Page does not load at all if bitcoind still indexing transactions

[firepol]

Describe the bug

bitcoind downloaded the entire blockchain, but is still indexing transactions. btc-rpc-explorer can't be accessed at all. I'd expect at least to see the UI and only if I hit the search with an address that is not indexed yet I should get an error. Or show the UI and disable all buttons and show a message that indexing is still processing. It''ll be more user friendly.

Same problem while downloading the blockchain. I was expecting that if I don't query the blockchain, at least I could see the basic UI of btc-rpc-explorer. The HTML page I mean...

Yes, this is known to happen. If your node hasn't fully synchronised with the entirety of the chain, page/UI does not load and you might have several errors. - RPC connection failed, error response 1 etc. I have the same issue.

Some fix/suggestion would be for the UI to load regardless if the node synced or not and at least show some info such as: "Synchronising please wait" or "The results are not up to date, please wait until the chain is fully synchronised" - but at least to be able to show something to know that the UI works. It took me couple of hours to realise that it wasn't a problem with the code and it was actually still synchronising. #247 @janoside
