TypeError: window.TradingView is undefined

Hello whenever I try to reuse the component TVChartContainer /> i get the following error TypeError: window.TradingView is undefined

The charting library isnt included, you need to download it separately from tradingview

Hello again the thing is that I have the libraries included from the private repository. Just I have my webapp in react and I try to include your implementation files to my project.

same error

[BStephenBB]

Yes, I'm getting the same error as well, and I have included the charting library properly. I figured out the problem: in the repo nothing is ever imported from the charting library, so of course TradingView is undefined; it's never imported! I fixed and got it to work by importing { widget } from the trading view library, and then using

tvWidget = null;
const tvWidget = new widget(widgetOptions);
this.tvWidget = tvWidget;

in my code instead of this repo's window.TradingView.onready implementation. @AndriusDK @nicqchen @jianqiangsong let me know if this works for you guys and if you're still stuck I'd be happy to make a PR to the repo so you can see what to do. Good luck!

It works thanks!

@BStephenBB can you please provide complete code as i am unable to make this working

[Albot15]

Does anybody have a solution on this? I am also getting the same error "TypeError: window.TradingView is undefined".

I have included charting library.

[BStephenBB]

@vnsfin @drajvat See my comment above on how to get this working, I put the important lines of code there. I'm very busy right now, but can provide a full file-example later when I get the time if it's still not working for you guys.

[SatAndrei]

Can anyone post the line of importing the Widget?

Hei. I've tried to insert your solution in my index.jsx but i get that error. Can you please provide the whole file?

My index.jsx file looks like this:

[rokoz77]

You already have a widgetOptions so you don't have to add it
You only need to import tv.js lib
Maybe you need to download it

Edit : sorry i'm talking about somethink else

@BStephenBB
Hello.
I've tried your solution and posted my index.jsx and errors above. I can't figure out where to export the {widget} from.

using this into /src/components/TVChartContainer/index.jsx
import { widget } from '../../charting_library/charting_library.min.d.ts';
I have
TypeError: __WEBPACK_IMPORTED_MODULE_3__charting_library_charting_library_min_d_ts__.widget is not a constructor

What is wrong with my import?

[miky9585]

I've solved. Maybe is useful for someone else.
Step 1) You need to copy charting_library into /src folder too (not only in public!)
Step 2) Put /* eslint-disable */ at the top of /src/chrating_library/charting_library.min.js
Step 3) Include widget with this code into /src/components/TVChartContainer/index.jsx
import { widget } from '../../charting_library/charting_library.min';
without extension
Step 4) put tvWidget = null; before componentDidMount()
Step 5) Remove everything start with "window.TradingView" and paste with this

const tvWidget = new widget(widgetOptions); this.tvWidget = tvWidget; this.tvWidget.onChartReady(() => { console.log('Chart has loaded!') });
