API

Both methods returns a promise that is resolved when the end event fires on the stdin stream, indicating that there is no more data to be read.

getStdin(options) ← Promise<String>

Get stdin as a string.

In a TTY context, a promise that resolves to an empty string is returned, unless options.tty or getStdin.tty is true.

getStdin.buffer() ← Promise<Buffer>

Get stdin as a Buffer.

In a TTY context, a promise that resolves to an empty Buffer is returned.

Options / Settings

• tty | getStdin.tty (Boolean) - Set global TTY handling. When true, accepts input from TTY until a new line beginning with Ctrl-d or Ctrl-z is entered. Double Ctrl-d anywhere in the line also ends the stream. (Default = true)

  When enabled for the example above:

  	```
  	$ node example.js
  	foobar
  	barfoo
  	^d
  	// =>
  	foobar
  	barfoo
  	```

• EOF | getStdin.EOF (String) - The end-of-file (aka EOT) character to use to signal end of stream. Defaults to Ctrl-d on *nix and cygwin, and Ctrl-z on Windows. Acceptable values:

  • getStdin.CTRL_D - Ctrl-d (ASCII 04)
  • getStdin.CTRL_Z - Ctrl-z (ASCII 26)

  • '*' - Use both Ctrl-d and Ctrl-z

    ```bash
    (win) c:\> node example.js
    foobar
    ^z
    # => foobar
    ```
    ```bash
    $ node example.js
    foobar^d^d
    # => foobar
    ```
