getEnvVar.boolean
currently only supports the string true
in lowercase as true, it should instead ignore the case of the text string.
Idea is to be able to apply mapping function on retrieved values. My idea is to have something like this:
const intEnv = getEnvVar("SOME_INT_ENV").map(Number.parseInt).required();
and for optional values with default
const intEnv = getEnvVar("SOME_INT_ENV").map(Number.parseInt).orDefaultValue(42);
but that breaks backwards compability. The other way could be to introduce third argument, but then you can't stack applied functions, and it looks a bit of awkward (esp. when you want to have a mapping function over a value that is required).
