read 1.0.7

The "read" npm package is a useful tool that facilitates the reading of user input from stdin in Node.js programs. It has similar functionality to the 'readline' builtin's 'question()' method but incorporates additional features, allowing for a more bespoke usage tailored to specific requirements. Key features include setting a custom prompt, silencing output, replacing silenced characters, defining a timeout, setting a default value, enabling or disabling user edit of default value, defining a terminal type, setting input and output streams, and even providing an autocomplete callback.

The usage of "read" in JavaScript is quite straightforward. First, you need to import the "read" module using the require function. Then, you can call the read function with two arguments - options and callback. Let's consider the following example:

var read = require("read");

// Set some options
var options = {
  prompt: "What's your name? ", 
  silent: false, 
  default: "Anonymous"
};

// Read user input, using the prompt defined above
read(options, function(er, name){
  if (er) {
    console.error("An error occurred: ", er);
  } else {
    console.log("Hello, " + name);
  }
});

Please note how the options argument allows for customization of the input prompt, the silence level, and the default value. The callback function processes the user input or handles any possible error.

The "read" documentation can be found within the README file present on the "read" GitHub page, accessible via https://github.com/npm/read. The documentation provides detailed information on usage, various options for configuration, and contributing guidelines. For more in-depth details about 'readline' options such as completer, you can refer to the official Node.js readline API at https://nodejs.org/api/readline.html#readline_readline_createinterface_options.
