grunt-noflo-browser

Grunt plugin for building NoFlo projects for the browser. It also extracts possible HTML contents from graphs and creates demo files for them. It uses Webpack for building.

grunt-noflo-browser can also be used for creating single-file executable bundles of Node.js projects. This can increase start-up time, especially in constrained environments.

Getting Started

This plugin requires Grunt 1.x

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-noflo-browser --save-dev

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

grunt.loadNpmTasks('grunt-noflo-browser');

The noflo_browser task

Overview

In your project's Gruntfile, add a section named noflo_browser to the data object passed into grunt.initConfig().

grunt.initConfig({
  noflo_browser: {
    options: {
      // Task-specific options go here.
    },
    build: {
      // Target-specific file lists and/or options go here.
    },
  },
});

Options

options.graph

Type: String Default value: null

Setting this to the component name of a graph scopes the build to only include dependencies of that graph. If set to null, all available components will be included.

options.webpack

Type: Object

Webpack configuration options to use with the build.

options.ignores

Type: Array Default value: [/tv4/]

List of regular expressions matching modules to ignore in the build. Can be used to remove optional dependencies.

options.manifest

Type: Object

Custom options to pass to fbp-manifest at component discovery stage.

options.development

Type: Boolean Default value: false

Whether to build also the development dependencies.

options.debug

Type: Boolean Default value: false

Whether to enable debugging using Flowhub over postMessage transport. Requires noflo-runtime-postmessage module to be installed.

options.ide

Type: String Default value: https://app.flowhub.io

Which IDE instance to use for live-mode debugging url.

Usage Examples

A typical browser build

In this example we'll parse the package.json file, download the dependencies, and create the built file to the dist folder.

grunt.initConfig({
  noflo_browser: {
    options: {},
    build: {
      files: {
        'dist/noflo.js': ['package.json'],
      },
    }
  },
});

This generated file will provide a window.require function that can be used for loading NoFlo.
