Nodejs typescript
npm install types/lib1 types/lib2 -save-dev. This will add the tsconfig.json file to your project. Our goal here is to be able to use Typescript to develop our application quickly, but ultimately we want our application to compile down to plain old javascript to be executed by the nodejs runtime.
#NODEJS TYPESCRIPT HOW TO#
In this post, we learn how to add Typescript to the mix. Next, we should initialize our project as a Typescript project. Express is the most ubiquitous framework for nodejs. Also for each of your third party libs: yarn add types/lib1 types/lib2 -dev. npm install types/node types/express types/body-parser types/mysql types/dotenv -save-dev. Using TypeScript with Node.js gives you access to optional static type-checking along with robust tooling for large apps and the latest ECMAScript features. Wanted to mention as well that the spec for NodeJS.Timeout includes (): number: interface Timeout extends Timer )) Īwait screen.findByText('Current Count: 15') Įxpect(screen.getByText('Current Count: 15')). Now after you've done the above, time to install the Typescript and the types for you libraries.
