But browsers don't support top-level await yet. So we need to put it all inside as async function.

Configuring CommonJS & ES Modules for Node.js
Note that ESM is not “backwards” compatible with CJS: a CJS module cannot require() an ES Module; it is possible to use a dynamic import (await import()), but this is likely not what consumers expect (and, unlike ESM, CJS does not support Top-Level Await).

Node v14.8+: Top Level Async Await
With the latest node version(s) (v14.8+), we should be able to rewrite the above code to something like this. proposal-top-level-await

What is a practical example of using a Promise? These Youtube tutorials are bogus
Now a days, you'll likely mostly use async/await. The few cases where you'll need the Promise API (then()'s etc.) is when you're outside of an async function. With the new top-level await feature coming to modules, you wouldn't even need it outside of async functions in module code which will make its usage even less common.

Basic import question
The await is in top level. The top level await proposal is in stage 3. Currently, the browser support is also not good enough but should work in latest version of the google chrome browser.

Rust's async isn't f#@king colored!
There is a proposal for top-level await in JS. I'm guessing this would effectively kinda do the same thing? Or am I wrong there?

Use Notion as your CMS along with Next.js
During my search for deploying Lambdas via GitHub actions, I came across a tutorial that utilized ncc for converting TypeScript and bundling. While ncc is effective, I discovered esbuild, which proved to be significantly faster and perfectly suited to my requirements.

Build a Vite 5 backend integration with Flask
Unlike Webpack, the Vite DevServer only compiles files when they are requested. It leverages ES module imports, which allow JS files to import other files without needing to bundle them together during development. When one file changes, only that file needs to be re-compiled, and the rest can remain unchanged. Project files are compiled with Rollup.js. Third-party dependencies in node_modules are pre-compiled using the ultra-fast esbuild bundler for maximum speed, and they are cached until the dependency version changes. Vite also provides a client script for hot module reloading.

How to run TypeScript natively in Node.js with TSX
TSX is the newest and most improved version of our ts-node, using ESBuild to transpile TS files to JS very quickly. The most interesting part is that TSX was developed to be a complete replacement for Node, so you can actually use TSX as a TypeScript REPL, if you install it globally with npm i -g tsx, just run tsx in your terminal and you can write TSX natively. But what's even cooler is that you can load TSX for all TypeScript files using --loader tsx when you run your file. For example, let's say we have this file called index.ts:
