Documentation

issue-dashboard is a framework for creating dashboards from user data on GitHub, utilizing GitHub Actions and GitHub Pages.

You can define the data to collect out of GitHub -- using issue queries or arbitrary scripts -- and this tool will generate dashboards in HTML, that can be published to GitHub Pages, or Markdown, that can be published as a file in a repository or a comment in an issue.

Currently, this tool only supports instantaneous data -- for example: how many issues with a certain label are open right now, or how many pull requests are currently open that were created within the last week. It does not support time series, meaning you cannot plot a graph of the number of open issues per day.

Overview

A dashboard has one or more sections, which are logical divisions and serve as collections of widgets that display data. A widget is one of:

String widget

A string widget simply displays a string. The data could be static, or the result of a JavaScript execution. A string widget has a text value, and an optional title, color and url.

Number widget

A number widget simply displays a numeric value. Like string widgets, the data could be static or the result of a JavaScript expression. But since only numbers are supported, instead of free-form strings, number widgets may be rendered smaller to save space in display.

In addition, the data source could be a GitHub issue query, in which case the number of results for the query will be displayed, and the widget will link to the query itself for more information.

A number widget has an issue_query or a numeric value, and an optional title, color and url.

Graph widget

A graph widget displays a bar chart of multiple different numeric values. Like a number widget, the data source for the values could be a static number, the result of executed JavaScript, or the number of matching results of a GitHub issue query.

A graph widget has elements, and an optional title. Each element has an issue_query or a numeric value, and an optional title, color and url.

Table widget

A table widget displays tabular data containing strings or numbers. A table contains an optional header row and multiple element rows, each row containing cells. Each cell may be a static string or the result of a Javascript expression.

In addition, the data source could be a GitHub issue query, in which case the table will contain the results of the query, and each row will link to the issue itself.

A table widget has an issue_query or elements, and an optional title and header. Each element is an array of rows. Each row has a string value and an optional align, color and url.

Installation

This dashboard tool is an action meant to be used in a GitHub Actions workflow. You should provide your input in your workflow, and it will produce HTML or Markdown. You can then either upload the result to GitHub Pages, or update an issue or file in the repository.

For example, to run this hourly (on the hour) and upload the results to GitHub Pages:

name: Build Dashboard

on:
  schedule:
  - cron: 0 * * * *

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Check out repository
      uses: actions/checkout@v2
    - name: Check out GitHub Pages branch
      uses: actions/checkout@v2
      with:
        ref: 'gh-pages'
        path: 'out'

    - name: 'Generate Dashboard'
      uses: ethomson/issue-dashboard@v1
      with:
        config: |
          title: 'Dashboard'
          output:
            format: html
            filename: 'out/dashboard.html'
          sections:
          - title: 'Pull Requests'
            widgets:
            - type: 'table'
              title: 'New Pull Requests (This Week)'
              issue_query: 'repo:libgit2/libgit2 is:open is:issue created:>{{ date("-7 days") }} sort:created-asc'
        token: ${{ github.token }}

    - name: Publish Documentation
      run: |
        git add .
        git config user.name 'Dashboard User'
        git config user.email 'nobody@nowhere'
        git commit -m 'Documentation update' --allow-empty
        git push origin gh-pages
      working-directory: out

Configuration

Configuration is specified by YAML or JSON. At the top-level, the dashboard must have an output.format of either html or markdown, and an output.filename that will be written with the dashboard contents. The dashboard should have a title and description that will be shown on the dashboard.

One or more sections can be defined, each with their own title and description. A section acts as a container for widgets that will display dashboard data.

