Router) a name and use dot notation to define parent-child relations. Note: If you're using ngMin, you'll have to annotate the dependency. Effective Crowd Annotation for Relation Extraction. Angli Liu, Stephen . who failed the controls on more than one third of .. drew Y Ng. sass, uglify, ng-annotate, and 13 other things', and Grunt/Gulp allow you to do the .. is where Grunt or Gulp or any other naive build system will fail immediately. . It's a really powerful way to describe the relationships and.

Too on Dec 9, I found all build systems for all platforms to be a total PITA and eventually i just resort to using a shell or python script to invoke the commands i want. With this method you can very easily add user promting do you want to build debug or release? Whatever i learn here can be applied and reused for new things in the future instead of knowing all the flags of whatever build chain of the day.

This does not mean invoking compile manually on every file but you you invoke the smallest possible build file for your intended platform just for building and absolutely nothing else. Compiling c projects without make would otherwise take hours instead of minutes. Really, Gradle requires you to read the first 12 chapters of the manual before you can even begin doing something more advanced than running compile.

Msbuild likewise, it's like a completely new programming language just that it's written in xml. Bamboo is just like imperative programming except you have to drag and drop boxes that invokes commands or plugins yep, another plugin hell.

CMake works kindof painlessly but it also requires a lot of black magic when you want to add dependencies outside of the c buildchain. The only one that actually doesn't make you cry is 'make' because it's so simple, it's just doing one thing instead of trying to tie itself into the entire ecosystem badly. Make also has it's problems but when you start hitting those it's more of a sign that you are trying to add too much weird logic that should not be in the build script to begin with.

You can easily add prompting with maven, gradle etc, test result reporting, source control integration is all built in. Inject So where does Inject come into play? We could alternatively write our component like this: This could and will get very messy when a component or service requires a lot of dependencies.

The reason we use Inject is because we cannot use an OpaqueToken as the type of a parameter, for instance this will not work: However, when we introduce Inject alongside an OpaqueToken, things will work out nicely: This may change however, as there is a current issue to make Injectable mandatory however this is pretty fresh and may not land for a while, or ever.

When using Angular decorators, the decorated class stores metadata about itself in a format that Angular can read - this includes the metadata about what dependencies it needs to fetch and inject. If no Angular decorator has been used on a class there is no way for Angular to read what dependencies it requires.

This is why we need to use Injectable. If our service injects providers we must add Injectablewhich providers no extra functionality, to tell Angular to store that metadata it needs. Therefore, if our service looks like this: However, if our service looks like this and contains a dependency Http: We can simply add Injectable to solve this: Tokens and Dependency Injection Now that we know how Angular knows what to inject, we can learn how it resolves our dependencies and instantiates them. This means that Angular can look up what is stored under the token for AuthService using the useClass value.

This provides many benefits. Each handler uses the store. In a more complex app, you may wish to dispatch actions in an actions creator service that can be injected into your components. However, for our small app and for learning purposes, this is unnecessary, so we will dispatch actions directly from our smart components using constants from our actions creator, pet-tag.

You can lint your project at any time by running the following command: If any errors are found, correct them before proceeding. It's good practice to lint periodically throughout development to maintain clean code.

The linting configuration can be found at tslint. Tag Shape Component Now we'll build our first presentational component: When we're finished with this component, the Create page should look like this: Let's generate the scaffolding for this child component with the following Angular CLI command: The user can select which shape they'd like for their custom pet tag.

Our tag shape selector will use radio buttons, so we'll need a property to store the shape ngModel. The shape name options are strings, so we'll set tagShape's type annotation to string. Next we need an Output decorator to emit an event when the user selects a shape.

This will send the information to the parent CreateComponent. The selectShape shape method will emit the event with shape information. The parent can then handle this event with the selectShapeHandler method we created earlier in CreateComponent. We'll hook this up to the parent shortly. When any input is selected, we'll use the change event to fire our method emitting the selectShapeEvent with the tagShape as its argument. Tag Shape Component Styles This component could use a little bit of styling beyond Bootstrap, so add the following to the tag-shape.

Create a customized tag for your pet.

Tag Text Component Next we'll create a child component that lets the user choose a font style and enter the text they'd like on their pet tag. Our Create page will look like this once we've added our tag text component: Generate the component scaffolding with the following command: We aren't adding string type annotations to our properties because declaring initial values allows types to be inferred automatically. We'll emit events when the user updates the tag text or changes the font style selection.

Tag Text Component Template Our tag text component template, tag-text. The ngModels are updated on user input and events are emitted to the parent component. Tag Text Component Styles We'll add just one ruleset to tag-text. We only want this component to appear once the user has selected a shape. This is because we're going to create a preview of the tag soon, and it doesn't make sense to show a preview unless a shape has already been selected. This prevents users from entering text or extra tag options before choosing a shape.

Once we've implemented the tag extras component, our Create page will look like this: Create the scaffolding for TagExtrasComponent with this command: Tag Extras Component Template Add the necessary markup to the tag-extras. Tag Extras Component Styles We want to add a bottom border to our host element since this is the last component before we'll show the customized tag preview.

Add the following to the tag-extras. Recall that we set up the reducer to use the previous state to determine the next state in these cases.

Tag Preview Component Now let's create a component that shows a simple preview of the pet tag as it's being created. After we've implemented the tag preview presentational component, we'll be able to view the tag like so: Let's scaffold the TagPreviewComponent. This component will be a child of both the Create and Complete pages, so let's create it in the root of the app folder like so: Import the Input decorator and the OnChanges lifecycle hook. We also need the PetTag model so we know what shape to expect from the input.

We'll need this in order to update our preview whenever the user modifies their custom pet tag. The Input petTag that we'll be receiving from the parent component is the state object, which has the shape declared by the PetTag model we defined at the beginning. For example, it might look something like this: We'll do this by showing an image of the tag with user-inputted text and notes about whether the user has chosen to include a clip or gems.

We'll set the image source as well as the tag clip and gems option text "Yes" or "No" when changes to the input are detected. Tag Preview Component Template Open the tag-preview. We'll display the appropriate shape SVG image and a shape class.

We'll also display the pet tag text in the appropriate font using a class with the font value. Finally, we'll print out whether the user has chosen to include a tag clip or gems.

Tag Preview Component Styles Recall that there are four possible tag shapes: In order to display a nice preview with any of these shapes, we'll need some additional styling.

We already established our local petTag property in the CreateComponent's tagStateSubscription, and we're passing this to the tag preview component.

Now we should be able to see live changes in the tag preview as we customize our tag: Submit Completed Tag Now that we have our tag builder and preview built, let's add a "Done" button to submit the finished tag to the Complete page. When implemented, our Create page should look like the following: All we need to do is create a button that calls this method in our create.

We declared done in the CreateComponent's tagStateSubscription earlier. It looks like this: If the user has added these, then they will be able to click the button to submit their tag.

We'll also route the user to the Complete page. Once we've implemented the component, the Complete page will look something like this after the user has created a custom pet tag: PetTag; constructor private store:
