Possible to use CsvParseStream in Node.js

need to check. Up until now I thought you were using Deno's LSP

Oh so the issue is that you're getting the type error with plain ts and not with Deno's LSP?

I'm not sure at the top off my head how to resolve that error, but you could also go with the Deno-native version when you're using Deno in the first place:

import { CsvParseStream } from "@std/csv";

const source = await Deno.open("./data.csv");

const stream = source.readable
  .pipeThrough(new TextDecoderStream())
  .pipeThrough(new CsvParseStream({ skipFirstRow: true }));

import { CsvParseStream } from "@std/csv";

const source = await Deno.open("./data.csv");

const stream = source.readable
  .pipeThrough(new TextDecoderStream())
  .pipeThrough(new CsvParseStream({ skipFirstRow: true }));

Deno Monorepo with nested applications and packages

Right, nested workspaces are not supported in Deno. Relevant issue https://github.com/denoland/deno/issues/26879

`<details>` element cannot have the basic "name" property?

Looks like we missed that in the typings for Preact. PR with the fix: https://github.com/preactjs/preact/pull/4766

Use deno serve for tcp

yes, you're correct. iirc Deno.connect() is the way to go for tcp stuff but it doesn't have the automatic threading that deno serve --parallel gives you

making a cli with arrow keys for navigating prior commands

The secret is ansi codes which are special character combinations in terminals that allow you to clear previous lines or move the cursor, see https://tldp.org/HOWTO/Bash-Prompt-HOWTO/x361.html

TypeError [ERR_STREAM_NULL_VALUES]: May not write null values to stream

We usually make the distinction between Deno the CLI and Deno Deploy. In the past many users reported Deno Deploy issues in that tracker
