What is @vercel/node?
@vercel/node is a serverless function runtime for Node.js, designed to be used with the Vercel platform. It allows developers to deploy serverless functions with ease, providing a seamless experience for building and deploying APIs, microservices, and other server-side logic.
What are @vercel/node's main functionalities?
Simple HTTP Endpoint
This feature allows you to create a simple HTTP endpoint that responds with 'Hello, world!'. It demonstrates how easy it is to set up a basic serverless function using @vercel/node.
const { createServer } = require('@vercel/node');
module.exports = (req, res) => {
res.status(200).send('Hello, world!');
};
Handling Query Parameters
This feature shows how to handle query parameters in your serverless function. The example responds with a personalized greeting based on the 'name' query parameter.
const { createServer } = require('@vercel/node');
module.exports = (req, res) => {
const { name = 'World' } = req.query;
res.status(200).send(`Hello, ${name}!`);
};
Handling JSON Requests
This feature demonstrates how to handle JSON requests in a serverless function. The example processes a POST request with a JSON body and responds with a personalized message.
const { createServer } = require('@vercel/node');
module.exports = (req, res) => {
if (req.method === 'POST') {
let body = '';
req.on('data', chunk => {
body += chunk.toString();
});
req.on('end', () => {
const data = JSON.parse(body);
res.status(200).json({ message: `Hello, ${data.name}!` });
});
} else {
res.status(405).send('Method Not Allowed');
}
};
