A podcast about using Elm coming from Javascript and other languages

Episodes

  • Elixir Fundumentals

    09/08/2019 Duration: 17min

    Covering the basics Elixir has truthy and falsy Boolean conditionals. I feel right at home Variable assignment can only happen on the left side of the equal For a match to succeed, the LHS and RHS must have the same shape, and each value on the right must match the corresponding value on the left. If the thing on the left is an unbound variable, Elixir binds that variable to the value being matched. The LHS cannot contain any calculations or function calls Using _ for ignoring values. Helpful in getting a RHS and LHS match All variables on the LHS of a match are unbound before the match is made. Solution is to use the pin up arrow, *^ to prefix the variable Only your posts users should only see their posts. all posts will show on the home page Resources Dave Thomas the Coding Gnome calling an external idp api get all entries by user id Travis CI and a VPS Realworld App Follow JavaScript to Elm Twitter: @jstoelm Email: jesse@jstoelm.com Jesse Tomchak Twitter: @jtomchak  

  • Elixir Ecto Models

    Deploy Missing Piece Need for distillery to run migrations on deploy We need to create release tasks that will go in the root of lib. That will have a migration and / or seed function in it. Then in the rel/config.exs we a list of tuples that have the task command, what we want to refer to it as, and the the shell script that we want it to run. Remember mix isn’t installed on the prod machine! the shell script just calls bin/postit command Elixir.Postit.ReleaseTasks migrate Then we, to run migration on app launch for new builds, back in rel/config.ex we add set post_start_hooks: "rel/hooks/post_start" to env prod. in this directory we have a single shell script that will use nodetool to ping when the, not app, but BEAM? is up and running, and then run the migration. #!/usr/bin/env bash set +e while true; do nodetool ping EXIT_CODE=$? if [[ ${EXIT_CODE} -eq 0 ]]; then echo "Application is up!" break fi done set -e echo "Running migrations" bin/postit command Elixir.Release.Tasks

  • Elixir with Auth0

    18/07/2019 Duration: 32min

    Auth I have no desire to roll my own. While a lot can be learned from this type of exercise, it is not something I want to get hung up on. Plus it’s a MONSTER subject. Not one to be taken lightly, so we’ll outsource the safe keeping of user info and the authentication mechanics. So we can focus on the implementation of it. auth0 authenticated app Adding some event counter for sampling mix phx.gen.html Events Event events title due:datetime I’ve never been a fan of generators like this before, but I am also tired of hand carving the same things over and over in my React apps. So I’m all in. Add the resource to your browser scope in lib/postit_web/router.ex: resources "/events", EventController Remember to update your repository by running migrations: $ mix ecto.migrate plus the cli is super nice and very informative Add a route events to the router under lib/postit_web/router.ex within the scope of PostitWeb Run migration. This I like. I know enough sql to find my way in the dark, but I much

  • Elixir with AppEngine

    11/07/2019 Duration: 23min

    AppEngine Remember what started us down the path of managing a kubernetes cluster in the first place? No, it wasn’t our own sadistic desire to to devops in an effort to avoid building an actual project, but close. We want to be able to leverage ‘live view’ in our project, that requires websockets, which all signs pointed to not available on appengine. But wait, what’s this? App-Enggine WebSocket Support As of Feb 2019, it looks like we’re good to go. That coupled with the $30/month bill we would incur when our gcp credits ran out, this switch seems to make a lot of sense. Clean up Tearing down services kubectl delete service postit-web gcloud compute forwarding-rules list use this to check that the loadbalancer is also removed and finally the cluster of 2 VM’s gcloud container clusters delete --zone=us-central1-a postit-cluster then just the database. and we’re all set to startup with app-engine App Engine update KMS key/value on key for beta app. remember we tore everything down and needed to create

    Elm In the Spring Videos are up LINK Announcing Elm UI-Explorer I was gonna steer clear of this topic after initially reading the post by Chris Gregori Elm and why its not quite ready yet , and the follow up by Lucas Payr How Can the Elm Coummity Imporve , but it sort of festered on my mind, which listening to this reason behind this weeks tardy release. I have another episode in the cooker, one that was a lot more fun to work on, but there was something about this open conversation that I just can’t shake. There is no answer here, only those searching That’s my disclaimer. Summary I think both articles from Chris and Lucas where thoughtful, articulate and constructive. I didn’t get any sense of trolling, flaming, or even so much as a hint of rudeness. Chris wrote on article titled ‘Elm and Why it’s Not Quite Ready Yet’ where he outlines several points that he believes makes Elm, as the title suggests, not ready for prime time. To be fair, he does list a fair amount of good points and things that he lik

