gulp-depcheck adds depcheck support to Gulp.

$ npm install gulp-depcheck

First you need to add gulp-depcheck to your project.

const depcheck = require('gulp-depcheck');

Then, you can use the depcheck funtion to define Gulp tasks.

gulp.task('depcheck', depcheck());

You may want to exclude some directories from being checked, e.g. the test directory. To exclude a directory, provide its name using the ignoreDirs property.

gulp.task('depcheck', depcheck({
  ignoreDirs: [ 'test' ]
}));

Additionally, if you want to exclude packages from being checked, provide their names using the ignoreMatches property. Please note that you may use glob patterns here, e.g. to exclude all packages whose names start with eslint-config-.

gulp.task('depcheck', depcheck({
  ignoreMatches: [ 'eslint-config-*' ]
}));

By default, gulp-depcheck fails on any issue it finds. From time to time you might want to adjust this, e.g. to allow unused packages in the devDependencies section of your package.json file, or to only report packages that are missing from your package.json file.

To do so, there are a few options you may hand over to the depcheck function to configure things.

• Set dependencies to false if you don't want to be notified on unused packages in the dependencies section.
• Set devDependencies to false if you don't want to be notified on unused packages in the devDependencies section.
• Set missing to false if you don't want to be notified on used packages that are missing from the package.json file.

Moreover, gulp-depcheck fails if it has problems to read files or directories. To adjust this, again there are a few options you may hand over to the depcheck function.

• Set invalidFiles to false if you don't want to be notified on files that can not be accessed or parsed.
• Set invalidDirs to false if you don't want to be notiied on directories that can not be accessed.

Moreover, gulp-depcheck supports all options of depcheck. For more details, see its documentation.

If you want to configure the version of depcheck to use explicitly provide a reference to it using the depcheck property.

Additionally, you are allowed to set a default value for the directories to ignore. For that use the ignoreDirsDefault property and hand over the names of the directories to ignore as an array. The default value is ['node_modules', 'bower_components'].

To build this module use roboter.
