Notes du workshop Découverte de Elm

Le workshop elm était très sympa, le présentateur, Jordane, est très bon et son tuto par étapes est très bien fait, détaillé et interactif (faisable en solitaire aussi).

Elm

• no runtime exception: if it compiles, then it works!
  • il n'est pas possible d'avoir des exceptions
    • division by 0 -> Infinity
    • fonctions obligatoirement pures
• if toujours avec un else

Choice of full stack SPA framework: some of my criterion

Orthogonality of css/html/js/build

• each should be upgradable without impacting the other
  • otherwise plan for quite some yak shaving once you need to update one of these bits
• style and code are 2 distinct things

Web proximity

• other css/js should be easily usable
• push/notification/dynamic content should all be possible

String initialFieldName = "text";

        .record("OneFieldSchema").namespace("avro.trial")
        .fields()
        .name(initialFieldName).type().stringType().noDefault()
        .endRecord();


Schema oneFieldSchemaWithRenamedFieldAndAlias = SchemaBuilder.builder()
        .record("AliasedOneFieldSchema").namespace(oneFieldSchema.getNamespace()).aliases("avro.trial.OneFieldSchema")

        // is correctly handled