  • Yearly Themes Check-in

    23/05/2019 Duration: 24min

    We set out this with a theme this year. Not a resolution, but an idea of something tangible that wanted to accomplish or do better in our efforts here. If you're not super familiar with themes, as I was not, I'd encourage you to listen to Cortex on Relay FM, of course they are in the show notes.   Cortex #79: 2019 Yearly Themes - Relay FM   Cortex #62: 2018 Yearly Themes - Relay FM   Actual Reddit thread gives a good rundown of yearly themes, but for me it's really something you can ask yourself when you're doing something, or you're looking at your to do list, or list of projects you want to work on. Whether those are side projects, or maybe they are part of your business in the case of Myke and Grey. (Those are the peeps from the show Cortex)   So what was my theme? Creating Content and Simple Automation. Episode #64 Aptly titled 'Themes' goes into both in pretty good detail, and I thought since it's nearly the 1/2 way point of the year, how am I doing?   The idea, whenever I start in on someth

    CFP for Elm-Conf You have sometime to get a proposal in. I’d love to hear what you have to say about your latest Elm or functional related adventures. I’ve submitted one of a couple of my ideas, I encourage you to do the same. Lost in Routing if you listened last week, and were a bit confused, you are not alone. I too am trying to unlearn a lot of habits good and bad that I baked into my mental model of an SPA. Prop passing is muscle memory at this point, and I’m having a hard time not picturing the model of my application that way. First things first - THROW OUT THE COMPONENTS NAMED FILE Better? cool. Let’s start again. Views are functions, they are composable together. I am not entirely sure what _main was referencing in the components file. And it’s even harder to google something for which you don’t have a name to describe it with. Back to basics Understanding what FRP is? Goals for today, what is FRP First order FRP Elm Intro Jeremy Fairbanks Model -> View -> Update View is a reflection o

    Elm in the Spring A huge shoutout and thank you to the organizers: Blake Thomas @dijjnn Alex Koppel @arsduo Caroline Artz @carolineartz also xt thank you for the awesome socks! Colleen Sain @colleeninsain Doug VonMoser @dougvonmoser Special shoutout to friend of the show Anthony Deschamps programing Robots with Elm. It was great to catch up in Chicago, if only for a moment. All of the talks were top notch, original content, beautifully delivered. I was mentally fried by the end of the day. The library was a great space. I remembered what a coat rack was, and special thanks for the incoming blizzard the next morning as my plane received not 1, but 2 de-icing to get out and on it’s way to the sunny desert. Favorite moments - Andrew MacMurrary @a_macmuray went through his experience of building a game, Seeds the game let’s be real, games demo so well, and Andrew’s game is absolutely gorgeous Dan Abrams @thedanabrams. on his crazy screenplay parser and some of the hoops he’s gone through to get that workin

  • Route Components

    24/04/2019 Duration: 26min

    From Page to Component Keeping our application modular, that means components Not your React Components Basically an Elm app that doesn’t expose a program Does not have a ‘main’ Rather it exposes it’s model/init, update, and view functions for other Elm modules to use Sound similar to life cycle methods? The modules state will be stored in the main with a little ‘m’ model expose Model, Msg, update, view and init doesn’t take () unit any more. Remember it’s called unit!!! Why doesn’t it? bc it’s not being invoked with the arguments that main would be, it’s exposing the other functions that it has. maybe? Gettin’ it done Storing an instance of the component’s model in Main’s model? Maybe not so much. The effect would be growing fields in the model for each and every component.

    Routing in Elm I realize now, just how frustrated people get when learning n framework or language. For me that monster is routing in Elm. But first, you’re running out of chances to get to Elm in the Spring!!! Instead of creating our program with Browser.element or Browser.document, we can create a Browser.application to avoid loading new HTML when the URL changes: ok, cool. Define some routes, in a Routes.elm file preferably in it’s own Routes file Define the routes Parser -- creating a parser called 'routes' -- will produce routes of type Route -- doesn't take any arguments? routes : Parser (Route -> a) a routes = Parser.oneOf [ Parser.map Home Parser.top , Parser.map Account (Parser.s "account") ] Define a match function that will convert a Url and return a Maybe Route. Maybe Route because you might not have a matching route, right? I think this is where the default case for pattern matching at one point will show the 404. Be sure we are exposing the Routes(..)

    bit of history Macros can be used to make tasks less repetitive by representing a complicated sequence of keystrokes, mouse movements, commands, or other types of input. In computer programming, macros are a tool that allows a developer to re-use code. best explianation i have found so far Fundamentally, macros are a way of writing code that writes other code, which is known as metaprogramming. rust docs macro is going to happen at compile time. where a function is going to happen at run time. code that writes code.
