function Deno.writeSync
writeSync(rid: number,data: Uint8Array,): number
Deprecated
This will be removed in Deno 2.0. See the Deno 1.x to 2.x Migration Guide for migration instructions.
Synchronously write to the resource ID (rid) the contents of the array
buffer (data).
Returns the number of bytes written. This function is one of the lowest
level APIs and most users should not work with this directly, but rather
use WritableStream, ReadableStream.from and
ReadableStream.pipeTo.
It is not guaranteed that the full buffer will be written in a single call.
const encoder = new TextEncoder(); const data = encoder.encode("Hello world"); using file = Deno.openSync("/foo/bar.txt", { write: true }); const bytesWritten = Deno.writeSync(file.rid, data); // 11
