Cannot assign number to "number | undefined" when using package.json

Hi. I'm having odd behavior when using a newly created Vite vanilla TypeScript template using deno init --npm vite@latest. Right after initialization I'm installing the game library https://www.npmjs.com/package/excalibur. A game object in the engine is written like this: ```ts import * as ex from "excalibur"; class GameObject extends ex.Actor {...

How do deno devs bundle .js for browser projects? (SPAs, chrome extensions, etc)

Is the easiest option to tell deno to emit a node_modules subdirectory so I can use esbuild? I'm trying to minimize configuration as much as possible.

Is assertObjectMatch too type-strict?

If you have two typed objects, actual and expect, of the same type, assertObjectMatch doesn't let you use the expect object: ```ts import { assertObjectMatch } from '@std/assert'; ...

React types without @deno-types before every import?

I'm hoping someone can clear up a little snag for me. Is it actually necessary to include // @deno-types="npm:@types/react" above every single react import in every single file? I'm up-to-date with deno, I've got npm:@types/react in my types property of my compiler options, etc. I've been perusing issues and trying alternatives for hours, but it seems like this is the only option that actually works: ```

deno --version

deno 2.1.5 (stable, release, aarch64-apple-darwin)...

how do I use `@ts-self-types` without `.d.ts` files appearing in docs?

I have this package here: https://jsr.io/@samual/duration/0.0.1-85380af Which has been uploaded as pairs of .js and .d.ts where the .js files have // @ts-self-types="…" comments at the top. And to make sure the Deno type checker can find the .d.ts files, they are all in the jsr.json's "exports" array....

TestContainers are broken in Deno.

I'm was trying to set up testcontainers https://testcontainers.com/ in deno. Their SDK makes a socket connection to local docker using node http. However, this same connection is broken in deno. I'm just wondering if it's my machine or something is wrong with node:http. Here is more info https://github.com/denoland/deno/issues/27675

Super slow LSP with Deno + VSCode

We experience a really degraded DX in our IDE (VSCode) since we migrated to Deno 2.1.2. We have a Deno workspace with some backend services and a React SPA built with Vite. - Slow start (lots of "Loading...") - Blinking stuff (colors change, underlines, inferred types...) - Slow (lots of "Loading...") when we open a file for the first time....

Deno compile with SupaBase doesn't work

I created a little authentication client that works on deno very well, connecting to a supabase istance. However, when i compile the code, it doesn't work. It seems to be unable to compile Typescript into JS for some reason.

Is Deno a good JS runtime for embedding into another application?

Hi, I am looking for a Js runtime that I could easily embed into my application. I would like to allow scripting for the users of my application to extend its capabilities. The reason I am considering Deno is because of its security features. Is Deno a good candidate for this?...

How to customize daisyui default theme?

Hello, I'm trying to define a new value for the light theme for daisyui. The trouble I'm running into is with the tailwind.config.ts where I'm unable to use the require statement as directed in their docs to import the existing classes: https://daisyui.com/docs/themes/#-7. Not really sure where to go from here.

I need ideas for different ways to dig into the Deno API's and its standard library

I am new-ish to Typescript, but I have been a programmer for over a decade. I'm giving myself a challenge to do a new thing with Deno every day for 100 days. https://github.com/kimdcottrell/hundo-days-of-deno Over the next few days, I'm thinking I can test out: - Deno.connect() and the node-mysql2 lib...
