@brillout/libassert

Minimalistic & simple assertions for library authors.

For example:

import { assertUsage, setProjectInfo } from @brillout/libassert;

export { hello };

setProjectInfo({
  projectName: 'Awesome Library',
});

function hello(name) {
  assertUsage(name, "Missing argument `name`.");
}

If your user calls hello() without arguments then assertUsage throws following error:

Error: [Awesome Library][Wrong Usage] Missing argument `name`.
