Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

Cumul.io dashboard SDK

This is a JavaScript library for generating dashboard definitions for the Cumul.io platform

This library is in alpha state

This is an alpha release. Breaking changes and renaming is expected in future releases. Very much work in progress.

Cumul.io Dashboard SDK

This SDK allows you to programatically generate dashboards for use in the Cumul.io platform. The SDK abstracts away a lot of complexity and enables you to build interactive, multi-tenant & multi-lingual, multi-device dashboards with code just as if they would have been created using the UI.

Why? Cumul.io is API-first and a heavy believer of powerful, convenient API's. Being able to quickly generate interactive dashboards with just a few lines of code is extremely powerful. It allows you to do things like:

  • Context-aware dashboards: Show your users a dashboard with information that is relevant for them at that specific time, using their specific situation and any other context.
  • In-platform dashboard generator: Allow your users to create dashboards in a playground in your platform. This can be via a UI, a form, a stepper, ... The input from these elements can then be used to generate a dashboard 'on-the-fly' for your users to digest.
  • Exception management dashboards: Only show and or highlight information that crossed certain thresholds.
  • Change/update dashboards in batch: Did your organization theme change and you do not want to adapt all dashboards manually one by one? Use this SDK to load the existing dashboards, adapt them and update them using Cumul.io's core API.
  • ... and so much more

Installation

If you use npm, npm install @cumul.io/dashboard-sdk or yarn yarn install @cumul.io/dashboard-sdk.

This SDK is written using ES6 modules. To import this SDK into an ES2015 application, import everything into a namespace (here, cio):

import * as cio from "@cumul.io/dashboard-sdk";

In Node:

const cio = require("@cumul.io/dashboard-sdk");

Entities

This SDK uses 6 entities (classes) for building dashboards:

  • Dashboard: the dashboard itself

  • Item: A chart, filter item, text, image, video or spacer.

  • Column: A data column used to specify what data is used in an item or filter

  • Filter: A filter is used to filter the data used in a dashboard or in an item. Can be used on dashboard or item level.

  • Parameter: A parameter is often used in multi-tenant dashboards to adapt filters or the dashboard itself to the parameter value supplied.

  • Theme: A theme can be used to style a dashboard or an item. Can be used on dashboard or item level.

What you can do with these entities is described in the following sections.

Dashboard

Create a new empty dashboard

const dashboard = new cio.Dashboard();

Use an existing dashboard definition retrieved via Cumul.io's API

const dashboard = new cio.Dashboard(definition);

Dashboard name Get name:

const nameI18n = dashboard.getName();

Set name:

dashboard.setName('On the fly generated dashboard'); // Sets the name to the dashboards default language
dashboard.setName('On the fly generated dashboard', 'en'); // Sets english name of the dashboard
dashboard.setName({
  en: 'On the fly generated dashboard',
  fr: 'Dashboard généré à la volée'
});  // Sets the full localized name of the dashboard

Set description Get description:

const descriptionI18n = dashboard.getDescription();

Set description:

dashboard.setDescription('This is an example of an SDK generated dashboard'); // Sets the description to the dashboards default language
dashboard.setDescription('This is an example of an SDK generated dashboard', 'en'); // Sets english description of the dashboard
dashboard.setDescription({
  en: 'This is an example of an SDK generated dashboard.',
  fr: 'Ceci est un dashboard généré par un SDK.'
});  // Sets the full localized description of the dashboard

Screen modes Get screen modes:

const screenModes = dashboard.getScreenModes();

Set screen modes in sync:

dashboard.setSyncScreenModes(true);

Desync screen modes:

dashboard.setSyncScreenModes(false);

Add a screen mode:

dashboard.addScreenMode('mobile'); // adds an empty mobile screen mode (if screen modes are not synced)
dashboard.addScreenMode('tablet', 'desktop'); // adds a tablet screen mode (based on the desktop screen mode)

Remove a screen mode:

dashboard.removeScreenMode('tablet');

Columns A dashboard screen mode consists of columns and rows, for positioning of its items. These can differ across screen modes. Get columns:

const dashboardColumns = dashboard.getColumns(); // Retrieves number of columns for abitrary first screen mode
const mobileColumns = dashboard.getColumns('mobile'); // Retrieves number of columns for mobile mode

