read

For reading user input from stdin.

Similar to the readline builtin's question() method, but with a few more features.

Usage

const { read } = require('read')
// or with ESM: import { read } from 'read'
try {
  const result = await read(options)
} catch (er) {
  console.error(er)
}

Options

Every option is optional.

• prompt What to write to stdout before reading input.
• silent Don't echo the output as the user types it.
• replace Replace silenced characters with the supplied character value.
• timeout Number of ms to wait for user input before giving up.
• default The default value if the user enters nothing.
• edit Allow the user to edit the default value.
• terminal Treat the output as a TTY, whether it is or not.
• input Readable stream to get input data from. (default process.stdin)
• output Writable stream to write prompts to. (default: process.stdout)
• completer Autocomplete callback (see official api for details
• history History array, which will be appended to.

If silent is true, and the input is a TTY, then read will set raw mode, and read character by character.
