Is inspecting import.meta.url a reliable way to distinguish browser and deno contexts?
I have been trying to figure out a good pattern to import JSON that will work whether called in deno or the browser. This is what I was thinking:
```js
let data
...
npm package, need to use deno websocket if running in deno
Anyone has any idea how to use native deno websocket with my npm package?
Detecting deno is not a problem.
(normal websocket from npm is broken in deno.)...
Fetching Twitter data with coroutines and puppeteer
are there any recent examples of how to fetch Twitter data (like monitoring activity for a keyword everyday) without using Twitter paid API and without getting blocked ? In Deno of course.
Custom JSX transform from local module
Is it possible to define a JSX transform within the same codebase? All of the examples show referencing it from a remote module like
https:/esm.sh/preact
I've tried this, but it is unable to load my local jsx-runtime module because it doesn't recognize it as bing JS or TS.

embed typescript playground to web page
some programming language guides like the rust book lets you directly edit and run code in their docs, would it be possible for deno to do this in client-side?
i'm planning to create a blog in deno and being able to run code snippets inside posts would be helpful.

Using deno-lambda for AWS SAM

importing scoped NPM packages from other registries
In node, I can create an
.npmrc that has rules like this:
```
@custom:registry=https://npm.example.com/

why is this a problem?
I have an npm dependency in a remote deno module that I am importing.
I would make a small reproducible example, but cannot really if I do not know what is causing it...
Embedding, snapshotting, and 7-bit ascii requirement
What are the differences in how a code module is processed when using
load_side_module() versus when building an extension and using .esm() and include_js_files!()?
I have an embed scenario working as expected with a JavaScript module, but less efficiently than I'd like (I suppose). I'd like to make it more efficient using snapshotting, but I'm hitting roadblocks that I don't understand. (Details follow...)...Standard setup of a monorepo that includes frontend and backend TypeScript code for one app
Hello friends, I'm new to Deno and have what I feel is a relatively simple use case, but I've struggled to find good guidance about it.
My repo is here: https://github.com/timschwab/chesswar. Nothing too fancy, messing about with WebSockets and <canvas>. I used to have two repos - one for the backend server and one for the frontend server. But I decided to just join them into one repo, so I could trivially share some code and types between the server code and the client code.
However this means that the VSCode workspace includes both Deno server code and frontend TypeScript, and so I don't know the right way to set
target and lib....How can I import https://github.com/ensdomains/ensjs-v3/tree/main in my deno

I want to be able to start deno from a command line, but be able to attach to it from VSCode.
I actually have that much working, but there is one issue - if I disconnect the debugger, I cannot reattach it.

Hey I am currently trying to understand the communication between a dll and my TS program. Currently I am simply trying to pass a string to the dll and have the dll give me the string back. Similar to an echo. I have been trying to follow this guide for this: https://medium.com/deno-the-complete-reference/calling-c-functions-from-windows-dll-in-deno-part-2-buffers-131226acd3d2 only somehow I can't pass the buffer in my TS program. Can someone give me a simple example of how to pass a string from TS to dll and from dll to TS?
```ts
const dll = Deno.dlopen('./test.dll', {
'echo': {...

Reading a ReadabeStream without consuming it?
Hi,
I'm trying to migrate an HTTP/HTTPS proxy protocol server from Node.js to Deno.
The proxy listens for TCP connections, and I need to handle HTTP and HTTPS connections differently, so the first think I do is to read the first byte of every new connection to determine if it starts with "22" (which means that it is a TLS handshake).