Set columns:

dashboard.setColumns('24'); // Sets number of columns to 24 for all screen modes
dashboard.setColumns('6', 'mobile'); // Sets number of columns to 6 for mobile screen mode

RowHeight A dashboard screen mode consists of columns and rows, for positioning of its items. These can differ across screen modes. Get row height:

const dashboardRowHeight = dashboard.getRowHeight(); // Retrieves number of columns for abitrary first screen mode
const mobileRowHeight = dashboard.getRowHeight('mobile'); // Retrieves number of columns for mobile mode

Set row height:

dashboard.setRowHeight('16'); // Sets row height to 16px for all screen modes
dashboard.setRowHeight('24', 'mobile'); // Sets row height to 24px for mobile screen mode

Timezone Get dashboard timezone:

const dashboardTimezone = dashboard.getTimezone();

Set dashboard timezone:

dashboard.setTimezone('Etc/GMT+11');

Manage filters Get dashboard filters:

const dashboardFilters = dashboard.getFilters();

Add filter instance to a dashboard, see Filter how to create one:

dashboard.addFilter(filter); // adds the filter to all screenmodes
dashboard.addFilter(filter, 'tablet'); // adds the filter only to screenmode 'tablet'

Remove filter from a dashboard, you can use the filter id or the filter instance:

dashboard.removeFilter(filterId); // removes the filter using the filter id
dashboard.removeFilter(filter); // removes the filter using the filter instance

Manage parameters List all dashboard parameters instances:

const dashboardParameters = dashboard.getParameters();

Add a parameter to a dashboard, see Parameter how to create one:

const dashboard.addParameter(parameter);

Remove a parameter from a dashboard:

dashboard.removeParameter(parameterName); // removes a parameter based on it's name
dashboard.removeParameter(parameter); // removes a parameter using the instance

Export JSON definition To export the json definition for creation with Cumul.io's API or integration Cumul.io's Integration API:

const json = dashboard.toJSON();

You can then use this json object to create a dashboard with Cumul.io's API OR just use the contents and integrate the dashboard in a webpage.

Item

Create a new chart: eg.

const barChart = new cio.BarChart();

Check the list of items for all available charts.

Set title Use a string:

barChart.setTitle('My bar chart');

Use a localized object:

barChart.setTitle({
  en: 'My bar chart',
  fr: 'Ma graphique à barres'
});

Add data

barChart
  .setData('measure', measureColumn, { format:  '.f2', aggregation:  'median' })
  .setData('category', categoryColumn, { label: { en: 'category' } });

Check the Column section how to create a column definition. Check the list of items for data slot possibilities in a chart. When setting data you can supply optional settings such as:

  • format: The format you wish to use in case of numeric or datetime data.
  • aggregation: The aggregation function you wish to use in case of numeric data. Possibilities are: sum, min, max, median, (TO DO supply all info)
  • label: an internationalized string. The label will be used in tooltips when hovering the cursor over a chart.
  • level: Numeric. The level of a datetime column (1 to 9: year to millisecond) or of a hierarchy column.

Set an option

barChart
  .setOption('categories.colored', true)
  .setOption('display.title', false);

Check the list of items for all possibilities in a chart.

Add to a dashboard From the dashboard:

dashboard.addItem(barChart);

From the item:

barChart.appendTo(dashboard);

Retrieve the dashboard the item was linked to

barChart.getDashboard();

This returns the dashboard instance linked to the item. This is very useful for chaining.

Set Size Set width & height (in columns & rows):

barChart.setSize({width: 24, height:20}); // if screen modes are synced, sets the size in all screen modes

Set width & height (in columns & rows) in a specific screen modes:

barChart
  .setSize({width: 16, height:16}, 'mobile')
  .setSize({width: 24, height:20}, 'tablet');

You can also only set width or height:

barChart
  .setSize({width: 24}, 'tablet')
  .setSize({height: 20}, 'tablet');

Set Position Set width & height (in columns & rows):

barChart.setPosition({row: 0, column: 12}); // if screen modes are synced, sets the size in all screen modes

Set width & height (in columns & rows) in a specific screen modes:

barChart
  .setPosition({row: 0, column: 12}, 'mobile')
  .setPosition({row: 12, column: 12}, 'tablet');

You can also only set width or height:

barChart
  .setPosition({row: 0}, 'tablet')
  .setPosition({column: 12}, 'tablet');
