This is an example of a simple GET API call wrapped in a promise to take advantage of its asynchronous functionality. var get = function(path) { return new Promise(function(resolve, reject) { let request = new XMLHttpRequest(); request.open('GET', path); request.onload = resolve; ...

Main process source code index.js: const {app, BrowserWindow, ipcMain} = require('electron') let win = null app.on('ready', () => { win = new BrowserWindow() win.loadURL(`file://${__dirname}/index.html`) win.webContents.openDevTools() win.on('closed', () => { win = null ...

You can make code run asynchronously from the main thread using runTaskAsynchronously. This is useful for doing intensive math or database operations, as they will prevent the main thread from freezing (and the server from lagging). Few Bukkit API methods are thread-safe, so many will cause undefin...

Create index.js as const {app, BrowserWindow, ipcMain} = require('electron') let win = null app.on('ready', () => { win = new BrowserWindow() win.loadURL(`file://${__dirname}/index.html`) win.webContents.openDevTools() win.on('closed', () => { win = null }) }) ipcM...

If you want to execute synchronous code asynchronous (for example CPU extensive calculations), you can use Task.Run(() => {}). public async Task DoStuffAsync() { await DoCpuBoundWorkAsync(); } private async Task DoCpuBoundWorkAsync() { await Task.Run(() => { fo...

Simulation environments A simulation environment for a VHDL design (the Design Under Test or DUT) is another VHDL design that, at a minimum: Declares signals corresponding to the input and output ports of the DUT. Instantiates the DUT and connects its ports to the declared signals. Instant...
