Auto refresh on metamask account switch - MyBit Trust

[mybit-bot]

Introduction: To enhance the user experience of MyBit Trust (trust.mybit.io) we want the application to automatically refresh when a user switches between different metamask wallets.

Current behaviour: Requires manual page refresh by user.

Desired behaviour: Automatically refreshes when new wallet in metamask is selected.

Hi @mybit-bot ! I found a solution and opened a pull request MyBitFoundation/MyBit-Trust.app#4

I set up a callback in BlockchainInfo context that listens to 'update' event on Metamask
publicConfigStore. This callback is triggered whenever there is an update to the store. If selectedAddress is different than the current one, automatic refresh happens. I can apply later the same solution to 'Will' app.

I will try to push to the staging area today.

Hmm that's interesting, there is no open claim visible https://openbounty.status.im/app#/ perhaps it is because the pull request is in the different repo than this one?

@csmartinsfct can you review?

[cryptomental]

@cryptnotiq @csmartinsfct and it is deployed here : https://mybit-trust-user-autorefresh.herokuapp.com/

You can verify this by opening Metamask and changing the user while the app is running.

@csmartinsfct @kyledewy can you test that staging URL? None of the buttons are functioning for me, but could be a bad internet connection.

[cryptnotiq]

hey @cryptomental the staging link isn't working for any of us. It loads eventually but then none of the buttons are functional. Can you look into it?

[cryptomental]

Hi @cryptnotiq @csmartinsfct @kyledewy indeed! It hangs now on api.bancor.network perhaps it hit Bancor calls limit ?

An hour ago the staging app worked blazing fast but I was trying it out for 15-20 minutes so it might have triggered too many calls. I will wait a few minutes and try again.

I am thinking whether to switch to another staging area provider, perhaps free Heroku tier is not enough... What are you using for staging area?

[csmartinsfct]

We use now.sh

[csmartinsfct]

But a bancor widget problem shouldn't make the website unusable, should it? @cryptomental

Feel free to host a version with the bancor widget disabled because if that is the issue then we'll have to fix it but it isn't related to this PR.

[cryptomental]

Ok thank you @csmartinsfct I will try out now.sh.

I nailed down that it hangs here:

which is https://api.bancor.network/0.1/currencies/rate?toCurrencyCode=ETH&fromCurrencyCodes=USD,EUR

This works perfectly locally for me (website deployed locally as well).

[csmartinsfct]

I wonder why it's hanging, we're using the widget in our Go dApp and never had that issue. Although the implementation is different in both projects.

Yea feel free to post a staging URL with the widget disabled.
