create pull-stream from async callback
npm install pull-asynccreate source pull-stream from async callback (more specifically, a _continuable_)
``shell`
npm install --save pull-async
if you want to resolve multiple values, use pull-defer.
`js
const pull = require('pull-stream')
const xhr = require('xhr')
pull(
pullAsync((cb) => {
xhr.get('/things', cb)
}),
pull.log()
)
// [{...}, {...}, {...}, ...]
`
a _continuable_ is a function that takes in a single argument: an error-first callback.
returns a source stream that will resolve the continuable into a single error or value, then end the stream.
`js``
function pullAsync (continuable) {
var done
return function (abort, cb) {
if (abort) return cb(abort)
if (done) return cb(true)
continuable(function (err, data) {
done = true
cb(err, data)
})
}
}
