Angular2 http synchronous

Question

Please help me make an example about http with synchronous in Angular2?

I tried as below: In component:

getAllAddress(){ this.addressService.getAllAddress().then( result => { this.data = result.list; this.onChangeTable(this.config, null); console.log('FIRST'); } ); console.log('LAST'); } 

In the service:

 public getAllAddress(){ return this.__http.get('LOCATION') .map((res) => { return res.json() }) .toPromise(); } 

But the console show log is "LAST" to "FIRST".

Thanks.

You will need to create your own Connection and ConnectionBackend classes that will be implemented when the application loads. See code example below.

 export class XHRSynchronousConnection implements Connection { } export class XHRSynchronousConnectionBackend implements ConnectionBackend { } 

You can download it as follows

 bootstrap([provide(ConnectionBackend, {useClass:XHRSynchronousBackend}), provide(Connection,{useClass:XHRSynchronousConnection}]; 

You can see the rest of the code in the actual source code .