String widgets

A string widget will simply display a textual value. An example of a dashboard with a single section that contains two string widgets:

This dashboard has a single section ('Memorable quotes') that contains two string widgets. Widgets can have titles, values, colors and URLs. The data is strictly static, it does not use a script to produce the values.

output:
  format: html
  filename: dashboard.html

sections:
- title: 'Memorable quotes'
  description: 'Some notable quotations'
  widgets:
  - type: 'string'
    title: 'Ernest Hemingway'
    value: 'The way to make people trustworthy is to trust them.'
    color: 'red'
  - type: 'string'
    title: 'Joshua from War Games'
    value: 'The only way to win is not to play.'
    color: 'black'

Number widgets

A number widget will simply display an integer or floating point number. An example of a dashboard with two sections, each with three number widgets:

This dashboard has a title ('Conversions') and a description. It has two sections ('Metric to US' and 'US to metric'), each with three number widgets. Widgets can have titles, values, colors and URLs. The data is strictly static, it does not use GitHub issue queries or scripts to produce the values.

# The title and description of the overall dashboard; these will be
# displayed at the top of the file.
title: 'Conversions'
description: 'Some handy metric to US conversions.'

# The name of the file that will be output, and the type of output.
# 'format' may be 'markdown' or 'html'
output:
  format: html
  filename: dashboard.html

sections:

# The first section is metric to US conversions
- title: 'Metric to US'
  description: 'Distance, mass and volume; metric to US.'
  widgets:
  - type: number
    value: '1.61'
    title: 'Kilometers in a mile'
    url: 'https://www.google.com/search?q=km+to+miles'
    color: 'blue'
  - type: number
    value: '0.454'
    title: 'Kilograms in a pound'
    color: 'red'
  - type: number
    value: '1.06'
    title: 'Liters in a quart'
    color: 'green'

# The section section is US to metric conversions
- title: 'US to metric'
  description: 'Distance, mass and volume; US to metric.'
  widgets:
  - type: number
    value: '0.621'
    title: 'Miles in a kilometer'
    url: 'https://www.google.com/search?q=miles+to+km'
    color: 'blue'
  - type: number
    value: '2.20'
    title: 'Pounds in a kilogram'
    color: 'red'
  - type: number
    value: '0.946'
    title: 'Quarts in a liter'
    color: 'green'

Graph widgets

A graph widget will display a bar chart of multiple numeric values. An example of a dashboard with a single section containing a graph widget with 3 elements:

This dashboard a single section ('Pizza preferences') with a graph widget. The graph widget has a title 'Pizza variety' and four elements showing that there is broad support for all pizza varieties except New Haven style.

output:
  format: html
  filename: dashboard.html

sections:
- title: 'Pizza preferences'
  description: 'Type of pizza preferred by respondents.'
  widgets:
  - type: graph
    title: Pizza variety
    elements:
    - title: New York
      value: 18
      color: green
    - title: Chicago
      value: 16
    - title: Neopolitan
      value: 15
    - title: 'New Haven'
      value: 1
      color: red

The elements themselves behave as number widgets, and the query, expression and syntax described below applies to the numeric value elements of graph widgets.

Table widgets

A table widget will display a table of multiple string values. An example of a dashboard with a single section containing a table widget with a header and 6 elements:

This dashboard a single section ('Important Dates') with a table widget. The table widget has a title 'Historic US dates' and two headers ('Date' and 'Description'). There are 6 elements, each with two cells. The first element uses strings for simplicity. The second element shows static data as a value with additional attributes.

output:
  format: html
  filename: dashboard.html

sections:
- title: 'Important Dates'
  description: 'Important dates throughout history.'
  widgets:
  - type: 'table'
    title: 'Historic US dates'
    headers:
    - 'Date'
    - 'Description'
    elements:
    - [ '1775-04-19', 'Battles of Lexington and Concord' ]
    - - value: '1776-07-04'
        color: 'blue'
        url: 'https://en.wikipedia.org/wiki/Independence_Day_(United_States)'
      - value: 'Independence Day'
        color: 'red'
        url: 'https://en.wikipedia.org/wiki/Independence_Day_(United_States)'
    - - value: '1929-10-24'
        color: 'black'
      - value: 'Black Thursday; the stock market crash of {{ 1928 + 1 }}'
        color: 'black'
    - [ '1933-12-05', 'Repeal of prohibition' ]
    - [ '1973-01-22', 'Roe v Wade' ]
    - [ '2015-06-26', 'Obergefell v Hodges' ]

Querying GitHub issues and pull requests

Instead of providing a static numeric value for number widgets and graph elements, you can provide an issue_query that will be run against GitHub, using their query syntax. The number of results will be displayed as the value. If a url is not provided, it will be provided as a link to the query on github.com.

