All “standard” and valid JavaScript is also valid TypeScript. It’s a flexible superset of JavaScript with ways to describe optional data types. The primary benefits of using TypeScript are to catch more errors before they go into production and make it easier to work with your code base. As with any software project, a healthy team culture that includes a peer review process can improve quality and guard against issues that can creep into a project. However, larger JavaScript projects demand tools such as ESLint to catch common mistakes, and greater discipline to saturate the code base with useful tests. Language features added to ES2015 and beyond have significantly improved its utility and reduced common frustrations of writing applications. The Case for TypeScriptĪs a web developer, I long ago stopped resisting JavaScript, and have grown to appreciate its flexibility and ubiquity. The goal of this tutorial is to show you how to build a new Node.js application using TypeScript and Express. Node.js server applications can benefit from using TypeScript, as well. More and more teams are turning to TypeScript to supplement their JavaScript projects. Today, building JavaScript applications at scale remains a challenge. In that time, JavaScript usage has grown from small user experience enhancements to complex full-stack applications using Node.js on the server and one of many frameworks on the client such as Angular, React, or Vue. Or create a nodemon.Like it or not, JavaScript has been helping developers power the Internet since 1995.
I was struggling with the same thing for my development environment until I noticed that nodemon's API allows us to change its default behaviour in order to execute a custom command.įor example, for the most recent version of nodemon: nodemon -watch "src/**" -ext "ts,json" -ignore "src/**/*.spec.ts" -exec "ts-node src/index.ts" ts file and it will Just Work: nodemon app.ts
You can now simply npm install -save-dev ts-node nodemon and then run nodemon with a.
