let istream = createWriteStream(targetFileName, { mode });
istream.once('finish', () => c(null));
istream.once('error', e);
stream.once('error', e);
stream.pipe(istream);
}));示例2: done
writable._write = (input, encoding, done) => {
if (readable.push(input)) {
done();
} else {
readable.once('drain', done as (...args: any[]) => void);
}
};示例3: Promise
const p = new Promise((resolve, reject) => {
const error = (err: any) => {
if (err) {
// null check
err.bufferedData = stream.getBufferedValue();
}
reject(err);
};
stream = bufferStream(opts);
inputStream.once("error", error);
inputStream.pipe(stream);
stream.on("data", () => {
if (stream.getBufferedLength() > maxBuffer) {
reject(new Error("maxBuffer exceeded"));
}
});
stream.once("error", error);
stream.on("end", resolve);
clean = () => {
// some streams doesn't implement the `stream.Readable` interface correctly
if (inputStream.unpipe) {
inputStream.unpipe(stream);
}
};
});示例4: mkdirp
return mkdirp(targetDirName, void 0, token).then(() => new TPromise((c, e) => {
if (token.isCancellationRequested) {
return;
}
istream = createWriteStream(targetFileName, { mode });
istream.once('close', () => c(null));
istream.once('error', e);
stream.once('error', e);
stream.pipe(istream);
}));示例5: createWriteStream
return Promise.resolve(mkdirp(targetDirName, undefined, token)).then(() => new Promise<void>((c, e) => {
if (token.isCancellationRequested) {
return;
}
try {
istream = createWriteStream(targetFileName, { mode });
istream.once('close', () => c());
istream.once('error', e);
stream.once('error', e);
stream.pipe(istream);
} catch (error) {

}
}));示例6: onData
function onData(stream: Readable, session: SMTPServerSession, callback: (err?: Error) => void): void {
console.log(`[${session.id}] onData started`);
let messageLength = 0;
stream.on('data', (chunk: Buffer) => {
console.log(`[${session.id}] onData got data chunk ${chunk.length} bytes`);
messageLength += chunk.length;
});
stream.once('end', () => {
console.log(`[${session.id}] onData finished after reading ${messageLength} bytes`);
callback();
});
