Functions

checkClockSync

▸ checkClockSync(): Promise<CheckClockSyncResult>

Defined in checkClockSync.ts:21

Use SNTP to check if the local clock is synchronized; return the time drift.

Returns: Promise<CheckClockSyncResult>

defaultParityPath

▸ defaultParityPath(): Promise<string>

Defined in getParityPath.ts:23

The default path to install parity, in case there's no other instance found on the machine.

Returns: Promise<string>

deleteParity

▸ deleteParity(): Promise<void>

Defined in fetchParity.ts:84

Remove parity binary or partial binary in the userData folder, if it exists.

Returns: Promise<void>

fetchParity

▸ fetchParity(mainWindow: BrowserWindow, options?: FetchParityOptions): Promise<string>

Defined in fetchParity.ts:106

Downloads Parity, saves it to Electron's userData folder, and returns the path to the downloaded binary once finished.

Parameters:

Param	Type	Default value
mainWindow	`BrowserWindow`	-
`Default value` options	FetchParityOptions	{onProgress: () => {/ Do nothing by defaut. /},parityChannel: 'beta'}

Returns: Promise<string>

getParityPath

▸ getParityPath(): Promise<string>

Defined in getParityPath.ts:104

Returns the path to Parity, or throws if parity is not found.

Returns: Promise<string>

isParityRunning

▸ isParityRunning(options?: IsParityRunningOptions): Promise<boolean>

Defined in isParityRunning.ts:20

Detect if another instance of parity is already running or not. To achieve that, we just ping on the common hosts.

Parameters:

Param	Type	Default value
`Default value` options	IsParityRunningOptions	{wsInterface: '127.0.0.1',wsPort: '8546'}

Returns: Promise<boolean>

killParity

▸ killParity(): Promise<void>

Defined in runParity.ts:118

If a Parity process has been spawned with runParity, then it kills this process. However, there's no guarantee that Parity has been cleanly killed, and the Promise resolves instantly.

Returns: Promise<void>
