Here's an example code snippet to create a simple server component and decode cookies in TypeScript:

index.ts
import express from 'express';
import cookieParser from 'cookie-parser';

const app = express();

// Middleware to parse cookies
app.use(cookieParser());

app.get('/', (req, res) => {
    // Reading a cookie
    const cookieValue = req.cookies.cookieName;

    res.send(`Cookie Value: ${cookieValue}`);
});

const PORT = 3000;
app.listen(PORT, () => {
    console.log(`Server is running on http://localhost:${PORT}`);
});

In this code:

1. We import express and cookie-parser packages.
2. We create an Express app.
3. We use cookieParser middleware to decode cookies in the incoming requests.
4. In the route handler, you can access the cookie values through req.cookies.<cookieName>.

Remember to replace 'cookieName' with the name of the cookie you want to read.

Make sure to run your TypeScript code using a TypeScript compiler (like tsc) or using a tool like ts-node.

This simple server component will be able to read and decode cookies in TypeScript using Node.js with the help of Express and cookie-parser packages.
