c8 - native V8 code-coverage

Code-coverage using Node.js' build in functionality that's compatible with Istanbul's reporters.

Like nyc, c8 just magically works:

npm i c8 -g
c8 node foo.js

The above example will output coverage metrics for foo.js.

c8 report

run c8 report to regenerate reports after c8 has already been run.

Disclaimer

c8 uses bleeding edge Node.js features, make sure you're running Node.js >= 10.10.0.
