TypeScript
TypeScript is an open-source programming language developed and maintained by Microsoft. It is a strict syntactical superset of JavaScript, and adds optional static typing to the language.
TypeScript is designed for development of large applications and transcompiles to JavaScript. As TypeScript is a superset of JavaScript, existing JavaScript programs are also valid TypeScript programs. TypeScript may be used to develop JavaScript applications for both client-side and server-side.
To get started with TypeScript installation, you need to first install Node.js in your system.
Node.js
Install Node.js https://nodejs.org/en/download/ https://en.wikipedia.org/wiki/Node.js
Node.js is an open-source, cross-platform JavaScript run-time environment that executes JavaScript code outside of a browser. Historically, JavaScript was used primarily for client-side scripting, in which scripts written in JavaScript are embedded in a webpage's HTML and run client-side by a JavaScript engine in the user's web browser. Node.js lets developers use JavaScript to write Command Line tools and for server-side scripting-running scripts server-side to produce dynamic web page content before the page is sent to the user's web browser. Consequently, Node.js represents a "JavaScript everywhere" paradigm, unifying web application development around a single programming language, rather than different languages for server side and client side scripts.
Installation
https://nodejs.org/en/download/package-manager/#debian-and-ubuntu-based-linux-distributions
curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - sudo apt-get install -y nodejs
Alternatively, for Node.js 10:
curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash - sudo apt-get install -y nodejs
You can check that Node.js was installed correctly by executing the following command in Bash:
node -v
The Node.js installer will install the node command in your machine but it will also install the npm command. You can also test that npm has been installed correctly by executing the following command:
npm -v
Optional: Install build tools. To compile and install native addons from npm, you may also need to install build tools:
sudo apt-get install -y build-essential
También hay que instalar ts-node:
sudo npm install -g ts-node
TypeScript Installation
As you have already installed Node, it's time to install the TypeScript Package using the Node Package Manager (NPM).
npm install -g typescript
Git Bash in Windows
Si estamos en Windows, tenemos que instalar Git Bash in Windows; que es tan sólo un terminal Bash en Windows.
Visual Studio Code
https://code.visualstudio.com/download/
https://en.wikipedia.org/wiki/Visual_Studio_Code
Visual Studio Code is a source code editor developed by Microsoft for Windows, Linux and macOS. It includes support for debugging, embedded Git control, syntax highlighting, intelligent code completion, snippets, and code refactoring.
Installation
Download the <file>.deb: https://code.visualstudio.com/download Installation: https://code.visualstudio.com/docs/setup/linux
Setting up a Node.js + TypeScript development environment
Compilation
Para preparar el directorio, primero hay que ejecutar:
tsc --init
npm init npm init --y (podemos ejecutarlo así para responder (yes) automáticamente a las preguntas.
Luego:
npm install @types/node
npm install jquery
tsc -p tsconfig.json
node demo.js
ts-node demo.ts
