TypeScript cheatsheets and tips

---

A small collection of cheat sheets and tips I've gathered during my studies and work on various projects. It includes all the main sections and subtopics of the TypeScript language.

Contents

• Installation
• Usage

Installation

1. Clone the repository:

git clone https://github.com/labattaria/typescript-cheatsheets.git

2. Install project dependencies:

cd typescript-cheatsheets
npm install

It will install all the necessary dependencies, including the reflect-metadata library, which is required for the decorators section (the last one).

Usage

We will need the following for the work:

• Install Node.js if it is not already installed. Preferably the LTS version, which is recommended for everyone. It rarely causes any issues.
• Install TypeScript globally by simply running:

npm install -g typescript

• Additionally, install the ts-node package by running:

npm install -g ts-node

To start the compiler (TS => JS), run the following command:

tsc ${path to the file .ts}

To create a configuration template, run the following command:

tsc --init

To quickly view the results of the code (quickly compile a specific file), run the following command:

ts-node ${path to the file .ts}

But mostly, it's just ready-made code and helpful tips for each section and subtopic of the TypeScript language. Each folder is a separate section of the language, and the files inside represent subtopics of that section. They contain ready-made snippet code solutions with brief descriptions. Each folder contains a subfolder called 'tasks' — these are comprehensive exercises that combine multiple subtopics and techniques from the corresponding section.
