Base webpack configuration for NoFlo component projects

This repository aims to provide a reusable WebPack configuration for NoFlo component projects, primarily aimed at CI usage.

Build setup

You need to add the following development dependencies:

• webpack
• webpack-cli
• noflo-component-loader
• noflo-runtime-headless
• noflo-runtime-postmessage

Then add a build command to your NPM scripts:

"build": "webpack --config node_modules/noflo-webpack-config/webpack.config.js",

Now you should be able to make a browser build of your components with npm run build.

Note: if you have CoffeeScript dependencies, install also the coffee-loader package.

Testing components with fbp-spec in browser

You need to add the following development dependencies:

• fbp-spec

Then add a test command to your NPM scripts:

"test:fbp-spec": "fbp-spec --address ws://localhost:3569 --command \"noflo-runtime-headless -f dist/test.js\" spec/*.yaml",

Now you should be able to run fbp-specs in a browser with npm run test:fbp-spec.

Testing components with Mocha in browser

You need to add the following development dependencies:

• chai
• karma
• karma-chai
• karma-chrome-launcher
• karma-mocha
• karma-mocha-reporter

Then add a test command to your NPM scripts:

"test:mocha": "karma start node_modules/noflo-webpack-config/karma.config.js",

Now you should be able to run Mocha tests in a browser with npm run test:mocha.

Notes:

• noflo, chai and baseDir are available globally, so no need for additional requires in your test files
• the test files should be located in spec/*.js or spec/**/*.js
