To understand in simple terms, Node.js can be defined as follows:
The acronym for npm is the Node Package Manager. This package manager provides essential online repositories for Node.js modules and packages. You can also find these repositories on search.nodejs.org. Besides, it facilitates the command-line utility to install the packages. Not just these, it also does dependency and version management for the Node.js packages.
All the metadata details of the Node.js application project is maintained in the Package.json file. Generally, it is located in the root directory of every Node package or module. It is useful to get the data in the JSON Object format.
Here are some of the significant attributes belong to package.json:
main, name, version, homepage, description, contributors, author, dependencies, repository, keywords.
To truncate a file in Node.js we use the following syntax:
fs.ftruncate(fd, len, callback)
where fd – it is a file descriptor that is returned by a file fs.open() function,
len – it denotes the length of a file which is then truncated,
callback – it is a callback function that returns no arguments.
There are so many modules available for Node.js but among them, the most preferred and most downloaded modules that are recommended by most Node.js Software development companies are: express, browserify, bower, async, socket.io, grunt, gulp.
In order to provide cryptographic functionality Node.js uses the crypto module. It also includes a set of wrappers for HMAC, cipher, decipher, OpenSSL’s hash, sign, and verify functions.
To understand it better, consider the following example:
var crypto = require(‘crypto’);
var secret = ‘abcdefg’;
var hash = crypto.createHmac(‘sha256’,secret).update(‘I am good’).digest(‘hex’);
Many Node.js application development agencies make utilization of popular security tools in their Node.js web applications like helmet, csurf, cors, node rate limiter.
helmet – This a kind of security tool that protects your Node.js application by setting HTTP headers.
Csurf – It puts validations on tokens, verifies incoming requests, and rejects the invalid requests.
Cors – It assists us by enabling cross-origin resource sharing.
Node rate limiter – It controls and manages the rate of repeated requests and becomes a protection barrier from brute force attacks.
