Stop Googling Git commands and actually learn it! That tag tells our YAML library to parse it as a function, which can then be executed later. As pointed out in the documentation, one common method that is executed on JS objects is toString , which we can exploit like this:. Open command prompt, change current directory to the root folder of our project. In controller package, we create file.

It exports 2 functions:. When a client sends HTTP requests, we need to determine how the server will response by setting up the routes. Following tutorials explain how to build Front-end Apps to work with our Node. The source code at the end of this post will cover all of APIs including upload files. You can find the complete source code for this tutorial on Github. Two comments on this: 1 it should probably reject Error objects, not strings, 2 fs. This works great! No errors popped up but the.

Removing the logic for the flag fixed it. Just wanted to point that out if someone had the issues with the approach. Is there a memory leak in this answer: stackoverflow. You can add timeout like I did in http. The memory leak is only if the file take too long to be downloaded. Based on the other answers above and some subtle issues, here is my attempt.

Check the file does not exist before hitting the network by using fs. Only create the fs. This reduces the amount of fs. Even on a OK we can still possibly reject due to an EEXIST file already exists imagine another process created the file whilst we were doing network calls. Recursively call download if you get a Moved Permanently or Found Moved Temporarily redirect following the link location provided in the header.

The issue with some of the other answers recursively calling download was that they called resolve download instead of download This way the nested chain of promises resolve in the correct order. It might seem cool to clean up the temp file asynchronously, but I chose to reject only after that completed too so I know that everything start to finish is done when this promise resolves or rejects.

You shouldn't waste resources doing the download if the destination file already exists. Do the check first if possible. Phil Really good point. I have updated the example with an earlier guard check before falling into the recursive networking calls but left the success file handling code the same. This short circuit guard statement should save some time in this case now. Vince Yuan's code is great but it seems to be something wrong. But we don't check the result if callback callback err.

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.
