wait-stream

Simple wait module for streams3 in node.

Set a delay in a pipeline using setTimeout. Works well with Gulp.

Uses through2 as opposed to node core's stream module. See this excellent article by @rvagg for more:

Why I don't use Node's core 'stream' module

Usage

wait(timeout[, options])

timeout

{number} The delay in ms to pass to setTimeout.

options

once

{boolean} The delay will only happen for the first chunk to enter the stream; all other chunks will pass through immediately.

Example

const wait = require('wait-stream');

pipeline
    .pipe(wait(500)) // wait 500 ms before continuing
    .pipe(nextTask);

Example using Gulp

Added because of the rising popularity of Gulp.

const gulp = require('gulp');
const wait = require('wait-stream');

gulp.task('default', build);

function build() {
  gulp.src('source/**')
      .pipe(build)               // could be anything
      .pipe(wait(500))           // wait 500 ms before continuing
      .pipe(gulp.dest('dest'));
}
