@dittops https://github.com/tradingview/charting-library-examples/tree/master/angular5 ? What do you need ? An Angular5 example without TypeScript ?

@alex need a sample of JS api for live streaming of data with sockets in typescript way. I couldn’t find a sample for that.

If you interested in example, it's super easy (but no information in wiki found):

import { Injectable } from '@angular/core';

import * as TradingView from 'assets/lib/tradingview/charting_library/datafeed-api.d';

import { TradingViewService } from './trading-view.service'; // your http data service

@Injectable()
export class TradingViewDataProvider implements TradingView.IDatafeedChartApi {

constructor(private tradingViewService: TradingViewService) { }
   
    // implement TradingView.IDatafeedChartApi interface here
 
    // for example:

public getBars(
        symbolInfo: TradingView.LibrarySymbolInfo,
        resolution: TradingView.ResolutionString,
        rangeStartDate: number,
        rangeEndDate: number,
        onResult: TradingView.HistoryCallback,
        onError: TradingView.ErrorCallback,
        isFirstCall: boolean
    ) {

        this.tradingViewService.getBars(
            symbolInfo,
            resolution,
            rangeStartDate,
            rangeEndDate,
            isFirstCall).subscribe(
                data => onResult(data, { 'noData': false }),
                error => onError(error));
    }

}

@pumano how do you connect this to JSAPI as it's expecting an object with these functions. If we are using the classes, how do you pass just the object back without the DI?

@moderniinfotech-123 the code is shared is using UDF format If I'm correct. I'm looking for the JSAPI for realtime injection using sockets.
