A back-end developer makes sure that everything behind the graphical interface works correctly.
Their work ranges from managing databases, servers and APIs to application security.
- Node.js: For building fast, scalable servers with JavaScript.
- Python: Using frameworks such as Django or Flask for robust APIs.
- Java: Widely used in enterprise applications through Spring Boot.
- Ruby on Rails: Ideal for startups looking for agility.
- Databases: MySQL, PostgreSQL and MongoDB are essential parts of their toolkit.
Here is a basic example of a Node.js server:
const express = require('express');
const app = express();
const PORT = 3000;
app.get('/', (req, res) => {
res.send('Hello from the server!');
});
app.listen(PORT, () => {
console.log(`Server running at http://localhost:${PORT}`);
});
