This commit removes the need for `EmbarkJS.onReady()` and `EmbarkJS.Blockchain.blockchainConnector` APIs
in the ENS provider implementation and instead relies purely on vanilla `Web3`. This comes
with the effect that `EmbarkJS.Names` needs to figure out itself what to connect
to, as well as when a connection has been established.
To make that possible, `EmbarkJS.Names` now implements a similar algorithm to
`EmbarkJS.Blockchain` that tries to connect different endpoint, given a `dappConnection`
configuration.
If no `dappConnection` configuration is given via `namesystem.json`, Embark will fallback
to the same connection list that's provided in `contracts.js|json`.
wip
When making use of the `useBuiltIns: 'usage'` option for @babel/preset-env
(which is the case for all transpiled packages in Embark's monorepo) a package
needs to have both @babel/runtime-corejs3 and core-js@3 specified as
dependencies.
BREAKING CHANGE:
node: >=10.17.0 <12.0.0
npm: >=6.11.3
yarn: >=1.19.1
node v10.17.0 is the latest in the 10.x series and is still in the Active LTS
lifecycle. Embark is still not compatible with node's 12.x and 13.x
series (because of some dependencies), otherwise it would probably make sense
to bump our minimum supported node version all the way to the most recent 12.x
release.
npm v6.11.3 is the version that's bundled with node v10.17.0.
yarn v1.19.1 is the most recent version as of the time node v10.17.0 was
released.
