Determine the current block height directly from the lnd log output and
pass the data into the app as soon as we have it. Do not call out to
block explorers if we don't need to.
`main.dev.js` was hard to follow and understand the code flow. It housed
code to handle quite a few distinct things. This is a fairly substantial
refactor of the application startup code in which we:
A new `Neutrino` class has been created with 2 public methods. `start`
and `stop`. `start` will launch a new `lnd` process whilst `stop` will
stop it. This class extends the `EventEmitter` class and emits the
following events based on activity detected from the lnd log output.
- `grpc-proxy-started` - gRPC started
- `wallet-opened` Wallet opened
- `fully-synced` - lnd is all caught up to the blockchain
- `got-block-height` - got updated block height
A new `ZapController` class has been created which houses all of the
logic for intraprocess communication between the main and renderer
processes.
Previously we had several `setInterval` loops that were checking every
second to see if the application status has changed and trigging the
appropriate action if so. This was pretty hard to follow has been
replaced here with more extensive use of promises. This enables us to
act instantly to relevant changes rather than waiting up to 1 second
for the next interval to fire.
Now, the only stuff that lives in `main.dev.js` now is the top level
`app` listeners, which calls out the other parts mentioned above to
bootstrap the application.
Move rpc.proto into the resources directory along with all of the other
external resources.
Fix up the resource paths to reference external resources correctly
depending on wether the app is being run locally or from a release.
Only one of these files was being used, and they were going out of step
relative to one another.
Put rpc.proto in the resources directory for consistency with other
vendored resources, i.e. the lnd binary
Updated the def from:
https://github.com/lightningnetwork/lnd/blob/master/lnrpc/rpc.proto
Use grpc.credentials.combineChannelCredentials to combine the ssl
credentials with the macaroons when initializing the lnd rcp client.
This avoids the need to pass the macaroon metadata throughout the
codebase.
