gulp-some

A MIT-licensed Gulp plugin for passing through all source files only if at least one returns true.

Install

npm install gulp-some --save-dev

Example

Using some with many sources

var gulp = require('gulp');
var newer = require('gulp-newer');
var some = require('gulp-some');
var ts = require('gulp-typescript');

// Compile all TypeScript files
gulp.task('ts', function() {
  // Add the some pipe to pass through all sources only if at least one source file is newer.
  // Otherwise, pass an empty stream to ts() to skip compiling pure definition files.
  return gulp.src('src/*.ts', 'types/*.d.ts')
      .pipe(newer('dist'))
      .pipe(some((i) => !i.relative.endsWith(".d.ts")))
      .pipe(ts())
      .pipe(gulp.dest('dist'));
});

API

some(check)

• check - function check if a File object needs to be piped, just as the options.check below.

some(options)

• options.check - function check if a File object needs to be piped (e.g. function(file) { return !file.relative.endsWith(".d.ts"); })

Create a transform stream that passes through all files in which at least one needs to be piped.
