JS & TS FeaturesLesson 38Free preview

Node TypeScript

This lesson is part of Node.js · All levels

Summary

TypeScript can be used directly in Node.js projects via a tsc compiler or a modern loader such as tsx. With static data types, errors such as misnames of properties are caught before the code is executed. The node also supports erasable syntax so that some TS files can be executed directly in the latest version.

Key points

Install the typescript as devDependency and then create tsconfig.json
Tsc compiles .ts to .js before running Node
Tsx or ts-node allows running TS directly during development
Type helps the IDE provide autocompletion and early bug detection
