vinyl-filter-by-file

Filter a vinyl stream (like gulp’s) based on .gitignore-like files.

Install this module using npm:

npm install --save-dev vinyl-filter-by-file

Usage with gulp

This plugin can be used to filter a stream in gulp:

const gulp = require('gulp');
const ignorefilter = require('vinyl-filter-by-file');

gulp.task('staticassets', () =>
    gulp.src('**', {read: false})
        .pipe(ignorefilter())
        .pipe(gulp.dest('dist'))
);

Options

The plugin exports one function, which returns a stream.Duplex that can be piped into a vinyl stream.Readable. The function takes an options object as only parameter. The options are:

name	description	type	default
filename	name of ignore files	string or array of strings	'.ignore'
maxParent	highest folder to traverse up to when looking for ignore files. Paths are resolved against process.cwd()	path or a function vinylobject => path	file => file.base
excludeIgnoreFile	whether to filter the ignore files from the stream	boolean	true

Example with Options

const gulp = require('gulp');
const ignorefilter = require('vinyl-filter-by-file');

gulp.task('staticassets', () =>
    gulp.src('**', {read: false})
        .pipe(ignorefilter({
            filename: '.gitignore',
            excludeIgnoreFile: false,
            maxParent: '.'
        }))
        .pipe(gulp.dest('dist'))

If ./.gitignore looks for example like this:

/node_modules/
/dist/

the resulting stream will for example include src/index.js, .gitignore, but not node_modules/vinyl-filter-by-file/build/index.js.
