close , not called explicitly. Speaking of handling errors, it's even better listening to request errors too. I'd even validate by checking response code. Here it's considered success only for response code, but other codes might be good. Despite the relative simplicity of this code, I would advise to use the request module as it handles many more protocols hello HTTPS! which aren't natively supported by http. gfxmonk's answer has a very tight data race between the callback and the file. close completing. close actually takes a callback that is called when the close has completed. Otherwise, immediate uses of the file may fail very rarely! Without scheduling the cb callback via close, you may get a race between accessing the file and the file actually being ready. Maybe node. js has changed, but it seems there are some problems with the other solutions using node v8. for those who came in search of es6-style promise based way, I guess it would be something like:.

Don't make file when you get an error, and prefere to use timeout to close your request after X secondes. In addition，when you want download large、multiple files，you can use cluster module to use more cpu cores. Modern version ES6, Promise, Node I decided do not use 3rd party libraries due to it can be easy done with standard Node. js libs. Kudo to Andrey Tkachenko for his gist which I modified. From my answer to "What's the difference between. pipe and. pipeline on streams". I saw answers using the http , https , and request modules. I'd like to add one using yet another native NodeJS module that supports either the http or https protocol:. I've referenced the official NodeJS API, as well as some of the other answers on this question for something I'm doing. The following was the test I wrote to try it out, which worked as intended:. It's typed, it's safer. Feel free to drop the types if you're working with plain JS no Flow, no TS or convert to a.

ts file. Here's yet another way to handle it without 3rd party dependency and also searching for redirects:. For Node with Promise support, a simple Node shim for part of the Fetch API requires only a smattering of extra code compared to other answers:. You can try using res. redirect to the https file download url, and then it will be downloading the file. I've found this approach to be the most helpful especially when it comes to pdfs and random other files.

quantumpotato Take a look at the response you're getting back from your request — Michelle Tilley. This depends upon the req url type if you are requesting https you must use https otherwise it will throw error. EthanKeiley why do you say that it isn't closed properly?

The request module just works straight for HTTPs. S Ventura. ventura yep, btw, there's also the native https module that now can handle secure connections. It's more error prone without a doubt. Anyway, in any case where using request module is an option, I'd advise it as it's way higher level and thus, easier and efficient. Alex, nope, this is an error message and there's a return. So if response. Thank you for showing example using request module.

However, when performing operations such as downloading files, we can also use built-in packages or modules that are part of Node js core by requiring them in our programs. The fs module provides us with the functionality to work with files on our system besides access to a range of asynchronous methods to perform other basic operations on files, such as renaming and deleting. On the other hand, Nodejs provides the standard HTTP and HTTPS modules in its standard library. Using this method, we can request a server using the same module. We can also create a server that listens to ports and responds. First, we will need to create a simple Node js application with the main file index. js to get started. Now under this file, using the require functions, we will require the fs module and HTTP module without any prior installations, as shown here. log "Current chunk of data: " , chunk ; console. log "Remaining bytes: " , remainingSize ; } , } ; try { await downloader.

Now under this file, using the require functions, we will require the fs module and HTTP module without any prior installations, as shown here. Using the http. get method, we will then pass in the endpoint to the resource that we want to download as the first argument, followed by a callback function whose work is to run once the file stream has been received and create the file in our local system using the name specified in the function.

The streaming process begins once the data is available to respond to the HTTP client. Using the streams powered Node js API fs. createWriteStream , we will create a writable stream to the file we want to make. This method accepts only one argument: the location where we want the file saved. Please note that since the fs module will automatically save this current folder, we have instead specified the name we want the file we are downloading. Finally, using the pipe method, usually called on the file stream, we will pipe the file stream to the HTTP response and close the write stream using the writeStream.
