Pipe between async iterators and streams.
npm install async-iterator-pipeThe source should be an async iterable. Node.js readable
streams have experimental support for async iterators, so
those work too. The stages should be a sequence of streams
or functions that accept an async iterator and return a new
async iterator to transform or receive the values from the
source or previous stage in the sequence.
The final stage in the sequence will be returned, much like
stream.pipe(target) returns the target on Node.js streams.
const pipe = require('async-iterator-pipe')
const http = require('http')
async function* upper (iterator) {
for await (let chunk of iterator) {
yield chunk.toString().toUpperCase()
}
}
const server = http.createServer(async (req, res) => {
try {
req.setEncoding('utf8')
await pipe(req, upper, res)
} catch (err) {
res.writeHead(500, {
'content-type': 'text/plain'
})
res.end(err.message)
}
