Nodejs download file
I have created functions for all of them. To get the examples working makes sure you have the dependencies and the app variables set up and defined. get is Node's built-in method for making HTTP GET requests, which can also be used for downloading files using the HTTP protocol. The advantage of using HTTP. get is that you don't rely on any external programs to download the files. This is what the function above does: Make a HTTP. get request and create a writable stream using fs.
Since the HTTP. get 's response is a stream, it has the data event, which carries the chunks of data sent by the server. One each data event, write the data to the writeable stream. Once the server finishes sending data, close the instance of fs.
If you use fs. write or fs, nodejs download file. writeFile or any of their variants, they will fail for medium to large files. Use fs. createWriteStream instead for reliable results. To download files using curl in Node. Nodejs download file are using spawn instead of exec for the sake of convenience - spawn returns a stream with data event and doesn't have buffer size issue unlike exec.
That doesn't mean exec is inferior to spawn nodejs download file in fact we will use exec to download files using wget, nodejs download file. The way data was written to the instance of fs. createWriteStream is similar to way we did for HTTP. The only difference is that the data and end events are listened on the stdout object of spawn. Also we listen to spawn 's exit event to make note of any errors. Although it says downloading using wgetthis example applies to downloading using curl with the -O option too.
This method of downloading looks the most simple from coding point of view. Why exec and not spawn? Because we just want wget to tell us if the work was done properly or not, we are not interested in buffers and streams. We are making wget do all the dirty nodejs download file of making request, handling data, and saving the file for us. As you might have guessed, this method is the fastest among the three methods I described, nodejs download file. So now the question is - which method is the best?
The answer - whatever suits your need. The wget method is probably the best is you want to save the files to the local disk, but certainly not if you want to send those files as a response to a current client request; for something like that you would need to use a stream.
All the three methods have multiple options, you choice will ultimately depend on what your needs are. Programming TCP sockets in Node. js Eager to know how sockets are programmed in Node?
