Why does a written file from base64/Buffer fail?

Question

JavaScript

I get the base64 representation of the file. I'm trying to write to a file. It can be pdf/docx/jpeg, whatever.

The recording is normal, but when you try to open it, an error appears that the file may be damaged or incorrectly recorded.

const docBuffer = Buffer.from(content[1].trim(), 'base64');

    const stream = new Readable();

    const writeStream = createWriteStream(
        process.cwd()+'/file/'+name,
    );

    stream.push(docBuffer);
    stream.push(null);

    stream.pipe(writeStream);

Thank you for your help!

Answer 1

const filePath = path.join(process.cwd(), "file", name)

fs.writeFile(filePath, base64, "base64", (err) => {
            if (err) console.log(err)
        })

Try it like this - without extra code
