Looks like Request has been deprecated github. No new changes are expected to land. In fact, none have landed for some time. Wai Ha Lee 7, 60 60 gold badges 56 56 silver badges 85 85 bronze badges. Idan Dagan Idan Dagan 7, 3 3 gold badges 28 28 silver badges 38 38 bronze badges.

Roman Podlinov Roman Podlinov Very clean, thank you. What do the flags 'wx' do when you're creating the writeStream? It is returning garbage character if file name is other than ascii like if filename is in japanese. Do you think ajax-request is not a third party library?

Download using promise, which resolve a readable stream. The questions was specific to not include third party modes : — David Gatti. If you are using express use res.

I'd like to add one using yet another native NodeJS module that supports either the http or https protocol: Solution I've referenced the official NodeJS API, as well as some of the other answers on this question for something I'm doing. Rik Rik 3 3 silver badges 8 8 bronze badges. Is this backward compatible? Works everywhere or only for http2? Neil I'm assuming you are asking if http2 is backward compatible with http1. Because http2 improves framing; adding binary compression, the ability to push from server to client, and simultaneous connections - it is absolutely required that both server and client know the implementation this allows abstraction of implementation from the application too.

Good news is that all major browsers have supported http2 since about - and Node as a client does too. Node, Nginx, and Apache offer it server side - so most use cases are covered. Its a vast improvement. Thanks for the reply Rik — Neil. Without library it could be buggy just to point out. Here my suggestion: Call system tool like wget or curl use some tool like node-wget-promise which also very simple to use.

See CVE for further details. If a SHA checksum is passed to this parameter, the digest of the destination file will be calculated after it is downloaded to ensure its integrity and verify that the transfer completed successfully.

This option is deprecated and will be removed in version 2. Use option checksum instead. When run on Ansible prior to 2. Influence when to use atomic operation to prevent data corruption or inconsistent reads from the target file. By default this module uses atomic operations to prevent data corruption or inconsistent reads from the target files, but sometimes systems are configured or just broken in ways that prevent this.

One example is docker mounted files, which cannot be updated atomically from inside the container and can only be written in an unsafe manner. This option allows Ansible to fall back to unsafe methods of updating files when atomic operations fail however, it doesn't force Ansible to perform unsafe writes.

Requires the Python library gssapi to be installed. OK unknown bytes. The attributes the resulting file or directory should have. To get supported flags look at the man page for chattr on the target system. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment.

This is a bit messy but hopefully you get the idea. Thank you. Hello Mortiz, Apologize for the late response. If it fails there might be a problem with the credentials, the port or something else concerning the server encryption etc. Do you use the nodes in a loop? Published on Aug 6, by Phil Nash.

Got is a Node. The stream API gives us some extra benefits though. The promise API will load responses into memory until the response is finished before fulfilling the promise, but with the stream API you can act on chunks of the response as they arrive. This makes streams more memory efficient, particularly for large responses.

You can create a stream with Got using the stream method or by setting isStream to true in the options. A Got stream is a duplex stream , which means it is both readable and writable.
