What is c8?

The c8 npm package is a code coverage tool for JavaScript that works with the native V8 coverage functionality built into Node.js. It collects and reports on the test coverage of your code, helping you understand which parts of your codebase are covered by tests and which are not.

What are c8's main functionalities?

Code Coverage Reporting

This command runs your Node.js script with coverage tracking, and upon completion, it outputs a coverage report. The report shows the percentage of code executed by your tests, helping you identify untested parts of your codebase.

npx c8 node script.js

Integration with Testing Frameworks

You can use c8 in conjunction with testing frameworks like Mocha. This command will run Mocha tests with coverage tracking, and then generate a coverage report.

npx c8 mocha

Custom Report Formats

c8 allows you to specify one or more reporters that determine the format of the coverage report. In this example, it generates both 'lcov' and 'text' format reports.

npx c8 --reporter=lcov --reporter=text node script.js

Check Coverage Thresholds

This feature allows you to enforce coverage thresholds. If the coverage falls below the specified percentages for lines, functions, or branches, c8 will exit with a non-zero status, which is useful for CI/CD pipelines.

npx c8 --check-coverage --lines 95 --functions 95 --branches 95 node script.js
