Tutorial: Tour of Heroes
|
||
|
||
@intro
|
||
The Tour of Heroes tutorial takes you through the steps of creating an Angular application in TypeScript.
|
||
|
||
@description
|
||
Our grand plan for this tutorial is to build an app to help a staffing agency manage its stable of heroes.
|
||
Even heroes need to find work.
|
||
|
||
Of course we'll only make a little progress in this tutorial. What we do build will
|
||
have many of the features we expect to find in a full-blown, data-driven application: acquiring and displaying
|
||
a list of heroes, editing a selected hero's detail, and navigating among different
|
||
views of heroic data.
|
||
|
||
The Tour of Heroes covers the core fundamentals of Angular.
|
||
We’ll use built-in directives to show/hide elements and display lists of hero data.
|
||
We’ll create a component to display hero details and another to show an array of heroes.
|
||
We'll use one-way data binding for read-only data. We'll add editable fields to update a model
|
||
with two-way data binding. We'll bind component methods to user events like key strokes and clicks.
|
||
We’ll learn to select a hero from a master list and edit that hero in the details view. We'll
|
||
format data with pipes. We'll create a shared service to assemble our heroes. And we'll use routing to navigate among different views and their components.
|
||
|
||
We’ll learn enough core Angular to get started and gain confidence that
|
||
Angular can do whatever we need it to do.
|
||
We'll be covering a lot of ground at an introductory level but we’ll find plenty of links
|
||
to chapters with greater depth.
|
||
|
||

||
## The End Game
|
||
|
||
Here's a visual idea of where we're going in this tour, beginning with the "Dashboard"
|
||
view and our most heroic heroes:
|
||
|
||
<figure class='image-display'>
|
||
<img src='/resources/images/devguide/toh/heroes-dashboard-1.png' alt="Output of heroes dashboard"> </img>
|
||
</figure>
|
||
|
||
Above the dashboard are two links ("Dashboard" and "Heroes").
|
||
We could click them to navigate between this Dashboard and a Heroes view.
|
||
|
||
Instead we click the dashboard hero named "Magneta" and the router takes us to a "Hero Details" view
|
||
of that hero where we can change the hero's name.
|
||
|
||
<figure class='image-display'>
|
||
<img src='/resources/images/devguide/toh/hero-details-1.png' alt="Details of hero in app"> </img>
|
||
</figure>
|
||
|
||
Clicking the "Back" button would return us to the "Dashboard".
|
||
Links at the top can take us to either of the main views.
|
||
We'll click "Heroes". The app takes to the "Heroes" master list view.
|
||
|
||
<figure class='image-display'>
|
||
<img src='/resources/images/devguide/toh/heroes-list-2.png' alt="Output of heroes list app"> </img>
|
||
</figure>
|
||
|
||
We click a different hero and the readonly mini-detail beneath the list reflects our new choice.
|
||
|
||
We click the "View Details" button to drill into the
|
||
editable details of our selected hero.
|
||
|
||
The following diagram captures all of our navigation options.
|
||
|
||
<figure class='image-display'>
|
||
<img src='/resources/images/devguide/toh/nav-diagram.png' alt="View navigations"> </img>
|
||
</figure>
|
||
|
||
Here's our app in action
|
||
|
||
<figure class='image-display'>
|
||
<img src='/resources/images/devguide/toh/toh-anim.gif' alt="Tour of Heroes in Action"> </img>
|
||
</figure>
|
||
|
||
|
||
## Up Next
|
||
|
||
We’ll build this Tour of Heroes together, step by step.
|
||
We'll motivate each step with a requirement that we've
|
||
met in countless applications. Everything has a reason.
|
||
|
||
And we’ll meet many of the core fundamentals of Angular along the way. |
