An example of a TypeScript Method Decorator, also known as an "annotation" in other languages.

You can use a decorator like @Decorator on a method inside of a class.

export function Decorator <Args extends any[], Result extends any> (target: Object, propertyKey: string, descriptor: TypedPropertyDescriptor<(...args: Args) => Result>) {
  const originalMethod = descriptor.value // save a reference to the original method
  // NOTE: Do not use arrow syntax here. Use a function expression in 
  // order to use the correct value of `this` in this method (see notes below)
  if (originalMethod) {

http

method

export type Method =
  | 'get'
  | 'options'
  | 'post'
 | 'put'

A simple live-reload implementation that refreshes the page when the source file changes on disk.

The server.js file just serves the files in the directory that it is in, including itself. It also ensures that a private Cache-Control header is set for GET requests, and caching disabled for other HTTP methods.

The index.html file contains a hand-rolled live-reload script that polls the server every 2 seconds and honors the HTTP 304 response code and the caching and etag directives specified by

typed-string-splitter

What the built-in string 'some cool string'.split(' ') does:

--> converts 'some cool string' to ['some', 'cool', 'string'] with a resulting type of string[]

What you can do with TypedSplit('some cool string', ' ') from this gist:

--> converts 'some cool string' to ['some', 'cool', 'string'] with a resulting type of ['some', 'cool', 'string']

unzipping a `.gz` file

On Linux and MacOS, a .gz file can be decompressed using the gzip command.

For example:

gzip -d log.gz

banner

Shows a banner on the CLI using a cool font.

For NodeJs & TypeScript. Depends on the amazing figlet and chalk libraries.

import figlet from 'figlet'
import chalk from 'chalk'

typescript config

Make sure to install the following dependencies for the best experience.

npm install --save tslib
npm install --save-dev typescript
npm install --save-dev ts-node

	// make sure you `npm install twilio` before you run

	const config = {
	// get your credentials from the twilio console: www.twilio.com/console
	// can also be configured as environment variables instead
	accountSid: '<twilio account sid>',
	authToken: '<twilio auth token>',
	// on a twilio trial account, you can only send from and to confirmed or purchased numbers
	// upgrade your account to send to any number
	from: '+10000000000',

	#!/usr/bin/env node

	/* The API routes and middlewares */
	const server = () => import('express').then(({ default: express }) => {
	const app = express()
	app.get('/hello', (req, res) => {
	res.json({ message: 'Hey there!' })
	})
	return app
	})
