Node-request - How to determine if an error occurred during the request?

Question

I\'m trying to leverage the node-request module, but the documentation isn\'t that great. If I make a request to a valid resource and pipe it to a Writable Stream, everythin

Answer 1

The way I ended up succeeding with new Streams in node:

function doQuery(){
    var r = request(url)
    r.pause()
    r.on('response', function (resp) {
       if(resp.statusCode === 200){
           r.pipe(new WritableStream()) //pipe to where you want it to go
           r.resume()
       }else{  }
    })
}

This is really flexible - if you want to retry, you can call the function recursively with setTimeout

function doQuery(){
    var r = request(url)
    r.pause()
    r.on('response', function (resp) {
       if(resp.statusCode === 200){
           r.pipe(new WritableStream()) //pipe to where you want it to go
           r.resume()
       }else{ 
           setTimeout(doQuery,1000)
       }
    })
}
