Angular: Building professional Single Page Applications

Cursusbeschrijving

Je leert de ins en outs van een Angular-applicatie kennen, inclusief TypeScript, Angular Modules, Components, Pipes, Services en Directives.

Het bouwen van een echte Angular-applicatie brengt ook heel wat uitdagingen met zich mee. Daarom leer je in deze training meer aspecten kennen. Je:
Ontwikkelt een echte applicatie van de grond af aan.
Leert strategieën kennen om type-safety te verhogen met behulp van TypeScript.
Ontwikkelt unit-, integratie- en End To End (e2e) tests.
Leert technieken om de state in je Angular-applicatie te managen.
Leert de huidige best practices op het gebied van Angular.

Deze training is opgesplitst in basis en advanced. Tijdens de eerste 2 dagen leer je de basis kennen, met onder andere de basis van TypeScript, Pipes, basis van testen, formulieren en componenten. Tijdens de 2 volgende dagen leer je geavanceerdere concepten zoals Angular modules, advanced TypeScript, reactive programming, end-to-end testing en change detection. Zowel ‘core’ en ‘advanced’ zijn ook los af te nemen als incompany training.
