During `embark test`, the contracts dapp was throwing an error:
```

This was due to the fact that during testing, the Ganache VM **provider** is used as the blockchain node, instead of spinning up an instance of Ganache. Due to this, there is no HTTP nor WebSockets RPC endpoint opened on the VM node, and the contracts dapp was not able to connect to the node during tests.
Add `$EMBARK` to the contract config’s `dappConnection` list, so that the contract test dapp can successfully connect to Embark’s proxy, which ultimately communicates with the Ganache VM.
As a side note, without `$EMBARK` in the `dappConnection` list, the tests could run successfully when using `embark test —node=embark`. This succeeds because the geth node exposes the RPC WebSockets endpoint that the contracts app connects to on `ws://localhost:8546`.
This PR replaces #2057.
Implement a collective typecheck action that can be invoked in the root of the
monorepo with `yarn typecheck` or in watch-mode with `yarn watch:typecheck`.
Include the watch-mode typecheck action as part of `yarn start` (a.k.a
`yarn watch`).
To activate collective typecheck for a package in the monorepo, its
`package.json` file should specify:
```
{
"embark-collective": {
"typecheck": true
}
}
```
*-or-*
```
{
"embark-collective": {
"typecheck": {...}
}
}
```
Where `{...}` above is a `tsconfig.json` fragment that will be merged into the
config generated for the package according the same rules that `tsc` applies
when merging [configs][config].
When collective typecheck begins, it generates a `tsconfig.json` for the root
of the monorepo and for each package that is activated for the action. If the
generated JSON is different than what's on disk for the respective root/package
config, or if the config is not present on disk, then it will be
written. Changes to generated `tsconfig.json` files should be committed; such
changes will arise when there are structural changes to the monorepo, e.g. a
package is added, removed, moved and/or the directory containing it is
renamed. Since the configs are only generated at the beginning of collective
typecheck, when structural changes are made in the monorepo `yarn typecheck`
(or `yarn start` or `yarn watch:typecheck`) should be restarted.
Nearly all of the packages in the monorepo (i.e. all those for which it makes
sense) have been activated for collective typecheck. Even those packages that
don't contain `.ts` sources are activated because `tsc` can make better sense
of the code base as a whole owing to the project references included in the
generated `tsconfig.json` files. Also, owing to the fully cross-referenced
`tsconfig.json` files, it's possible for `tsc` to type check the whole code
base without babel (`yarn build` or `yarn watch:build`) having been run
beforehand.
**NOTE** that a *"cold typecheck"* of the whole monorepo is resource intensive:
on this author's 2019 MacBook Pro it takes around three minutes, the fans spin
up, and `tsc` uses nearly 0.5 GB of RAM. However, once a full typecheck has
completed, the next full typecheck will complete in a few seconds or less; and
when running in watch-mode there is likewise a *big* speedup once a full
typecheck has completed, whether that full check happened before it's running
in watch-mode or when watch-mode itself resulted in a full check before
switching automatically to incremental check, as well a corresponding *big*
reduction in resource consumption. A full check will be needed any time
`yarn typecheck` (or `yarn start` or `yarn watch:typecheck`) is run in a fresh
clone plus `yarn install`, or after doing `yarn reboot[:full]` or `yarn reset`.
The combination of options in each generated package-level `tsconfig.json` and
the root `tsconfig.base.json` result in `tsc` writing `.d.ts` files (TypeScript
declaration files) into the `dist/` directory of each package. That
output is intended to live side-by-side with babel's output, and therefore the
`"rootDir"` option in each generated config is set to `"./src"`.
In projects activated for collective typecheck, `.js` may be converted to `.ts`
and/or `.ts` sources may be added without any additional changes needed in
package-level `package.json`.

Reorganize types in `packages/core/typings` (a.k.a `@types/embark`) into
`packages/core/core` (`embark-core`), refactor other packages' imports
accordingly, and delete `packages/core/typings` from the monorepo. This results
in some similarly named but incompatible types exported from `embark-core`
(e.g. `Events` and `EmbarkEvents`, the latter being the one from
`packages/core/typings`); future refactoring should consolidate those types. To
avoid circular dependency relationships it's also necessary to split out
`Engine` from `embark-core` into its own package (`embark-engine`) and to
introduce a bit of duplication, e.g. the `Maybe` type that's now defined in
both `embark-i18n` and `embark-core`.
In the process of the types reorg, move many dependencies spec'd in various
`package.json` to the `package.json` of the package/s that actually depend on
them, e.g. many are moved from `packages/embark/package.json` to
`packages/core/engine/package.json`. Related to those moves, fix some Node.js
`require`-logic related to bug-prone dependency resolution.
Fix all type errors that appeared as a result of activating collective
typecheck across the whole monorepo.
Reactivate `tslint` in `packages/core/core` and fix the remaining linter errors.
Tidy up and add a few items in the root `package.json` scripts.
Bump lerna from `3.16.4` to `3.19.0`.
Bumpt typescript from `3.6.3` to `3.7.2`.
Bumpt tslint from `5.16.0` to `5.20.1`.
Make various changes related to packages' `import`/`require`ing packages that
weren't spec'd in their respective `package.json`. More refactoring is needed
in this regard, but changes were made as the problems were observed in the
process of authoring this PR.

Users can turn of blockchain support if they want to using the blockchain.js
configuration. In practice however, this has never properly worked as several
places in Embark's codebase weren't actually honoring that configuration value.
This commit introduces the necessary changes so that disabling blockchain support will:
No longer generate blockchain related EmbarkJS artifacts
No longer try to deploy Smart Contracts but still compile them
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`.

BREAKING CHANGE:
Related to #1985. Prior to Embark's minimum supported version of Node.js being
bumped to to 10.17.0, Embark was incompatible with any relatively recent
release of the `ipfs-http-client` package.
While *internal* changes are needed re: ipfs's `Buffer` export for
e.g. `embark_demo` to function correctly *(and this PR makes those changes)*,
Embark otherwise runs/tests okay.
Keep in mind #2033.
However, if a dApp author were to explicitly `require('ifps-api')` in the
front-end that wouldn't work as before; and swapping `"ipfs-http-client"` for
`"ipfs-api"` might also not be enough — there are API changes that dApp authors
would need to consider, regardless of Embark presently supplying the dependency
and EmbarkJS wrapping around it.
Closes#1994.
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.

Upgrade all dependencies on web3/web3-* v1.0.0-beta.37 to v1.2.1.
Make various adjustments related to the previous convention of
`"web3": "1.0.0-beta"` in `embark.json` signifying that embark's own web3
dependency should be used in dapp builds.
Fix bugs in library manager, including a switch from using the
live-plugin-manager package to using npm in a child process to install
`"versions"` dependencies specified in `embark.json` when a specified version
doesn't match up with embark's own version for that package.
Avoid race conditions when installing `"versions"` by completing all installs
prior to starting other services. If an install fails, then after all the
installs have completed or failed the embark command will exit with error.
Change various comments and update docs to reflect the new default of web3
v1.2.1.
`EmbarkJS.Messages.isAvailable()` in some cases return synchronously (when whisper isn't
set up), in other cases asynchronously. This actually breaks our demo application for
the following reason:
We check for Whisper's availability via:
```
EmbarkJS.Messages.Providers.whisper.getWhisperVersion((err, _version) => {
if (err) {
return console.log(err);
}
this.setState({whisperEnabled: true});
});
```
There's a couple of problems here:
- This code will break right away when whisper isn't available, resulting in an error:
```
Cannot read property _requestManager of undefined
```
- The reason this error happens is because there's no `web3` object available inside
our EmbarkJS.Messages code. Even though there **is** a web3 object, EmbarkJS.Messages
doesn't know about this because it only sets it when its `setProvider()` API is called,
which effectively doesn't happen at all when Whisper isn't enabled on the connected
node
- While this could be fixed with a simple check on whether EmbarkJS.Messages' internal
`web3` references is a thing, really what should be used in the demo is the `isAvailable()`
API.
`isAvailable()` should always return a promise (similar to `EmbarkJS.Storage.isAvailable()`.
This commit ensures that `isAvailable()` always returns a promise and changes the demo
template to use `isAvailable()` over `getWhisperVersion()`.
Make the adjustment even if the test script is currently disabled. Consistently
use nyc to generate coverage with mocha even if the test script is currently
disabled.
Add support for ability to start and stop Swarm via command `service swarm on/off`.
Fix issue with swarm not starting due to missing web3 object.
`service swarm on` - starts a swarm node if not already started. Shows an error if the node is already starting or started.
`service swarm off` - kills the running swarm node as long as Embark has started the swarm process. If the swarm process was started externally, an error is shown.
If a package uses only `.js` then supply `--extensions ".js"`. If a package
uses only `.ts` then supply `--extensions ".ts"`. If a package uses both, then
supply `--extensions ".js,.ts"`.
The reason for this is that adding/removing TS/JS support ought to occasion
revising a package's `package.json` file and adjusting other scripts as well,
e.g. for linting. With these changes, it won't work to simply start adding
`.ts` files in a package's `src/` directory, which should prompt the developer
to review `package.json` and make the appropriate changes, and/or other
developers may realize changes need to be made during code review.
Implement scripts to collect coverage reports (JSON format) from all packages
in the monorepo that generate such reports. Reports are copied to
`<root>/.nyc_output/coverage-[pkg-dir-name].json`.
Implement scripts to generate a combined html report in `<root>/coverage`.
Adjust root `reset` and `clean` scripts to delete `<root>/.nyc_output` and
`<root>/coverage`.
Implement a script in `<root>/package.json` to generate a `text-lcov` report
and upload it to coveralls from CI builds. Remove coveralls from
`packages/embark`.
Supply `packages/embark` with an nyc configuration in its `package.json` and
have its `"test":` script generate both `json` and `html` reports.
Use nyc with `embarkjs`'s test suite: supply an nyc configuration in its
`package.json` and have its `"test":` script generate both `json` and `html`
reports.
Adjust `embarkjs`'s tests for more accurate coverage reporting.
