    check-files-exist

    This small promise based node module checks a given string or array of strings to contain valid file selectors. The selectors could either be relative or absolute paths or even globs.

    Syntax

    var checkFilesExist = require('check-files-exist');
     
    checkFilesExist(['files/a.js', 'files/*_c.js'], __dirname).then(function () {
      console.log('All files exist.');
    }, function (err) {
      console.log(err);
    })

    Examples

    Let's assume, we've got the following directory structure:

    + files
      -  a.js
      - b_c.js
      - d.js
    

    Each of the following calls would resolve the promise:

    checkFilesExist('files/*')
    checkFilesExist('files/**/*')
    checkFilesExist('files/a.js')
    checkFilesExist(['files/a.js', 'files/d.js'])
    checkFilesExist(['files/a.js', ['files/*_c.js']])
    checkFilesExist(['files/a.js', ['files/*_c.js', 'files/b_*']])
    checkFilesExist([['files/a.js'], ['files/*_c.js', 'files/b_*']])

    The following would reject it:

    checkFilesExist('')
    checkFilesExist('files/_*')
    checkFilesExist([])
    checkFilesExist(['files/', ''])

    Use in a build chain

    Using this module in f.e. gulp is really simsple:

     
    gulp.task('checkFilesExist', function() {
      return checkFilesExist([
          config.scripts.files,
      ]);
    });

    Working dir

    node-glob provides passing a cwd working directory string. You could easily pass a string as a second parameter to have it passed to glob:

    checkFilesExist('files/a.js', __dirname).then(...);

    Install

    npm i check-files-exist
