Dynamic Badge Formatter

Format Shields Dynamic Badges to look consistent using formatters for metrics, versions, stars and more.

Dynamic Badge Formatter works alongside shields.io using Endpoint Badges with a Runkit Endpoint.

⚡ How to use

The easiest way to get started is to try out the demo site!

Advanced steps

Choose a JSON, XML, or YAML data URL to extract data from.
Create a query using a JSONPath (for JSON or YAML) or XPath (for XML) expression.
Set the url and query parameters at the endpoint https://dynamic-badge-formatter-ynrxn78r2oye.runkit.sh/json, using /json for JSON, /xml for XML, and /yaml for YAML.
Set additional customizations as query parameters, such as the color, label, labelColor, logo, etc., and specify a formatter to use (see below).
URL Encode the new endpoint URL and append it after https://img.shields.io/endpoint?url=. You can also do this by pasting the URL at shields.io/endpoint.

Example

The following is a JSON API I want to use for displaying data. I want to display the stars but formatted as a metric (eg. "3.2k" instead of "3227"). To extract the star count from the JSON, I will use the query $.stars.

// https://api.github-star-counter.workers.dev/user/DenverCoder1
{
  "stars": 3227,
  "forks": 1207
}

To create the Runkit URL, pass the query, url, and additional parameters to the endpoint. In this example, I set formatter to metric, label to stars, color to green, and logo to github.

https://dynamic-badge-formatter-ynrxn78r2oye.runkit.sh/json?query=$.stars&url=https://api.github-star-counter.workers.dev/user/DenverCoder1&formatter=metric&label=stars&color=green&logo=github

Using the customizer at https://shields.io/endpoint, I can turn this endpoint into a badge.

https://img.shields.io/endpoint?url=https%3A%2F%2Fdynamic-badge-formatter-ynrxn78r2oye.runkit.sh%2Fjson%3Fquery%3D%24.stars%26url%3Dhttps%3A%2F%2Fapi.github-star-counter.workers.dev%2Fuser%2FDenverCoder1%26formatter%3Dmetric%26label%3Dstars%26color%3Dgreen%26logo%3Dgithub

Result:
