A method to test a string against the routes table

[briandela]

Just wondering if there is a way in 7.5.x to check if a string would be a valid match for one of the routes.

In a location where I have access to the server object I have a string (e.g. /hello/there/hapi) and I want to see if it would match a route in that server object (e.g. if there was a /hello/there/{thing} the above string would match that (assuming that was the best match)).

Thanks.

Depending on what your handler is doing, you could call server.inject('/hello/there/hapi', function (res) { }). If it returns 2xx, then the route exists, if it returns 404, then it doesn't. Of course the handler can return 404 for other reasons too (like document doesn't exist in the database). That's why this depends on what your handler is doing.

An other way could be to call server.table() to get the array of routes:
https://github.com/hapijs/hapi/blob/v7.5.2/docs/Reference.md#servertablehost

You could then create a Call object, add the routes returned by server.table() and test your routes with the route() function:

Not directly. The above suggestions are your only real option. There used to be an internal method to do that but it's not longer available.

Thanks all.
@hueniverse We'll be moving to 8 in the near future. Is there an alternative way of doing this with v8?

I am thinking about adding this feature, hence why this issue is still open...
