stdins - standard input string or buffer

process's standard input "stdin" with a string or a buffer.

Prepare

$ npm install stdins --save
  or
$ npm i stdins -S

require('stdins');
// and use global variable "stdins" or "stdinbuf".

Usage

$ echo abc | node -r stdins -e "stdins(str => console.log(str))"
  or
$ echo abc | node -r stdins -e "stdins.then(str => console.log(str), err => console.error(err))"
$ echo abc | node -r stdins -e "stdins((err, str) => console.log(str, err))"
$ echo abc | node -r stdins -e "stdinbuf(buf => console.log(buf + ''))"
$ echo abc | node -r stdins -e "stdinbuf.then(buf => console.log(buf + ''), err => console.error(err))"
$ echo abc | node -r stdins -e "stdinbuf((err, buf) => console.log(buf + '', err))"

require('stdins');

stdins(str => console.log(str));
// or
stdinbuf(buf => console.log(buf.toString()));

Quick Examples

stdins() async thunk with string

stdins is function, thunk, callable with callback.

callback's first argument receives a string.

stdins(str => console.log(str));

callback's first argument receives an error, and second argument receives a string.

stdins((err, str) => err ?
  console.error(err) :
  console.log(str));

stdins.then() async promise with string

stdins is promise, thenable.

resolved with a string.

stdins.then(
  str => console.log(str),
  err => console.error(err));

stdinbuf() async thunk with buffer

stdins is function, thunk, callable with callback.

callback's first argument receives a buffer.

stdins.buf(buf => console.log(buf.toString()));

stdinbuf(buf => console.log(buf.toString()));

callback's first argument receives an error, and second argument receives a buffer.

stdins.buf((err, buf) => err ?
  console.error(err) :
  console.log(buf.toString()));

stdinbuf((err, buf) => err ?
  console.error(err) :
  console.log(buf.toString()));

stdinbuf.then() async promise with buffer

stdins is promise, thenable.

resolved with a buffer.

stdins.buf.then(
  buf => console.log(buf.toString()),
  err => console.error(err));

stdinbuf.then(
  buf => console.log(buf.toString()),
  err => console.error(err));
