We will build a straightforward program to pin their accomplishment on a board

  • have a basic Angular 2 program making use of TypeScript
  • utilizes JSPM/SystemJS to stream dependencies about pages
  • means TypeScript classification documents of libraries using TSD and describes the missing definitions of Angular 2 in a regional document called angular2.temp.d.ts
  • recalls an Express SLEEP API to eat in Angular
  • uses Gulp to transpile TypeScript signal to ES5 and begin a Node.js server
  • has provider TypeScript data that are positioned inside the scripts folder while the community folder is employed to save transpiled data.

Building Express APIs

Now you've a sense of exactly what Angular 2 are along with additionally cloned the seed venture, why don't we alter it. Since the first thing, why don't we put the present APIs receive and incorporate the accomplishments. As I forked the repository and altered the seed project to add fundamental present APIs, you'll see an endpoint serving the present list of every achievements. To publish a fresh achievement, we should instead put an endpoint.

As Angular 2's Http API is still pretty raw, it content the data by means of basic text. Therefore, let's include a bodyParser middleware to see the written text from the consult body:

Modifying Startup Component and Channels

The index.html document is the place to begin regarding the software. The body part of this document tons the bootstrap program and helps to create the my-app element. This element therefore plenty different parts into the application. The bootstrap.ts document bootstraps the AngularJS program making use of the primary part. Just like you read, the mandatory injectables shipped by the additional modules tend to be passed away inside function. This makes the services in addition to directives exported by these segments available to all youngster components of my-app . We are going to use a type into the program as well as for that we want to incorporate formInjectables exported by module angular2/forms on range of the injectables:

The startup part of the project is within the application folder. The aspect has two annotations applied to it:

  1. Ingredient: they retains the setting attributes regarding the component like selector, names of characteristics, names of occasions and range of the injectables inside element. The worth of the selector could be the just like the sequence to be utilized on HTML el-cased
  2. View: The view annotation loads the information required for the view an element of the element. It includes an HTML template (is generally inline or a template Address) and a listing of the directives your component goals

The my-app aspect has to determine the ways when it comes down to program and provide a placeholder to stream the child views. The Router solution may be used within the MyApp lessons to establish the routes. This amazing snippet defines both tracks you'll need for the applying:

Since the add aspect will not be included but, you'll face some problem if you attempt to perform the application form now. We must establish a brand new folder within the elements folder and label it create . Then, we include two files inside this folder: add.ts and create.html . Eventually, include here snippet toward add.ts file (we'll increase the amount of code afterwards):

The scene with this aspect will have a type acknowledging inputs to get conserved as a achievement. Thus, put listed here HTML to this page:

Into the see, we have to generate backlinks for navigating between the pages. The router-link characteristic aspect allows us to in this way. We need to designate title associated with the element of the attribute and it surely will manage design the hyperlink in line with the road previously designed for element.
