Support appending files with `Bun.write`

[lsyuanyuan]

What is the problem this feature would solve?

I read the document and the current way Bun writes files is:

const data = `It was the best of times, it was the worst of times.`;
await Bun.write("output.txt", data);

If new content needs to be added and written, then the node: fs module needs to be used,

import { appendFile } from "node:fs/promises";

await appendFile("message.txt", "data to append");

Is it being considered to add an optional parameter to Bun.write() or introduce a new method like Bun.appendWrite() to indicate appending new content? I feel this aligns well with Bun's inherent characteristics and makes it more concise

What is the feature you are proposing to solve the problem?

Add an optional parameter to Bun.write() or introduce a similar method Bun.appendWrite()

What alternatives have you considered?

Using the solution introduced in the official documentation

FileSink does what you're looking for: https://bun.sh/docs/api/file-io#incremental-writing-with-filesink

FileSink does not, it clears file content first before writing.

You're right, I realized that after I wrote this and forgot to come back and change this. Thank you for making this clear.