For example, the issue query repo:libgit2/libgit2 is:pr is:open will query the number of pull requests in the open state in the libgit2/libgit2 repository. The dashboard widget will show the number of results, and if no url is specified, the widget will link to the corresponding query on github.com for full results.

widgets:
- type: number
  issue_query: 'repo:libgit2/libgit2 is:pr is:open'
  title: 'Open pull requests'
  color: 'blue'

Similarly, instead of providing a list of values for a table widget, you can provide an issue_query that will be run against GitHub, using their query syntax. The results will be displayed as the rows. By default the issue or pull request number and title will be shown.

For example, the query repo:libgit2/libgit2 is:pr is:open will query the pull requests in the open state in the libgit2/libgit2 repository. The table widget will show each result, one per line. The table cell will link to the corresponding issue on github.com.

widgets:
- type: table
  issue_query: 'repo:libgit2/libgit2 is:pr is:open'
  title: 'Open pull requests'

Using JavaScript expressions

You can use JavaScript expressions within the fields to compute them by surrounding the script within double curly-braces ({{ and }}).

For example, this number widget will have a value of the result of the computation of 42 * 2.

widgets:
- type: number
  value: '{{ 42 * 2 }}'
  title: 'Simple arithmetic'
  color: 'blue'

The value is calculated first, and available to other fields. This number widget will have a color of red if the value is below 10, or green otherwise.

widgets:
- type: number
  value: '12'
  title: 'Simple arithmetic'
  color: '{{ value < 10 ? "red" : "green" }}'

Some helper functions are available, including date manipulation functions, since many GitHub issue queries take dates and times.

widgets:
- type: number
  issue_query: 'repo:libgit2/libgit2 is:open created:<{{ date("-1 month") }}'
  title: 'Issues and PRs older than 1 month'

For more information, see Data available to scripts.

Running function to produce data

For more complicated computations, you can provide a script that will be evaluated in an async context. The return value of the function will be used as the numeric value. Some data is provided, including the github context, which is an instance of the Octokit API.

This widget will search open pull requests in the libgit2/libgit2 repo that are older than 1 day.

widgets:
- type: number
  script: |
    const results = await github.search.issuesAndPullRequests({
      q: `repo:libgit2/libgit2 is:pr is:open created:<${date('-1 day')}`
    })
    return results.data.total_count

You can also return an object, with a value property set to the numeric value for the widget. The object may also include the title, url and color properties. These will override the properties set in the YAML configuration.

widgets:
- type: number
  script: |
    const repo = 'libgit2/libgit2'
    const results = await github.search.issuesAndPullRequests({
      q: `repo:${repo} is:pr is:open created:<${date('-1 day')}`
    })
    const count = results.data.total_count
    const title = 'PRs older than 1 day'
    const color = (count > 10) ? 'red' : 'green'
    return { value: count, title: title, color: color }

Data available to scripts

Scripts will be run with some additional data available:

github: An instance of the Octokit API for interacting with GitHub REST APIs. This will be authenticated with the GITHUB_TOKEN from the GitHub Actions instance creating this dashboard.

userdata: An object that is initially empty, and that you can use to store data between script invocations. See "Storing user data for scripts", below.

value is available to the title, url and color expressions, and will be populated with the value of the widget.

item is available to the value expressions of table fields that are generated from queries, and will be populated with the returned item from the query.

