SPFetcherBase

A container for all requests in a Sharepoint webpart

Usage

- Start by extending this class and create your own constructor if necessary.
- Put startup-routines in the method "startupRoutines". This will be called automatically during initialization.
- Start your own methods with return this.ready().then(() => { ... }). This ensures execution once ready.
- While loading your webpart, call Fetcher.initialize to set it up

Example

``ts
class MyFetcherClass extends SPFetcherBase {
// Properties
protected urls: {
absolute: string;
logic: string;
};

// Constructor
constructor() {
super();
this.urls = {
absolute: undefined,
logic: undefined
};
}

// Startup routines
protected startupRoutines(): Promise {
return Promise.all([
this.web
.getStorageEntity('SettingsSite')
.then((r: any) =>
new Web(r.Value).lists
.getByTitle('Settings')
.items.filter("Title eq 'CopyFileLogicAppUrl'")
.get()
)
.then(r => (this.urls.logic = r.value))
]);
}

// Example method: get
public getFiles() {
return this.getDefaultLibrary().then(library =>
library.items.filter(startswith(ContentTypeId,'0x0101')).get()
);
}
}

export const MyFetcher = new MyFetcherClass();
