Power Calculator

This is a Vuejs component to help decide how long you should run your experiment.

External Dependencies

Currently the graph works with D3 and C3. You will have to add those libraries to your project in case you want the graph.

Getting Started

Instalation

Then you can run $ yarn install.

When you want to build the component you will use $ yarn build.

When you want to develop, rollup has a watch flag, use $ yarn watch.

You can change rollup.config.js if the current setup doesn't suit your needs.

We are creating a js and css output files. You need to add both to your project.

How to use:

After running rollup, you will have a vuejs component you can add to your vuejs application.

Simple example would be:

let { powerCalculator, store } = require('powercalculator');

const storeInstance = new Vuex.Store(store)

new Vue(Object.assign({
    store: storeInstance,
    el: '.power-calculator',
}, powerCalculator));

Please note that the module will actually have 2 different properties:

component
store

In the example above we are just using the component to create a vue instance. It could be used with Vue.component as well.

You can create the instance of vuex with the store, merge it with yours.

Updating store from start

While we do have an action for testing to easily manipulate the store ('test:reset'), I'd recommend manipulating the store object before creating the vuex instance or creating your own actions.

Listening to store changes

I'd recommend using Vuex Plugins for this.

Some of the important actions of powercalculator store

action	description
init:calculator	Called when the component is mounted. starts calculations and deal with needed logic
field:change	Most important action. Dispatched whenever an input field change. This is the root of all the logic behind most of the mutations will happen.
update:proptocalculate	Triggers the calculation of the highlighted block

Dev Server

You can run $ yarn serve to run a development server which points to localhost:5000. It will load the index.html file which points to the files in the dist folder. You will need to run $ yarn watch in a different process to develop.

Tests

Due to the complexity of the tool we have a few different options of testing.

yarn test: Run all tests - test the mathematical functions, runs eslint and test the store updates
yarn vue-check: runs eslint and test the store updates (we are unlikely to change the mathematical functions as often as the rest)
yarn store: test the store updates
yarn eslint: runs eslint
