};

const loadingOptions = {
  timeout: 8000,
  spinner: spinner
}

const loading =  new LoadingPro(loadingOptions?); // option is optional here
loading.spinner = spinner;

Start a loading call

call this method to start a loading call, if user didn't inject id will return a random id.

Tips: recommend give an Id for loading, so you can clear see which loading not finished.

const loadingId = loading.start("getUserLoading"); // loadingId = 'getUserLoading'
const loadingId = loading.start(); // loadingId = {A random shot id}

End a loading call

call this method to stop a loading, need provide id

loading.stop(id); // Id for stop which loading

Individual loading will not plus in the normal loading, it has self life time.

Start Individual Loading

loading.startIndividualLoading(id?); // loadingId = given id or {A random shot id}

Stop Individual Loading

loading.stopIndividualLoading(id);

Get loading status

here i offered two way to get loading status, one is a attribute called "isLoading"

loading.isLoading; // true

if you want to get the id list which is in loading status

loading.activeItems; // ['loading1', 'loading2']

another way to get loading status is callback function. you can set the callback function to loadingStateChangeHandler this handler will be called every time the status change

  interface ILoadingStateChange {
    newState: boolean;
  }

  loading.loadingStateChangeHandler = ({newState}: ILoadingStateChange) => {
    console.log(newState); // true
  }

for the case loading running to timeout, we will shutdown the loading. and there is a callback function can get the unfinished items.

  loading.shutdownHandler = (unfinishedIds: string[]) => {
    console.log(unfinishedIds); // ['1', '2', '3']
  }

Other Method

• update timeout

loading.timeout = 80000;

• check someone's loading status

loading.check(id); // check the given id is in loading status

Spinner

• update percentage value

spinner.percentage = value;
