To run the example code from the top-level application directory,

$ node ./examples/index.js

Notes

• See RFC 3986 and Wikipedia for information regarding the URI scheme.
• This module uses the same test URIs as valid-url (a clone of a corresponding Perl package), which are based on examples from RFC 3986.

Tests

Unit

Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:

$ make test

All new feature development should have corresponding unit tests to validate correct functionality.

Test Coverage

This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

$ make test-cov

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

$ make view-cov
