Using Buffers in Node.js : Node has several strategies for manipulating, creating, and consuming octet streams. Raw data is stored in instances of the Buffer class in node. In this tutorial we have covered how to create, read and write Buffers in Node in detail with examples. The very first things I had to do to set this up, were import the required functions from Node.js: fs (file system), readline, and stream.These imports allowed me to then create an instream and outstream and then the readLine.createInterface(), which would let me read through the stream line by line and print out data from it.. I also added some variables (and comments) to hold various bits of Node.js v0.10+ (latest stable is v0.10.15 as of this writing), but streams have generally been a part of Node.js from its early days; Streams2 can be used with older versions of node by using npm module readable-stream; Consuming or using readable streams. Simple example of reading a file and echoing it to stdout: In Node.js we can perform these operations using the File Module (fs) and the http module. Node.js scans the URL based on which it reads the corresponding html file and responds to the request message. In this article, we will create a Node.js project with a HTML file in it. The code above generates the following result. We can specify the index of the element where you want to insert a new element. If this element is past the last element, the elements in between are created and initialized with the value undefined : So, if you’re trying to do this in a browser: Browsers don’t give Javascript access to the file system directly. Thus, when you say, “create a txt file,” it’s not directly possible to arbitrarily open a file, write to it, and close it using Javasc
