Define specific target configuration.

grunt-config

Easy way to define specific target configuration.

Getting Started

This plugin requires Grunt >=0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-config --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-config');

This plugin was designed to work with Grunt 0.4.x. If you're still using grunt v0.3.x it's strongly recommended that you upgrade.

Config task

Run this task with the grunt config command.

Task targets and options may be specified according to the grunt Configuring tasks guide.

Options

variables

Type: Object

This option is used to define the variables to be exported in grunt.config object.

options: {
  variables: {
    'foo': 'bar'
  }
}

silent

Type: Boolean Default: false

If set to true, removes the output from stdout.

Usage Examples

config: {
  dev: {
    options: {
      variables: {
        'environment': 'development'
      }
    }
  },
  prod: {
    options: {
      variables: {
        'environment': 'production'
      }
    }
  }
}

Default & Shared variables

config: {
  options: {
    variables: {
        'app': 'Demo',
        'environment': 'default'
    }
  },
  dev: {
    options: {
      variables: {
        'environment': 'development'
      }
    }
  },
  prod: {
    options: {
      variables: {
        'environment': 'production'
      }
    }
  }
}

Environment variables in source (with grunt-replace)

File build/environment.txt:

@@app - @@environment

Gruntfile:

config: {
  options: {
    variables: {
        'app': 'Demo'
    }
  },
  dev: {
    options: {
      variables: {
        'environment': 'development'
      }
    }
  },
  prod: {
    options: {
      variables: {
        'environment': 'production'
      }
    }
  }
},

replace: {
  dist: {
    options: {
      variables: {
        'app': '<%= grunt.config.get("app") %>',
        'environment': '<%= grunt.config.get("environment") %>'
      },
      force: true
    },
    files: [
      {expand: true, flatten: true, src: ['build/environment.txt'], dest: 'public/'}
    ]
  }
}

// development
grunt.registerTask('dev', ['config:dev', 'replace']);

// production
grunt.registerTask('prod', ['config:prod', 'replace']);

Handlebars environment partials (with assemble)

Gruntfile:

config: {
  dev: {
    options: {
      variables: {
        'partials': ['assets/partials/dev/*.hbs']
      }
    }
  },
  dist: {
    options: {
      variables: {
        'partials': ['assets/partials/dist/*.hbs']
      }
    }
  }
},

assemble: {
  dist: {
    options: {
      partials: '<%= grunt.config.get("partials") %>',
      ext: '.html'
    },
    files: [
      {expand: true, cwd: 'assets/templates', src: ['**/*.hbs'], dest: 'tmp/templates'}
    ]
  }
}

// development
grunt.registerTask('dev', ['config:dev', 'assemble']);

// production
grunt.registerTask('prod', ['config:prod', 'assemble']);

Dynamic options (with grunt-contrib-concat)

Gruntfile:

config: {
  dev: {
    options: {
      variables: {
        'concatOptions': {
          banner: '(function dev () {',
          footer: '}());'
        }
      }
    }
  },
  prod: {
    options: {
      variables: {
        'concatOptions': {
          banner: '(function prod () {',
          footer: '}());'
        }
      }
    }
  }
},

concat: {
  dist: {
    options: {
      process: function (src, filepath) {
        var concatOptions = grunt.config.get('concatOptions');
        return concatOptions.banner + '\n' + src +
          concatOptions.footer + '\n';
      }
    },
    files: [
      {expand: true, flatten: true, src: ['test/fixtures/concat.txt'], dest: 'tmp/'}
    ]
  }
}

// development
grunt.registerTask('dev', ['config:dev', 'concat']);

// production
grunt.registerTask('prod', ['config:prod', 'concat']);

Gruntfile (using grunt templates):

config: {
  dev: {
    options: {
      variables: {
        'concatOptions': {
          banner: '(function dev () {',
          footer: '}());'
        }
      }
    }
  },
  prod: {
    options: {
      variables: {
        'concatOptions': {
          banner: '(function prod () {',
          footer: '}());'
        }
      }
    }
  }
},

concat: {
  dist: {
    options: {
      banner: '<%= grunt.config.get("concatOptions").banner %>',
      footer: '<%= grunt.config.get("concatOptions").footer %>'
    },
    files: [
      {expand: true, flatten: true, src: ['test/fixtures/concat.txt'], dest: 'tmp/'}
    ]
  }
}

// development
grunt.registerTask('dev', ['config:dev', 'concat']);

// production
grunt.registerTask('prod', ['config:prod', 'concat']);

Prevent stdout in production environment

Gruntfile:

config: {
  dev: {
    options: {
      variables: {
        'environment': 'development'
      }
    }
  },
  prod: {
    silent: true,
    options: {
      variables: {
        'environment': 'production'
      }
    }
  }
}
