  • When we build forms, we know there’s a good chance that the data we want to collect may change.
  • Dynamic Forms in Angular give us the ability to define the underlying object model before binding the form to the template.
  • This lets our forms programmatically adjust to the underlying model so we don’t have to update each form manually as our data will eventually change.
  • In this course Google Developer Expert-led we will use Angular’s Reactive Forms and learn about the basics for dynamically rendering .
  • If you’re coming from AngularJS (v1.x) you may also be familiar with dynamic forms in the context of , a library for automating dynamic forms.

  • It adds the necessary commands to VS Code to add a DockerFile to your existing angular project as follows: – – Once the DockerFile is added to your Angular application its time to add the necessary commands to assemble a docker image which will be used to create docker containers…
  • The beauty of the docker image here is that we don’t have to burden ourselves with setting up an nginx server on either the development or production machines.
  • If you want to test the above setup locally on your dev machine before you integrate it into your CI/CD pipeline you can build the angular application using the following command: – – and then build the docker image using the following command: – – which would result in the…
  • The third and fourth tasks will build the docker image and push it to Azure Container Registry (ACR) respectively.
  • Both your development as well as your production environment are running the same docker container which is utilizing nginx web server to serve your Angular application.

  • To get started, lets install the package thru npm: – – Next, create an action just like you do with NGRX today: – – then you create a class and decorate it with a decorator that contains the initial state for your reducer.
  • Within that class you define methods decorated with the decorator with an argument of the action class you want to match it on.
  • Thats because if it doesn’t see a state returned from the action it inspects whether the state was an object or array and automatically creates a new instance for you.
  • Thats because the decorator can accept single or multiple actions.
  • Next, pass that to your NGRX module just like normal: – – If you want to use NGRX effects, I’ve created a lettable operator that will allow you to pass the action class as the argument like this: – – We didn’t leave out selectors, there is a decorator that…
