## User reported error
i recently updated to embark 5.0 im having issues connecting to a local node each time i connect to it i get the following output from the embark console
```
Error during proxy setup: Port should be >= 0 and < 65536. Received 754510.. Use '--loglevel debug' for more detailed information.
```
This is what i have under the blockchain.js file
```
localDev: {
endpoint: "http://127.0.0.1:7545",
accounts: [{
nodeAccounts: true,
}]
}
```
### Problem
The port to start the proxy on is incremented by a constant value (using the `+` operator), however the port comes from the config and in the case where it is a string, the `+` operator acts as a string concatentation.
### Fix
Ensure the port from the config is always parsed to a number before attempting to add the constant proxy port offset.
Remove the `<12.0.0` restriction re: Node.js version in the `"engines"`
settings for all the packages in the monorepo that had that restriction.
Add missing `"engines"` settings in `packages/plugins/snark/package.json`.
Adjust the Azure Pipelines config to include builds for Node.js v12.x and
v13.x.
Bump `solc` to `0.4.26` in `dapps/tests/app` and `dapps/tests/contracts`. It
was discovered that older versions suffered a fatal `Maximum call stack size
exceeded` error when run on Windows with Node.js v12.x or newer. Display a
warning re: the bad combo (solc version + Windows + Node version) if it's
detected at runtime.
Adjust the root `yarn.lock` so that the `sha3` transitive dependency resolves
to a newer version that is compatible with Node v13.x.
When running tests that expect the EVM to fail, Embark's proxy keeps logging
the VM errors to stdout making it look like tests weren't successful, while they
are actually passing.
Inside a test-runner it's probably expected not to see any error logs when the
tests in question expect errors.
This commit changes the proxy to use `debug()` logs instead of `error()`, making
it configurable through log verbosity how much errors are seen.
Refactor typings as necessary. In order for `bignumber.js` in the root
`node_modules` to not conflict with `@types/bignumber.js`, specify
`"bignumber.js": "5.0.0"` in `devDependencies` and `"embark-ui/bignumber.js"`
in `nohoist` of the root `package.json`.
In `packages/plugins/rpc-manager` switch from callback to promise usage with
respect to `web3.eth.accounts.signTransaction` because of a [bug][bug]
discovered in web3 v1.2.4.
In `packages/plugins/solidity-tests` specialize the tsc compiler options with
`"skipLibCheck": true` because of a problematic web3-related typing in the
`.d.ts` files of the remix-tests package.
Bump ganache-cli from 6.4.3 to 6.7.0 (latest) because 6.4.3 doesn't support
`eth_chainId` but web3 1.2.4 makes use of the `eth_chainId` RPC method (EIP
695).
BREAKING CHANGE: bump embark's minimum supported version of parity from
`>=2.0.0` to `>=2.2.1`. This is necessary since web3 1.2.4 makes use of the
`eth_chainId` RPC method (EIP 695) and that parity version is the earliest one
to implement it.

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.

When `eth_unsubscribe` is received in the proxy, ensure this request is forwarded through on the correct socket (the same socket that was used for the corresponding `eth_subscribe`).
Move subscription handling for `eth_subscribe` and `eth_unsubscribe` to RpcModifiers (in `rpc-manager` package).
For each `eth_subscribe` request, a new `RequestManager` is created. Since the endpoint property on the proxy class was updated to be a provider, the same provider was being assigned to each new `RequestManager` and thus creating multiple event handlers for each subscription created. To circumvent this, we are now creating a new provider for each `RequestManager`.

This PR adds support for EIP-712 (https://github.com/ethereum/EIPs/blob/master/EIPS/eip-712.md), by allowing the signing of typed data transactions using the `eth_signTypeData_v3` or `eth_signTypedData` request.
Add a module called `embark-rpc-manager` to handle all RPC transaction modifications.
The internal events management module extracted to `embark-core`. This allows other modules (ie plugins) to use a private instance of Embark’s event API.
Remove transaction modifications in `embark-accounts-manager` and leave only the functionality in this module that handle account management (ie funding of accounts). Other functionality was moved to `embark-rpc-manager`.
- Transactions should now reflect when a new node account is added via `personal_newAccount` or via the node itself (and once `eth_accounts` is requested).
- In the proxy, errors are handled for all cases and are now JSON-RPC spec-compliant.
- Always register `eth_signTypedData` RPC response and display error message if account cannot be found.
NOTE: Updated yarn.lock due to conflict after rebase.
Avoid race condition with rpc modifications
Refactor proxy to make request handling asynchronous, and to allow circumvention of forwarding requests to the node in cases where it is not needed.
Move loading of plugins to after core and stack components (in cmd_controller).
We should load custom plugins LAST (ie after all core and stack components, and after all Embark plugins). To do this, we disable automatic loading of plugins in the config, and allow them to be loading explicitly in cmd_controller.
Create a system that allows registration of custom plugins. Each plugin is generated in EmbarkJS by instantiating the registered class. For example, we can register a Plasma plugin and it will be generated in to EmbarkJS.Plasma with an instantiation of `embarkjs-plasma`. The DApp itself can then do what it wants with `EmbarkJS.Plasma` (ie call `EmbarkJS.Plasma.init()`.
NOTE: loading of custom plugins needs to be applied to all other commands in `cmd_controller`. This PR only loads custom plugins for the `run` command.
NOTE: This PR is based on branch fix/ws-eth-subscribe (#1850). I will rebase this PR when (and if) #1850 is merged.
Fix the proxy’s handling of WebSocket connections when subscribing to contract events and node data using the `eth_subscribe` RPC request.
Previously, the client connection that the subscription data was sent to was often in a closed state. It was determined that this connection was the wrong connection to forward the data in the first place. The connection was in fact generally the connection created for the Ethereum service check which was then (correctly and subsequently) closed after it had finished its operation.
The flow of a proxy request handling a WebSocket “eth_subscribe” RPC request is now as follows:
1. A WebSocket RPC request `”eth_subscribe”` is sent from a client to the proxy.
2. Proxy forwards the request to the node by way of a new instance of `RequestManager`.
3. When the node receives an event matching the subscription, it sends the event data back to same socket connection it received the request on (ie the specific instance of `RequestManager`).
4. The `RequestManager` fires the `”data”` event containing the subscription data, and this event is picked up in the proxy.
5. The proxy then forwards the subscription data on to the originating WS client connection.
All other requests (ie non-WS or WS RPC requests that are not `eth_subscribe`) will be serviced to/from the node using a single `RequestManager` instance.

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.
