Hi Reid,
This is excellent. Just experimenting and trying to get my head around it.
Not sure if I'm doing any wrong or stupid!! If I test a function that
relies on Exception handling internally as I reach 100 tests it takes
forever and eventually blows the heap.
Simple contrived example:

I used CongoMongo for my base web app with authentication
(https://github.com/xavi/noir-auth-app). When asked (a year ago) why I
didn't use Monger I said I prefer CongoMongo because it's smaller and so
probably easier to understand, and it does all I need
Congrats Reid, thanks a lot for all your work on this!
Have only been using simple-check for a little while now, but it's already
paid big dividends in production. One of the most concretely useful testing
tools I've ever used. For folks that haven't tried it, I'd absolutely
recommend taking a
Maybe one additional thing to note is that the book shows that the Clojure
web development ecosystem is a reflection of its general philosophy and
it's not about any particular framework but more focused on composing
simple components/libraries. Once you understand the basic concepts (HTTP
I would recommend this combination of libraries:
- Compojure
- lib-noir
- Enlive and Enfocus, for server-side and client-side templating
respectively (I've also used Hiccup, but I prefer Enlive/Enfocus because
with these, templates are pure HTML; I prefer them even for solo projects,

OK, took my usual approach when stuck, which is to try and turn it into a
different problem! Decided to stop trying to use handle* directly, but
rather explicitly start an nREPL server on a socket, and relay those
messages over websocket. Seems to work fine :-)
Thanks,

Yes, Reagent doesn't know about React components that don't live in React.DOM

So what you would need to do is to get hold of the component constructor,

If you are learning go with a simple approach (compojure + http-kit +

there).

IMO that would needlessly complicate an otherwise simple construct,
especially since a simple macro can endlessly customise it.

Clojure works on a chunked basis for performance reasons...THe size of a
chunk is 32 elements - thus you would actually get 32 printouts if you
supplied a collection larger than 31 elements.

Lazy sequences are realised in chunks of 32.
You can see this by running:

Long story short. You should be learning Pedestal, but the app component is
on pause at the moment. My advice is to learn pedestal-service and Om. When
Pedestal-app gets going again, learning Om will have given you a good context
for transitioning to Pedestal 100%.

Hey Andrew,
Good question. tl;dr, change your test to:

Longer explanation:
test.check's generators take two parameters, a random number generator, and an
integer 'size'. During testing, the size starts at 0, and increases up to

So I just booted up my ubuntu to check if the same happens here too. And

What I did was:

3. do an ln -s ../../subproject

wont.
Ok, finally i found it myself after days of days of digging :D

Hi,
Can I ask a newbie question about clojure performance?
What make clojure performance slow than java?, it seems clojure has the 1/4
performance compared to java in general, according to tests, some cases it
might be 1/10. the reasons I can think out are
- the byte code is not efficient
Think you.

I have seen (and I keep seeing) a ton of Java code that performs poorly.
Empirically, it's equally easy to write a slow Java app. You always need a
discerning programmer to get good performance from any language/tool.
