Test using png mocks

When using imports with *.png files it will crash denos testing system with a warning:

error: Expected a JavaScript or TypeScript module, but identified a Unknown module. Importing these types of modules is currently not supported.
  Specifier: file:///home/zweieuro/Documents/uni/2023_SS/WUI/html_UI/vivaci_ui_deno/client/src/player_life.png

While I understand the problem, how can i mock away the png and replace it with an identity object or something similar? In jest i would transform it away (https://stackoverflow.com/questions/46898638/importing-images-breaks-jest-test) but i am not sure how deno would handle this

Import module from gitlab server

Hi! I want to import an npm module from my private gitlab server, the server and module itself do not require an auth tokenand are publibly accessible. How do i add it to deno ? If possible I want to avoid adding my own server to my npmrc and then importing it. Found this: https://docs.deno.com/runtime/fundamentals/node/#how-to-use-private-registries-with-deno is this really necessary ? because the example only specifies 'private' repos, which does not apply to mine, i don't need a token

Build a React app with a starter template incorrectly setup

Hi! After running the setup for the react template https://docs.deno.com/examples/react_tutorial/ there are some errors that VSCode reports. Mainly that main_test.ts for the server can't find packages specified in:

import { afterAll, beforeAll, describe, it } from "jsr:@std/testing/bdd";
import { expect } from "jsr:@std/expect";

import { afterAll, beforeAll, describe, it } from "jsr:@std/testing/bdd";
import { expect } from "jsr:@std/expect";

which is weird since this is the started template. Is this an error of my setup or a problem of deno ?

Intellisense not working for typescript react.

I ran this to create a new Vite React project: What I did:

deno run -A npm:create-vite@latest --template react-ts
deno install
deno task dev

deno run -A npm:create-vite@latest --template react-ts
deno install
deno task dev

But the type sensing was wrong, there also was no deno.json so i created one:

{
  "imports": {
    "react": "npm:react@^18.3.1",
    "react-dom": "npm:react-dom@^18.3.1"
},
"compilerOptions": {
    "lib": [
      "dom"
    ],
    "jsx": "react-jsx",
    "jsxImportSource": "react",
    "types": [
      "npm:@types/react",
      "npm:@types/react-dom"
    ]
}}

{
  "imports": {
    "react": "npm:react@^18.3.1",
    "react-dom": "npm:react-dom@^18.3.1"
},
"compilerOptions": {
    "lib": [
      "dom"
    ],
    "jsx": "react-jsx",
    "jsxImportSource": "react",
    "types": [
      "npm:@types/react",
      "npm:@types/react-dom"
    ]
}}

But the type sensing is still wrong, for very simple code like const [count, setCount] = useState<number>(0); VsCode does not detect count or setCount to be of type number, and it complains that useState has no type argument.

Start a new Vite React project

Hi! Should https://docs.deno.com/runtime/tutorials/how_to_with_npm/react/ work out of the box? I am trying to get it to run with vscode but even if it runs there are a lot of small problems with it out of the box: - svgs are not recognized as valid resources - the react UMD is missing so everything is recognized as an error - doesn't generate a deno.json for me at all - seems in general that a lot of types and intellisense are setup incorrectly ? I have no other plugin active other than dino What I did:

deno run -A npm:create-vite@latest --template react-ts
deno install
deno task dev

deno run -A npm:create-vite@latest --template react-ts
deno install
deno task dev
