If your project requires more flexibility in how your files are executed, nodemon allows users to create a configuration file to meet a project’s exact specifications.

The inbuilt nodemon TypeScript runner provides a method to get up and running with minimal setup: manual configuration. Many projects require more than just the default tsc TypeScript compiler that is used by ts-node, and still others will require more advanced configuration if this scenario describes your needs, proceed to method two.
However, this method falls short in terms of flexibility and customization. It’s built into nodemon itself, so all that is required is installing the necessary packages. This method is by far the most simple, as it requires minimal setup. Once both of these dependencies are installed, you can pass a TypeScript file to nodemon as you would a JavaScript file. Since both of these packages will likely only be used during development, they should be installed as devDependencies. In addition, ts-node must be installed in your project. This method requires a version of nodemon ≥1.19.0 to be installed. ts-node serves as drop-in replacement for the node CLI, so the same arguments can be passed to the ts-node CLI as the node CLI. Ts-node is a TypeScript execution engine that compiles and runs TypeScript files. By default, nodemon uses the node CLI as an execution program for running JavaScript files for TypeScript files, nodemon uses ts-node as the execution program instead. Method 1: No-config workflowĪs of v1.19.0, nodemon has inbuilt support for TypeScript files with help from ts-node that requires no manual configuration. Since each option has its own pros and cons, we will discuss whether or not each option will suit the needs of our project, and if not, which option is a better choice.
We will also review three nodemon alternatives with extra features and more customizability, if you are looking for alternatives to nodemon that will better fit your project’s requirements. But fear not! In this article, we’ll review three methods of configuring nodemon, each of which offers different features and functionalities that can meet the needs of your TypeScript project. Well, the simplicity offered by nodemon diminishes both as you introduce TypeScript into your project, and as the complexity of your project grows. For example, if you have a project with an index.js file that you want to quickly test and iterate on, you can run nodemon index.js, and a new Node.js execution process will begin for index.js, restarting whenever a file in the project is updated. Nodemon is a CLI for Node.js that makes JavaScript development much quicker by restarting an execution process when a file is updated.
