Here are some frequently asked questions.
The is function of the Validator exists essentially only for type narrowing.
In current TypeScript, Narrowing can be accomplished by using Type guards or
asserts. Unfortunately, they can only represent boolean or throw errors.
We also considered separating the is function from the Validator, but this
created unnecessary complexity.
It was a requirement that validate be able to lazily generate results, so the
interface requires two functions.
Don't forget to add a pure annotation so that users of your library will receive the appropriate tree-shaking.
It is recommended that structure be defined at the top-level of the module. This is because instantiation usually has a small overhead.
Most bundlers will mark top-level calls as having side-effects.
See example:lib for more information.
Bundle sizes for individual modules are listed in the respective documentation. This is a reference value for bundle size.
However, it should be noted that if multiple modules are used, they do not add up.
This is because each module shares a reusable module.
