age: 25 });
4.Authentication & Security
JWT Authentication in Node.js
const jwt = require("jsonwebtoken");
const token = jwt.sign({ id: 123 }, "secretkey", { expiresIn: "1h" });
jwt.verify(token, "secretkey", (err, decoded) => {
if (err) console.log("Invalid Token");
else console.log("User ID:", decoded.id);
});
const bcrypt = require("bcrypt");
const password = "mypassword";
const hashedPassword = bcrypt.hashSync(password, 10);
console.log(bcrypt.compareSync("mypassword", hashedPassword)); // true
5.RESTful API Development & GraphQL
REST API with Express.js
app.get("/users", (req, res) => {
res.json([{ id: 1, name: "John Doe" }]);
});
const { ApolloServer, gql } = require("apollo-server");
const typeDefs = gql`
type Query {
hello: String
}
`;
const resolvers = {
Query: {
hello: () => "Hello, GraphQL!"
}
};
const server = new ApolloServer({ typeDefs, resolvers });
server.listen().then(({ url }) => console.log(`Server ready at ${url}`));
6.DevOps & Deployment
Deploying with Docker 1.Create a Dockerfile
FROM node:14
WORKDIR /app
COPY package.json .
RUN npm install
COPY . .
CMD ["node", "server.js"]
EXPOSE 3000
docker build -t myapp .
docker run -p 3000:3000 myapp
sudo apt update
sudo apt install nodejs npm
pm2 start server.js
pm2 save
pm2 startup
7.Version Control with Git & GitHub
Git Commands| Command | Description |
| git init | Initialize a repository |
| git clone <repo> | Clone a repository |
| git add . | Stage changes |
| git commit -m “Message” | Commit changes |
| git push origin main | Push to remote repo |
| git pull origin main | Pull latest changes |
8.Testing & Debugging
Unit Testing with Jest (JavaScript)
const sum = (a, b) => a + b;
test("adds 1 + 2 to equal 3", () => {
expect(sum(1, 2)).toBe(3);
});
from django.test import TestCase
from .models import User
class UserTestCase(TestCase):
def test_user_creation(self):
user = User.objects.create(name="Alice")
self.assertEqual(user.name, "Alice")
