This week we'll extend our TodoMVC implementation in the Exercise. First,
though, various links from around the Elm ecosystem.
In this week's link dump, we'll have a look at a list of must-see links per the
elm-lang slack channel and found via the
Here's a link to Elm's documentation site, if you haven't seen it yet. The next
few links are from there, as well.
equivalencies in Elm.
Sporto's gitbook on Elm is a nice alternative walkthrough from first principles,
if you're interested. Really good content.
The official implementation of TodoMVC in Elm, from Evan (NOTE: We did not
review this when implementing our own, as I thought it would be more interesting
to just do it from scratch based on the specification - I ended up looking at it
to learn how best to handle the
onEnter attribute in 0.18 though, in the
rewrite I'm going through presently).
Elm FAQ, from elm-community
This is a community-driven FAQ for Elm. I learned a few things from it even
after I'd used Elm for quite a while, and it's just going to continue to get
better I'd assume.
Discovering the Elm Language
A great blog post from Nik Silver on his initial experiences with Elm. This
code is not 0.18, but the experiences are all still very real.
More by Nik Silver, explaining fundamental features of Elm via code examples.
Once again, not updated for 0.18 but I haven't yet found an example that would
be different either. Just something to be aware of.
This week we implemented the basics of TodoMVC using Elm. At present, there is
Todo that is added to the model each time you press the enter key
inside of the input field.
For this week's exercise, try to extend our TodoMVC implementation to do the following:
- On every keypress, set the model's text to the value of the input field.
- When the Enter key is pressed, do the following:
- Add the model's todo to the list of todos, rather than the
- Clear the model's todo's title.
