Create dashboards using YAML/JSON files



just-dashboard Travis Codecov

Turn this:

dashboard "Food":
  - h1 text: Food
  - h2 text: By caloric content
  - 3 columns:
    - rows:
      - h3 text: Bananas
      - pie chart: {
          "columns": [
            ["Protein", 5], ["Sugar", 10], ["Other carbs", 40], ["Fat", 1]
          ]
        }
    - rows:
      - h3 text: Tofu
      - pie chart: {
          "columns": [
            ["Protein", 30], ["Sugar", 0], ["Other carbs", 40], ["Fat", 3]
          ]
        }
    - rows:
      - h3 text: Peanut butter
      - pie chart: {
          "columns": [
            ["Protein", 20], ["Sugar", 2], ["Other carbs", 20], ["Fat", 50]
          ]
}

Into this:

To host your dashboard, you can roll your own backend, or:

  • Create a public GitHub gist with a file named dashboard.yml or dashboard.json (depending on your preferred format)
  • Access it as a shareable dashboard at: http://bottoml.in/e/{Github username}/{Gist ID}

In fact, I've created a Gist with the example above: https://gist.github.com/kantord/2973bdd4ad689642562018bb4091ffbd; thus it's accessible as a dashboard at: http://bottoml.in/e/kantord/2973bdd4ad689642562018bb4091ffbd

Don't repeat yourself

As your dashboard is just data, you can generate it instead of repeating yourself. You can do that by generating the YAML or JSON file yourself, or you can use jq queries in your YAML file.

To illustrate that, I've created two separate GitHub Gists. One with only the data:

{
  "Bananas": [["Protein", 5], ["Sugar", 10], ["Other carbs", 40], ["Fat", 1]],
  "Tofu" : [["Protein", 30], ["Sugar", 0], ["Other carbs", 40], ["Fat", 3]],
  "Peanut butter": [["Protein", 20], ["Sugar", 2], ["Other carbs", 20], ["Fat", 50]]
}

And one with a dashboard that contains a component that can fetch the data from other other gist and turn it into 3 different charts, just like in the manually created example above:

dashboard "Food":
  - h1 text: Food
  - h2 text: By caloric content
  - 3 columns:
    - attr:query: '[to_entries | .[] | {"component": "rows", "data": [
      {"component": "text", "args": {"tagName": "h3"}, "data": .key},
      {"component": "chart", "args": {"type": "pie"}, "data": {"columns": .value}}
    ]}]'
    - data: https://gist.githubusercontent.com/kantord/2b2e3b22cb70be0415a7d50c395fa411/raw/47542f8a3db0d65aeeb48e28ddfaa8feabbc72b5/nutri.json

You can see the results for yourself here: http://bottoml.in/e/kantord/aa4a30d09343f0527b8969ad0810946e

Using the same principle, you can also loads parts from your dashboard from other files, or just JSON/CSV data for specific charts.

Using your own backend

If you want to create a public dashboard, it's enough to simply link resources that you host, for example:

dashboard "Hello World":
  bar chart:
    https://my-awesome-backend.com/api/get_data

If Gists don't work for you, for example because you need to implement authentication, you'll have to host a frontend for yourself.

Install just-dashboard from npm: npm install --save just-dashboard

Here's a minimal example on using it as your project's frontend:

import { json_parser, yaml_parser } from 'just-dashboard'
import * as d3 from 'd3'

// Load data
const dashboard_yaml = ... // Load your YAML here
const dashboard = yaml_parser(dashboard_yaml)

// Create render function
const render_dashboard = json_parser(dashboard)

// Render dashboard
render_dashboard(d3.select("body"))
