d8 is a pre-processor for coverage output from deno, making it palatable for
use with c8. This enables access to istanbul's
rich set of reporting options.
deno install --allow-read --allow-write --unstable -n d8 https://x.nest.land/[email protected]/cli.ts
NOTE
c8only consumes coverage output in./coverage/tmp- This means second argument to
d8 convertshould be set to./coverage/tmp
Usage: d8
Version: v0.1.0
Description:
Adapt deno coverage output to c8/nyc/istanbul reporting
Options:

# (see c8 docs for more details)
Unfortunately, a c8 dependency uses an unsupported node.js core API and
prevents this module from being used as deno module.
