Typed Path

---

Problem

Types are lost when string paths are used in typescript.
I.e. _.get, _.map, _.set, R.pluck from libraries like lodash, ramda.
It makes those methods dangerous in case of refactoring, the same as JavaScript.

Solution

Errors

With typed-path typescript can check paths and warns you about errors.

Also you can get access to the path string using $path special field. @m-abboud

Like this:

    console.log(tp<TestType>().a.b.c.d.$path); // this will output "a.b.c.d"

If you need a raw path, which is of type string[] - you can get it using $raw special field. dcbrwn

    console.log(tp<TestType>().a.b.c.d.$raw); // this will output ["a", "b", "c", "d"]

Suggestions

Also typed-path allows typescript to suggest field names for you.
