file stream to buffer in typescript

To stream a file into a buffer in TypeScript, you can use the fs module and Buffer class. Here's an example code snippet:

index.ts
import * as fs from 'fs';

const filePath = 'example.txt';

fs.readFile(filePath, (err, data) => {
    if (err) {
        console.error(err);
    } else {
        const buffer: Buffer = data;
        console.log(buffer);
    }
});

In this code:

1. We first import the fs module to work with the file system.
2. We specify the file path for the file we want to read (example.txt in this case).
3. We use the fs.readFile function to read the contents of the file asynchronously.
4. In the callback function, we check for any errors and if not, we convert the data into a Buffer and print it.

Remember to handle errors properly and adjust the file path and data processing according to your requirements.
