Hi Reddit, Suppose we have type GenFunc = <A = void, B = void>({ a?: A, b?: B }) => Promise<void> I have written a IIFE to return a function that does something depending on an external variable const num = 1 // substitue for an external variable const genFunc: GenFunc = (() => { switch (num) { case 1: return async ({ a, b }) => { console.log(a) console.log(b) await fetch("http://example.com") // just an awaited function, nothing to do with the code } case 2: ... ... ... default: return async({ body, params }) => {} } } })() I'm not able to access the a and b de ..read more

Thanks in advance for any replies. I'm new to Typescript and looking at migrating a JS app, and before I get too deep I want to make sure I really am supposed to write out every prop parameter twice. E.g. in JS: function GameList({ userId, sessionId, opt, mode }) { ... } In TS: type GameListProps = { userId: number, sessionId: number, opt?: any, mode?: string, }; function GameList({ userId, sessionId, opt, mode }: GameListProps) { ... } Now when I modify this in the future, I have to update two places and keep them in sync. I assume there's a good reason I'm currently missing? Like why ..read more

Hi, devs! I've been trying to achieve the following goal, but without success. I want to import object from a third party package, then use the keys as type and export the type. I want to build/compile (it is types only package in monorepo) and then use in other packages. Some of the imports are promises. Is there any good approach to do it? Here is quick pseudo code: import { someObject } from "awesome-package" type someType = { [P in keyof typeof someObject\]: boolean; } export { someType } submitted by /u/Devastion [visit reddit] [comments ..read more

It seems the documentation suggests they are practically the same, and it's a matter of developer preference. Is that really so, or are there some rare cases where there's an actual difference? Readonly<Type> example: interface Todo { title: string; } const todo: Readonly<Todo> = { title: "Delete inactive users", }; todo.title = "Hello"; // Cannot assign to 'title' because it is a read-only property. readonly Properties example: interface SomeType { readonly prop: string; } function doSomething(obj: SomeType) { // We can read from 'obj.prop'. console.log(`prop has the value ..read more

i know its a dumb question but i will ask anyway, imagine you can write code like this : //math.ts function add(x: number, y: number): number { return x + y; } //another.ts import type {add} from './math.ts' const foo : add and ts will extract the type definition from add function to foo const , and whenever i made change in add function thats will reflect with errors or warnings in 'another.ts' file ? submitted by /u/lorens_osman [visit reddit] [comments ..read more

I am searching for an alternative to Nest.js, but I haven't been able to find any framework that is as comprehensive as Nest. I'm looking for a solution that includes features such as Dependency Injection, ORM, Authentication, and Authorization. Are there any good alternatives to Nest or a suitable stack that meets these requirements that you would recommend? submitted by /u/alexandreqo [visit reddit] [comments ..read more
