Added support for our new workdays endpoint that allows you to pull the
number of working days that occur between two dates.
In addition to the new endpoint:
* chore: upgraded dependencies.
* ci: dropped Node.js 10 because it past EOL.
* ci: swapped Node.js 15 for 16 now that it's out.
* docs: added example of new endpoint.
Added support for our latest endpoint, which calculates the workday a
given number of business days into the future from the given date for
the given country.
Also:
* perf: updated dependencies
* ci: pinned eslint to 7.2.x due to airbnb incompatibility with 7.3.x.
* ci: tweaked / improved eslint rules a bit.
* refactor: updated types to use `;` and include weekday response.
* docs: added example for new endpoint.
* feat: pull country or language by code.
This differs from the existing `search` functionality in that it allows
you to explicitly pull back a single country or language instead of
anything that matches (which could result in more items returned than
expected).
* refactor(types): add new types for the affected endpoints.
* docs(readme): update to include examples for new functionality.
* test: expand tests to include new parameters.
* feat(package): upgrade dependencies to the latest versions.
* fix(eslint): adjust configuration based on an updated dependency.
* docs(license): bump the year of the license.
* chore: Updated dependencies.
* test: Fixed a linter issue in the test suite.
* feat: Updated all requests to contain the `search` property.
* chore: Cleaned up some of the type properties order (alphabetized).
* test: Added tests to cover the search capabilities.
* docs: Added examples to the readme to cover all endpoints as well as search.
* docs: Updated the readme to cover migrating from v1 to v2.
* docs: Fixed repository links where applicable.
* chore: Bumped the minor version number.
