Good morning.

Good morning 'veryone

Anybody using schema? https://github.com/Prismatic/schema

@pupeno: I had a play with it and it is a rather nice lib IMHO

pupeno: i'm using schema

easier to to use then core.typed I think

mccraigmccraig: what do you think of it? nice? useful? stable?

pupeno: all of the above :simple_smile: ... i'm using it in several places :

to validate om component properties

to validate backend component configuration

and to validate api arguments

it's made change/refactoring easier and increased confidence, and i haven't (yet) found any bugs in schema itself

morning

mccraigmccraig: that sounds good. I’ll give it a try then.

mccraigmccraig: any reason to use it instead of core.typed? (I’m completely unfamiliar with either and I’m completely at home with dynamic languages anyway).

pupeno: several reasons : core.typed doesn't work on cljs, core.typed is (well, looks to be, i haven't had a serious attempt) hard to retrofit

plus, core.typed isn't really oriented towards validity checking things like http post bodies, whereas schema is a good fit for that

Interesting. Thanks.

Morning

@pupeno: my experiences are the same as Craig's

Good to know. I’ll check schema before I start writing production code.

moaning

I’ve used schema before - it’s ace. Be aware that if you use it a lot for complex nested types, over and over again, there might be a performance hit (as would make sense)

- whereas core.typed is at compile time so no overhead.

I prefer schema, myself, but did have to diagnose a problem where some naive code was using schema on a very messy structure, and then repeating that on every row of a 15000-row query...

So, who wants to start a Ldnclj snail-mailinglist with me? I figured along with gitter, irc, slack, irl and a messageboard we didn't have enough channels to communicate on. :P

@xlevus: there is already one

ahaha

nono.

Snail-mail

aaahhh

😄

as in, letters, and stamps, and bad service.

I’m in! I’m always looking for opportunities to use my wax seal.
