Generate awesome GitHub-style labels in SVG.

What is it?

If you've ever tried to recreate a GitHub label in a markdown document or issue, you'll discover you can't do it! Markdown doesn't let you style text and colors.

We can get around this by styling the text and colors in an SVG "image" and embedding that instead:

bug duplicate enhancement help wanted invalid question wontfix

The code for this is hosted on

It works just like similar badge generator sites like or

What's included

makeLabel(options) - does what it says on the tin

option type default description
option.text string 'bug' Label text - will appear centered on the label.
option.fontfamily string 'Helvetica,Arial' Text font - we just pass this directly into the SVG file.
option.fontsize number 12 Font size in px - this affects the overall size of the label.
option.fontweight number 600 Font weight as a number (over 500 is considered 'bold').
option.width number calculated Label width - calculated based on fontsize, but you can override it.
option.strokeopacity number 0.12 Opacity for the shadow outline.
option.strokewidth number calculated Shadow stroke width - also calculated but you can override it.
option.bgcolor hex #ee0701 Background color of the label.
option.fgcolor hex #333026 / #ffffff Foreground color of the label - calculated for light/dark backgrounds but you can override it.
option.strokecolor hex #273135 Stroke color for the shadow outline.

All hex colors can be passed either as 3 or 6 characters, and the '#' is optional.


server.js contains a simple microservice built on the koa.js framework.

npm run start will start the server on port 3000.