And additional helper functions:

date(): A function to produce a date in YYYY-MM-DD format. Without arguments, it will return the current date in UTC. You can specify a date or full timestamp as the argument, and include date or time adjustments, specified below.

datetime(): A function to produce a date and time in YYYY-MM-DDThh:mm:ssZ format. Without arguments, it will return the current date and time in UTC. You can provide a date or full timestamp as the argument, and include date or time adjustments as specified below.

time(): A function to produce a time in hh:mm:ss format. Without arguments, it will return the current time in UTC. You can provide a time or full timestamp as the argument, and include date or time adjustments as specified below.

Time and date adjustments:

Adjustment strings can be provided to the date functions so that you can calculate dates and times in the past or future. Adjustments are given as + or - an integer number of units (days, hours, etc.) Additionally, adjustments may be given as + or - a number of hours, minutes and seconds in hh:mm:ss format.

For example:

date('2018-12-31T11:33:44Z'): will return just the date portion of the timestamp given. This will return 2018-12-31.

date('2018-11-25 + 1 month'): will return the date one month after 2018-11-25. This will return 2018-12-25.

date('-1 month'): will return the date in YY-MM-DD as of one month ago. If today's date is 2020-04-15 then this will return 2020-03-15.

datetime('-1 year-1 month-1 day+1 hour+1 minute+1 second'): will return the date and time in YY-MM-DDThh:mm:ssZ format as of one year, one month and one day ago. If today's date and time is 2020-04-15T13:46:14 then this will return 2019-03-14T12:45:13.

time('-01:02:03'): will return the time in hh:mm:ss format as of one hour, 2 minutes and 3 seconds ago. If the current time is 12:45:13, then this will return 11:43:10.

Storing user data for scripts

The userdata object is available for scripts to store data between script invocations. For example, the expression userdata.num = 2 will be executed for the first widget, which will have a value of 2. The userdata object will be available for the subsequent widget's expression, so it will evaluate to a value of 4.

widgets:
- type: number
  value: '{{ userdata.num = 2 }}'
- type: number
  value: '{{ userdata.num * 2 }}'

Setup and shutdown scripts

A top-level setup script can be defined, which will be executed at the beginning of dashboard execution. This may be useful to set up properties or define functions in the userdata object for subsequent scripts. A top-level shutdown script can be defined, which will be executed after the dashboard is built.

title: 'Dashboard'
output:
  format: html
  filename: dashboard.html
setup: |
  userdata.color_func = function(num) {
    if (num < 10) return 'green'
    if (num > 50) return 'blue'
    return 'yellow'
  }
sections:
- title: 'Pull requests'
  widgets:
  - type: number
    issue_query: 'repo:libgit2/libgit2 is:pr is:open'
    color: '{{ userdata.color_func(value) }}'

Colors

Currently supported colors are:

black
red
yellow
green
blue

Configuration reference

Configuration is specified by YAML or JSON; the general structure is defined below. Syntactically:

Dot-notation (a.b) is used to denote properties on maps. For example:

output.format refers to a property format on the output map, which would be specified in YAML as:
```
output:
  format: 'markdown'
```
Array notation (a[n]) is used to denote sequences. This may be combined with dot-notation, for a sequence of maps, or array notation, for a sequence of sequences. For example:

sections[i].title refers to a property title on an element in the sections sequence, which would be specified in YAML as:
```
sections:
- title: 'The title of the first section'
- title: 'The title of the second sequence'
```
A more complex example, sections[i].widgets[j].elements[k][m].value refers to the value property on an element in the multi-dimensional sequence elements, on the widgets sequence, itself a part of the sections sequence, which would be specified in YAML as:
```
sections:
-  widgets:
   - elements:
     - - value: 'First cell in the first row'
       - value: 'Second cell in the first row' 
       - value: 'Third cell in the first row'
     - - value: 'First cell in the second row'
       - value: 'Second cell in the second row' 
       - value: 'Third cell in the second row'
```
