vitest config sample

export default {
    test: {
        coverage: {
            reporter: ['text', 'json', 'html','coverage-svg'],
            provider: 'istanbul'
        }

}

Use in README.md

The SVG should be available either in the repo or on CDN in order to be shown in GitHub page.

As unpkg.com reflects the npm content, where the coverage usually is not included, it can be done by publishing either test project with coverage results or the coverage content alone.

The good example would be a test project for custom-element.

explainer

Often there is a need to generate the coverage not only for essential sources but also for complimentary code like mocks, StoryBook, etc. That impacts the total stats and do not have the interest to the consumer. The coverage-svg generates the SVG on each module and folder which you can refer individually. In this case the coverage for test-proj/coverage/src/package2 is published on

https://unpkg.com/[email protected] and the generated image is

https://unpkg.com/[email protected]/test-proj/coverage/src/package2/coverage.svg

change on release/ npm publish

The unpkg.com keeps each version of released package. You would need to update the URLs before release.
