问题 I am going to update some fields of mongoose document according to provided keys. For example, When we present mongoose document in json. user: { address: { city: "city" country: "country" } } And update params is given like this. address: { city: "city_new" } when I run the mongoose api like this. let params = { address: { city: "city_new" } } User.set(param) It replace whole address object and final result is user: { address: { city: "city_new" } } it just replace address field, but I want

问题 Is there a way to pass options to node when invoking ts-node? I am trying to use an experimental feature in node and it would be swell if it would work with ts-node. This is currently what I am doing: ts-node ./src/utils/repl.ts -- --experimental-repl-await 回答1: I got it to work this way: node --experimental-repl-await -r ts-node/register ./src/utils/repl.ts From the ts-node documentation: Note: If you need to use advanced node.js CLI arguments (e.g. --inspect ), use them with node -r ts-node

问题 I am currently trying to get rounded corners on an Electron application I'm making. I have tried nearly every solution available on-line at the moment, but none of them make any difference. How can I round the corners of my Electron app? 回答1: Make a frameless transparent window const myWindow = new BrowserWindow({ transparent: true, frame: false }) And have something like this in the renderer, or apply the style directly to the body tag <div style="width: 500px; height: 500px; border-radius:

问题 From the node docs regarding the creation of typed arrays from Buffers: The buffer's memory is interpreted as an array, not a byte array. That is, new Uint32Array(new Buffer([1,2,3,4])) creates a 4-element Uint32Array with elements [1,2,3,4] , not an Uint32Array with a single element [0x1020304] or [0x4030201] . This contrasts to plain javascript, where creating a typed array view from an ArrayBuffer uses the ArrayBuffer's memory as bytes (like a reinterpret_cast in C++). I need this behavior
